Description

Male. Measurements (in mm): Body length 1.28; carapace 0.70 length, 0.55 width; abdomen 0.85 length, 0.60 width. Leg measurements: I 2.03 (0.61, 0.29, 0.48, 0.40, 0.25), II 1.76 (0.60, 0.16, 0.55, 0.25, 0.20), III 1.65 (0.55, 0.22, 0.36, 0.34, 0.18), IV 1.69 (0.59, 0.25, 0.34, 0.30, 0.21). Leg formula: 1> 2> 4> 3.

Cephalothorax. Carapace and sternum yellow; legs and abdomen pale yellow; chelicerae brownish-yellow. Sides of carapace with finely longitudinal striae; dorsal area smooth with some mesially pointing hairs at lateral edges. Eyes six in two rows, rather large, nearly equally-sized; posterior eyes in a straight row, touching each other (Fig. 2 A). Base of fang without ornament (Fig. 2 C). Labium wider than long, endites with membranous tips (Fig. 2 B).

Legs. Leg with distinct hairs: femur with a row of short ventral setae, 2 prolateral setae; patella without setae; tibia with 2 prolateral setae, 1 retrolateral seta and 1-2 trichobothria; metatarsus with 2 long dorsal setae.

Abdomen. Dorsal scutum oval-shaped, covering nearly whole abdomen. Lobes on anterolateral corners of petiolar tube distinct, ridges developed, but without forming a scutal cove.

Male palp. Palp (Fig. 3 A, B) minute, strongly sclerotised. Palp cymbium dark yellow, bulb dark yellow. Palp trochanter normal, with ventral projection. Palpal patella shorter than femur, not enlarged, unmodified. Palp cymbium narrow in dorsal view, cymbium and bulb incompletely fused, with seam visible in retrolateral view, covered with setae. Bulb of palp elongated, gradually tapering apically, obtusely bent before apex. Embolic part not divided into distinct lobes, bearing some membranous outgrowths.

Female. As in male, except as noted. Slightly larger than male. Measurements (in mm): Body length 1.34; carapace 0.65 length, 0.50 width; abdomen 1.00 length, 0.70 width. Leg measurements: I 1.61 (0.55, 0.20, 0.36, 0.28, 0.22), II 1.61 (0.50, 0.26, 0.34, 0.31, 0.20), III 1.43 (0.45, 0.18, 0.33, 0.30, 0.17), IV 1.91 (0.55, 0.28, 0.44, 0.39, 0.25).

Epigynum. Genital area with a small knoblike projection, most of which showing inverted V-shaped ridges (Fig. 2 D), a few are inverted Y-shaped. Two internal apodemes rise from the anterior border of post epigastric furrow; a strongly-twisted duct runs from the anterior border of the postepigastric furrow ending in the middle of the knob-like projection (Fig. 2 E).

Distribution

America, Australia, China (new record), Gambia, India, Indonesia, Pakistan, Pacific Is., Philippines, Seychelles, Sierra Leone, Sri Lanka, Yemen.
