Nephropores, after the first few segments, alternate regularly between c and b lines with anterior segmental distributions: 37c, 8 c or b, 910c, 11b, 12c, 13b, etc. Spermathecal pores in mid-ab lines in 7/8 and 8/ 9. Female pores faint, just anterior to b setae on 14. Prostatic pores approximately in a lines on 17 and 19 with protuberant penial setae. Male pores not located within concave seminal grooves, although likely central between retained ab setae. Genital markings absent, but setae ab on 16 with slight pale tumescence as on 20lhs. Genital setae absent; penial setae longish, curving with spoon-shaped tips [one of their functions, if not primary function, is to scrape out or disrupt any prior semen from spermathecal diverticula that often correspond in depth to the setal length (see Blakemore 2000)].

due to its alternating nephridiopores, this species appears unique in its lack of dorsal pores (although more information is needed on several other congeners), gizzard in 6, lack of oesophageal glands, and genital marking absence. Multiloculate spermathecae appear characteristic of the genus and in the current species their form is almost identical to
