Taxonomical notes on Chinese camaenids with description of three new species (Gastropoda: Pulmonata)
2018
The present study deals with four Chinese camaenid species based on museum collections and newly obtained materials. Pseudiberus liuae Wu, n. sp., diagnosed by two long mucous glands and the smallest shell size in the genus and inhabiting bare rock like other congeneric members, is described from southern Gansu. Aegista (Plectotropis) wardi (Preston, 1912) is conchologically re-described and moved out of Aegista Alber, 1860 to Pseudiberus Ancey, 1887 based on the keeled periphery and the absence of hairs, scales or their scars on the teleoconch, which are present in Aegista but partially absent in Pseudiberus. The first Chinese fluorescent snail Bradybaena qixiaensis Wu & Asami n. sp. is reported from Nanjing, Jiangsu. The species shares many characters with the Japanese fluorescent snail Bradybaena pellucida Kuroda & Habe, 1953 but is distinct in the pattern of microsculpture on the internal surface of the penis. Nesiohelix yeni Wu & Asami n. sp., sympatric with N. moreletiana (Heude, 1882), is distinguished from its congener by possession of a bubble-shaped penial caecum.
