Leclercera xiaodai sp. nov. Figs 29 View Figure 29 , 55A View Figure 55 , 58 View Figure 58

Types.

Holotype: ♀ (IZCAS), China, Tibet Autonomous Region, Nyingchi, Bomê County, around Zhamo Town, 29°50.8590'N, 95°45.8610'E, elevation ca 2800 m, 17.VII.2013, Y. Lin leg.

Etymology.

The species name is a noun in apposition derived from the Chinese pinyin “xiǎodài” (small pouch) and refers to the distinct, pouch-like structure of the external genitalia (Fig. 29B View Figure 29 ).

Diagnosis.

Females of L. duandai sp. nov. can be distinguished from other congeners by the unique, pouch-like external genitalia (Fig. 29B View Figure 29 ) and a pair of fusiform spermathecae with two pairs of apophyses extending both anteriorly and posteriorly (Fig. 29A View Figure 29 ) (vs. an absence of pouch-like external genitalia in congeners).

Female. Total length 2.44; carapace 0.88 long, 0.90 wide; abdomen 1.56 long, 1.25 wide. Carapace round and brown, with three longitudinal dark brown bands, median band three times wider than lateral bands (Fig. 29C View Figure 29 ). Chelicerae brown (Fig. 55A View Figure 55 ). Clypeus light brown. Endites, labium, and sternum dark brown. Abdomen elongated, dorsum with indistinct dark brown spots (Fig. 29C View Figure 29 ), antero-ventrally with a pair of rounded dark brown patches laterally, followed by cone-shaped external genitalia resembling a small pouch, posterior dark brown (Fig. 29D View Figure 29 ). Legs uniformly brown; measurements: I 7.09 (2.03, 0.31, 2.19, 1.56, 1.00), II missing, III 4.53 (1.25, 0.31, 1.25, 1.09, 0.63), IV 6.64 (1.80, 0.31, 2.03, 1.56, 0.94). Epigastric area (Fig. 29B View Figure 29 ): inverted triangular pouch. Endogyne (Fig. 29A View Figure 29 ): pair of connected, fusiform spermathecae with anterior and posterior extensions.
