Redescription.

Male. Carapace (Fig. 1A) bright yellow, long oval, widest at coxae II and III. Fovea circular, deep, its surrounding area reddish brown. Sternum light yellow, pear-shaped, the surrounding with seven gray circular patches, margin with long scopulae, median glabrous. AER slightly recurved, PER nearly straight, ALE and PLE contiguous. Chelicerae reddish brown, with 9 promarginal peg setae and 2 retromarginal teeth (Fig. 2C). Color of endites and labium similar. Legs spiniferous, femora with reddish brown patches. Dorsum of opisthosoma (Fig. 1A) suboval, light yellow-brown, with white patches on both sides, covered with long macrosetae. Venter grayish-white, with round white patches.

Male palp (Figs 1 B–C, 2 A–B): Patella strong, the dorsum with two thick and long macrosetae. Cymbium wedge, length/width ratio about 2/1, tip with several robust macro-setae Paracymbium distinct, distal black and strongly sclerotized. Distal division of the bulb rolls up as sulciform to protect embolus and serves as a functional conducter. Embolus relatively slender, distal division reaches the position of 2:00 o’clock approximately with a membrane covering its proximal area in prolateral view.

Female. Carapace (Fig. 3A) yellowish brown, pear-shaped, with several reddish brown diagonal patches, posterior margin reddish brown, fovea and sternum similar to male. ALE and PLE contiguous, AER and PER nearly straight. Endite, labium and sternum similar to male but darker. Chelicerae stronger than male with 12 promarginal peg setae and 2 retromarginal teeth (Fig. 4A). Legs femur with reddish annuli basely, other area with small reddish brown patches, patella brown, metatarsus with brown annuli. Opisthosoma (Fig. 3A) subcircular, slightly wider than long. Dorsum of opisthosoma (Fig. 3A) yellowish brown, with long macrosetae and white patches. The markings of venter similar to male. Spinnerets reddish brown, anterior spinnerets longest.

Epigyne (Figs 3 B–C, 4 B–C) slightly wider than long, with three parts, including lingulate scape, rectangular basal plate and a laminar layer covering the venter of the basal plate. Scape and basal plate cross shaped, scape about 1/2 length of Epigyne, width of basal plate approximately equal to Epigyne. Spermathecae ovoid, about 2/3 length of epigynum. Copulatory ducts indistinct in dorsal view.
