Punctations are numerous but shallow with irregular size and distribution. Genital
aperture is situated between coxa III.
Legs: Legs are long and robust. Each coxa bears a moderate spur, while trochan-
ters I to III show small spurs or ridges.

Related Species 52
H. aponommoides and phylogenetically primitive H. inermis are closely related
species. These two species differ between themselves and widely from all other
haemaphysalids by following characters. The female palpi of H. aponommoides are
more narrowly elongate than those of H. inermis. In H. inermis females, palpi are
approximately 1.5 times as long as the basis capituli; in H. aponommoides females
they are slightly over twice as long as the basis capituli. Cornua, which are absent
or very slightly suggested in H.
inermis females, are short but distinct
