Dense patch of setae anterior to spinnerets absent. Interscutal membrane with setae. Colulus present, small, sclerotized colulus sporting two hairs. Spinnerets: ALS: aLS two-segmented, with one major ampullate gland spigot and three piriform gland spigots, the anterior one clearly separated from the two posterior ones; PMS: pMS single-segmented, digitiform, with only one spigot; PLS: pLS two-segmented, with three spigots. LEGS: femur IV not thickened, same size as femora I-III, tibia I unmodified, metatarsi I and II meso-apical comb absent, coxae leg formula 4123. Legs white with parts of some segments dark brown, giving legs banded appearance. Leg spines absent. Tarsi I to IV superior claws tooth examined in detail. Tarsi I to IV without inferior claw. Trichobothria examined with SEM; tibia: each with three; metatarsus: each with one; aperture internal texture grate-like, hood covered by numerous low, closely spaced ridges, each leg with four dorsal trichobothria: one on proximal tibia, two on distal tibia, one on distal metatarsus. Articulating membrane ridged. No variation in bothrium structure among legs or among positions on a given leg. Tarsal organ tarsal organ similar on all legs, exposed. GENITALIA: Epigastric region with sperm pore small, situated at level of posterior spiracles; furrow without setae. Palp not strongly sclerotized, right and left palps symmetrical; embolus prolateral excavation absent, bulbus with distal embolus and conductor. Embolus tubular but tip flattened, opening to outside via broad slit. Tip often bent at almost 90° angle. A small projection present near embolar tip. Conductor slender, usually broader at base; situated approximately prolaterally of embolus; trochanter unmodified; femur two or more times as long as trochanter, attaching to patella basally; patella shorter than femur, not enlarged, without prolateral row of ridges, setae unmodified; tibia tibia as long as patella, trichobothria with 3 trichobothria; cymbium fused with bulb but with clearly defined seam between, extending beyond distal tip of bulb, with distal patch of setae, tarsal organ tarsal organ situated medially on cymbium; structure as on legs; bulb shorter than cymbium.
