Description
During the identification and sorting of German Sciaridae as part of the GBOL III "Dark Taxa" project, it was noted that specimens identified as Bradysia polonica (Lengersdorf, 1929) displayed such morphological variation that they could potentially be split into at least two morphospecies. An integrative taxonomic approach, utilising molecular and morphological data, confirmed the presence of two species, with one species being identifiable as Bradysia spinidensa Hondru, 1968, a species previously synonymised under B. polonica.
Using an integrative taxonomic approach combining molecular and morphological data, the observed morphological variation of Bradysia polonica (Lengersdorf, 1929) was investigated. The molecular data combined with the morphology of the gonostyli confirmed the presence of two species, with Bradysia spinidensa Hondru, 1968 being reinstated as a valid species.
