Discussion. The species was described from Greenland ( Rübsaamen, 1898), and redescribed and illustrated by Menzel & Mohrig (2000), with the discussion of the type material. Trichocoelina cochleata is characterized by having a medially impressed gonostylus, with a strongly curved apical part. The antennal scapus and pedicellus as well as the hypopygium and legs are yellow, but the apex of gonostylus has strikingly dark setosity. The gonostylus bears 6–7 rather long and slender gonostylar megasetae, the tegmen is broadly subconical with a sclerotized dorsoapical process. The intergonocoxal lobes of the hypopygium are short. For similar species, see under Trichocoelina aemula sp. n. and T. semusta sp. n.
