The genus Apodrosus Marshall is newly recorded for, and revised for Cuba. Nine new species are recognized as follows: Apodrosus alberti (type locality, Granma, Parque Nacional Pico Turquino), A. alternatus (type locality, Guantánamo, El Yunque), A. franklyni (type locality, Cienfuegos, Parque Nacional Pico San Juan), A. griseus (type locality, Santiago de Cuba, Siboney-Jutici Ecological Reserve), A. mensurensis (type locality, Holguin, Parque Nacional La Mensura-Piloto), A. pseudoalternatus (type locality, Matanzas, Varahicacos), A. beckeli (type locality, Guantánamo, 8 km W. Imias), A. sandersoni (type locality, Guantánamo, Loma Lafarola), and A. zayasi (type locality, Cienfuegos, Parque Nacional Pico San Juan). A key for their identification, descriptions, summaries of natural history information and data on distributions are presented. A molecular phylogeny based on 11 species of Apodrosus from Cuba, Hispaniola and Puerto Rico is reconstructed. A sister group relationship between Polydrusus and Apodrosus is recovered with a limited sampling of the former genus. The monophyly of Apodrosus is recovered with strong support. Cuban Apodrosus are not monophyletic. Five of the six sampled Cuban species form a clade, sister to an undescribed Apodrosus species from the Dominican Republic; and, Apodrosus alternatus is sister to A. quisqueyanus Girón & Franz, 2010, a species from the Dominican Republic. Biogeographic implications for Cuban species are discussed in light of the phylogeny.

A new monotypic genus of Chilocorini, Renius Li & Wang, gen. n., with a new species R. cornutus Li et Wang, sp. n. is described from Tibet, China. All diagnostic features are illustrated. The relationships with other genera of Chilocorini are discussed and a key to Chinese genera of Chilocorini is provided.

An account is given of the twelve species of Leptomias Faust, 1886 occurring in the Sichuan Province of China, including the description of a new species, Leptomias verticalis Ren, Zhang & Song, sp. n. from Jiulong County, Southwest Sichuan. New locality data and remarks for the other eleven species, a key to and distribution map of all twelve Sichuan species are provided. Leptomias chenae Alonso-Zarazaga & Ren is transferred to Geotragus Schoenherr, 1845, where its valid name is G. granulatus (Chao, 1980), comb. n. in application of Art. 59.4. Structural details of Leptomias verticalis and Geotragus granulatus are illustrated.

The subterranean ground beetle genus Guiaphaenops Deuve, 2002 is taxonomically reviewed. This poorly known genus is different from Guizhaphaenops Vigna Taglianti, 1997 in having convex propleura which is visible from above and elytral chaetotaxy especially the humeral group of the marginal umbilicate series, in which the 1st pore is transversely and backwardly shifted. The second species, G. deuvei Tian, Feng & Wei, sp. n., is described from a limestone cave at Yangli Cun (Village), Lingyun Xian (County), Baise Shi (Prefecture), northwestern Guangxi Zhuang Autonomous Region, China. A key to the species and a distribution map of Guiaphaenops are also provided.

Yumtaax Boucher (Coleoptera: Passalidae) is an endemic genus from the temperate sierras of Mexico and includes six narrowly distributed species. Yumtaax species have been assigned to several genera of Passalidae throughout history, and a phylogenetic approach is necessary to understand species delimitation and interspecific relationships. This study reconstructed the molecular phylogeny of six Yumtaax morphotypes using parsimony and Bayesian analysis of DNA sequence data from the ribosomal nuclear gene region 28S and the mitochondrial gene regions 12S and cytochrome oxidase I (COI) in addition to morphological characters. Analyses recovered two well-supported Yumtaax clades (the Yumtaax laticornis and Yumtaax imbellis clades) that are possible sister lineages. One synapomorphic morphological character state and the geographic isolation of the group provide corroborative evidence for monophyly. Molecular phylogenetic analyses and traditional morphological examinations also resulted in the discovery of two undescribed Yumtaax species and the discovery of two separate evolutionary lineages (cryptic species) within Yumtaax recticornis. As a result we describe three new species (Yumtaax veracrucensis Beza-Beza, Reyes-Castillo & Jameson, sp. n., Yumtaax cameliae Beza-Beza, Reyes-Castillo & Jameson, sp. n., and Yumtaax jimenezi Beza-Beza, Reyes-Castillo & Jameson, sp. n.), redescribe two species (Yumtaax recticornis [Burmeister 1847] and Yumtaax laticornis [Truqui 1857]), and provide a key to all nine Yumtaax species. This study is one of two studies to use molecular data to evaluate the evolutionary relationships of a genus of Bess Beetles (Passalidae), an ecologically important insect group exhibiting low morphological variability and heretofore lacking molecular phylogenetic study.

The genus Tobochares Short & García, 2007 is revised. A combination of morphological and molecular data provide support for ten distinct species. Five new species are described: T. canaliculatus sp. n. (Venezuela), T. canthus sp. n. (Venezuela), T. emarginatus sp. n. (Suriname), T. kusad sp. n. (Guyana), and T. pallidus sp. n. (Venezuela). All four preexisting species are redescribed. A tenth species, known from a single female from Venezuela, is left undescribed pending the collection of additional specimens. New collecting records are provided for T. sulcatus Short & García, 2007 and T. kasikasima Short, 2013. Tobochares sipaliwini Short & Kadosoe, 2011 is newly recorded from Guyana. All species are associated with seepage or wet rock habitats, although some species have also been found along the margins of streams that flow over rocky substrates. High-resolution images including scanning electron micrographs are provided, as well as a key to species and habitat photographs.

The genera Anexodus Pascoe, 1866 and Pantilema Aurivillius, 1911 (Cerambycidae: Lamiinae: Morimopsini), both endemic to Borneo, are revised. Four species of Anexodus are recognized: A. aquilus Pascoe, 1886 (Malaysia: Sabah), A. sarawakensis Sudre, 1997 (Malaysia: Sarawak), A. syptakovae sp. n. (Malaysia: Sarawak), and A. tufi sp. n. (Brunei). Pantilema is a monotypic genus containing P. angustum Aurivillius, 1911 (Malaysia: Sarawak) which is known only from the holotype. For the first time, genital structures are studied in these genera. An identification key for the species of Anexodus is provided and their intraspecific morphological variability and distributions are discussed.

The Oriental species of the relictual genus Bolitogyrus are revised based on 200 specimens. An updated description of the genus is provided, including additional putative synapomorphies. Fifty valid Oriental species are diagnosed herein and the following nineteen are described as new to science: B. concavus sp. n.; B. confusus sp. n.; B. himalayicus sp. n.; B. khasiensis sp. n.; B. luteus sp. n.; B. mulayitensis sp. n.; B. nanus sp. n.; B. nokrek sp. n.; B. pecki sp. n.; B. pederseni sp. n.; B. phukhieo sp. n.; B. rougemonti sp. n.; B. sepilok sp. n.; B. schillhammeri sp. n.; B. smetanai sp. n.; B. solodovnikovi sp. n.; B. temburong sp. n.; B. tigris sp. n.; and B. tumidus sp. n. The following synonymies are proposed: Cyrtothorax borneensis Cameron, 1942, syn. n. = Cyrtothorax caesareus Bernhauer, 1915; Cyrtothorax octomaculatus Cameron, 1937 syn. n. = Quedius ornatipennis Wendeler, 1927. Quedius (Raphirus) ornatipennis is moved to Bolitogyrus as B. ornatipennis (Wendeler), comb. n. A lectotype is designated for Cyrtothorax rufipennis Cameron, 1937. Several species are named in recognition of conservation efforts to protect tropical primary forests in Asia that are important to the survival of many Bolitogyrus species. All available bionomic and distributional data for Oriental Bolitogyrus are summarized, and an identification key is provided.

A study on the genus Micrambe Thomson, 1863 (Coleoptera, Cryptophagidae) from Madagascar and Réunion is presented. Six species are hitherto known from these countries: M. apicalis Grouvelle, M. brevitarsis Bruce, M. consors Grouvelle, M. madagascariensis Grouvelle, M. modesta (Grouvelle), and M. reuninensis Lyubarsky. A new species, M. leonardoi sp. n., is formally described from Boorg-Murat, Réunion Island. A key is presented to enable their identification. Micrambe consors Grouvelle previously known only from Congo is reported here for the first time from Madagascar.

The ground beetle genus Bembidion is a highly diverse group of small predators with more than 1.200 described extant species. In contrast, only two representatives of Bembidion are known from the amber fossil record and their position within this mega-diverse genus is dubious. Here, we address the taxonomic position of these two extinct Bembidion species (B. succini Giebel, 1856 and B. christelae Ortuño & Arillo, 2010). Based on the insufficient description and the missing type specimen, B. succini, nomen dubium, cannot be assigned to the genus Bembidion and/or to the tribe Bembidiini with certainty. The subgenus Archaeophilochthus Ortuño & Arillo, 2010 was erected for the second extinct species, B. christelae, based on external characters. However, this species seems indistinguishable to members of the earlier described subgenus Philochthemphanes Netolitzky, 1943 which comprises about extant 10 species distributed in East and Southeast Asia. Furthermore, we describe two new species, B. bukejsi sp. n. and B. alekseevi sp. n., from the Eocene Baltic amber using X-ray microscopy. Based on external and genital morphology including endophallic structures, we erected the monotypic subgenus Eodontium subgen. n. for B. bukejsi sp. n., which is probably related to the subgenera Andrewesa Netolitzky, 1931, the Hydrium complex, or the Odontium series sensu Maddison (2012). On the other hand, B. alekseevi sp. n. can be assigned to the subgenus Eupetedromus Netolitzky, 1911. The occurrence of representatives of at least two species groups adapted to a temperate climate suggests the presence of at least locally temperate climates in Baltic amber forests.

Teratolytta krejciki sp. n. from Munzur range (E Turkey) and a female belonging to a possible new species from the eastern Pontus range (N Turkey) are described and figured. New records of Teratolytta gentilis from southern Turkey are also provided. Difficulties to recognize females of this genus are discussed and a tentative key to the females of all species is proposed with the addition of a photographic plate.

Two new species of anophthalmic ground beetles belonging to the subfamily Trechinae are described: Cimmeritodes (Zhecimmerites) parvus Tian & Li, sp. n. and Wanoblemus wui Tian & Fang, gen. n., sp. n. Both were discovered in the limestone caves of Anhui Province in eastern China. Cimmeritodes (Zhecimmerites) parvus was found in caves Ziwei Dong, Xianren Dong and Qingtai Dong, whereas Wanoblemus wui was discovered in cave Baiyun Dong. This is the first record of cavernicolous ground beetles in Anhui Province, eastern China.

The Stenus flammeus group is proposed and twelve new species of the group are described: Stenus corniculus sp. n., Stenus daicongchaoi sp. n., Stenus jiajinshanus sp. n., Stenus jindingianus sp. n., Stenus paraflammeus sp. n., Stenus pengzhongi sp. n., Stenus pseudoflammeus sp. n., Stenus punctidorsus sp. n., Stenus tuyueyei sp. n., Stenus xilingmontis sp. n., and Stenus zhoudeyaoi sp. n. from Sichuan Province, and Stenus dabashanus sp. n. from Shaanxi Province. Their diagnostic characters are illustrated and a key to species of the group is provided.

Diagnostics, images of habitus and genital structures, distribution, bionomics information and new locality data are provided for the newly recorded species. A new checklist with 189 species of aleocharines recorded from the province is presented.

As molecular identification method, DNA barcoding based on partial cytochrome c oxidase subunit 1 (COI) sequences has been proven to be a useful tool for species determination in many insect taxa including ground beetles. In this study we tested the effectiveness of DNA barcodes to discriminate species of the ground beetle genus Bembidion and some closely related taxa of Germany. DNA barcodes were obtained from 819 individuals and 78 species, including sequences from previous studies as well as more than 300 new generated DNA barcodes. We found a 1:1 correspondence between BIN and traditionally recognized species for 69 species (89%). Low interspecific distances with maximum pairwise K2P values below 2.2% were found for three species pairs, including two species pairs with haplotype sharing (Bembidion atrocaeruleum/Bembidion varicolor and Bembidion guttula/Bembidion mannerheimii). In contrast to this, deep intraspecific sequence divergences with distinct lineages were revealed for two species (Bembidion geniculatum/Ocys harpaloides). Our study emphasizes the use of DNA barcodes for the identification of the analyzed ground beetles species and represents an important step in building-up a comprehensive barcode library for the Carabidae in Germany and Central Europe as well.

The genus Acetalius Sharp currently contains two species from Japan. In this paper, a third species, Acetalius grandis Yin & Li, sp. n., is described from eastern China. The foveal pattern of Acetalius, and polymorphism and major diagnostic features of Acetalius grandis are figured. An updated key to Acetalius species is provided.

There are three isolated mountain ranges in Taiwan including Hsueshan Range, Central Mountain Range, and Yushan Range. The rise of these mountains has resulted in the isolation of some species and caused allopatric distribution resulting in divergence and speciation events of high mountain carabids, especially the flightless carabids such as Epaphiopsis, Apenetretus, and partial Nebria. Genus Apenetretus Kurnakov (1960) is typically distributed in high mountain areas of Taiwan. Three of the currently known Apenetretus species have been described from different mountain ranges. These species include Apenetretus yushanensis Habu, Apenetretus nanhutanus Habu, and Apenetretus smetanai Zamotajlov and Sciaky. In this study, a new species is described from Hsueshan, a mountain separated from the ranges of the previous known species, Apenetretus hsueshanensis sp. n. A key to the Taiwanese Apenetretus is included. A reconstructed phylogeny of the Taiwanese Apenetretus is introduced with the use of mitochondrial cytochrome c oxidase subunit I (COI) gene. Molecular data and geographical distribution of Apenetretus support the morphological characteristics observed among those mountain-isolated species and confirms the new species as being distinctly different. Moreover, lineage calibration suggests that the southern Apenetretus yushanensis is the most distant one compared to the other three northern Apenetretus at ca. 1.81 million years ago (mya), while the divergence time of Apenetretus hsueshanensis to its sister group was dated to 0.94 mya.

A new species, Anomognathus athabascensis Klimaszewski, Hammond & Langor, sp. n., and nine new provincial records including one new country record of aleocharine beetles are presented for the province of Alberta. Diagnostics, images of habitus and genital structures, distribution, natural history information and new locality data are provided for the newly recorded species. A checklist for all recorded aleocharines from Alberta is updated.

The Holarctic diving beetle genus Graphoderus (Dytiscinae, Aciliini) contains relatively few and well-known species but these may still be difficult to identify based on external characters. A taxonomic problem in the eastern Palearctic was discovered that relates to the Palearctic Graphoderus zonatus (Hoppe, 1795) and the Nearctic Graphoderus perplexus Sharp, 1882. Based on qualitative and quantitative characters, especially on male genitalia which have been poorly studied in the past, it is shown that eastern Palearctic specimens identified by previous authors as either of the two species in fact belongs to a third species. The synonymized name Graphoderus elatus Sharp, 1882, is reinstated as a valid species (stat. n.) and a lectotype is designated from the mixed syntype series. The male genitalia of all known Graphoderus species have been examined and an illustrated identification key to the genus is provided. The three species in the complex of focus, Graphoderus elatus, Graphoderus zonatus and Graphoderus perplexus are found to have allopatric distributions; Graphoderus perplexus in the Nearctic region, Graphoderus zonatus in the west Palearctic region and eastwards to the Yenisei-Angara river and Graphoderus elatus east of the Yenisei-Angara river. All previous records of either Graphoderus zonatus or Graphoderus perplexus in the east Palearctic, east of the Yenisei-Angara river turned out to be misidentified Graphoderus elatus. This conclusion also brings with it that dimorphic females, thought only to be present in the single subspecies Graphoderus zonatus verrucifer (CR Sahlberg, 1824), proved to be present also in a second species, Graphoderus elatus. The dimorphic female forms is either with dorsally smooth elytra and pronotum or conspicuously granulated elytra and wrinkly pronotum. As has been shown in Graphoderus zonatus verrucifer there is a correlation between the occurrence of granulate female forms in a population and an increase in the number of adhesive discs on pro- and mesotarsus in males within Graphoderus elatus.

The subgenus Tinotus Sharp, 1833, stat. n., of the genus Aleochara Gravenhorst, 1802 (Aleocharini: Aleocharina) from Japan, Taiwan, and the Russian Far East is revised. Tinotus is a new record from the latter two regions. Three species are recognized: Aleochara (Tinotus) morion Gravenhorst, 1802, comb. n. [Japan (new record), the Russian Far East (new record)], Aleochara (Tinotus) eoa nom. n. [replacement name for Tinotus japonicus Cameron, 1933; Japan, Taiwan (new record)], and Aleochara (Tinotus) takashii sp. n. (central Honshû, Japan). The systematic position of Tinotus is discussed. All species are (re-)described, keyed, and figured. A world checklist of Tinotus species, comprising 40 valid species, is provided in an appendix. Additional taxonomic changes are proposed, including a new synonymy, a revalidation, 13 new replacement names, and 27 new combinations.

The karyotypes of three species of Timarcha Latreille, 1829 have been analysed. T. (Metallotimarcha) metallica (Laicharting, 1781), has 18 + Xyp male meioformula and 2n = 38 chromosomes, similar to those found in the two species of subgenus Americanotimarcha Jolivet, 1948, in agreement with morphological and molecular phylogenetic grounds. T. (Timarcha) carmelenae Petitpierre, 2013 displays 9 + Xyp and 2n = 20 chromosomes as in morphologically related Andalusian species, whereas T. (Timarcha) parvicollis ssp. seidlitzi Kraatz, 1879 shows 11 + Xyp and 2n = 24 chromosomes, clearly differing from the previous species. These results are discussed in order to get an insight into the main trends of the chromosomal evolution in Timarcha.

Pseudoogeton maoxianum sp. n. is described from Sichuan, China. A key to the males of the species of Pseudoogeton Masumoto, 1989 is presented.

The monotypic genus Satrapister Bickhardt, 1912 is redescribed and figured. Its tentative position in the recently performed phylogeny of the subfamily, inferred from a new analysis based on the available morphological characters is discussed. Lectotype of Satrapister nitens Bickhardt, 1912 is designated.

The formely monotypic Neotropical genus Megalocraerus Lewis is revised to include five species, known from southeastern Brazil to Costa Rica: Megalocraerus rubricatus Lewis, Megalocraerus mandibularis sp. n., Megalocraerus chico sp. n., Megalocraerus madrededios sp. n., and Megalocraerus tiputini sp. n. We describe the species, map their distributions, and provide a key for their identification. Their subcylindrical body form and emarginate mesosternum have previously hindered placement to tribe, although their curent assignment to Exosternini now appears well supported by morphological evidence. Nothing is known of the natural history of the species.

All Taiwanese species formerly classified the genus Phyllobrotica Chevrolat, 1836 are revised. Jolibrotica Lee & Bezděk, gen. n., is described for Phyllobrotica sauteri (Chûjô, 1935) (Taiwan, China: Guangxi) and Phyllobrotica chujoi Kimoto, 1969 (Taiwan). Phyllobrotica shirozui Kimoto, 1969 is transferred to the genus Haplosomoides. All species are redescribed and their diagnostic characters illustrated.

Pella tianmuensis sp. n., a myrmecophile associated with Lasius (Dendrolasius) spathepus Wheeler, 1910 in West Tianmushan Natural Reserve, Zhejiang, is described, illustrated and distinguished from its congeners.

The genus Urgleptes Dillon (1956) is reviewed for Hispaniola. Five new species of Urgleptes from the Dominican Republic are described herein: Urgleptes charynae Ravin & Lingafelter, sp. n. (La Vega province), Urgleptes conjunctus Ravin & Lingafelter, sp. n. (Peravia Prov.), Urgleptes curtipennis Ravin & Lingafelter, sp. n. (Independencia Prov.), Urgleptes marionae Ravin & Lingafelter, sp. n. (Monseñor Nouel Prov.), and Urgleptes obliteratus Ravin & Lingafelter, sp. n. (Pedernales Prov.). Two additional, previously described species are newly recorded for Hispaniola: Urgleptes puertoricensis Gilmour and Urgleptes sandersoni Gilmour. It is established that Urgleptes haitiensis Gilmour is a new synonym of Urgleptes sandersoni. Thus there are seven species of Urgleptes recorded for Hispaniola. For all species photographs, illustrations, full descriptions, distribution maps, and a dichotomous key are included for their identification.

A catalogue to all known species of this subgenus is also presented.

Three new species of the genus Cryptogonus Mulsant, 1850 from China are described and illustrated: C. dulongjiangensis, C. fusiformis and C. reniformis Huo and Ren. Cryptogonus octoguttatus Mader, 1954 and C. kurosawai Sasaji, 1968 are recognized as synonymous with C. schraiki Mader, 1933. Cryptogonus hingstoni Kapur, 1948 is newly recorded from China. A species list of the genus Cryptogonus is presented.

The ladybird Henosepilachna argus Geoffroy, 1762 has been cytogenetically studied. In addition we have conducted a review of chromosome numbers and the chromosomal system of sex determination available in the literature in species belonging to the genus Henosepilachna and in its closely related genus Epilachna. Chromosome number of H. argus was 2n=18, including the sex chromosome pair, a common diploid chromosome number within the tribe Epilachnini. The study of prophase I meiotic chromosomes showed the typical Xyp "parachute" bivalent as in the majority of species of Coccinellidae. C-banding and fluorescent staining with AT-specific DAPI fluorochrome dye have been carried out for the first time in H. argus. C-banding technique revealed that heterochromatic blocks are pericentromerically located and DAPI staining showed that this heterochromatin is AT rich. Fluorescence in situ hybridizations using rDNA and the telomeric TTAGG sequence as probes have been carried out. FISH using rDNA showed that the nucleolar organizing region is located on the short arm of the X chromosome. FISH with the telomeric sequence revealed that in this species telomeres of chromosomes are composed of the pentanucleotide TTAGG repeats. This is the first study on the telomeric sequences in Coccinellidae.

Two new ground beetle subspecies, Omphreus (Omphreus) morio sandeli ssp. n. (from Mts. Zelengora and Maglić, eastern Bosnia and Herzegovina) and Omphreus (Omphreus) morio durmitorensis ssp. n. (from Mt. Durmitor, northwestern Montenegro) are here described and diagnosed. The male and female genitalia and other taxonomically important characters are illustrated. The new taxa are distinctly different from the nearest relatives and represent both endemics and relicts inhabiting limited high-altitude Dinaric areas in Bosnia and Herzegovina and Montenegro. A key to Omphreus taxa from Montenegro and a key to subspecies of Omphreus (Omphreus) morio Dejean, 1828 are presented.

Carabus (Cathoplius) aliai was described as a separate species by Escalera in 1944 but since the 1950–60s it has been considered as a subspecies of Carabus (Cathoplius) stenocephalus Lucas, 1866. This downgrading was adopted after examining only a few specimens, due to their rarity in collections. In recent years, an important population of this taxon was rediscovered in the Tan-Tan area in southern Morocco. By combining field observations with laboratory breeding experiments including hybridization trials, and through the morphological examination of a representative number of individuals, it is confirmed that Carabus aliai is indeed a valid species. Despite close geographic distribution, the morphological and biological characteristics of Carabus aliai and Carabus stenocephalus ifniensis Zarco, 1941, its northern substitutive taxon, are very different. Carabus aliai adults are characterized by a smaller size, a slender silhouette, a more brilliant aspect, a narrower pronotum, a coarser elytral sculpture, longer legs, and a wider and a little more curved apex of the median lobe of the aedeagus. Carabus aliai larvae are also characterized by a much smaller size and the Carabus aliai pupa has a narrower thoracic area and a different chaetotaxy compared to that of Carabus stenocephalus ifniensis. Contrary to this, Carabus aliai has a life cycle belonging to the annual univoltine winter semelparous type. Moreover, the duration of its development cycle is shorter. Carabus aliai is a sabulicolous steppe-wandering species with an intensive running activity, while Carabus stenocephalus ifniensis is a more sedentary taxon. Crossbreeding experiments showed a marked reproductive isolation between Carabus aliai and Carabus stenocephalus ifniensis. When F1 hybrids were crossed with one another, a very high mortality rate during embryonic, larval and pupal development was evident and no vital F2 neo-adults were obtained. Morphological and biological differences, together with the reproductive failure in Carabus aliai × Carabus stenocephalus ifniensis hybrids, clearly indicate that Carabus aliai is a separate Cathoplius species that is distributed in an area south of the Anti-Atlas chain, from Plage Blanche (Guelmim) to Lemsid and Bou Kra (south of Laâyoune). Carabus aliai is therefore both a Saharan desert endemic and an Atlantic resident. Moreover, it is the southernmost Carabus species of the western Palaearctic region.

Paederus (Harpopaederus) xui Peng & Li, sp. n. (Sichuan: Micang Shan) is described. Additional records of five Harpaederus species are reported. All of these species are illustrated.

The family Jacobsoniidae Heller (短跗甲科) is newly recorded from China upon the discovery of Sarothrias sinicus Bi & Chen, sp. n. (中华短跗甲) from Motuo, Southeast Xizang. Description and illustrations of the habitus and major diagnostic features of the new taxon are provided. A key to the species of Sarothrias and some ecological notes on the new species are presented.

A lectotype is designated for the Tibetan species Deronectes emmerichi Falkenström, 1936 (Currently Boreonectes emmerichi (Falkenström)), and its habitus, as well as the median lobe and parameres of its aedeagus, are figured along with additional comparative material. Material of Boreonectes emmerichi from Sikkim (BMNH) represents the first record of a Boreonectes Angus, 2010 species from India. The karyotype of Boreonectes emmerichi is described as having 26 pairs of autosomes plus sex chromosomes which are X0 (♂), XX (♀). The karyotype is most like that of Boreonectes macedonicus (Géuorguiev, 1959), but with slight differences. Additional chromosomal information is given for Boreonectes griseostriatus griseostriatus (De Geer, 1774) in the French Alps, Boreonectes griseostriatus strandi (Brinck, 1943) on the Kola Peninsula, Boreonectes multilineatus (Falkenström, 1922) in the Pyrenees and Boreonectes ibericus (Dutton & Angus, 2007) in the Spanish Picos de Europa.

Continuing surveys on the pselaphine fauna in China have revealed four undescribed species of the genus Batrisodes: Batrisodesangustelytratussp. n. (with Pachycondyla ant) and Batrisodeslongwangshanussp. n. from Zhejiang, Batrisodesbamiansp. n. (with Pseudolasius ant) from Hunan, and Batrisodessongxiaobinisp. n. (with Formica ant) from Yunnan. The genus Batrisodellus is placed as a junior synonym of Batrisodes, syn. n.; this taxonomic act results in eight new combinations:Batrisodescerberus, Batrisodescoprea, Batrisodescristatus, Batrisodesfengtingae, Batrisodeslaticollis, Batrisodeslongulus, Batrisodespalpalis, and Batrisodespunctipennis. The Russian Far East species Basitrodescornutus is transferred to Batrisodes, comb. n.

We carried out a quantitative assessment of the consumption of herbaceous plants by Opatrum sabulosum (Linnaeus, 1761) – a highly significant agricultural pest species. We researched the feeding preferences of this pest species with respect to 33 uncultivated and 22 cultivated plant species. This species of darkling beetle feeds on many uncultivated plant species, including those with hairy leaves and bitter milky sap, such as Scabiosa ucrainca (5.21 mg/specimen/24 hours), Euphorbia virgata (3.45), Solanum nigrum (3.32), Centauria scabiosa (2.47), Lamium album (2.41), Aristolochia clematitis (1.76), Chenopodium album (1.73), Arctium lappa (1.51), Asperula odorata (1.20). A high rate of leaf consumption is also characteristic for cultivated species, for example, Perilla nankinensis (5.05 mg/specimen/24 hours), Lycopersicon esculentum (3.75), Tropaeolum majus (3.29), Nicotiana tabacum (2.66), Rumex acetosa (1.96), Beta vulgaris (1.27). Opatrum sabulosum is capable of feeding on plants which are poisonous to cattle. This species of darkling beetle consumes 95.5% of the cultivated and 48.5% of the uncultivated herbaceous plants researched.

New material collected recently throughout the Afrotropical region has led to a major reassessment of taxa within the genera Anelaphinis Kolbe, 1892, Atrichelaphinis Kraatz, 1898 and other closely related genera. As a result, the name Megalleucosma Antoine, 1989 is here synonymised with Anelaphinis and a lectotype is designated for the type species, Cetonia dominula Harold, 1879. The genus Atrichelaphinis is redefined and a new subgenus, Atrichelaphinis (Eugeaphinis), is proposed for Elaphinis simillima Ancey, 1883, Elaphinis vermiculata Fairmaire, 1894, Niphetophora rhodesiana Péringuey, 1907, Atrichelaphinis deplanata Moser, 1907 (with Anelaphinis kwangensis Burgeon, 1931 as junior synonym) and Anelaphinis sternalis Moser, 1914. Additionally, three new species and one new subspecies are recognised and described in this new subgenus: Atrichelaphinis (Eugeaphinis) bomboesbergica sp. n. from South Africa; Atrichelaphinis (Eugeaphinis) bjornstadi sp. n. from Tanzania; Atrichelaphinis (Eugeaphinis) garnieri sp. n. from south–east Africa (Tanzania, Zimbabwe); and Atrichelaphinis (Eugeaphinis) deplanata minettii ssp. n. from central Africa (Malawi, Mozambique, Congo-Kinshasa, Congo-Brazzaville, South Africa, Rwanda, Zambia, Zimbabwe). The genus Atrichelaphinis is compared to its closest relatives and two separate keys are proposed, one for Atrichelaphinis and one for the sub-Saharan genera exhibiting completely or partially fused parameres.

A new species, Orthotemnus longitarsus sp. n., is described from China, representing the first record of the genus Orthotemnus Wollaston, 1873 from China. Illustrations of diagnostic features of the new species and a key to all six species of the genus Orthotemnus (including Orthotemnus reflexus Wollaston, Orthotemnus disparilis Pascoe, Orthotemnus filiformis Champion, Orthotemnus expansus Hustache and Orthotemnus ulmi Zherichin) are provided. All type specimens of the new species are deposited in the National Zoological Museum in the Institute of Zoology, Chinese Academy of Sciences, Beijing, China.

The genus Ablattaria Reitter, 1884 (Coleoptera: Silphidae: Silphinae) is revised. Four taxa are recognized as valid species: Ablattaria arenaria (Kraatz, 1876), Ablattaria cribrata (Ménétries, 1832), Ablattaria laevigata (Fabricius, 1775) and Ablattaria subtriangula Reitter, 1905. Ablattaria laevigata var. meridionalis Ganglbauer, 1899 is newly treated as a junior subjective synonym of Ablattaria laevigata. Lectotypes are designated for Phosphuga arenaria Kraatz, 1876, Ablattaria arenaria var. punctigera Reitter, 1884, Ablattaria arenaria var. alleoni Portevin, 1926, Silpha cribrata Ménétries, 1832, Silpha laevigata Fabricius, 1775, Silpha gibba Brullé, 1832, Ablattaria gibba var. costulata Portevin, 1926, Ablattaria gibba var. distinguenda Portevin, 1926, Ablattaria gibba var. punctata Portevin, 1926 and Ablattaria subtriangula Reitter, 1905. The distribution of all taxa is mapped, based on material examined. Geometric morphometric methods were used to evaluate shape variability in Ablattaria. Results indicated sexual dimorphism in all species. Shape inconsistency was found between the sexes of all taxa when tested independently. The first two relative warp axes indicated 65.17% shape variation in males and 65.72% in females. Canonical variate analysis separated the taxa studied. There was minimal overlap between some groups in both sexes. Differences in body shape between populations of Ablattaria laevigata from Central Europe, Italy and Greece + Turkey were also examined. Relative warps implied 58.01% shape variability on both axes in males and 64.78% in females. CVA revealed noticeable overlaps between the groups, although the Italian population demonstrated a higher separation in both sexes.

Nineteen species of seed-beetles belonging to the subfamily Bruchinae (Coleoptera, Chrysomelidae) were collected in Xinjiang, China. Of these, the following four were new records for China: Bruchus affinis Frolich, 1799, Bruchus atomarius L., 1761, Bruchus loti Paykull, 1800 and Kytorhinus kergoati Delobel & Legalov, 2009. We provide an annotated checklist, illustrations and a key to the 19 species.
