Spungisomyia Mamaev & Zaitzev, 1996

Introduced by Mamaev & Zaitzev (1996) for a single species, the genus Spungisomyia was recently shown to contain seven different species – six previously unnamed – in Sweden alone ( Jaschhof & Jaschhof 2013: 258 ff.). Our assumption then that there should be many more Spungisomyia awaiting discovery in Europe and other parts of the Palearctic ( Jaschhof & Jaschhof 2013: 258) has proven to be true: apart from two new species in Sweden described in the present paper, we now know of other unnamed species in Finland, Estonia, and South Korea. The two species in Sweden exhibit morphological structures that were previously unknown to occur in Spungisomyia ―clearly an indication that we have just begun to understand the intrageneric diversity. Also, there is no doubt any longer that the type species, Porricondyla media Spungis as perceived in previous literature (including Jaschhof & Jaschhof 2013), is in fact a complex of several different species. Males we have gathered over a number of years indicate the presence of three distinct media -like species in Sweden alone; those show subtle distinctions in the structure of both the gonostylus and aedeagal apodeme (unpublished data). A taxonomic revision of the media complex, which will take specimens from a broader geographic area into account, is in preparation.

According to the generic definition we published earlier ( Jaschhof & Jaschhof 2013: 258), Spungisomyi a is characterized by a set of male genitalic characters, as follows. Most importantly, the parameral apices usually are two- to multipointed, but, as shown here, may occasionally be single-pointed. Gonostyli are typically thick and subglobose, occasionally more elongate or flattened. Gonocoxal processes are either absent or present as inconspicuous, membranous projections on both sides of the ventral emargination. The apex of the aedeagal apodeme is covered by a membranous, sometimes slightly sclerotized cap, whose outline may be indicative of a species. Apart from genitalic traits, some species have bright, membranous windows on the scutum.
