Sticteulima Laseron, 1955


Sticteulima Laseron, 1955

Type species. Sticteulima cameroni Laseron, 1955 , by original designation, Recent; New South Wales, Australia .

Diagnosis. Shell small (1.5–4.0 mm), conical, straight or curved, vitreous and commonly with brownish/yellowish spots, spiral and/or axial bands; protoconch paucispiral or multispiral, whorls usually flat; teleoconch whorls slightly convex; umbilicus absent or an umbilical fissure present (adapted from Laseron 1955; Warén 1983; Mifsud & Ovalis 2019).

Remarks. MolluscaBase Eds. (2020d) included 16 species in Sticteulima . In the Atlantic Ocean, the genus is known from a few species that occur in the East Atlantic: Sticteulima badia ( Watson, 1897) , S. fuscopunctata (E.A. Smith, 1890) , Sticteulima lata Bouchet & Warén, 1986 , Sticteulima richteri Engl, 1997 , Sticteulima wareni Engl, 1997 ( Smith 1890; Watson 1897; Bouchet & Warén 1986; Engl 1997a, b). Only S. lata occurs in deep waters, but Bouchet & Warén (1986: 322) commented that this species “may ultimately prove to belong to more shallow water”, but they did not find material to corroborate this assumption. In the western Atlantic, several species of Sticteulima occur, but were never described or treated under this genus (personal observation).

Sticteulima badia is possibly a junior synonym of S. fuscescens .The holotype of S. badia (NMW 1955.158.00653) is severely damaged by Byne’s disease, which makes comparison difficult, but the shape, dimensions and color pat-tern is the same as the syntypes of S. fuscescens (NHMUK 1889.10.1.803–5).
