Chalcoscirtus lii Lei and Peng 2010: 67, fig. 1A-C (female holotype, not examined).

Material examined.

1♂ 1♀ (IZCAS-Ar42917-42918), China: Yunnan: Xishuangbanna, Mengla County, Menglun Town , Menglun Nature Reserve , Xishuangbanna Tropical Botanical Garden , 1 site in Mafengzhai (21°53.49'N, 101°17.40'E, ca 520 m alt.), 29.iv.2019, C. Wang leg.

Diagnosis.

The male of this species closely resembles that of C. vietnamensis ( Żabka, 1985) from Vietnam in having a similar palp, but it can be distinguished by the following: 1) embolus with small, semicircular lamellar process (Fig. 3B ) versus with a larger, subtriangular process in C. vietnamensis ( Żabka 1985: fig. 71); 2) RTA broadened and extending anteriorly at distal half (Fig. 3C ) versus somewhat tapered, extending antero-prolaterally in C. vietnamensis ( Żabka 1985: fig. 72). The female of this species resembles that of Chalcoscirtus parvulus Marusik, 1991 from Greece, Turkey, Kazakhstan, Iran, and Central Asia in having paired, oval atria and straight, short copulatory ducts, but it can be easily distinguished by the following: 1) spermathecae separated by more than 2/3 their width (Fig. 4A, B ) versus touching in C. parvulus ( Logunov and Marusik 1999: fig. 93); 2) abdomen dorsally with a longitudinal, fusiform stripe across entire surface (Fig. 4E ) versus with a pair of bars posteriorly in C. parvulus ( Logunov and Marusik 1999: fig. 91).

Description.

Male (Figs 3 , 4C, D, F, G ). Total length 4.23. Carapace 2.30 long, 1.77 wide. Abdomen 2.24 long, 1.53 wide. Clypeus 0.11 high. Eye sizes and inter-distances: AME 0.49, ALE 0.31, PLE 0.25, AERW 1.50, PERW 1.53, EFL 1.27. Legs: I 6.71 (2.00, 2.95, 1.23, 0.53), II 5.03 (1.53, 2.00, 1.05, 0.45), III 4.21 (1.33, 1.48, 0.95, 0.45), IV 4.46 (1.40, 1.60, 1.01, 0.45). Carapace dark brown, bearing bilateral white and antero-marginal dark setae. Fovea dark, longitudinal, bar-shaped. Chelicerae red-brown to dark, with two promarginal teeth and one retromarginal fissidental tooth with two cusps. Endites paler than chelicerae, with pale ental margins bearing dark, thin setae. Labium dark. Sternum colored as labium, almost heart-shaped, bearing dark setae. Legs I longest, dark brown except tarsi red-brown, with three and two pairs of ventral spines on tibia and metatarsi, respectively; rest of legs yellow, with dark brown femora. Abdomen suboval, dorsum dark brown, with longitudinal, yellow to dark brown fusiform stripe across entire surface, cluster of antero-marginal white setae; venter brown, with pair of rufous, oblique stripes medially, covered with dark, thin setae.

Palp (Fig. 3A-C ): tibia thick, slightly longer than wide; retrolateral tibial apophysis narrowed medially, broadened, extending anteriorly at distal half; cymbium almost two times longer than wide, gradually narrowed at distal half in ventral view; bulb suboval, with sperm duct sinuous retrolaterally; embolus short, originating from antero-prolateral portion of bulb, blunt apically, with small, semicircular lamellar process at base.

Female (Fig. 4A, B, E ). Described by Lei and Peng (2010).

Distribution.

Known only from the type locality in Yunnan, China.
