In this paper we provide an overview of the genus Laeocathaica after consulting all available types and newly collected samples. filippina (see Wu 2004), providing little basis of our understanding of the systematics of Laeocathaica and related genera. prionotropis (see Chen and Zhang 2004), L. The genital anatomy is known in a handful of species only: L. Some are large, with a white base colour, keeled or rounded body whorl, and without apertural barriers, others are keeled with apertural barriers, and some are small, transparent, and also possess apertural teeth. Second, the genus Laeocathaica as understood by Möllendorff (1899) and Chen and Zhang (2004) is variable in terms of shells characters. Moreover, species similar to Laeocathaica species (e.g., Bradybaena haplozona Möllendorff, 1899) have been classified in genera different from Laeocathaica ( Möllendorff 1899 Chen and Zhang 2004). Pfeiffer, 1850 from Japan, which makes it questionable that the same large-bodied land snail genus could inhabit such a vast area covering ca. The type species of the latter is Helix peliomphala L. First, Laeocathaica is defined by the sinistral shell coiling, whereas species with dextral shells of otherwise similar appearance (large, depressed shells with white base colour and brownish spiral bands) are included in other genera such as Cathaica Möllendorff, 1884, Bradybaena Beck, 1837, and Euhadra Pilsbry, 1890 ( Chen and Zhang 2004). The monophyly of this genus is questionable for several reasons. filippina (Heude, 1882) is known from Hubei Province, more than 500 km southeast from southern Gansu. Most of the species assigned to this genus were reported from the southern part of Gansu Province and the neighbouring Sichuan. The genus Laeocathaica Möllendorff, 1899 consists of approximately 20 species, and inhabits west China.
