Taxon classification Animalia Stylommatophora Camaenidae

Amphidromus sinensis globosa Nevill, 1878 [nomem nudum, ICZN (1999: Art. 12)].

Amphidromus sinensis var. globosa Nevill, 1878: 126 [nomem nudum].

Type locality.

Chittagong [now in Bangladesh].

Type material.

Original specimen NHMUK 1903.7.1.1921 (1S, H=25.1 mm, W=16.5 mm).

Remarks.

The name " globosa ", an unavailable name, was included in this catalog in order to indicate the history of the taxon. This name was introduced without a description or indication and therefore failed to conform to the ICZN guidelines (1999: Art. 12) and could not be made available by Nevill (1878). Later, this name was cited in Pilsbry (1900: 191) and Richardson (1985: 44). They cited this name without vaidating the taxon, and so this name could not be made available in subsequent works (ICZN 1999: Arts 11.5.2, 12).

We have surveyed for Amphidromus in western Thailand and collected a number of specimens with similar shell morphology to Nevill’s (1878) original specimen. It appear to be an undescribed species, therefore, we provide a species description and description of genitalia anatomy as Amphidromus (Syndromus) globonevilli Sutcharit and Panha, sp. n. (see description below).
