Diagnosis
Females of S.kolpogaster are similar to those of S.lucida by the general shape of the spermathecae, short copulatory ducts, and femora I with two mesial macrosetae. However, females of S.kolpogaster can be easily distinguished from congeners by curved tibiae I and II, flattened prosoma, dark body colouration, varying from dark-brown to black and contrasting with their vivid yellow legs III and IV (Fig. 8A). The males can also be recognized by their body colour pattern, which is the same as in females, and by their truncated RTA fused with basal branch (Fig. 9D, F).
Description
Female: Prosoma dark-brown, lighter on the ocular area and clypeus, covered by hyaline setae and dorsoventrally compressed (Fig. 8B). legs I and II entirely dark-brown, except for the reduced and yellowish tarsi; metatarsi I and II curved; legs III and IV entirely light-yellow (Fig. 8A). Opisthosoma dark-brown with posterior projections stout and conical. Epigynal plate wide and with short septum; copulatory ducts short and hyaline (Fig. 8C–F).
