Laevaricella perlucens

[1] Laevaricella perlucens is very restricted in range[2] and probably meet the IUCN-criteria of Critically Endangered species.

Testa subulate-turrita, laevis, diaphana, fusco-flavida, vix striatula, lineis distautibus ornata; apex obtusissimus; anfractus 7, parum convexi, lente accrescentes, ultimas applanatus, spirse longitudinem circiter sequans; sutura valde impressa; columella valde torta, truncata; peristoma simplex, margine externo aliquanto prominente.

A subulate-turreted, smooth, brilliantly polished, yellowish-red shell, marked by obscure striae and by distant variciform lines, of which there are from three to six on a whorl; with a very obtuse apex and seven slowly increasing, scarcely convex whorls, the last somewhat flattened and equal to about half the length of the shell; columella strongly curved, truncate; aperture oval, elongate; peristome simple, its external margin somewhat prominent.

Of three examples I obtained, one only was of full growth.This species had never been collected since it was described by Guppy (1868)[1] until 2009 and his type material was subsequently lost.

[2] It does not occur, however, on the upper slopes of the higher peaks, but it seems to be restricted to the hygrophytic vegetation zone (cloud forest).
