revealed substantive morphological dissimilarities with both genera discussed above, particularly with unique structures of the male and female terminalia (see below). The new genus differs from them also in several external characters, particularly in having the dorsally flattened mesonotum, reduced thoracic chaetotaxy (prs, sa, ppl absent, pa short), both male and female with rows of shortened thickened setae on f 1 (anteroventrally) and f 3 (both anteroventrally and posteroventrally), C with distinct spine-like setae among fine setulae and very elongate slender abdomen. It is notable that some of these characters can be found as homoplasies in distinctly non-related genera, e. g. the flattened mesonotum in the genus
