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.
