Stephanopis pustulosa (informal)

This spider is a cryptic species, usually found on the bark of trees, its surface colours matching those of the bark. Females 7-12mm, males 4-6 mm. The head is narrowed to a snout with eyes in this genus is almost Poltys-like. To determine Stephanopis species it seems you should look at the knobbles on the carapace and the femurs of leg I. S. pustulosa seems to have two semicircles of three or more knobbles on either side of the carapace in the shoulder region, a "road narrows ahead" mark on the abdomen and fairly nondescript spines on the legs. S. corticalis seems to lack the shoulder knobbles and has distinct leg knobbles. The epithet corticalis should mean radiating spokes.
