Integrative taxonomic revision of the land snail genus Sarika Godwin-Austen, 1907 in Thailand, with descriptions of nine new species (Eupulmonata, Ariophantidae).

ABSTRACT: Members of the land snail genus SarikaGodwin-Austen 1907 are superficially similar and difficult to differentiate by their shell morphology so that their species limits are still unclear. In order to resolve the taxonomy of this group, a phylogenetic reconstruction of Sarika is presented, based on morphological and anatomical characters, as well as on partial sequences of the mitochondrial cytochrome c oxidase subunit I (COI) gene. In total, 23 species of Sarika are recognised in Thailand, and nine species are new to science, namely S. caligina Pholyotha & Panha, sp. nov., S. gratesi Pholyotha & Panha, sp. nov., S. inferospira Pholyotha & Panha, sp. nov., S. lactospira Pholyotha & Panha, sp. nov., S. megalogyne Pholyotha & Panha, sp. nov., S. melanospira Pholyotha & Panha, sp. nov., S. pellosa Pholyotha & Panha, sp. nov., S. solemi Pholyotha & Panha, sp. nov., and S. subheptagyra Pholyotha & Panha, sp. nov. Results from genital examination and COI analyses confirm the monophyly of Sarika and its species. The intra- and inter-specific genetic distances of Sarika were 0-3.7% and 4.6-12.0%, respectively. Colour images of the living adults, shell, and genitalia along with SEM images of the spermatophore and radula are given. In addition, an identification key and a geographical distribution map of Sarika species are provided.

A taxonomic note on the helicoid land snail genus Traumatophora (Eupulmonata, Camaenidae).

Project description:Traumatophoratriscalpta (Martens, 1875) is reported for the first time from the Tianmushan Mountains, Zhejiang Province, and its morpho-anatomy is described based on this new material. The genus Traumatophora is redefined on the basis of both shell and genital anatomy of its type species. The presence of the dart apparatus suggests this genus belongs to the subfamily Bradybaeninae rather than to the Camaeninae. This genus is distinguished from all other Chinese bradybaenine genera by the combination of the following key morphological characteristics: embryonic shell smooth, palatal teeth present, dart sac tiny with rounded proximal accessory sac that opens into a dart sac chamber, mucous glands well developed, entering an accessory sac through a papilla, epiphallic papilla absent, flagellum present. A comparison is also presented of Chinese bradybaenine genera with known terminal genitalia.

The first proven oxychilid land snail endemic to China (Eupulmonata, Gastrodontoidea).

Project description:A new and the first proven oxychilid species endemic to China is reported from Sichuan Province. Sinoxychilus gen. nov. is established based on this new species and has diagnostic traits of the sculptured protoconch, partial epiphallus wrapped by developed penis sheath, penial retractor muscle inserting on the top of penial caecum, spinelets on penial pilasters, absence of epiphallic papilla and perivaginal gland present on vagina and proximal bursa copulatrix duct. In light of shell morphology and through geometric morphometric analyses, Zonites scrobiculatus scrobiculatus Gredler and Z. scrobiculatus hupeina Gredler are proposed to be included in the new genus. A phylogenetic inference based on ITS2 gene indicates that the new genus is systematically close to Oxychilus Fitzinger, which is known from the Western Palearctic and the Southwestern Arabian Peninsula, regions that are geographically far from the distribution range of the new genus.

Jawless land snail Sinorachis, a new bradybaenine genus from China (Eupulmonata, Camaenidae).

Project description:A new land snail species that represents a new genus is reported from Hubei, China. The snail has a conical shell with pits and/or granules on embryonic whorls and a smooth teleoconch with straight peristome. The head of the animal has a developed wart. The mantle lobe is only developed on the left side. At the front of the buccal mass there is no chitinous jaw that is without exception seen in Chinese camaenids. Its radular teeth are usually slender and tongue-shaped, not typical in bradybaenine snails. The genital system is typical of Bradybaeninae and is characterized by the absence of a membranous sac surrounding the terminal genitalia, penial caecum or flagellum; a well-developed penis sheath; a symmetrical dart sac apparatus; and one distally branched mucous gland. The new species Sinorachis baihu Wu & Chen, gen. and sp. nov., is assigned to the type species of the new genus, in which all the known Chinese Rachis species are included. Thereby, the new genus is composed of three species, namely Sinorachis onychinus (Heude), comb. nov., Sinorachis aureus (Heude), comb. nov. and the new species.

Taxonomic revision of the Elephant Pupinid snail genus Pollicaria Gould, 1856 (Prosobranchia, Pupinidae).

Project description:The status of species currently assigned to the Southeast Asian Elephant Pupinid snail genus Pollicaria Gould, 1856 is reassessed. Shell, radular and reproductive morphology are investigated and analysed with reference to karyotype patterns previously reported and to distribution patterns among the species. Six previously described species are recognised: Pollicaria gravida (Benson, 1856), Pollicaria myersii (Haines, 1855), Pollicaria mouhoti (Pfeiffer, 1862), Pollicaria elephas (Morgan, 1885), Pollicaria crossei (Dautzenberg & d'Hamonville, 1887) and Pollicaria rochebruni (Mabille, 1887). A new subspecies, Pollicaria mouhoti monochroma ssp. n.,is proposed and a dichotomous key to species is provided.

Two new camaenid land snails (Eupulmonata) from Central China.

Project description:Two new camaenid land snails are reported from Central China. The new genus, represented by Sinochloritislii Wu & Chen, gen. & sp. nov., the type of the genus from Sichuan, is close to Yakuchloritis Habe, Nipponochloritis Habe, Neochloritis Minato and Trichochloritis Pilsbry, but is well characterized by the smooth adult shell, highly developed epiphallic papilla, absence of penial caecum, and the presence of an epiphallus-binding muscle that binds the proximal epiphallus to the distal penis. A new species Bradybaenalinjun Wu & Chen, sp. nov. is described from Hubei Province and is characterized by having two shell bands, a spoon-shaped love dart and the proportionally shortest mucous glands among Chinese congeners.

Revision of the Theopea genus group (Coleoptera, Chrysomelidae, Galerucinae), part III: Descriptions of two new genera and nine new species.

Project description:This publication treats species within Theopea and closely allied genera that were not covered in the previous two revisions. Three species of Theopea Baly, 1864 are treated herein, with T. bicolor Kimoto, 1989 and T. mouhoti Baly, 1864 redescribed, and T. bicoloroides sp. nov. described. A new genus that we consider closely related to Theopea, Pseudotheopea gen. nov., is described. This new genus can be recognized with the presence of reticulate microsculpture on the vertex of the head and pronotum and presence of an apical spine on each metatibia. The following species are transferred to Pseudotheopea as new combinations: Theopea aeneipennis Gressitt & Kimoto, 1963, T. azurea Gressitt & Kimoto, 1963, T. clypealis Medvedev, 2015, T. nigrita Medvedev, 2007, T. smaragdina Gressitt & Kimoto, 1963, T. similis Kimoto, 1989, and T. subviridis Medvedev, 2012. Theopea subviridis Medvedev, 2012 is regarded as new synonym of Pseudotheopea similis (Kimoto, 1989). In addition, six new species of Pseudotheopea are described: P. boreri sp. nov. from India, P. gressitti sp. nov. from Philippines, P. hsingtzungi sp. nov. from Laos, P. kimotoi sp. nov. from Laos, Thailand, and Vietnam, P. leehsuehae sp. nov. from Laos, and P. sufangae sp. nov. from Taiwan. A second new genus regarded as closely related to Pseudotheopea, Borneotheopea gen. nov., can be recognized by possessing uniform antennae in both sexes and lacking an apical spine on each metatibia. Two new species of Borneotheopea are described from Borneo: B. jakli sp. nov. and B. kalimantanensis sp. nov.
