Thaleia Warén, 1979

Type species. Benthonella nisonis Dall, 1889b , by original designation, Recent ; western Atlantic .

Diagnosis. Shell conical, medium length (5–9 mm), vitreous except protoconch; protoconch dark brown, slightly convex whorls, divided in protoconch I and II, protoconch I smooth, protoconch II sculptured by microscopic sinuous and denticulate axial lines and a straight spiral line close to the suture; teleoconch whorls slightly convex, deep suture, sculptured by microscopic axial lines; aperture short, outer lip very thin, umbilical fissure present (adapted from Warén 1979).

Remarks. Warén (1979) erected Thaleia as a monotypic genus with a doubtful classification, but related this genus to the Eulimidae . Since then, no additional data about the systematics of the genus is known and it is still allied to Eulimidae . MolluscaBase Eds. (2020e) include a second species in the genus, Thaleia mucronetincta ( Thiele, 1925) , from East Africa.
