Diagnosis. The male palp of this species is similar to that in E. subtilis described below, but the embolus is longer and thinner. These species also differ in the coloration of the abdomen (light with dark streaks in E. nana , uniformly dark in E. subtilis ).

Etymology. The specific name is Latin, referring to the small size of the body.

Description. Measurements (male). Cephalothorax: length 1.0, width 1.1, height 0.8. Abdomen: length 1.5, width 1.1. Eye field: length 0.7, anterior width 1.1, posterior width 1.0.

Male. General appearance as in Figs 90, 91 , small, light coloured spider. Carapace oval, brown with yellow median stripe extending from posterior median eyes to posterior rim of carapace, black rings around eyes. Dorsum covered with white hairs, denser on anterior part of eye field. Clypeus and chelicerae yellowish brown. Clypeus clothed in sparse white hairs and brown bristles, with long, upward-bent bristles in the middle part. Chelicerae as in Fig. 92 . Sternum yellowish brown. Dorsum of abdomen light, whitish yellow with two longitudinal brown stripes ( Fig. 90 ), sides white. Abdomen yellow ventrally, with brown median streak, brown stripes on sides ( Fig. 91 ). Book-lung covers greyish yellow. Spinnerets brownish yellow. Femora of all legs light yellow, dark-brown spot prolateraly at distal end of femora I. Patellae and tibiae and metatarsi I brown, ventrally dark brown. Patellae, tibiae, metatarsi and tarsi of II–IV legs yellowish brown. Pedipalps yellow, only femora brownish. Embolus thin and long, its basal loop hidden in shallow hollow on the tip of bulb ( Figs 93, 95 ).

Female unknown.

Distribution. Known only from type locality.

Remarks. Only the right palp is present in the holotype, mirror images of the copulatory organ are given in the figures to match the left palps shown in the other species.
