Abiskomyia paravirgo Goetghebuer

Abiskomyia paravirgo Goetghebuer, 1940: 70 , Fig. 21 , 1940–1950: 206; Thienemann 1941: 205, 1944: 563; Langton & Visser 2003: 236; Ashe & O’Connor 2012: 109.

Remarks. This species was very briefly described on the basis of a single adult male (Goetghebuer 1940), and later nobody has investigated holotype which was apparently lost (Spies, pers. comm.). More comprehensively were described pupa and larva ( Thienemann 1941; Langton & Visser 2003).

In the original description of male there is no information on very important characters in diagnostic, namely the location of the acrostichal setae of scutum. But there is evidence of the presence of megasetae in gonostylus, which is absent in all other species of the genus. Main features of pupa and larva of this species are similar or may be the same to A. levanidovi . However, in this paper we cannot discuss the degree of relationship and possible synonyms of A. paravirgo and A. levanidovi because of the inability of detailed study of the adult male of A. paravirgo .

Distribution. In our opinion A. paravirgo is known only from the type locality in the Abisko area of the Swedish Lapland (Goetghebuer 1940; Thienemann 1941), and all references to this species from other regions are doubtful.
