A revision of the Chinese Catops Paykull 1798 of the Catops fuscus species group (Coleoptera: Leiodidae: Cholevinae)

Five species of the Catops fuscus species group are reported from China. Three species are newly described: C. hlisnikovskyi n. sp. from the Beijing municipality and Jiangsu province, C. schuelkei n. sp. from Sichuan and Yunnan provinces, and C. smetanai n. sp. from Sichuan and Yunnan provinces. Female of C. sasajii Nishikawa 2007 is described and the species is reported from Hubei, Sichuan and Yunnan provinces for the first time. Catops nigricans (Spence 1813) is reported for the first time from China (Xinjiang Uygur autonomous region). Important morphological characters are illustrated and the distribution of all species in China is mapped. Preliminar phylogenetic analysis separates (C. hlisnikovskyi n. sp.+C. fuscus fuscus Panzer 1794) as a sister clade to C. nigricans+(C. sasajii+(C. schuelkei n. sp.+C. smetanai n. sp.)), with C. paramericanus Peck & Cook 2002 as outgroup.

A new genus and a new subgenus of cavernicolous beetles from Furong Jiang valley,southwestern China (Coleoptera: Carabidae: Trechinae)

A new genus and a new subgenus of semi-aphaenopsian trechine beetles are described from Furong Jiang valley in the bordering areas of Chongqing Shi (Municipality) and Guizhou Province, southwestern China: Deuveaphaenops Tian & Huang, n. gen. (type species: Deuveaphaenops qimenxicus Tian & Huang, n. sp. from Qimenxia Cave II, Wulong Xian, Chongqing) and Furongius Tian & Huang, n. subgen. (type species: Deuveaphaenops (Furongius) gelaophilus Tian & Huang, n. sp. from cave Xianmi Dong, Daozhen Xian, Guizhou). Deuveaphaenops probably belongs to the complex of Cathaiaphaenops, Qianotrechus, Guizhaphaenops and Sinotroglodytes.     

Revision of the Chinese species of the genus Coenochilus Schaum (Coleoptera,Scarabaeidae, Cetoniinae)

Summary

The Chinese species of the genus Coenochilus Schaum, 1841 are revised, including a new species, C. pilosus n. sp. described from southern China (also from Vietnam and Laos). The lectotype for Coenochilus uncinatipes Moser, 1915 is designated, and this name is recognized as a junior synonym of C. bifoveolatus Fairmaire, 1888. Previously published synonymy of Coenochilus apicalis Westwood, 1873 and C. armiger Westwood, 1873 is confirmed based on the examination of type specimens. The neotype of C. tonkinensis Moser, 1910 is designated, and C. clinteroceroides Jákl, 2015 is synonymized with this species. Coenochilus tonkinensis is newly recorded from China, while Chinese records of C. nitidus Arrow, 1910 are verified as misidentification of C. striatus Westwood, 1873, thus C. nitidus is removed from the Chinese fauna. Diagnoses and illustrations are provided for all five Chinese species. A key to Chinese species and new distribution records are also presented.??     

The first Praesiricidae (Hymenoptera) from Northeast China

A new subfamily Rudisiricinae Gao, Rasnitsyn, Ren & Shih, n. subfam. and a new genus Rudisiricius Gao, Rasnitsyn, Ren & Shih, n. gen. with three new species R. belli Gao, Rasnitsyn, Ren & Shih n. sp., R. crassinodus Gao, Rasnitsyn, Ren & Shih, n. sp., and R. celsus Gao, Rasnitsyn, Ren & Shih, n. sp. are described and illustrated from the family Praesiricidae. The type specimens were collected from the Late Jurassic to Early Cretaceous Yixian Formation, northeastern China. The new subfamily also includes Aulidontes Rasnitsyn from the Upper Jurassic of Karatau in Kazakhstan. This is the first record of Praesiricidae in China. These well-preserved nearly-complete new fossils reported here provide additional material and structure characters about this family, which helps filling some gap in the evolution of Lower Hymenoptera.     

Species level taxonomy of the Neotropical hairstreak genus Porthecla (Lepidoptera: Lycaenidae: Theclinae: Eumaeini)

The species level taxonomy of Porthecla is revised. Six previously described species are recognized: P. ravus (Druce 1907); P. barba (Druce 1907); P. dinus (Hewitson 1867); P. porthura (Druce 1907); P. minyia (Hewitson 1867); P. gemma (Druce 1907), and another six new species are proposed: P. forasteira Faynel & Moser n. sp.; P. annette Faynel & Robbins n. sp.; P. johanna Faynel & Robbins n. sp.; P. peruensis Faynel & Moser n. sp.; P. prietoi Faynel & Busby n. sp. and P. willmotti Busby, Faynel & Moser n. sp. For each Porthecla species we present diagnostic characters, images of male and female adults, drawings of male and female genitalia, distribution maps, and notes on habitat and other biological traits. An identification key for males is provided. To stabilize names; lectotypes are designated for Thecla minyia Hewitson 1867, and Thecla gemma Druce 1907. Wing pattern resemblances between Porthecla and other genera are discussed.     

Population structure and colonization of Bactrocera dorsalis (Diptera: Tephritidae) in China,inferred from mtDNA COI sequences

The oriental fruit fly, Bactrocera dorsalis, is a serious pest of fruits and vegetables in South‐east Asia, and, because of quarantine restrictions, impedes international trade and economic development in the region. Revealing genetic variation in oriental fruit fly populations will provide a better understanding of the colonization process and facilitate the quarantine and management of this species. The genetic structure in 15 populations of oriental fruit fly from southern China, Laos and Myanmar in South‐east Asia was examined with a 640‐bp sequence of the mitochondrial cytochrome oxidase subunit I (COI) gene. The highest levels of genetic diversity were found in Laos and Myanmar. Low to medium levels of genetic differentiation (F_ST ≤ 0.134) were observed among populations. Pooled populations from mainland China differed from those in Laos and Myanmar (F_ST = 0.024). Genetic structure across the region did not follow the isolation‐by‐distance model. The high genetic diversity observed in Laos and Myanmar supports the South‐east Asian origin of B. dorsalis. High genetic diversity and significant differentiation between some populations within mainland China indicate B. dorsalis populations have been established in the region for an extended period of time. High levels of genetic diversity observed among the five populations from Hainan Island and similarity between the Island and Chinese mainland populations indicate that B. dorsalis was introduced to Hainan from the mainland and has been on the island for many years. High genetic diversity in the recently established population in Shanghai (Pudong) suggests multiple introductions or a larger number of founders.     

Phylogeny and systematics of the Acrapex apicestriata (Bethune-Baker, 1911) species complex (Lepidoptera,Noctuidae, Noctuinae,Apameini, Sesamiina) with the description of eight new species from the Afrotropics

Twelve morphologically similar species of Acrapex Hampson 1894, (Lepidoptera, Noctuidae, Noctuinae, Apameini, Sesamiina), from Western, Central and Eastern Africa are reviewed. Eight of these species are new to science and are described: Acrapex akunamatata n. sp. and A. incrassata n. sp. from Kenya; A. gracilis n. sp., A. iringa n. sp., A. lukumbura n. sp. and A. rungwe n. sp. from Tanzania; A. soyema n. sp. from Ethiopia; and A. zoutoi n. sp. from Benin. All 12 species belong to a species complex that we hereby define as the Acrapex apicestriata group. Host-plants for three of the new species are recorded: Setaria incrassata (Hochst.) Hack. for Acrapex incrassata; Cymbopogon pospishilii (K. Schum.) C.E. Hubb. for A. rungwe; and Andropogon perligulatus Stapf. for A. zoutoi. We also conducted molecular phylogenetic analyses (using maximum likelihood and Bayesian inference) on a six gene multimarker molecular dataset (four mitochondrial and two nuclear gene fragments; 4581 nucleotides in length) consisting of 15 Acrapex species (including seven species from the apicestriata group) and four outgroups species from the subtribe Sesamiina (from genera Busseola Thurau 1904, Sciomesa Tams & Bowden 1953, Pirateolea Moyal, Le Ru, Conlong, Cugala, Defabachew, Matama-Kauma, Pallangyo & Van den Berg 2010 and Sesamia Boisduval & Guenée 1852). Both maximum likelihood and Bayesian inference analyses yield a similar and well-supported topology, which supports the monophyly of the apicestriata group.     

Latest occurrences of the Mesozoic family Elcanidae (Insecta: Orthoptera), in Cretaceous amber from Myanmar and Spain

Mesozoic orthopterans of the family Elcanidae are reported (as nymphs) in amber, from the latest Albian-Cenomanian of northern Myanmar and the Albian of northern Spain. Four distinct new species in two new genera occur, Burmelcana longirostris n. gen, n. sp. in amber from Myanmar and Hispanelcana arilloi n. gen, n. sp., H. alavensis n. sp. and H. lopezvallei n. sp. from Spanish amber. Detailed preservation reveals the fine structure of the tibial spurs and spines that are so distinctive to Elcanidae, as well as details of the abdominal styli, cerci, tarsomeres, and mouthparts. Elcanidae and their stem group, Permelcanidae, are known from the Early Permian to the Early Cretaceous (Aptian), so the amber fossils represent the latest known occurrence of this clade.     

On the Genus Trypeticus Marseul (Coleoptera: Histeridae: Trypeticinae) in China

This paper describes two new species, Trypeticus fissirostrum n. sp. from Hainan and Trypeticus yunnanensis n. sp. from Yunnan Provinces, China. Three Trypeticus species having been recorded in the territory of China before this study, their total number in this country has now increased to five. A key to the Chinese species is compiled and given in the text. The type specimens are deposited in Institute of Zoology, Chinese Academy of Sciences.

Family Lasiosynidae n. fam., new palaeoendemic Mesozoic family from the infraorder Elateriformia (Coleoptera: Polyphaga)

Lasiosynidae n. fam. is proposed for the genera Lasiosyne Tan, Ren & Chih 2007 (transferred from Archostemata to Polyphaga), Anacapitis Yan 2009 Tarsomegamerus Zhang 2005 (proposed in the superfamily Chrysomeloidea) and Bupredactyla n. gen. The new family is regarded in composition of the infraorder Elateriformia without a more detailed attribution, because it demonstrates a mixture of characters of different families and superfamilies, i.e. somehow an intermediate position between the superfamilies Dascilloidea, Elateroidea, Buprestoidea and Byrrhoidea with most resemblance to Dascillidae, Schizopodidae, Eulichadidae, Ptilodactylidae and Callirrhipidae and probable more close relationship to the last three families. Four new fossil species of the genus Lasiosyne: L. daohugouensis n. sp., L. fedorenkoi n. sp., L. gratiosa n. sp., L. quadricollis n. sp., and also Bupredactyla magna n. sp. are described from the Middle Jurassic Jiulongshan Formation of eastern Inner Mongolia, China. A probable generic composition of the new family is considered. The synonymy of generic names Anacapitis Yan 2009 and Brachysyne Tan & Ren 2009, n. syn. as well as synonymy of species names Lasiosyne euglyphea Tan, Ren & Chih 2007, Pappisyne eucallus Tan & Ren 2009, n. syn. and Pappisyne spathulata Tan & Ren 2009, n. syn. are proposed.

Hammatoderus wappesi n. sp. and H. garciaorum n. sp. are described from Mexico, Veracruz and Oaxaca and Veracruz, respectively. Hammoderus brasiliensis Breuning, 1943 and Plagiohammus camillus Dillon & Dillon, 1949 are proposed as synonyms of Hammatoderus confusor (Dillon & Dillon, 1941); Plagiohammus rotundipennis Breuning, 1950 is proposed as a synonym of Hammatoderus pollinosus (Bates, 1880). A replacement name, Deliathis neonivea nom. nov., for Deliathis nivea (Breuning, 1943) n. comb., a secondary homonym of D. nivea Bates, 1869, is proposed. Three other new combinations are proposed: Deliathis imperatrix (Thomson, 1868) n. comb.; Monochamus sargi (Bates, 1885) n. comb.; and Monochamus blairi (Breuning, 1936) n. comb. Monochamus sargi and Hammatoderus pollinosus are redescribed. Hammatoderus sticticus (Bates, 1874) is newly recorded from Bolivia, with H. confusor newly recorded from Argentina and Colombia and its known distribution in Brazil expanded to include the state of Sao Paulo. Distribution of Deliathis imperatrix in Mexico is expanded to include the state of Morelos. A key to species of Hammatoderus and a key to species of Taeniotes “amazonum” group are also provided.
