The integripennis species group of Geocharidius Jeannel, 1963 (Carabidae,Bembidiini, Anillina) from Nuclear Central America: a taxonomic review with notes about biogeography and speciation

Our review recognizes 15 species of the integripennis species group of Geocharidius from Nuclear Central America, include three species previously described (Geocharidius gimlii Erwin, Geocharidius integripennis (Bates) and Geocharidius zullinii Vigna Taglianti) and 12 described here as new. They are: Geocharidius andersoni sp. n. (type locality: Chiapas, Chiapas Highlands, Cerro Huitepec) and Geocharidius vignatagliantii sp. n. (type locality: Chiapas, Motozintla, Sierra Madre de Chiapas, Benito Juárez) from Mexico; Geocharidius antigua sp. n. (type locality: Sacatepéquez, 5 km SE of Antigua), Geocharidius balini sp. n. (type locality: Suchitepéquez, 4 km S of Volcan Atitlán), Geocharidius erwini sp. n. (type locality: Quiché Department, 7 km NE of Los Encuentros), Geocharidius jalapensis sp. n. (type locality: Jalapa Department, 4 km E of Mataquescuintla), Geocharidius longinoi, sp. n. (type locality: El Progreso Department, Cerro Pinalón), and Geocharidius minimus sp. n. (type locality: Sacatepéquez Department, 5 km SE of Antigua) from Guatemala; and Geocharidius celaquensis sp. n. (type locality: Lempira Department, Celaque National Park), Geocharidius comayaguanus sp. n. (type locality: Comayagua Department, 18 km ENE of Comayagua), Geocharidius disjunctus sp. n. (type locality: Francisco Morazán, La Tigra National Park), and Geocharidius lencanus sp. n. (type locality: Lempira Department, Celaque National Park) from Honduras. For all members of the group, adult structural characters, including male and female genitalia, are described, and a taxonomic key for all members of the integripennis species group is presented based on these characters. Behavioral and biogeographical aspects of speciation in the group are discussed, based on the morphological analysis. In all cases of sympatry, pairs of closely related species show greater differences in sizes than pairs of more remotely related species. Integripennis group species occupy six different montane areas at elevations above 1300m, with no species shared among them. Major faunal barriers in the region limiting present species distributions include the Motagua Fault Zone and a gap between the Guatemalan Cordillera volcanic chain and the Honduran Interior Highlands no higher than 900m in elevation. Highest species diversity is in the Guatematan Cordillera (six species), second highest in the Honduran Interior Highlands area (four species).     

Checklist of the helminth parasites of the genus Profundulus Hubbs, 1924 (Cyprinodontiformes,Profundulidae), an endemic family of freshwater fishes in Middle-America

From December 2012 to November 2014, 267 fish belonging to the family Profundulidae (representing nine of the 11 species of the genus Profundulus) were collected in 26 localities of Middle-America, across southern Mexico, Guatemala, and Honduras, comprising the distribution range of the genus, and analyzed for helminth parasites. Additionally, a database with all ten available published accounts of the helminth parasite fauna of this genus (the only genus within the family) was assembled. Based on both sources of information, a checklist containing all the records was compiled as a tool to address future questions in the areas of evolutionary biology, biogeography, ecology and phylogeography of this host-parasite association. The helminth parasite fauna of this fish group consists of 20 nominal species, classified in 17 genera and 14 families. It includes six species of adult digeneans, five metacercariae, two monogeneans, one adult cestode, three adult nematodes and three larval nematodes. The profundulid fishes are parasitized by a specialized group of helminth species (e.g. Paracreptotrema blancoi sensu Salgado-Maldonado et al. (2011b), Paracreptotrema profundulusi Salgado-Maldonado, Caspeta-Mandujano & Martínez Ramírez, 2011, Phyllodistomum spinopapillatum Pérez-Ponce de León, Pinacho-Pinacho, Mendoza-Garfias & García-Varela, 2015, Spinitectus humbertoi Mandujano-Caspeta & Moravec, 2000, Spinitectus mariaisabelae Caspeta-Mandujano Cabañas-Carranza & Salgado-Maldonado, 2007 and Rhabdochona salgadoi Mandujano-Caspeta & Moravec, 2000), representing the core helminth fauna that are not shared with other Middle-American fish species.     

A snail in the long tail: a new Plekocheilus species collected by the ‘Comisión Científica del Pacífico’ (Mollusca,Gastropoda, Amphibulimidae)

Among the historical collection gathered by the ‘Comisión Científica del Pacífico’ during 1862–1865, type material was found of one of the species described on the basis of the material collected shortly afterwards. Inspection of the types revealed that only one specimen may be considered as type material of Bulimus aristaceus Crosse, 1869; this specimen is now designated as the lectotype. The other specimens are described as a new species, Plekocheilus (Plekocheilus) cecepeus.     

A taxonomic study of Ooctonus (Hymenoptera,Mymaridae) from Heilongjiang,China

A second species of Cheleion from Johor,Malaysia (Coleoptera,Scarabaeidae, Aphodiinae,Stereomerini)

A new species of the genus Cheleion Vårdal & Forshage, 2010, Cheleion jendeki sp. n., from Johor, Malaysia is described, illustrated and compared with the type species of the genus, Cheleion malayanum Vårdal & Forshage, 2010. Photographs of the two species are presented. The adaptation to inquilinous lifestyle of Cheleion is compared with those in other beetle groups and briefly discussed.     

A new subspecies and a new synonym of the genus Coladenia (Hesperiidae,Pyrginae) from China

The second subspecies of Coladenia buchananii (de Nicéville, 1889), viz. Coladenia buchananii separafasciata Xue, Inayoshi & Hu, ssp. n., is discovered from south Jiangxi Province and west Fujian Province, southeast China. External and genital characters of both male and female of this new subspecies are illustrated and described. Coladenia neomaeniata Fan & Wang, 2006, syn. n. is proposed to be a junior synonym of Coladenia maeniata Oberthür, 1896, and the distribution of this species is briefly discussed.     

An illustrated key to the cuckoo wasps (Hymenoptera,Chrysididae) of the Nordic and Baltic countries,with description of a new species

The Chrysididae are a group of cleptoparasitic and parasitoid aculeate wasps with a large number of rare and endangered species. The taxonomy of this group has long been confusing due to the similarity of species and extensive intraspecific variation. We present for the first time a comprehensive dichotomous key for all 74 species found in the Nordic and Baltic countries. In addition to diagnostic characters, information on the distribution and biology of each species is also presented. A new species, Chrysis borealis Paukkunen, Ødegaard & Soon, sp. n. is described on the basis of specimens collected from Fennoscandia. Chrysis gracillima Förster, 1853 is recorded as new to the Nordic and Baltic countries.     

A new species of Paracreptotrema (Digenea,Plagiorchiformes, Allocreadiidae) infecting two species of poeciliids in Río Malila of the Río Pánuco basin,Hidalgo, México,with a key to the species of the genus

Paracreptotrema rosenthali sp. n. was discovered in the intestine of Xiphophorus malinche and Pseudoxiphophorus jonesii, collected from the headwaters of Río Malila, tributary of Río Conzintla, in the Río Pánuco basin, Hidalgo, México, during 2008–2009. The new species differs from the five known species of Paracreptotrema Choudhury, Pérez-Ponce de León, Brooks & Daverdin, 2006 by having vitelline follicles that extend from a level anterior to the pharynx to mid-testes, the seminal vesicle which is more extensively folded, and a wider cirrus sac. The new species resembles Paracreptotrema heterandriae in the length of its ceca, which surpasses the posterior margin of the ovary but do not reach the testes. A key to the species of Paracreptotrema is provided.     

Seven new hypselostomatid species from China,including some of the world’s smallest land snails (Gastropoda,Pulmonata, Orthurethra)

Seven new species of Hypselostomatidae are described from the Chinese province Guangxi: Angustopila dominikae Páll-Gergely & Hunyadi, sp. n., Angustopila fabella Páll-Gergely & Hunyadi, sp. n., Angustopila subelevata Páll-Gergely & Hunyadi, sp. n., Angustopila szekeresi Páll-Gergely & Hunyadi, sp. n., Hypselostoma socialis Páll-Gergely & Hunyadi, sp. n., Hypselostoma lacrima Páll-Gergely & Hunyadi, sp. n. and Krobylos sinensis Páll-Gergely & Hunyadi, sp. n. The latter species is reported from three localities. All other new species are known only from the type locality. Specimens nearly identical to the type specimens of Angustopila huoyani Jochum, Slapnik & Páll-Gergely, 2014 were found in a cave in northern Guangxi, 500 km from the type locality. Adult individuals of Angustopila subelevata sp. n. (shell height = 0.83–0.91 mm, mean = 0.87 mm) and Angustopila dominikae sp. n. (shell height of the holotype = 0.86 mm) represent the smallest known members of the Hypselostomatidae, and thus are amongst the smallest land snails ever reported. We note that Pyramidula laosensis Saurin, 1953 might also belong to Krobylos. Paraboysidia neglecta van Benthem Jutting, 1961, which was previously included in Angustopila, is classified in Hypselostoma.     

Chaerilus pseudoconchiformus sp. n. and an updated key of the chaerilid scorpions from China (Scorpiones,Chaerilidae)

A new species, Chaerilus pseudoconchiformus sp. n., is described from Xizang, China. The present new species is distinguished from its congeners by a body length of 32−40 mm, carapace with the anterior margin straight, chela with length/width ratio average of 3.3 in males (3.2−3.4, two adults), and 2.5 in females (2.3−2.6, nine adults), eight or nine (eight usually) rows of denticles on fixed and movable fingers of pedipalp chelae, five pectinal teeth in males and three or four in females. To date, the chaerilid species fauna of China consists of nine species. An updated identification key to Chaerilus from China is presented.     

Description of Telamoptilia grewiae sp. n. and the consequences for the definition of the genera Telamoptilia and Spulerina (Lepidoptera,Gracillariidae, Gracillariinae)

The new species Telamoptilia grewiae, reared from leafmines on Grewia biloba (Malvaceae) is described with details on adult and immature stages. The larval head and the pupa are described for the first time in Telamoptilia Kumata & Kuroko, 1988, and are illustrated with scanning electron micrographs and line drawings. Photographs of adult habitus, wing venation, male and female genitalia, as well as host plant and mines are provided. The apomorphic adult and larval characters of the new species in Telamoptilia are discussed in relation to the recognition of the genera Telamoptilia and Spulerina Vári, 1961.     

A new species of the genus Baeoura from Morocco,with a key to the West Palaearctic species (Diptera,Tipuloidea, Limoniidae)

The genus Baeoura is represented in Morocco by two species, Baeoura ebenina Starý, 1981, and Baeoura staryi sp. n. The new species is described and illustrated, and a key to the West Palaearctic species of Baeoura is presented.     

A new species of Hemichela Stock, 1954 from the South China Sea (Arthropoda,Pycnogonida, Ammotheidae)

A new species of pycnogonid collected by the Chinese research vessel, R/V HY IV, during deep sea cruises to the South China Sea in 2013, is described. The new species, Hemichela nanhaiensis, obtained from more than 1300 m depth, is distinguished from the other two species in the genus by the characters of the chela dactylus with 12 denticulations on the inner margin and by the presence of taller tubercles on the lateral processes.     

A remarkable new Awas L?bl from southern China (Coleoptera,Staphylinidae, Pselaphinae)

A new distinctive species of the rare Oriental goniacerine genus Awas Löbl, Awas gigas sp. n., is described and illustrated, based on three males and fourteen females taken at the Daoyao Shan Natural Reserve in the southern Chinese province of Guangxi. All specimens were collected from colonies of the ant genus Pachycondyla F. Smith nesting in decomposing woods.     

The genus Pterostichus in China II: the subgenus Circinatus Sciaky,a species revision and phylogeny (Carabidae,Pterostichini)

All of the known species of the Chinese endemic subgenus Pterostichus (Circinatus) are revised, keyed, and illustrated. Eleven new species and one new subspecies are described: Pterostichus adelphus sp. n. (Sichuan: Meigu, N28.66°, E103.06°); Pterostichus ailaoicus sp. n. (Yunnan: Xinping, N23.94°, E101.50°); Pterostichus camelus sp. n. (Sichuan: Mianning, N28.97°, E102.16°); Pterostichus dimorphus sp. n. (Yunnan: Dayao, N26.08°, E101.03°); Pterostichus maitreya sp. n. (Guizhou: Fanjingshan, N27.90°, E108.70°); Pterostichus miao sp. n. (Guangxi: Maoershan, N25.87°, E110.41°); Pterostichus tumulus sp. n. (Guizhou: Fanjingshan, N27.90°, E108.70°); Pterostichus wangjiani sp. n. (Yunnan: Dongchuan, N26.08°, E102.87°); Pterostichus yan sp. n. (Hubei: Shennongjia, N31.47°, E110.39°); Pterostichus yuxiaodongi sp. n. (Sichuan: Wolong, N30.99°, E103.15°); Pterostichus zhygealu sp. n. (Sichuan: Meigu, N28.67°, E103.05°); and Pterostichus cavazzutianus mianningensis subsp. n. (Sichuan: Mianning, N28.97°, E102.16°). Pterostichus cavazzutianus is proposed as a replacement name for Pterostichus cavazuttii Allegro and Sciaky 2010, preoccupied by Pterostichus (Sinosteropus) barbarae cavazuttii Sciaky and Facchini 2003. A lectotype is designated for Pterostichus baenningeri Jedlička 1931. Two species, Pterostichus schuelkei Sciaky & Wrase and Pterostichus wenxianensis Allegro & Sciaky, are moved from the subgenus Circinatus to Morphohaptoderus. An infra-subgeneric taxonomy is proposed for the subgenus Circinatus with four species groups. The male endophallus characters for most species of Circinatus were well studied, with three types of endophallus defined. A phylogenetic analysis based on adult morphological characters confirmed the infra-subgeneric classification and clarified some of the relationships among species. Two main lineages within Circinatus were identified from the phylogenetic analyses. Three of the four species groups were monophyletic, whereas the fourth group was paraphyletic.     

Two new species and one new record of Parakiefferiella Thienemann, 1936 from China (Diptera,Chironomidae)

Two new species of the genus Parakiefferiella Thienemann, 1936 (Parakiefferiella fasciata Liu & Wang, sp. n. and Parakiefferiella liupanensis Liu & Wang, sp. n.) are described as adult males from China. Parakiefferiella tamatriangulata Sasa is recorded from China for the first time. A key to the known adult males of Parakiefferiella from China is presented. The generic diagnosis of male Parakiefferiella given by Cranston et al. (1989) is emended.
