Type material.
Holotype
: Kopanedza, coll. Godwin-Austen, NHMUK 20191131 (D: 15.4 mm, H: 8.1 mm).
Diagnosis.
Shell small, with slightly elevated spire; periostracum thick, brown, hair scars (truncated hairs or strawberry seed-like scars) extremely sparsely arranged on the body whorl; aperture oval, almost rounded.
Description.
Shell small; depressed-globular, with very slightly elevated spire (low domed dorsal side); body whorl rounded; colour brown due to thick, matt (dull) periostracum, locally worn locally making the nude whitish shell surface visible; protoconch consists of 1.5 whorls, finely wrinkled, with hair scars reminiscent of strawberry seeds; entire shell consisting of 4.25 whorls, suture moderately deep; inside of umbilicus and suture with mamilla-like, relatively densely arranged hair scars; other parts of teleoconch with extremely widely-spaced hairs (truncated, reddish-brown hairs or strawberry seed-like scars, and very few, relatively long, conical hairs); aperture oval, almost rounded; peristome strongly expanded and slightly reflected in direction of umbilicus; palatal part with a very thin, whitish, semi-transparent layer, which allows hair scars of the penultimate whorl to be seen; umbilicus open, narrow, funnel-shaped, peri-umbilical keel blunt.

Bouchetcamaena raripila
Pall-Gergely
sp. nov., holotype (NHMUK 20191131). For positions of close-up images see Fig.
6
(F = DM, G = CA, H: LV, I: PC).
Measurements.
D = 15.4 mm, H = 8.1 mm (n = 1).
Differential diagnosis.
Differs from
B. procumbens
by having a more rounded shell shape and the last whorl is also more rounded. Most important are the extremely widely-spaced and prominent hair scars. This latter trait distinguishes
B. raripila
sp. nov. from all other similar species.
Etymology.
The name
Bouchetcamaena raripila
refers to the few hairs/hair scars on the shell surface (
rarus
: few,
pilus
: hair in Latin).
Distribution.
The new species is known from the type locality only. Kopanedza (also spelled Kopamedza) is situated in the Barail Range, Dafla Hills (India), although its exact locality is unknown (
Pall-Gergely
et al. 2015b
).
