Male (holotype). Total length 1.26; carapace 0.69 length, 0.54 width; abdomen 0.61 length, 0.33 width. Habitus as in Fig. 1A, C, E. Carapace: orange-brown, with brown egg-shaped patches behind eyes, oval in dorsal view, pars cephalica strongly elevated in lateral view, surface and sides strongly reticulate (Fig. 1B, D). Eyes: six, in one group, well developed, ALE largest, PME and PLE nearly equal sized; posterior eye row straight from above, procurved from front (Fig. 1G). Mouthparts: chelicerae slightly divergent, with a slightly sclerotized process at base of fangs (ssp) and two strong, thorn-like processes (tlp) in the middle of the retrolateral margin; fang groove with a few small denticles (Figs 1H, 3C). Anterior margin of labium not indented at middle. Anteromedian tip of endites with one strong, tooth-like projection (Fig. 1F). Abdomen: posterior spiracles not connected by groove. Pedicel tube short, unmodified, scutum extending far dorsal of pedicel. Dorsal scutum covering about 4/5 of abdomen, about equal to the abdomen width, not fused to epigastric scutum. Epigastric and postepigastric scutum well sclerotized, pale orange, fused. Leg spine formula: femur I with 2 prolateral and 1 small retrolateral spine, tibia I with 4 pairs, metatarsus I with 2 pairs of long ventral spines. Spination of leg II similar to leg I except femur with only one prolateral spine. Legs III and IV spineless. Genitalia: sperm pore situated at level of anterior spiracles. Palp strongly sclerotized, trochanter with ventral projection (vp); patella about as long as femur, not enlarged; cymbium brown, not fused with bulb, bulb brown, more than twice as long as cymbium, stout, tapering apically, with two small ventral protuberances (vpr), at the bending site with a membranous lobe (ml), distal part of bulb with membranous outgrowth (meo) (Figs 1I–K, 3A, B, D). Female (paratype). Total length 1.51; carapace 0.64 length, 0.52 width; abdomen 0.87 length, 0.56 width. Habitus as in Fig. 2A, C, E. As in male except as noted. Carapace: without any pattern, pars cephalica slightly elevated in lateral view (Fig. 2B, D). Mouthparts: chelicerae and endites unmodified (Fig. 2F). Abdomen: dorsal scutum covering about 2/3 of abdomen, about 1/2 of abdomen width. Postepigastric scutum elongated hexagonal, not fused to epigastric scutum, with short posteriorly directed lateral apodemes (a) (Fig. 2G, H, J). Genitalia: at the middle of the anterior edge of the postepigastric scutum runs a dark, strongly winding tube posteriorly (wt), ending in a large goblet-like atrium (gla) close to posterior edge of scutum (Fig. 2I, K).
