Revised diagnosis

Female inner spermathecae consist of long finger-like sacs that branch close to the copulatory tube end, similar to in H. hahni except that the finger-like tubes are longer and thinner ( Figs 6–8 ). Male embolus consisting of a thin pointed apical part and straight-sided thicker basal section ( Fig. 17 ), similar to in H. hahni except for the longer thin apical part in relation to the thicker basal part.
