Erhaia banepaensis Nesemann & S. Sharma, 2007 Fig. 8

Erhaia banepaensis Nesemann & S. Sharma, in Nesemann et al. 2007: 64 ("Nepal, Central Zone, Kavre District, small forest stream, left tributary of the Chandeswari Khola upstream from Chandeshwari at Banepa"; the altitude is not indicated).

Shell.

The shells are described by Nesemann and Sharma (2007: 64) as 1.6-2.0 mm high, with 4- 4½ “convex” whorls, an aperture that is "ovate but not widened and not enlarged", with an inner lip that is "thin and fused to the body whorl"; it can be distinguished from the other Nepalese Erhaia species by the "conical and compact shape" and “convex” whorls (2007: 65).

Material examined

(photo only). Holotype. (NHMW 1033159).

Notes.

Nesemann and S. Sharma are mentioned as authors for this species, without specifying for what part of the text in Nesemann et al (2007) they have responsibility.

According to Nesemann et al. (2007: 64) E. banepaensis occurs sympatrically with E. chandeshwariensis at the shared type locality of these species. Erhaia banepaensis is supposed to be more widely distributed in Nepal between 1400 and 2085 m a.s.l., but the type series is restricted to the holotype (NHMW 103319 [not 1033159]) and a paratype (NHMW 103320). The location of the additional material is not indicated.
