On the genus Tripselia and the group of Basilia bathybothyra (Nycteribiidae, Diptera)

Abstract

Some species of Nycteribiidae have been recorded from widely different faunistic regions. Thus, Eucampsipoda hyrtlii has been recorded from Africa, Ceylon, Burma and Sumatra. Other species have been recorded from Europe and China or from Europe and South Africa. Re-examination of the material has proved in most cases that the species were wrongly identified and no species has been found so far to exist both in Europe and in East Asia. There remained finally two species which have been recorded from the Ethiopian and the Oriental region, Tripselia blainvillii and Basilia bathybothyra. Material of these two species from as many localities as possible was therefore brought together, in order to determine whether this wide distribution does in fact occur or whether, in these cases as well, there existed different forms, species or subspecies, with a narrower range of distribution.
