Type material.

Holotype ♂ (IZCAS-Ar42904), China: Yunnan: Xishuangbanna, Mengla County, Menglun Town, Xishuangbanna National Nature Reserve, 200 m east of Lvshilin, artificial forest (21°57.95'N, 101°12.30'E, ca 780 m alt.), 13.viii.2011, Q. Zhao leg. Paratypes 2♂7♀ (IZCAS-Ar42905-42913), same data as holotype; 1♂2♀ (IZCAS-Ar42914-42916), 55 km from Xishuangbanna National Nature Reserve, secondary forest (21°57.99'N, 101°12.17'E, ca 840 m alt.), 18.viii.2011, Q. Zhao leg.

Etymology.

The specific name is a patronym in honor of Qingyuan Zhao, the collector of this new species; noun (name) in genitive case.

Diagnosis.

Bocusoides zhaoi sp. nov. closely resembles B. angusticollis comb. nov. from Borneo in having a similar habitus and copulatory organs, but it can be easily distinguished by the following: 1) width of embolic disc greater than largest diameter of visible sperm duct (Fig. 1D ) versus less than 1/2 in B. angusticollis ( Deeleman-Reinhold and Floren 2003: fig. 13); 2) RTA curved inward distally in ventral view (Fig. 1D ) versus curved retrolaterally in B. angusticollis ( Deeleman-Reinhold and Floren 2003: fig. 13); 3) tibial flange about 1/4 RTA length in dorsal view (Fig. 1E ) versus more than 1/2 in B. angusticollis ( Deeleman-Reinhold and Floren 2003: fig. 14); 4) male chelicerae with three distal promarginal teeth that are almost equal in size, and female chelicerae with six promarginal teeth (Fig. 2G, H ) versus male chelicerae include a basal denticle among the three distal promarginal teeth and female chelicerae with only three promarginal teeth in B. angusticollis (see the description by Deeleman-Reinhold and Floren 2003); 5) copulatory ducts partially encircle spermathecae (Fig. 2B ) versus copulatory ducts lateral to spermathecae in B. angusticollis ( Deeleman-Reinhold and Floren 2003: fig. 17).

Description.

Male (Figs 1 , 2C-E, G ). Total length 5.00. Carapace 2.68 long, 1.23 wide. Abdomen 2.00 long, 1.23 wide. Clypeus 0.03 high. Eye sizes and inter-distances: AME 0.37, ALE 0.19, PLE 0.17, AERW 1.06, PERW 1.06, EFL 0.89. Legs: I 4.88 (1.45, 1.98, 0.90, 0.55), II 4.15 (1.30, 1.60, 0.80, 0.45), III 4.96 (1.55, 1.68, 1.23, 0.50), IV 6.52 (2.13, 2.23, 1.63, 0.53). Carapace elongated, yellow to yellow-brown, covered with dark brown setae at anterior margin, elevated cephalic region and sloped thorax separated by deep constriction. Pedicel short, with dorsal, conical process. Chelicerae broad, with five promarginal and six retromarginal teeth. Endites longer than wide, bearing dense, dark setae distally. Labium slightly darker than endites. Sternum elongated, irregular, about 2.5 times longer than wide. Legs yellow to dark brown, with 11 and five ventral spines on tibiae and metatarsi I, respectively. Abdomen suboval, dorsum with yellow-sliver spots separated by a longitudinal, central, vein-shaped, brown band anteromedially, followed by alternate dark and dark yellow transverse bands, entirely covered by scutum; venter dark brown.

Palp (Fig. 1A-E ): tibia wider than long in ventral view, with short, triangular flange, tapered retrolateral apophysis slightly curved into an S-shape at distal half, pointed apically; cymbium flat, setose, with apical bristle; bulb flat, almost round, with tapered sperm duct; embolus twice coiled, the first forming a broad, flat circle, the second with elongated, lamellar disc followed by filiform remainder coiling about 360° and reaching cymbial tip distally.

Female (Fig. 2A, B, F, H ). Total length 5.59. Carapace 2.68 long, 1.09 wide. Abdomen 2.46 long, 1.50 wide. Clypeus 0.03 high. Eye sizes and inter-distances: AME 0.38, ALE 0.19, PLE 0.17, AERW 1.06, PERW 1.05, EFL 0.83. Legs: I 3.81 (1.18, 1.53, 0.65, 0.45), II 3.33 (1.05, 1.30, 0.60, 0.38), III 4.23 (1.35, 1.43, 1.00, 0.45), IV 5.69 (1.80, 1.98, 1.43, 0.48). Habitus similar to that of male except with less-developed chelicerae with six promarginal and seven retromarginal teeth, a pair of white spots on the lateral margins of carapace constriction, without scutum on dorsum of abdomen.

Epigyne (Fig. 2A, B ): slightly longer than wide, with tube-shaped, posteriorly located hood; atria paired, oval, extending transversely, with arched lateral ridges; copulatory openings hidden; copulatory ducts membranous at origin, followed by sclerotized portion ascending obliquely, coiled four times distally; spermathecae elongated, partly encircled by copulatory ducts; fertilization ducts slender, arched, originating from the anterior portions of spermathecae.

Distribution.

Known only from the type locality in Yunnan, China.
