Types.

Holotype: ♀ (IZCAS), China, Tibet Autonomous Region, Xigaze, Gyirong County, Zalong Village, 28°22.8650'N, 85°21.1580'E, elevation ca 2715 m, 31.VIII.2014, Y. Li leg.

Etymology.

The species name is a noun in apposition derived from the Chinese pinyin “sānjiǎo” (triangle) and refers to the distinct triangular shape of the external genitalia.

Diagnosis.

Females of L. sanjiao sp. nov. can be distinguished from other congeners by the distinct triangular form of the external genitalia (Fig. 35B View Figure 35 ) (vs. the absence of triangular external genitalia in congeners), and a pair of transverse linear spermathecae (Fig. 35A View Figure 35 ) (vs. the absence of linear spermathecae in congeners).

Description.

Female. Total length 3.80; carapace 1.20 long, 1.20 wide; abdomen 2.60 long, 1.60 wide. Carapace round and brown, with three longitudinal dark brown bands, median band four times wider than the lateral band (Fig. 35C View Figure 35 ). Chelicerae brown (Fig. 55C View Figure 55 ). Clypeus brown, with dark brown band medially. Endites dark brown, light brown basally. Labium and sternum dark brown. Abdomen elongated, dorsum with scattered dark brown spots laterally, with dark brown median stripes (Fig. 35C View Figure 35 ), antero-ventrally light brown with a distinct triangular external genitalia region, with indistinct dark brown patches posteriorly (Fig. 35D View Figure 35 ). Legs uniformly brown; measurements: I 17.49 (4.81, 0.50, 5.13, 5.13, 1.92), II 12.90 (3.80, 0.50, 3.60, 3.60, 1.40), III 9.17 (2.88, 0.40, 2.40, 2.40, 1.09), IV 13.67 (4.17, 0.50, 3.75, 3.75, 1.50). Epigastric area (Fig. 35B View Figure 35 ): triangular pale brown patch with posterior yellowish slit. Endogyne (Fig. 35A View Figure 35 ): a pair of transverse, linear spermathecae, with the posterior pair curving downwards, slightly longer than the anterior pair; both anterior and posterior pairs with rounded tips and similar in width.
