Abstract

The sinistral Camaena species are mainly distributed in southern China and northern Vietnam. There is a total of eight species or subspecies of sinistral Camaena recorded at present. By systematically collecting specimens in Guangdong, Guangxi and Yunnan in southern China and the northern areas in Vietnam, two new species, Camaena lingyunensis Zhou & Lin, sp. n. and Camaena detianensis Zhou & Lin, sp. n. have been discovered. These new species are here characterised based on the comparison of shells, their reproductive system, the molecular phylogenetic analyses of the mitochondrial genes COI and 16S, and the nuclear gene ITS2. Detailed descriptions of the morphological characters, the DNA sequences, and the habitat of the two new species are given. Differential comparisons with related species are provided as well as a key to the sinistral species of Camaena.
