This paper describes the chemical composition of a fossilized fish of the Cretaceous period, from a 100 million-year-old, material originated from the Araripe Basin (northeastern Brazil). The chemical composition of the fossilized fish was analyzed by means of X-ray powder diffraction and Fourier transform infrared spectroscopy (FT-IR). The spectroscopic study has proven that the main substances found in the fossilized fish are CaCO3 and Ca5(PO4)3(OH). A tentative mechanism to explain the fossilization process is also given.

No. of bitstreams: 0 Previous issue date: 2019-10-26 We evaluated the activity period, thermal ecology, habitats, and preference for microhabitats of the skink Mabuya arajara in a humid forest environment on the slope of the Araripe Plateau, Brazil. A total of 283 lizards were observed. The lizards were found to be diurnally active (unimodal type pattern), with peak activity during the hottest hours of the day (1100 to 1200). About habitat use, the majority of individuals (73.8% N = 209) were recorded in the narrow transitional area, in the edges of the forest; while 26.4% of individuals were observed in open areas and no observations were made in dense forest. Seven different types of microhabitats were used, with fallen palm leaves (Arecaceae) being the preferred (47.7% N = 135). Considering all lizards, microhabitat niche breadth was 3.27. Males and females presented a high overlap (0.95) in microhabitat use. The average Tc recorded for M. arajara was 32.06 ± 2.72°C. Body size (SVL) did not influence body temperature (F = 0.51, P = > 0.05). Most of the animals were observed with their bodies completely exposed (67.84%, N = 192), 18.37% (N = 52) were semi-exposed and 13.79% (N = 39) were in shelters. Among animals with some degree of sunlight exposure, 57.59% (N = 163) were in shadows, 25.10% (N = 71) were under sunlight filtered by vegetation, and 17.31% (N = 49) were under direct sunlight.A review of the ecology of Mabuya spp. shows that several features appear to be conserved among members of the genus.

No. of bitstreams: 0 Previous issue date: 2021-05-01 The matamatas (Chelus fimbriata and the recently described Chelus orinocensis) are the largest species in the family Chelidae, easily identified by their distinct morphological characteristics. The matamatas have a wide distribution in South America, occurring in Bolivia, Brazil, Colombia, Ecuador, Guyana, French Guiana, Peru, and Venezuela, as well as Trinidad and Tobago. However, there are many gaps in the knowledge of its distribution. The objective of this study was to present new records of occurrence for the C. fimbriata species complex and describe the area of distribution. We compiled data from published papers, databases in museums and other scientific collections, and research institutes and conservation organizations. From these data we mapped the species distribution, considering 3 types of river drainages based on water color in the Amazon Basin. We added 182 new records in Brazil, Venezuela, Colombia, Bolivia, and Peru, demonstrating that the C. fimbriata species complex has a wide distribution, totaling 6,907,551 kmacross all 3 river types. Most records were concentrated in areas lower than 200 m above sea level.

No. of bitstreams: 0 Previous issue date: 2021-05-01 The complete larval development of the spider crab Maguimithrax spinosissimus (Lamarck, 1818) is re-described and illustrated in detail from laboratory-reared material the development consisted of the typical pattern reported for the Majoidea, two zoeal stages and one megalopa the complete larval development from hatching to first crab lasted 5-6 days at temperatures that ranged between 24-28 °C. Both zoeal stages of M. spinosissimus exhibited moderate reduction in the number of setae in the maxilla and maxillipeds, from the first to the second zoeal stage, when compared with other closely related species. Maguimithrax spinosissimus can be easily distinguished from other species belonging to the closely related genus Mithrax by the (i) setation of the endopod of the maxillule, maxilla and second maxilliped in both zoeal stages; (ii) setation of the scaphognathite of the maxilla in the first zoeal stage; (iii) setation of the basis of maxilliped I in the second zoeal stage and megalopa; (iv) morphology of the antennule and antenna in the second zoeal stage; and (v) setation of the antennule, coxal endite of maxilla, and exopod of second maxilliped in the megalopa. All these characters support the recent generic status of Maguimithrax within the Mithracidae. Additional morphological details, not available previously, are provided. This study will provide support for conservation strategies in this species.

The description was based on integrative taxonomy approach using DNA sequences from the D1-D3 domains of the 28S rDNA gene. The new species was confirmed through the phylogenetic analysis of the 28S rDNA gene, which showed that Wallinia caririensis n. sp. is a sister taxon of Wallinia brasiliensis (Dias, Müller, Almeida, Silva, Azevedo, Pérez-Ponce de León, and Abdallah, 2018, and Wallinia anindoi Hernández-Mena, Pinacho-Pinacho, García-Varela, Mendonza-Garfias, and Pérez-Ponce de León, 2019), a species which parasitizes Astyanax fasciatus (Cuvier, 1819), A. lacustris (Lucena and Soares, 2016) in Brazil, and A. aeneus (Günther, 1860) in Mexico, with genetic divergences of 2% and 3%, respectively. The new species can be distinguished morphologically from its congeners by possessing large body size (length and width) and tapered extremity in the posterior end of the body, eyespots are present at the pharynx level, and vitelline follicles reach up to the half distance between the posterior testis and the extremity of the body, by having larger testes distributed in coincident zones (i.e., contiguous) and non-operculated eggs (a conspicuous characteristic in W. brasiliensis). To date, species of this genus have already been described in freshwater fishes from Mexico, Costa Rica, Venezuela, and Southeastern Brazil. The species described in this study consists of the second species parasitizing characids in Brazil, and the first record in Northeastern Brazil. This finding fills a gap and expands the biogeographic distribution of the genus Wallinia in South America.

No. of bitstreams: 0 Previous issue date: 2021-01-01 In brachyuran crabs, the complexity of the copulatory system provides important information about the systematics of the group. Here we used scanning electron microscopy and light microscopy to provide information about the morphological changes during the gonopods ontogeny in the spider crab Mithraculus forceps. For this, a series of specimens were analysed and grouped in size classes of cephalothorax width (CW). The smaller males (first and second size classes) presented the first gonopod without a formed ejaculatory aperture and with an indistinct apical plate. The ejaculatory canal aperture is fully formed in size class 5 with 8.8 to 9.9 mm (CW). In adult males, the apical plate is divided in two lobes: a rounded mesial lobe and a distinct tapering lateral lobe with a large ejaculatory canal aperture. Throughout growth, there was an increment in number and/or size of the secondary cuticle structures, such as setae, spines, and sensilla. Morphological changes in the second gonopod are not abrupt during the ontogenetic development, with the girdle in the apical region and the median process becoming more prominent and tapered. Although to clearly determine the sexual maturity, information on the gonadal development (physiological sexual maturation) is needed, we observed that the gonopods morphology could provide important information to determine the sexual maturation. In our analyses, the morphological maturity occurred in line with the physiological maturity, both diagnosed in the size class 5.

No. of bitstreams: 0 Previous issue date: 2021-06-01 Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) Purpose: To describe three new species of Cosmetocleithrum in the gills of Trachelyopterus galeatus (Siluriformes, Auchenipteridae) from Aguapeí River, Upper Paraná River basin, São Paulo State, Brazil. Methods: Fifty-three specimens of T. galeatus were captured in the mouth of the Aguapeí River from August 2013 to June 2014. Monogeneans were mounted unstained in Hoyer’s and Gray and Wess’s medium. Results: Cosmetocleithrum spathulatum sp. n., Cosmetocleithrum baculum sp. n., and Cosmetocleithrum galeatum sp. n. differ from all known congeneric species mainly in the morphology of the accessory piece (i.e. spatulate-shaped, claviform, and a straight rod with hook-shaped distal portion, respectively). Also, the three new species share hooks with different sizes with hooks pairs 5 and 7 bigger than others and with an erect delicate point, inconspicuous thumb, longer shaft, and slender shank. Conclusions: To date, 18 species of Cosmetocleithrum were recognised parasitizing siluriforms in the Neotropical region. The present study expands the number to 21 species, however, despite this increase, the number of known taxa of monogeneans in neotropics is far from representing the ideal situation.

This study reports the first records of the emerald-eyed tree frog (Boana crepitans), amazon waterfrog (Lithobates palmipes), star-fingered frog (Pipa pipa), and hemprich’s coral snake (Micrurus hemprichii hemprichii) within the states of Maranhão in the northeastern region and Tocantins in the northern region of Brazil. The first state records of Boana crepitans, Pipa pipa and Micrurus h. hemprichii in Tocantins, and Lithobates palmipes in Maranhão, appear in highly climatically suitable areas within the Species Extent of Occurrences (EOO), as predicted in Ecological Niche Modelling (ENM). Our new records of Pipa pipa and Micrurus h. hemprichii, compared to the ENM predictions, represent their southeastern distributional range limits. Our results also suggest that the current gaps on the distributional species ranges probably result from the lack of herpetological surveys in those regions.

Prevalence and mean intensity of infection by location showed the following results: ARIE Mata de Goiamunduba (60.8 % and 10.4 ± 8), RPPN Engenho Gargaú (83.3 % and 20.8 ± 19.7) and Benjamim Maranhaõ Botanical Garden (70.4 % and 7.78 ± 5.8). We provide the first records of helminth infection for the lizard D. nordestina, in which three species of nematodes, Aplectana sp., Cosmocerca sp. and Physaloptera lutzi and one trematode Haplometroides odhneri were recovered. Trematodes of the genus Haplometroides were previously known as parasites only in snake and amphisbaenian hosts in South America. Now, our study provides the first record of a species belonging to this genus parasitizing lizards. In conclusion, our study shows that D. nordestina have a depleted helminth fauna (three species at maximum), similar to other studies with lizards of this family in Brazil and that its parasite abundance is related to host snout-vent length, but not to the sex.

Seventy one of the 127 lizards examined (56%) were infected with four nematode species: Physalopteroides venancioi and Physaloptera sp. (Physalopteridae), Strongyluris oscari (Heterakidae), and Parapharyngodon alvarengai (Pharyngodonidae), the latter being the component species (prevalence 53.5%; mean intensity of infection 3.37 ± 2.0; discrepancy index D = 0.69). The helminth P. alvarengai infected M. arajara throughout the year and showed increased infection rates in July, at the beginning of the dry season. In addition to the relationship with seasonality, lizards with greater body length and/or body mass were more infected. Relationships between number of parasites and body mass and with the sexes of lizards, on the other hand, were not found. Mabuya arajara represents a new host for these nematodes. This study contributes to the knowledge of the helminth fauna associated with the digestive tract of lizards from South America and the Caatinga domain.

International audience; Oxygen isotope compositions of bone phos- phate (δ18Op) were measured in broiler chickens reared in 21 farms worldwide characterized by contrasted lati- tudes and local climates. These sedentary birds were raised during an approximately 3 to 4-month period, and local precipitation was the ultimate source of their drink- ing water. This sampling strategy allowed the relationship to be determined between the bone phosphate δ18Op values (from 9.8 to 22.5‰ V-SMOW) and the local rainfall δ18Ow values estimated from nearby IAEA/WMO stations (from −16.0 to −1.0‰ V-SMOW). Linear least square fitting of data provided the following isotopic fractionation equation: δ18Ow = 1.119 (±0.040) δ18Op − 24.222 (±0.644); R2 = 0.98. The δ18Op–δ18Ow couples of five extant mallard ducks, a common buzzard, a European herring gull, a common ostrich, and a greater rhea fall within the predicted range of the equa- tion, indicating that the relationship established for extant chickens can also be applied to birds of various ecologies and body masses. Applied to published oxygen isotope com- positions of Miocene and Pliocene penguins from Peru, this new equation computes estimates of local seawater similar to those previously calculated. Applied to the basal bird Confuciusornis from the Early Cretaceous of Northeastern China, our equation gives a slightly higher δ18Ow value com- pared to the previously estimated one, possibly as a result of lower body temperature. These data indicate that caution should be exercised when the relationship estimated for mod- ern birds is applied to their basal counterparts that likely had a metabolism intermediate between that of their theropod dino- saur ancestors and that of advanced ornithurines.

Times Cited: 0; International audience; The fauna of phytoseiid mites in the state of Mato Grosso do Sul, in midwestern Brazil, is poorly known. The tomato red spider mite, Tetranychus evansi Baker and Pritchard, is an important pest of Solanaceae in several countries, but it is usually found in low densities in Brazil. It has been hypothesized that this is due to the effect of natural enemies. The objective of this study was to identify phytoseiid mites from Mato Grosso do Sul associated with T. evansi, to identify promising biological control agents for T. evansi in Africa. A survey was conducted in October – November 2002, sampling more than 70 plant species of 30 families, including 16 solanaceous species. The results of this survey provide some additional information to the scant knowledge on the phytoseiids from Mato Grosso do Sul. In total, 471 phytoseiids were collected, belonging to 12 Amblyseiinae and two Phytoseiinae species. The most frequent and abundant species was Euseius citrifolius Denmark and Muma, followed by Euseius concordis (Chant). Also, 3,493 tetranychids were found. Tetranychus evansi was found in Aquidauna on Solanum americanum (Miller), associated with E. citrifolius and Typhlodromalus aripo De Leon; in Corumba, on S. americanum associated with E. concordis and Neoseiulus idaeus Denmark and Muma; and in Dourados, on Solanum lycopersicum (L.), associated with E. citrifolius, Proprioseiopsis mexicanus (Garman) and Proprioseiopsis ovatus (Garman). However, none of the phytoseiids found are considered to be a promising biological control agent of T. evansi, based on both their inconsistent association with the pest and on available information about each species.

Não encontramos infecção parasitária nos pulmões dos espécimes de T. semitaeniatus. Entretanto, foram encontradas duas espécies de parasitas nos hospedeiros T. hispidus, os pentastomídeos Raillietiella mottae e os nematódeos Rhabdias sp. A prevalência geral de infecção foi de 5%. A prevalência de infecção de R. mottae foi de 2,5% correspondendo a apenas um parasita por hospedeiro. A prevalência de infecção de Rhabdias sp. foi de 2,5% e a amplitude de infecção de 1-2 parasitas por hospedeiros. Esses resultados compreendem o primeiro registro de Rhabdias infectando lagartos da família Tropiduridae em toda a região Neotropical. Apresentamos também uma comparação com os parâmetros de infecção pulmonar por parasitas incluindo os estudos mais recentes no Brasil. We present data on pulmonary infection rates by parasites in the lizards Tropidurus hispidus Spix, 1825 and T. semitaeniatus (Spix, 1825) living sympatrically in the Chapada do Araripe mountain Range, northeastern Brazil. We found no parasite pulmonary infection in T. semitaeniatus. However, two pulmonary parasite species were found in the T. hispidus hosts, the pentastomid Raillietiella mottae Almeida, Freire and Lopes, 2008 and the nematode Rhabdias sp. Overall prevalence was 5%. Prevalence of R. mottae was 2.5% and corresponded to only one parasite on each infected host. Prevalence of Rhabdias sp. was 2.5% and the range of infection was 1-2 parasites per host. This represents the first record of Rhabdias infecting lizards of the family Tropiduridae in the Neotropical region. Furthermore, we present a comparison of parameters of infection by pulmonary parasites including some recent studies in Brazil.

Foram coletados 194 lagartos, sendo 76 espécimes de H. mabouia e 118 de P. pollicaris. Seis espécies de parasitas foram encontradas infectando H. mabouia: Oochoristica sp., Parapharyngodon sceleratus, Physaloptera retusa, Physalopteroides venancioi, Spauligodon oxkutzcabiensis e Raillietiella mottae; enquanto em P. pollicaris foram encontradas quatro espécies: Oochoristica sp., P. sceleratus, P. retusa, and S. oxkutzcabiensis. Três novos registros de hospedeiros são reportados: P. retusa em H. mabouia e Oochoristica sp. e P. retusa infectando P. pollicaris. Cerca de 75% dos parasitas encontrados foram compartilhados pelas espécies de lagartos. Ainda, H. mabouia apresentou maior diversidade de parasitas do que P. pollicaris (6 espécies versus 4), enquanto P. pollicaris possui maior intensidade de infecção media do que H. mabouia (1.536 versus 121). Helminths and pentastomids were examined in exotic Hemidactylus mabouia and native Phyllopezus pollicaris lizards, living synanthropically in an urban area in the municipality of Crato, Ceara state, northeastern Brazil. A total of 194 lizards were collected, being 76 specimens of H. mabouia e 118 specimens of P. pollicaris. Six parasite species were found infecting H. mabouia: the cestode Oochoristica sp., the nematodes Parapharyngodon sceleratus, Physaloptera retusa, Physalopteroides venancioi, and Spauligodon oxkutzcabiensis and the pentastomid Raillietiella mottae; while four parasite species were found associated with P. pollicaris: Oochoristica sp., P. sceleratus, P. retusa, and S. oxkutzcabiensis. Three new host records were reported: P. retusa infecting H. mabouia and P. retusa and Oochoristica sp. infecting P. pollicaris. About 75% of the parasites species found were shared by both lizards. Moreover, H. mabouia showed greater diversity than P. pollicaris (6 versus 4 species), while P. pollicaris had higher intensity of infection than H. mabouia (1536 versus 121 specimens).

The parameters of infection by lung parasites from two sympatric lizards, Mabuya arajara and Anolis brasiliensis, from the Atlantic Rainforest of the lower slope of Chapada do Araripe in Northeastern Brazil were analyzed between September, 2009 and July, 2010. A total of 202 lizards were collected. 125 specimens were from Mabuya arajara and 77 from Anolis brasiliensis. M. arajara was infected by the pentastomid Raillietiella mottae while A. brasiliensis was infected by the nematode Rhabdias sp., with an overall prevalence of 1.6% and 28.6%, respectively. The mean intensity of infection by Rhabdias sp. was 3.63 ± 2.58 (range 1-15). The body size and sex of lizards did not influence the intensity of infection by Rhabdias sp. The overall prevalence was also not different between males and females hosts in A. brasiliensis. Both Anolis brasiliensis and Mabuya arajara represent a new host to Rhabdias sp. and Raillietiella mottae, respectively.

Embora esse táxon seja muito importante para a compreensão da filogenia dos Metazoa, tem recebido pouca atenção. No Brasil, existem poucas coleções que abrigam espécies de pentastomídeos, quais sejam: a Coleção Helmintológica do Instituto Oswaldo Cruz (CHIOC), a Coleção de Invertebrados do Laboratório de Zoologia da Universidade Regional do Cariri (LAZ-URCA) e a Coleção Helmintológica do Laboratório de Parasitologia de Animais Silvestres (LAPAS). O presente trabalho descreve as espécies de pentastomídeos depositados na Coleção Helmintológia do LAPAS. O trato respiratório e as cavidades do corpo dos répteis foram removidos e analisados sob Microscópio Esteroscópico; quando encontrados os pentastomídeos, foram montados slides em meio Hoyer e identificados. Foram identificadas quatro espécies e outras três ficaram identificadas no nível de gênero, tendo sido registrados quatro novos hospedeiros para as espécies de pentastomídeos. Pentastomida is a taxon of parasitic organisms infecting generally the respiratory system of vertebrates, mainly reptiles. Although this taxon is very important for understanding the phylogeny of the Metazoa, it has received little attention. In Brazil, there are few collections that include species of pentastomids, that is, only the Helminthological Collection of the Oswaldo Cruz Institute (CHIOC), the Invertebrate Collection of the Zoology Laboratory of the Regional University of Cariri (LAZ-URCA) and the Helminthological Collection of the Botucatu Institute of Biosciences (CHIBB). The present study describes the species of pentastomids deposited in CHIBB. When found, the pentastomids were mounted on slides in Hoyer's medium and identified. Four species of pentastomids were recognised and three others were identified at the genus level, while four new hosts for the species of pentastomids were recorded.

Dos 56 lagartos coletados (26 fêmeas, 27 machos, e 3 juvenis), 40 (prevalência total de 71,42%) estavam infestados por ácaros. Entre os sites de infestação, as bolsas de ácaros foram os mais infestados pelas larvas de E. alfreddugesi, enquanto Geckobiella sp. foi encontrado distribuído uniformemente sob as escamas por todo o corpo dos hospedeiros. Os espécimes fêmeas de T. hispidus parasitados por E. alfreddugesi tinham uma infestação média de 8,57 ± 3,63, 1-27, enquanto os machos tinham uma média de infestação de 11,90 ± 2,63, 1-25. Os espécimes fêmeas parasitados por Geckobiella sp. tinham uma infestação média de 5,91 ± 2,28, 1-25, enquanto que os machos tinham uma infestação média de 5,43 ± 1,52, 1-23. Sete espécimes estavam também infestados por ovos e formas imaturas de ácaros não identificados (infestação média de 2,28 ± 0,89, 1-7). Não houve diferenças significativas entre a prevalência total de ácaros em machos (70,4%) e fêmeas (65,4%) adultas. As médias dos tamanhos corporais não influenciaram as taxas de infestação. A intensidade de infestação média por E. alfreddugesi (10,2 ± 8,7) foi significativamente maior do que a encontrada para Geckobiella sp. (5,9 ± 6,8). T. hispidus constitui um novo registro de hospedeiro para ácaros do gênero Geckobiella. Parasitism of the lizard Tropidurus hispidus by Geckobiella sp. and by larvae of Eutrombicula alfreddugesi was examined in a mountainous area in Chapada do Araripe (07° 16' S and 39° 26' W), southern Ceará State, Brazil. of the 56 lizards collected (26 females, 27 males, and 3 juveniles), 40 (total prevalence of 71.42%) were infested by mites. Mite-pockets were the sites most heavily infested by E. alfreddugesi larvae, while Geckobiella sp. was found uniformly distributed under scales over the host's entire body. The female specimens of T. hispidus parasitised by E. alfreddugesi had an average infestation rate of 8.57 ± 3.62, 1-27, while the males had an average infestation rate of 11.90 ± 2.63, 1-25. The female specimens parasitised by Geckobiella sp. had an average infestation rate of 5.91 ± 2.28, 1-25, while the males had an average infestation rate of 5.43 ± 1.52, 1-23. Seven specimens were also infested by eggs and immature forms of unidentified mites (average 2.28 ± 0.89, 1-7). There were no significant differences between the total prevalence of mites on adult male (70.4%) and adult female (65.4%) lizards. The body sizes of the hosts did not influence their infestation rates. The average infestation intensity by E. alfreddugesi (10.2 ± 8.7) was significantly greater than the average infestation intensity by Geckobiella sp. (5.9 ± 6.8). T. hispidus is the new host record to Geckobiella mites.
