The combination of a little modified penial setae, with slightly proximal nodulus, the slit-like spermathecal pores, with well-developed vestibulae and without tegument thickening, the sacciform atria, with large lumen and thick muscular layer, and the conical, elongated penes as a simple extension of the atrial lining cells clearly distinguishes this species among all its congeners.

These morphological modifications, in association with reduced accessory copulatory glands, justify setae in the male segment being considered as genital, namely penial, setae. In this respect,
