ABDOMEN: dorsum soft portions yellow-reddish ground color with dark purple net-like pattern, cardiac mark pale, posteriorly with two posteriad pale lines. Book lung covers connection of posterior spiracles by distal rim of postepigastric sclerite. Pedicel scutum not extending far dorsal of pedicel. Dorsal scutum absent. Epigastric scutum small lateral sclerites present, without lateral joints.

Colulus small plate with 2 setae. Spinnerets: ALS: anterior lateral spinnerets bisegmented, basal segment without oblique membranous strip, with one major ampullate gland spigot and two (unsure) piriform gland spigots; PMS: posterior median unisegmented, with six spigots; PLS: posterior laterals bisegmented, with ten spigots. LEGS: orange-brown; tibiae emerit's glands not examined, tarsi pairs of special setae with distinct flattened clawlike apexes present on tarsi III, IV. Leg spination (only surfaces bearing spines listed, all spines longer than segment width): femora: I p0-1-1; II p0-0-1; tibiae: I p1-0-0; v4-2-2; II v4-2-1p; IV p0-1-0; v0-0-1; r0-1-0; metatarsi: I v2-2-2; II p1-0-0; v2-2-2; IV p0-1-0.
