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).
