description: Copuetta kwamgumi sp. nov.
Figs 46, 47, 101, 120–123
Etymology: The species name is a noun in apposition of the type locality.
Diagnosis: This species is closely related to C. erecta sp. nov. Males can be recognised by the tiny embolus with tip directed distally, which is the smallest in the genus (Fig. 101), while that of C. erecta sp. nov. is clearly longer and straight, with the tip directed distally (Fig. 100). Females are characterised by the small lateral commashaped sclerotised rims that surround the round copulatory openings (Fig. 122), which differ from the small, coiled ridges of C. erecta sp. nov. (Fig. 116). Furthermore, C. erecta sp. nov. females have large semi-circular peripheral ridges in the posterior half of the epigyne that are absent in C. kwamgumi sp. nov.
