Larvicidal activity of Menthe longifolia different extracts against lymphatic filariasis vector, Culex pipiens and Rift Valley Fever vector, C. antennatuswas tested. The extraction was carried out using methanol, acetone, chloroform and petroleum ether solvents. Obtained results revealed that petroleum ether extraction from leaves of M. longifolia was more effective against 3rd instar larvae of C. pipiens and C. antennatus than those of chloroform, acetone and methanol extractions. Methanol, acetone, chloroform and petroleum ether extracts from leaves of M. longifolia recorded LC50 values of 1741.5, 1322.0, 702.4 and 379.5 ppm against C. pipiens third larval instar and 1064.6, 850.3, 459.9 and 250.4 ppm against C. antennatusthird larval instar, respectively. In addition, LC90 values recorded 2282.0, 1897.7, 1300.3 and 511.9 ppm by methanol, acetone, chloroform and petroleum ether extract from leaves of M. longifolia against C. pipiens third larval instar and 1596.5, 1388.6, 979.4 and 388.2 ppm against C. antennatusthird larval instar, respectively. Also, both C. pipiens and C. antennatus larval and pupal periods were prolonged by all tested extracts at all concentrations used as compared with the untreated groups. Menthe longifolia tested extracts are considered as new promising controlling agents against C. pipiens and C. antennatus, however, more studies are necessary to reach the active ingredient in the tested extracts.

Mosquitoes have diverse species and global distribution. Most freshwater bodies support different mosquito species breeding. The physicochemical characteristics of mosquito breeding sites may influence culicine species distribution and their abundance. This study aimed to determine culicine species communities and their abundance in two rural sites and one urban breeding site in Egypt considering physicochemical characteristics of breeding places. These areas were Al-Beshlawy drainage canal (Giza), El-Khartoum irrigation ditch (Beheira), and Tanta man-made ground hole (Gharbia), respectively. The measured physicochemical parameters were temperature, pH, salinity, turbidity, dissolved oxygen, and nitrite. Diversity indices (recorded number of species, diversity, equitability, and concentration of dominance) of mosquitoes were also calculated. The results showed that six culicine species were identified in the tested three breeding sites. These were Culex pipiens, Cx. univittatus, Cx. antennatus, Cx. quinqueifasciatus, Cx. perexiguus, and Culiseta longiareolata. All species are native to the Egyptian fauna. In all tested urban and rural breeding sites, Cx. pipiens was considered eudominant. Bray-Curtis dissimilarity in the culicine community between the tested sites ranged between 0.03 and 0.12. This dissimilarity may be attributed to the absence of certain species in some sites, as well as the significant difference in the abundance of Cx. pipiens and Cs. longiareolata among the sites. Water salinity and dissolved nitrite content differed significantly among the breeding sites. The multiple regression analysis between the identified culicine species and the physicochemical parameters showed that salinity, nitrite content, turbidity, and pH are considered key factors to predict some culicine species in water bodies.

Aristeus antennatus is one of the most exploited and economically important resource for fisheries in the Western and Central Mediterranean Sea displaying low population differentiation with mitochondrial and microsatellite markers. The recent development of Genotyping-by-Sequencing (GBS) methods may contribute to the discovery of SNPs and the assessment of genetic differences between populations of this species for fisheries management. Using samples from four geographical sites in Western Mediterranean and Eastern Atlantic, 115,071 putative SNPs were detected. After the stringent quality control measures and the filtering procedure, 232 SNP loci were discovered. Finally, we selected 80 SNP subset panel for Fluidigm Dynamic array application. The results showed significant differentiation among populations from the four sampling sites. Population assignment power and patterns of population differentiation were comparable between the two SNP panels. These markers represent a useful tool for future genetic application of A. antennatus populations.

The present study investigated the larvicidal and repellent activities of Cestrum nocturnum (leaves) different extracts against Rift Valley Fever vector, Culex antennatus. The obtained results showed that the petroleum ether extract was the most effective extract against Cx. antennatus larvae followed by chloroform, acetone, and ethanolic extracts. The LC50 values of petroleum ether extract recorded 179.4, 164.2, and 148.7 ppm against Cx. antennatus third larval instar after 24, 48, and 72 h., respectively. On the other hand, at 6.67, 3.33, and 1.67 mg/cm2, ethanolic extract induced a degree of repellency equal to 93.1, 90.1, and 60.2% within the 4h post-treatment, respectively. Generally, petroleum ether extract proved high efficacy as repellents. At 3.33mg/cm2 petroleum ether extract produced the highest protection (100.0%) during the entire testing period of 4h post-treatment. Moreover, the protection (93.3, 90.7 and 80.8%) obtained at 2.67, 1.67 and 0.833 mg/cm2, respectively, compared with 100.0% repellency for DEET at a dose1.8 mg/cm2. So, Ce. nocturnum tested extracts can be considered as new promising controlling agents against the mosquito vector, Cx. antennatus.

International audience; In Madagascar, the high West Nile virus (WNV) antibody prevalence reported in horse populations suggests a high level of vector-horse contact. This study aims to characterize the mosquito species usually involved in WNV transmission in horse stables in Madagascar. Five horse stables were investigated in October and November 2016 in five distinct inland areas. Mosquitoes were collected using double net traps baited with human, poultry or horse as well as light traps. Blood meal identification from engorged females was performed using host-specific PCRs. A total of 2898 adult mosquitoes were collected with Culex (Culex) antennatus (Becker) (40.7%), and Cx. (Cux.) quinquefasciatus Say (14.9%), being the most abundant species. The mosquito abundance varied between horse stables (P < 10(-7)) and depending on the bait used in the double net traps (P < 0.003). Among the 190 tested blood meals, 119 consisted of single blood meals with 85 from horse, 17 from human, 16 from chicken, one from cattle and 71 consisted of mixed blood meals. The mosquito species collected during this study exhibited a generalist feeding behaviour allowing them to act as bridge vectors between different vertebrate hosts involved in WNV transmission cycle. Their vector status with regard to West Nile fever epidemiology is reviewed

Silvanidae is a small group of cucujoid beetles, and their fossil record is poorly documented. The two recently described genera from Burmese amber, Cretoliota Liu et al. and Protoliota Liu et al. , are distinctive among all known Silvanidae, displaying markedly long antennae and mandibular horns in males, as found in the extant Uleiota Latreille. Due to the limited sampling of fossil specimens, the morphological variations of male mandibular horns remain a mystery. Here we report six well-preserved specimens of Protoliota with both male and female genitalia exposed from mid-Cretaceous Burmese amber. Our discovery confirms the presence of remarkable sexual dimorphism in Protoliota . Males of Protoliota antennatus Liu et al. display short to very long mandibular horns and much longer antennae. Interesting morphological convergence of the beetles (Silvanidae and Staphylinidae) living under the bark of dead trees is briefly discussed. Our discovery represents the first definitive sexual dimorphism in beetles from Burmese amber.

Acorn barnacles are important model species in researches on intertidal ecology, larval development and biofouling. At present, with the development of mitochondrial genomics, it is helpful to understand the phylogenetic relationship from the mitogenomic level. The complete mitochondrial genome of Chthamalus challengeri was presented. The genome is a circular molecule of 15 358 bp. Compared with other species in Balanomorpha, the non-coding region is longer, while the length of the genes is similar to the other species. The overall A+T content of the mitochondrial genome of C. challengeri is 70.5%. There are variations of initiation and stop codons in the known Balanomorpha mitochondrial genomes. The C. challengeri and C. antennatus within the same genus share the identical gene arrangement. However, the gene arrangement of different genera in Chthamalidae is different, as there is a translocation between two tRNA genes and an inversion involving a large gene block. In particular, both srRNA and lrRNA of the two species in Chthamalus are encoded in the heavy strand, differing from the former Balanomorpha species. The topology and gene arrangement in Chthamalidae support each other. Phylogenetic analysis indicates that the Chthamalidae is monophyletic, while the Balanidae and Archaeobalanidae are polyphyletic.

The first Cretaceous taxa of Brontini, Cretoliota cornutus gen. et sp. nov. and Protoliota antennatus gen. et sp. nov. are described from the Burmese amber, representing the oldest fossil records of the family Silvanidae. Pleuroceratos burmiticus Poinar and Kirejtshuk, 2008 originally placed in Silvanidae is removed from this family to Cucujoidea, family uncertain. The discovery of a diverse fauna of Brontini in the Upper Cretaceous sheds a new light on the early evolution of Silvanidae and superfamily Cucujoidea.

The degree of contact of the vector and the vertebrate host is an important variable in determining the vectorial capacity of mosquito species for the arthropod-borne disease. This study conducted in Monufia Governorate, Egypt, to describe the mosquito community composition and species-specific host-feeding patterns. Mosquitoes were surveyed over a 2-years period and their host-feeding patterns were determined in relation to species relative abundance by polymerase chain reaction (PCR).This diagnostic technique was used to identify mammalian blood meals from female mosquitoes by sized DNA fragments following agarose gel electrophoresis. One universal reverse primer and five animal-specific forward primers included Human, Pig, Cow, Dog and Goat were used. Multiple blood meals from distinctive mammalian hosts were identified from single mosquito abdomens. Ninety-nine mosquito blood meals from four mosquito species were identified, 67.7% (67) were mixed blood. Both Cx. pipiens and Cx. antennatus fed on human and animals but feeding strategies differed from outdoors to indoors. Inside houses engorged female Cx. pipiens accounted for (94) 74% of collections and out of this, 53.8% fed on humans as single blood and 40% as mixed blood. However, outdoor, collected Ochlerotatus caspius constituted 7.1% of the collected females. Results suggested that, Cx. pipiens an important bridge of disease vector to humans in Egypt.

Montiphylax, a new genus within the Limnephilidae, is proposed to includePhilocascaalba,P.antennata, andP.thor. Characters for the adults and larvae are presented to separateMontiphylaxfromPhilocasca. A summary of the distribution and life history of theMontiphylaxspecies is provided. A key to ease separation of the known North American caddisfly larvae with gill clusters of single filaments is given.

Continuous monitoring of vector species composition, abundance, dynamics, biting and resting habits is the base to determine the local vector species that affect disease transmission patterns and consequently the choice of cost-effective vector control options. For targeting that, adult mosquito surveys were conducted in Monufia as a representative of the Egyptian governorates in Nile-Delta (Spring 2016– Winter 2018). Totally, 4 species were reported in the selected villages: Culex (Culex) pipiens Linnaeus, Cx. (Cx.) perexiguus Theobald, Cx. (Cx.) antennatus Becker and Ochlerotatus (Ochlerotatus) caspius Pallas. Culex pipiens was the predominant species in all study regions. For each species, the following were examined: the relation of adult indoor and outdoor density with temperature and relative humidity as well as its indoor and outdoor resting density and its relation with temperature and relative humidity, determination of the endophagic and exophagic indices for mosquito biting reference and the seasonal changes in parity status.

Five Chinese species of click-beetles of the genus Gamepenthes Fleutiaux, 1928 are discussed, i.e., G. antennatus (Miwa, 1934); G. holzschuhiSchimmel, 2003; G. hubeiensisSchimmel, 2003; G. jiangxiensisi Schimmel, 2004 and G. montivagus (Miwa, 1929). Two new species, G. clavator Liu & Jiang, sp. n. and G. cuneus Liu & Jiang, sp. n., are described from southern China. Gamapenthes versipellis is removed from the fauna of the Elateridae of China because the records were based on misidentifications. A preliminary key to the species of Gamepenthes in China and a distribution map of the Chinese species of the genus are provided.

Despite the importance of Culex species as major vectors of Rift Valley fever virus, West Nile virus and the microfilariae that cause lymphatic filariasis, information on these mosquitoes in Sudan is limited to works published 65 years ago in the former Anglo-Egyptian Sudan, where some species were only recorded from areas of the territory now known as South Sudan. In this paper, we provide updated information on Culex mosquitoes collected indoors during surveillance studies conducted along the Nile River in central and northern areas of Sudan between 2012 and 2019. Of 3,411 female mosquitoes collected in Khartoum and northern states along the river, 2,560 (75%) were specimens of Culex belonging to 12 species: Cx. (Culex) antennatus (Becker, 1903), Cx. (Cux.) laticinctus Edwards, 1913, Cx. (Cux.) neavei Theobald, 1906, Cx. (Cux.) pipiens Linnaeus, 1758, Cx. (Cux.) perexiguus Theobald, 1903, Cx. (Cux.) poicilipes (Theobald, 1903), Cx. (Cux.) quinquefasciatus Say, 1823, Cx. (Cux.) simpsoni Theobald, 1905, Cx. (Cux.) sinaiticus Kirkpatrick, 1925, Cx. (Cux.) theileri Theobald, 1903, Cx. (Cux.) tritaeniorhynchus Giles, 1901 and Cx. (Culiciomyia) macfiei Edwards, 1923. This is the first record for Cx. tritaeniorhynchus and Cx. macfiei in central Sudan. The relative abundance of each species varied in different areas and seasons, but Cx. antennatus and Cx. quinquefasciatus were the most abundant indoor resting species. We provide an updated dichotomous key for the identification of the adults of Culex mosquitoes known to occur in the Republic of the Sudan.

Simple Summary The mid-Cretaceous amber of Myanmar (also known as Burmese amber) is almost 100 MYA old and represents an invaluable source of information about the evolution of life in the late Mesozoic. This is particularly true for the early flies (lower Diptera) which underwent rapid radiation during the Cretaceous period. Here we describe a remarkable nematocerous fossil fly which shows a character typical of the flies of the suborder Brachycera—with strongly modified antenna—representing new evidence that such a Brachycera-like modification of the antennae has evolved several times during the evolutionary history of Diptera. Abstract A new fossil genus of Bibionidae (Diptera: Bibionomorpha), Burmahesperinus gen. nov., from the mid-Cretaceous Burmese amber, is described and illustrated (type species Burmahesperinus antennatus sp. nov., the other two species included are B. conicus sp. nov. and B. pedicellatus sp. nov.). The new genus is tentatively placed in a new subfamily, Burmahesperininae subfam. nov. of the family Bibionidae. Its possible phylogenetic position is briefly discussed. The new genus, as well as the subfamily, possesses the wing venation similar to the recent genus Hesperinus Walker, 1848, in combination with Brachycera-like modification of both the male and female antenna and the overall habitus typical of fungus gnats (Sciaroidea).

The population biology of the deep-sea shrimp Aristeus antennatus, as with other exploited demersal species, is usually studied using data from fishery statistics. Such statistical analyses have shown female-biased sex ratios during the spawning season in this species. Because the abundance of males increases at greater depths that are not exploited by fisheries (virgin grounds), knowledge on their recruitment is limited. Here, the growth and recruitment of A. antennatus males at fishing grounds was evaluated. This was achieved by integrating information on previously identified breeding behaviours and by tracing the young-of-year cohort through genotyping at 10 microsatellite loci. Using a codend and a codend cover with distinct meshed windows, four groups of males were collected in winter and in a subsequent spawning summer season. Summer collections were mostly composed of pre-adult males, reaching sizes that are to be expected from the growth of winter juveniles, however, many specimens also originated from nearby grounds. This result indicates the horizontal dispersal of male juveniles via intermediate and deep oceanographic currents. Such dispersal complements passive larval dispersal in surface waters, and contributes to the weak genetic divergence among regional fishing grounds. These features could be shared by other deep-sea crustacean and fish species, and should be considered for the sustainable exploitation of demersal fisheries.

12 pages, 8 figures, 2 tables, supplementary data https://doi.org/10.1016/j.jmarsys.2021.103611, The deep-sea blue and red shrimp Aristeus antennatus is a valuable fishing resource in the Northwestern Mediterranean Sea, currently under a local co-management plan in the port of Palamós (Spain). The management measures, although effective, might benefit other ports due to the dispersal patterns of the species pelagic larvae. Gathering information about A. antennatus larval distribution is a key step to describe these patterns, towards the establishment of well-dimensioned management measures. After a first detection of its larvae as the dominant species in the decapod community in Blanes submarine canyon, this broader approach tackles the entire management area along the Eastern Spanish Mediterranean coast (Geographic Subarea 6; GSA 6). Zooplankton sampling was carried out at 101 stations in surface waters (0.5–1 m) and in 8 stations in stratified vertical sampling (0–1200 m) during July–August 2016. Over 6500 A. antennatus larvae of all known stages were found, the first protozoea (PZ I) representing over 95% of the total. This is the first study taking into account the vertical migration of A. antennatus larvae, and we observed a broad distribution of PZ I throughout the water column. Plankton observations of the species larval distribution were supported by an Individual-Based Model suggesting aggregations in the northern submarine canyons, influenced by cold waters from the Northern Current and the geomorphology of the Ibiza Channel. The present study proposes a division of the GSA 6 in three zones to improve fishery management measures, This research was carried out within project CONECTA, funded by the Spanish Ministerio de Economía y Competitividad (MINECO) [grant number CTM2014-54648-C2].

Este artículo contiene 10 páginas, 7 figuras, 2 tablas., The deep-sea red and blue shrimp Aristeus antennatus is a commercially valuable species that occurs in the northwestern Mediterranean Sea where ripe females have been found in fishing areas. In the Palam´os harbor, a local management plan restricts fishing in certain locations to sustain the resource. However, little is known about the dispersal of larvae; specifically, it is not known how far larvae are transported from spawning locations and if there could be mixing of larvae between different fishing areas. The objective of this study was to estimate the spawning sites of larvae collected at 35 sampling stations, evaluate uncertainty in the estimates, and determine if larvae could be exchanged between fishing areas. The spawning sites of larvae were estimated by backward simulation of larval trajectories using a 3-dimensional coupled hydrodynamic and Lagrangian transport model. The backtracked larvae were assigned temperature-dependent stage durations based on a literature review of similar species. Results of model simulations indicated that the median distances from sampling to spawning locations were 11 and 38 km when shortest and longest pelagic durations (PD) were implemented, respectively. Sensitivity studies of backward trajectories showed that distance estimates could vary by as much as 27, 3, and 8 km due to differences in simulated PD, sub-grid-scale turbulence, and advection, respectively. Larvae from 13 of the 35 sampling stations were tracked back to multiple fishing grounds, suggesting that mixing of larvae from different fishing areas could occur. For example, for the sampling stations within the restricted area of Palam´os, 35% of simulated larvae came from the restricted area itself, and 0.9% and 10% of larvae came from neighboring areas to the north and south, respectively. These results suggest that larval transport may connect subpopulations of A. antennatus across different fishing areas, an idea that may help inform regional management plans., Funding was provided through the CONECTA project (CTM2014-54648- C2-1-R) supported by the Ministerio de Economia, Industria y Competividad from Spain government.

Este artículo contiene 10 páginas, 7 figuras., Marine fronts are oceanographic drivers for marine species dispersal, especially for their pelagic organisms like the larvae. Larvae can aggregate at the front and consequently have a limited dispersal, which in turn reduces the connectivity between marine populations. Due to the high variations in the ocean, the fronts also have annual changes (i.e., its formation period, gradient, and position), which have poorly-documented effects on larval retention. In the northwestern Mediterranean Sea, a surface density front is localized across a continental margin which is also indented by submarine canyons. There, an abundant population of the commercial deep-sea blue and red shrimp Aristeus antennatus (Crustacea: Decapoda: Dendrobranchiata: Aristeidae) inhabits the seafloor. Each summer, the shrimp offspring are released in pelagic deep-sea and access the superficial waters divided by the density front. In this study, we focused on the interannual variability of the density front influence on the larval transport of shrimps and its repercussions on the potential connectivity between shrimp populations at each front side. A particle-tracking model simulated the larval transport of A. antennatus in hydrodynamics of the northwestern Mediterranean Sea between the years 2006 and 2016. Larval drift distance and seawater density were correlated by 98%. Over the years 2006–2016, the front region retained 86% of larvae, but this rate yearly varied due to changes in density gradient and position of the front. For example, in 2010, 48% of larvae connected to zones south of the front when the density gradient was relatively low. In 2015, 99.2% of larvae were retained in the front region when the latitudinal front position and density gradient were relatively high. Interannual variability of the front position was potentially related to the strength and position of mesoscale circulation patterns. Our findings suggest that the larval retention on habitats favored by canyon productivity because of the front could explain the persistent abundance of A. antennatus population. This information is important to set or improve the fisheries management in zones with strong interannual hydrodynamic variability., Fundings were provided through the CONECTA’s project supported by the Ministerio de Economia, Industria y Competividad from Spain Government.

Temporal variability of the genetic structure and connectivity patterns of the blue and red shrimp Aristeus antennatus in the seven most important fishing grounds of the Western Mediterranean Sea, were assessed using twelve microsatellite loci during 2 consecutive years (2016 and 2017), in a total of 1403 adult individuals. A high level of geographical connectivity among groups was observed in the two studied years. In fact, no significant geographical differentiation was found in 2016 (FST = 0.0018, p > 0.05), whereas it was indicated in 2017 (FST = 0.0025, p FCT = 0.0006, p A. antennatus.

10 pages, 3 figures, 2 tables, Accurate information on commercial marine species larvae is key to fisheries science, as their correct identification is the first step towards studying the species’ connectivity patterns. In this study, we provide a complete morphological description of the first protozoeal stage of the valued deep-sea blue and red shrimp Aristeus antennatus and of the small mesopelagic shrimp Gennadas elegans. These two larval morphologies previously posed a risk of misidentification, thus hindering the study of A. antennatus larval ecology and dynamics in the context of fisheries science. Using specimens caught in the plankton at various locations in the Northwestern Mediterranean Sea and identification confirmed by molecular methods, the larvae of A. antennatus and G. elegans are distinguished from each other by the ornamentation of the antennula. A possible confusion in previous descriptions of Aristeidae larvae is addressed and a new key for the identification of Dendrobranchiata larvae provided, This research was carried out within project CONECTA (CTM2014-54648-C2) funded by the Spanish Ministerio de Economía y Competitividad (MINECO).The authors would like to thank Dr. A.

A new species of Sarmydus Pascoe, 1867, S. bagh sp. nov., is described from north India and adjacent countries based on the habitus of both male and female, and male genitalia characters. Detailed taxonomic investigations reveal previous misidentification of several specimens from India of the new species as S. antennatus Pascoe, 1867. Accordingly, Sarmydus antennatus Pascoe, 1867 is removed from the Indian fauna. Photographs of the holotype of S. antennatus are provided, and the characters of this species discussed in detail. DNA barcoding analysis of the Himalayan Sarmydus species has been done for the confirmation of the new species. This analysis depicts significant genetic divergences of >14% between S. bagh sp. nov. and its congeners, thus, sufficiently supporting morphological interpretations.

Two species of Sabidius Strelzov, 1973 were collected during a benthic survey, from 10-3,000 m deep, in Espírito Santo Basin, off southeastern Brazilian coast. Those species are S. cornatus (Hartman, 1965) and S. antennatus sp. nov. The genus Sabidius was monotypic until the present study, in which a new species is proposed, together with a redescription of the type species, with expansion of the geographic distribution of the genus and of the type species. The diagnostic feature of the genus is the morphology of prostomium, with crested anterior margin. The main feature that differentiates the two species within the genus is the presence/absence of a median antenna, which is present in the new species described in the present study and absent in Sabidius cornatus.

The present study evaluated the repellent activity of hexane, chloroform, methanol and ethyl acetate extracts from Deverra triradiata aerial parts against three mosquito species (Anopheles sergentii, Culex pipiens and Culex antennatus). At 3.33, 1.67, 0.83 & 0.42 mg/cm2, all tested extracts showed a variable degree of repellency against tested mosquito species depending on solvent used in extraction. The highest repellent activity attained by hexane extract, with RD50 equal to 0.704, 1.122 & 0.92 mg/cm2 against An. sergentii, Cx. pipiens and Cx. antennatus starved females, followed by ethyl acetate (0.904, 1.323 & 0.9 mg/cm2), chloroform (1.101, 1.367 & 1.157 mg/cm2) and methanol (1.183, 1.578 & 1.323 mg/cm2) extracts. Also, RD90 of hexane, chloroform, methanol and ethyl acetate extracts recorded 2.567, 2.92, 3.067 and 2.88 mg/cm2 against An. sergentii, 3.027, 3.317, 3.593 & 3.547mg/cm2 against Cx. pipiens, 2.703, 3.09, 3.267 & 2.81mg/cm2 against Cx. antennatus starved females, respectively. In addition, complete repellency time was varied according to solvent used in extraction. D. triradiata tested extracts showed a strong biting deterrency against tested mosquito species, where the highest complete repellency time (187.7min) a achieved by methanol extract againstAn. sergentii starved females at 3.33 mg/cm2 and the lowest complete repellency time (57.7min) recorded by hexane extract against Cx. pipiens bites at 0.42 mg/cm2, respectively.

The present study evaluated the effect of different blood meal sources (human volunteer, pigeon, guinea pig and Egyptian mastigure) on feeding rate and reproductive performance of laboratory colonizedCulex pipiens L., Anopheles sergentii Theobald and Culex antennatus Becker mosquitoes during two sequential gonotrophic cycles. The obtained results showed that, mosquitoes tested exhibited a special feeding rate to human blood, as the mosquitoes fed on human blood exhibited higher feeding, fecundity and fertility rates than those fed on either type of blood sources. Concerning with feeding rates, the highest percentages of engorged females during a first blood meal (82.3, 88.1 and 86.3) were recorded when Cx. pipiens, An. sergentii and Cx. antennatus females fed on the pigeon and human hosts. Meanwhile, the highest percentages of engorged females during second blood meal (88.4, 93.5 and 92.7) occurred when Cx. pipiens, An. sergentii and Cx. antennatus females fed on the human host, respectively. Also, fecundity and fertility rates of mosquitos fed on different hosts were varied between gonotrophic cycles, as at the first gonotrophic cycle fecundity and fertility of tested mosquitoes were greater than those at the second gonotrophic cycle. In addition, feeding on human blood recorded higher fecundity and fertility rates in tested mosquito species as compared with feeding on other hosts.

Different watercourses act as breeding habitats for mosquito larvae, thus responsible for the spread of certain diseases. This study examined the effect of certain physico-chemical parameters (temperature, turbidity, pH and salinity) on the population dynamics of mosquito larvae dispersed in the infected regions by filariasis in Alkorin village, Sharkia, Egypt during 2015 and 2016. Larval density index (LDI) was used to examine the population dynamics of mosquito larvae distributed in the studied areas (27 sites in 6 watercourses). During the study, LDI of Culex pipiens pipiens was the highest percentage (76.4%). Meanwhile, LDI for other mosquito larval species were (12%, 7%, 3%, 1% and 0.6%) for (Cx. antennatus, Cx. perexigus, Cx. pusillus, Cx. univittatus and Cx. sinaiticus), respectively. The maximum rate of LDI for Cx. pipiens larvae was observed in autumn 2015 at all the sampling sites and a significant positive correlation of temperature and turbidity with the larval population (P 0.05) on the larval distributions of different species.The present data may be concluded that the high LDI of Cx. pipiens is an interpretation for the transmission of filarial diseases in Alkorin village, Sharkia, Egypt.

Culex antennatus (Diptera: Culicidae), Anopheles coustani (Diptera: Culicidae) and Anopheles squamosus/cydippis were found to be infected with Rift Valley fever virus (RVFV) during an epidemic that occurred in 2008 and 2009 in Madagascar. To understand the roles played by Cx. antennatus and An. coustani in virus maintenance and transmission, RVFV vector competence was assessed in each species. Mosquito body parts and saliva of mosquitoes that fed on RVFV-infected blood were tested for RVFV using real-time quantitative polymerase chain reaction (RT-qPCR) assays. Overall, viral RNA was detected in body parts and saliva at 5 days post-infection (d.p.i.) in both species. At 5 d.p.i., infection rates were 12.5% (3/24) and 15.8% (6/38), disseminated infection rates were 100% (3/3) and 100% (6/6), transmission rates were 33.3% (1/3) and 83.3% (5/6), and transmission efficiencies were 4.2% (1/24) and 13.2% (5/38) in Cx. antennatus and An. coustani, respectively. Although RVFV detected in saliva did not propagate on to Vero cells, these results support potential roles for these two mosquito species in the transmission of RVFV.

The crucial step of most of the current genetic studies is the extraction of DNA of sufficient quantity and quality. Several genomic DNA isolation methods have been described to successfully obtain male DNA from shrimp species. However, all current protocols require invasive handling methods with males for DNA isolation. Using Aristeus antennatus as a model we tested a reliable non‐invasive differential DNA extraction method to male DNA isolation from spermatophores attached to female thelycum. The present protocol provides high quality and quantity DNA for polymerase chain reaction amplification and male genotyping. This new approach could be useful to experimental shrimp culture to select sires with relevant genetic patterns for selective breeding programs. More importantly, it can be applied to identify the mating pairs and male structure in wild populations of species as A. antennatus, where males are often difficult to capture. Our method could be also valuable for biological studies on other spermatophore‐using species, such as myriapods, arachnids and insect This work was supported by a grant from Spanish Ministerio de Economía y Competitividad (CTM2014-54648-C2-2-R) to MIR.

The subfossil remains of 14 cimicids (Hemiptera: Cimicidae) were recovered during archaeological investigations of the Paisley Five Mile Point Cave site (35LK3400), an exceptionally well-dated (n = 229 radiocarbon dates) late Pleistocene-early Holocene rock shelter site in south-central Oregon. Nine of the specimens have been assigned to three modern species of Nearctic Cimicidae-Cimex antennatus Usinger & Ueshima, Cimex latipennis Usinger & Ueshima, and Cimex pilosellus (Horvath)-whereas the remaining five individuals were too fragmentary to positively identify. The chronology of the insect assemblage puts one specimen at circa 5,100 calibrated years before present (cal. yr BP), and the remaining 13 range in age from 9,400 to almost 11,000 cal. yr BP. Although fossil and subfossil cimicid remains have been recovered at other archaeological sites, the fossil record for bed bugs is largely undocumented. The Paisley Caves specimens thus far represent the oldest remains of the genus in probable contact with humans on record.

Understanding life history variation and strategies is crucial for stock assessment and fisheries management due to the direct effects on population dynamics, effective population size, sex-ratios, levels of inbreeding, and relatedness among individuals. Aristeus antennatus (En ─ Blue and red shrimp; Fr ─ Crevette rouge; Sp ─ Gamba rosada) is one of the most exploited demersal resources in the Western Mediterranean Sea. However, information regarding the mating system and mate choice preferences remains largely unknown. Advances in molecular genetic markers and methods of inferring biological relationships among individuals have facilitated new insights into the reproductive dynamics of the species in the wild. Here, we used microsatellite markers to examine the A. antennatus mating system and putative mate choice preferences. Our results provided clear evidence of polyandry and polygyny. Relatedness analyses, together with FST and DAPC values showed females exhibited a mating bias towards unrelated males. Mating males were inferred from spermatophores and suggested males were sympatric with females and were also from other spawning grounds. Our findings provided the first description of the reproductive behavior of blue and red shrimp This work was supported by a grant from Spanish Ministerio de Economia y Competitividad (CTM2014-54648-C2-2-R) to MIR.

A large collection of mesoparasitic copepods from polychaete hosts collected in northern European waters was examined. The term mesoparasitic refers to highly transformed copepods where the adult female attaches by embedding part of its body in the host. Representatives of five known familes were found and a new family is established. A single new species, Bradophila minuta sp. nov., was described in the family Bradophilidae. It occurred exclusively on the flabelligerid Diplocirus glaucus (Malmgren, 1867). Two genera of the family Herpyllobiidae were represented: Herpyllobius Steenstrup & Lütken, 1861 and Eurysilenium M. Sars, 1870. Herpyllobius arcticus Steenstrup & Lütken, 1861 was found on at least five different polynoid hosts, two of which, Harmothoe fragilis Moore, 1910 and Antinoe sp., were new host records. A new species, H. cluthensis sp. nov. was described from Malmgrenia species in Scottish waters. The large species, Herpyllobius cordiformis Lützen, 1964, was collected in Arctic waters from Eunoe cf. oerstedi. It is the first report of this parasite in Europe. The common parasite H. polynoes (Krøyer, 1864) was found on six different polynoid hosts, three of which, Harmothoe bifera, Malmgreniella mcintoshi Tebble & Chambers, 1982 and Eunoe ?barbata are new host records. Eurysilenium truncatum M. Sars, 1870 was collected from Eucranta villosa Malmgren, 1866, Eunone sp., and Gattyana cirrhosa (Pallas, 1766). The material from Eucranta villosa caught at 72.6ºN comprises both a new host record and is the most northerly report of this parasite. Specimens of Eurysilenium which differed from E. truncatum in a number of features were found on Harmothoe fragilis and H. impar (Johnston, 1839). A new family, the Pholoicolidae, is established to accommodate Pholicola chambersae gen. et sp. nov., parasitic on Pholoe pallida Chambers, 1985. The family Phyllodicolidae was represented by all three of its known species: Phyllodicola petiti (Delamare Deboutteville & Laubier, 1960), Cyclorhiza eteonicola Heegaard, 1942 and C. megalova Gotto & Leahy, 1988. The former was found on Eumida ockelmanni Eibye-Jacobsen, 1987, a new host record. A single ovigerous female of C. eteonicola was collected from a new host, Eteone spetsbergensis Malmgren, 1865. Cyclorhiza megalova was common on Eteone longa (Fabricius, 1780) and E. longa/flava complex. A rich diversity of members of the family Saccopsidae was found, including three known species of Melinnacheres M. Sars, 1870 plus nine new species placed in four new genera. Melinnacheres was represented by M. ergasiloides M. Sars, 1870, M. steenstrupi Bresciani & Lützen, 1961 and M. terebellidis Levinsen, 1878. Melinnacheres ergasiloides was found on Melinna elizabethae McIntosh, 1914, M. steenstrupi on members of the Terebellides stroemi-complex and T. atlantis Williams, 1984, while M. terebellidis was found on the T. stroemi-complex and on T. shetlandica Parapar, Moreira & O'Reilly, 2016. A new genus, Trichobranchicola gen. nov., was established to accommodate T. antennatus gen. et sp. nov., a parasite of Trichobranchus sikorskii Leontovich & Jirkov in Jirkov, 2001, T. glacialis Malmgren, 1866 and Trichobranchus sp. The second new genus, Lanassicola gen. nov., was established to accommodate the type species, Lanassicola arcticus gen. et sp. nov. parasitic on Lanassa venusta (Malm, 1874), plus two additional species, L. bilobatus gen. et sp. nov. on Lanassa nordenskjoeldi Malmgren, 1866, and L. dorsilobatus gen. et sp. nov. on Proclea graffii (Langerhans, 1884). A new subfamily, Euchonicolinae, was established within the Saccopsidae to accommodate two new genera, Euchonicola gen. nov. and Euchonicoloides gen. nov. The type species of Euchonicola gen. nov. is E. caudatus gen. et sp. nov., a parasite of Euchone sp., and it includes two other species, E. linearis gen. et sp. nov. on Chone sp., and E. parvus gen. et sp. nov. on Euchone sp. The type species of Euchonicoloides gen. nov. is E. elongatus gen. et sp. nov. found on a host belonging to the genus Euchone, and it also includes Euchonicoloides halli gen. et sp. nov. from Jasmineira caudata Langerhans, 1880. Four species of the family Xenocoelomidae were found: Xenocoeloma alleni (Brumpt, 1897), X. brumpti Caullery & Mesnil, 1915, X. orbicularis sp. nov. and Aphanodomus terebellae (Levinsen, 1878). Xenocoeloma alleni was found on four different species of Polycirrus and on Amaeana trilobata (M. Sars, 1863) and X. brumpti was found on Polycirrus norvegicus Wollebaek, 1912. Xenocoeloma orbicularis sp. nov. occurred only on Paramphitrite birulai (Ssolowiew, 1899). Aphanodomus terebellae was found on three hosts, only one of which, Leaena abranchiata was new.

Salivary glands of mosquitoes play an important role in food ingestion and digestion as well as transmission of pathogens. Mosquitoes are able to adapt to feed on blood by salivary glands which secrete proteins that work against the haemostasis process. So, the identification of these protein contents in the salivary glands of Culex antennatus (males and females) is the aim of this study. In the present study, protein banding pattern (Native and SDS PAGE) of salivary glands of adult Culex antennatus (un-fed, sugar-fed, starved and blood-fed) was investigated. Males and females of Cx. antennatus were dissected and their salivary glands were collected at un-fed stage, 0-, 3-, 6-, 12- and 24- h after sugar feeding and starved stage. Female salivary glands were additionally collected at different stages of blood feeding (probing time, partial engorgement, full engorgement, 3-, 6-, 12-, 24-, 48- and 72- h. after blood meal and after oviposition. Results of native-PAGE demonstrated that there were differences in the overall protein banding pattern in salivary glands of males and females of Cx. antennatus in the cases of un-fed, sugar-fed and starved stages. Differences in salivary gland proteins were observed when comparing males of all stages, too. Differences in salivary gland proteins were also noticed when comparing females of all stages. Furthermore, all blood-feeding stages of females showed differences in salivary gland proteins when compared to sugar-fed and starved females. Results of SDS-PAGE clarified that the molecular weight of the separated proteins (in all stages) ranged from 317.36 to 10.91 KDa. Differences were also observed between males and females in the cases of un-fed, sugar-fed and starved stages of Cx. antennatus.

During three surveys between September 2009 and June 2011, a total of 20867 specimens of A. antennatus were caught from the 127 successful hauls with a total towing time of 219.5 h. Carapace length ranged between 12-61 mm for females (mean length, 35.8±8.2 mm) and 14-35 mm for males (24.8±3.4 mm). The two-way MANOVA shoved that depth had a significant effect on the abundance (p < 0.05) and biomass (p < 0.01) indices. However, season showed an insignificantly effect on both indices. The highest values of abundance and biomass were obtained in the depth stratum of 500 m. There was a statistically significant difference in the overall sex ratio from the expected 1:1 (p < 0.05). The highest percentages of mature adult females (carapace length > 27 mm) were recorded in June, July and August. The monthly gonadosomatic index of A. antennatus females changed seasonally, reaching a maximum value between July and August. The length-weight relationships in female and male specimens exhibited a strong negative allometry. The monthly length-frequency distributions showed that females of A. antennatus exhibited a maximum of six modal size groups per year. The recruitment of young-of-the-year took place mainly between January-April. The fishing mortality, reference point (F0.1) of fisheries mortality and exploitation rate were 0.498 year-1, 0.444 year-1 and 0.524 year-1, respectively. The fishery activity and the biological aspects of A. antennatus in the Antalya Bay have a lot of common and non-common points with other areas of the Mediterranean Sea. The above-men-tioned differences could be attributed to the different oceanographic and environmental parameters in the present study area. Se realizaron tres campañas de muestreo entre septiembre de 2009 y Junio de 2011 en el golfo de Antalya. En ellas se capturaron un total de 20867 ejemplares de A. antennatus a partir de 127 lances efectivos realizados en un total de 219.5 h. La longitud del caparazón de las hembras se mantuvo en un rango de 12-61 mm (media 35.8±8.2 mm), mientras que en los machos fue de 14-35 mm (media, 24.8±3.4 mm). La significación estadística entre la profundidad y los índices de abundancia y biomasa se testaron mediante una ANOVA de doble vía (p < 0.05 y p < 0.01, respectivamente); sin embargo, la estacionalidad no fue significativa para los mismos índices (p < 0.05). Los mayores porcentajes de hembras maduras (CL > 27 mm) se registraron entre junio y agosto; meses en los cuales también se observaron los máximos índices gonadosomáticos de estas hembras. En ambos sexos la relación talla-peso presentó una fuerte alometría negativa. La distribución de frecuencias de tallas mensuales señaló para las hembras seis modas por año. El reclutamiento anual se detectó entre enero y abril. La mortalidad por pesca y la tasa de explotación fueron de 0.498 año-1, 0.444 año-1 y 0.524 año-1, respectivamente para los tres períodos de muestreo. En el bahía de Antalya la actividad pesquera y los aspectos fundamentales de la biología de A. antennatus presentan una alta similitud con resultados obtenidos de otras poblaciones del Mediterráneo Central y Occidental. Las pocas diferencias que se destacan se atribuyen a las particulares condiciones oceanográficas y ambientales del área de estudio.

Two species of isopods of the family Idoteidae were collected in the same sample, among sea grasses, in the northern Gulf of California, Mexico. The first species, Synidotea harfordi Benedict, 1897, was more abundant (46 specimens) than the second species, Eusymmerus antennatus Richardson, 1899 (eight specimens). Synidotea harfordi has previously been considered uncommon in the Gulf of California, and more like a component of warm-temperate to colder-water fauna. The male of E. antennatus has not been illustrated but SEM photographs are provided and show angular margins of the first three pereonites and a sharply bent lateral margin of the telson. Females also have angular first pereonites. All previous illustrations show rounded pereonites margins. Buccal appendages of E. antennatus are illustrated and compared with previous descriptions.

9 pages, 5 figures, 4 tables, Microplastic (MP) ingestion has been reported in a wide variety of organisms, however, its spatial occurrence and effects on wild populations remain quite unknown. The present study targets an economically and ecologically key species in the Mediterranean Sea, the shrimp Aristeus antennatus. 39.2% of the individuals sampled had MP in their stomachs, albeit in areas close to Barcelona city the percentage reached values of 100%. Overall, MP ingestion was confirmed in a wide spatial and depth (630–1870 m) range, pointing out the great dispersion of this pollutant. The benthophagous diet and close relationship with the sea bottom of A. antennatus might enhance MP exposure and ultimately lead to accidental ingestion. Detailed analysis of shrimps’ diet revealed that individuals with MP had a higher presence of endobenthic prey. Microplastic fibers are probably retained for long periods due to stomach's morphology, but no negative effects on shrimp's biological condition were observed, This study was supported by the Spanish Ministry of Science and Innovation (MICINN) projects “BIOMARE” (CTM2006-13508-C02-01MAR) and “ANTROMARE” (CTM2009-12214-C02-01/02).

Carrion beetles (Coleoptera: Silphidae) provide a valuable ecosystem service by promoting nutrient cycling and controlling pests like noxious flies (Diptera: Calliphoridae and Sarcophagidae). Our main goal was to examine the relationship between the occur - rence of carrion beetles and soil type. We used pitfall traps to collect 43,856 specimens of 15 species of carrion beetles in the Czech Republic during 2009. We found that the abundance of seven of the carrion beetles - Nicrophorus antennatus (Reitter), N. germanicus (Linnaeus), N. humator (Gleditsch), N. interruptus (Stephens), N. sepultor (Charpentier), Silpha obscura obscura (Herbst) and T. sinuatus (Fabricius) - was significantly higher either in areas with chernozem or fluvisol soils. These findings support our hypothesis that soil type could be an important factor determining the occurrence of necrophagous European carrion beetles. Our findings could be helpful when selecting important nature conservation sites (particularly inasmuch as N. antennatus, N. germanicus and N. sepultor are listed as endangered species on the Czech Red List of Invertebrates) as in this respect localities where there are chernozem soils are potentially valuable.

Fossil Scydmaeninae beetles are exceptionally poorly known and those described usually lack important details to reliably analyze their phylogenetic relationships with extant taxa. Baltostigus n. gen. is the first extinct ant-like stone beetle taxon unambiguously assigned to the tribe Mastigini. It includes B. antennatus n. sp. (the type species of Baltostigus) and B. horribilis n. sp., from the lower to middle Eocene amber of Poland and Lithuania, respectively. Results of a phylogenetic analysis comprising morphological characters of all extant and extinct genera of the supertribe Mastigitae strongly support the placement of Baltostigus as a sister group to all remaining Mastigini. The new genus shows character states not known in any extant Mastigini: fully developed hind wings, prominent humeral calli, deep elytral punctures partly arranged in longitudinal rows and symmetrical aedeagal parameres. These features suggest that Mastigini might have evolved from forms morphologically similar to small-bodied extant Clidicini of the ‘Leptochromus lineage.’

13 pages, 2 figures, 4 tables, Stable isotope analysis (SIA) of carbon and nitrogen is now a common tool to investigate trophic relationships and food-web structure in aquatic ecosystems. However, species-specific and tissue-specific lipid content sometimes hinders the correct interpretation of δC and δN values because lipids are C-depleted with respect to proteins, and thus tissue lipid extraction is generally invoked. We assessed the effects of lipid extraction on δC and δN compositions and C:N ratios of muscle, liver (or hepatopancreas) and gonads of three common Mediterranean deep-sea species with different locomotory activity, buoyancy mechanisms and feeding modes: the benthic-feeder shrimp Aristeus antennatus, the nektobenthic-feeder shark Galeus melastomus and the pelagic-feeder fish Micromesistius poutassou to evaluate both the effect of lipid extraction on SIA data and the validity of δC lipid correction models. Results showed that the effect of lipid extraction is not unique but some common patterns can be identified. Lipid extraction resulted in increased δN values in the liver and the muscle and in decreased δN values in the gonads, in increased δC values in all the tissues of the three species, except in the hepatopancreas of A. antennatus, and in decreased C:N ratios. The magnitude of the changes was species- and tissue-specific. We assessed the validity of δC correction equations for lipid content in muscle and liver tissues available from literature in the species from this study. Such equations provided corrected δC values equivalent to those obtained through lipid extraction when applied to a species with similar characteristics (i.e., taxon, behavior, etc.) to those for which the equations were designed. Our results for muscle tissue showed that not one of the equations tested was valid for the deep-sea shark G. melastomus, and we propose a species-specific model with a fairly feasible model efficiency. Besides, tissue-specific equations for liver in G. melastomus provided non-significant differences between δC and δC values, but all model efficiencies were fairly low. Thus, lipid extraction trials on elasmobranch muscle and liver tissue to determine effects on δC and δN values on a species-by-species basis are recommended. Our research together with a comprehensive literature review on this topic, highlights that there is no accepted or mandated standard of treatment for lipids when using stable isotope analyses, The authors acknowledge funding from Spain's National Research Programme for research project BIOMARE (CTM2006–13508-CO2–02/MAR) and ANTROMARE (CTM2009–12214-C02–01/MAR) projects

Neacratus antennatus Mantilleri, Lanuza-Garay, and Bartolozzi, new species, a straight-snout weevil from Central America, is described and illustrated. Although the new taxon shows very peculiar antennal and elytral apices, it is provisionally included in the genus Neacratus Alonso-Zarazaga, Lyal, Bartolozzi, and Sforzi, 1999. The new species is compared with other Neacratus species, particularly to Neacratus glabratus (Lund, 1800), the type species of the genus.

A revision of the genus Deretaphrus Newman, 1842 (Coleoptera: Bothrideridae) is presented. Deretaphrus is a predominantly Australian genus (22 species), although single species are also present in New Caledonia, Bolivia, and the Pacific Northwest USA. Members of the genus are large (5–13 mm) and commonly collected. Deretaphrus larvae are ectoparasitic on wood-boring insects and may pose some utility as biological control agents. Approximately 1,900 specimens were borrowed from 44 collections and museums, representing the majority of the world's total holdings.

Special issue Integrated study of a deep submarine canyon and adjacent open slopes in the Western Mediterranean Sea: an essential habitat.-- 11 pages, 4 figures, 3 tables, Due to their geomorphological structure and proximity to the coastline, submarine canyons may act as natural conduit routes for anthropogenic contaminants that are transported from surface waters to the deep-sea. Organisms dwelling in these canyon environments might thus be at risk of experiencing adverse health effects due to higher pollution exposure. To address this question, chemical and biochemical analyses were conducted on two of the most abundant deep-sea fish species in the study area, namely Alepocephalus rostratus and Lepidion lepidion, and the most abundant deep-sea commercial decapod crustacean Aristeus antennatus sampled inside Blanes canyon (BC) and on the adjacent open slope (OS). Persistent organic pollutants (POPs) levels, including polychlorinated biphenyl (PCB), dichlorodiphenyltrichloroethane (DDT) and derivatives, hexachlorocyclohexanes (HCHs) and hexachlorobenzene (HCB) were determined in muscle tissue of selected samples from 900. m and 1500. m depth. Potential effects resulting from contaminant exposure were determined using hepatic biomarkers such as ethoxyresorufin. -O-deethylase (EROD), pentoxyresorufin. -O-deethylase (PROD), catalase (CAT), carboxylesterase (CbE), glutathione-. S-transferase (GST), total glutathione peroxidase (GPX), glutathione reductase (GR) and superoxide-dismutase (SOD) enzyme activities and lipid peroxidation levels (LP). L. lepidion and A. antennatus tissues exhibited higher POP levels inside BC compared to the OS at 900. m depth. These findings were consistent with biomarker data (i.e. enzymatic response to presence of contaminant agents). Elevated xenobiotic-metabolizing (EROD and PROD) and antioxidant enzymes (CAT and GPX) indicated higher contaminant exposure in both species caught within BC. No difference in POP accumulation between sites was observed in L. lepidion at 1500. m depth, nor in biomarker data, suggesting that the pollution gradient was less pronounced at greater depths. This trend was further corroborated by the results obtained for A. rostratus at 1500. m depth. Hence, the present findings suggest the, at least temporary, existence of a pollution gradient between Blanes canyon and the open slope at shallower depths and this resulted in alterations of the physiology of deep-sea organisms dwelling within this area. © 2013 Elsevier Ltd., The present work was funded by the Spanish Science and Technology Ministry Projects PROMETEO (CTM2007-66316-C02-02/MAR to JBC), DOS MARES (CTM2010-21810-C03-03/MAR to JBC), BIOFUN (CTM2007-28739-E/MAR to Francesc Sardà) and HERMIONE Project (EC-FP7 Contract Number 226354).

An illustrated key is provided to the 19 genera of the subfamily Idolothripinae from China, and a checklist given to 62 named species, of which six species are newly recorded from China, together with the genus Bolothrips that is represented by two un-named species. A generic diagnosis is given for each genus, along with some discussion of systematic relationship problems and species diversity. Identification keys to species of 11 genera are provided, and Megathrips antennatus Guo, Feng & Duan is considered as a new synonym of Megathrips lativentris (Heeger).

The blue and red shrimp, Aristeus antennatus, is a commercially important crustacean, in the Mediterranean Sea, which has been listed as a priority species for fishery management. Hypervariable microsatellite markers could be a useful tool to identify genetic stocks among geographically close fishing grounds. Potential microsatellite markers (97) identified from next-generation sequencing of an individual shrimp using a 454 GS Junior Pyrosequencer were tested on a preliminary panel of 15 individuals representing the four worldwide genetic stocks of the species from which 35 polymorphic loci were identified and used to characterize an additional 20 individuals from the Western Mediterranean Sea. In the Western Mediterranean sample, 32 out of 35 were polymorphic loci and the number of alleles per locus ranged from 2 to 14 and expected heterozygosity ranged from 0.050 to 0.968. No linkage disequilibrium was detected, indicating the independence of the loci. These novel microsatellites provide additional tools to address questions relating to genetic diversity, parentage studies and connectivity patterns of A. antennatus populations and help develop effective strategies to ensure long-term sustainability of this resource This work was supported by grants by the Spanish Government (AGL2009-09228 and CTM2014-54648-C2-2-R) and Ajuntament de Palamós, Spain (Beca Coopoerativa La Equitativa 2013–2014) to MIR.
