Two of the character states he elaborated are hardly significant because they are based on the partly incorrect or incomplete description of Koenike's species: In both species, (1) setae are located all over the coxal surfaces and not restricted to the lateral edge, (2) setae on genital flaps are not restricted to the posterior edge, but arranged in multiple rows ending posterior to the anterior flap margin.
