Leclercera yuanzhui sp. nov. Figs 38 View Figure 38 , 56J View Figure 56 , 58 View Figure 58


Holotype: ♀ (IZCAS), China, Yunnan Province, Wenshan State, Jinping County, mountain around bus station (direction of timber factory), 22°47.6920'N, 103°13.3360'E, elevation ca 1399 m, 14.V.2015, Z. Chen and F. Li leg.


The species name is a noun in apposition derived from the Chinese pinyin “yuánzhuī” (conical) and refers to the shape of the external genitalia with a genitalic lobe that greatly resembles the shape of a conical flask (Fig. 38B, C View Figure 38 ).


Females of L. yuanzhui sp. nov. resemble L. maochong sp. nov. and L. shanzi sp. nov. but can be distinguished by the presence of a protruded genitalic lobe (Fig. 38C View Figure 38 ) (vs. the absence of a genitalic lobe), the presence of a pair of widely separated semi-circular bodies posteriorly (vs. the absence of semi-circular bodies or with circular bodies), and entire spermathecae rather thin and narrow (Fig. 38A View Figure 38 ) (vs. entire spermathecae rather thick and wide).


Female. Total length 2.20; carapace 0.70 long, 0.90 wide; abdomen 1.50 long, 0.90 wide. Carapace round and brown, with three dark brown longitudinal bands, median band six times wider than lateral band (Fig. 38D View Figure 38 ). Chelicerae brown (Fig. 56J View Figure 56 ). Clypeus dark brown medially. Endites brown, light brown basally. Labium brown. Sternum with purplish stripes laterally. Abdomen elongated, dorsum with dark brown spots, posteriorly with dark brown stripes (Fig. 38D View Figure 38 ), antero-ventrally with conical shaped external genitalia region, with protruded genitalic lobe (Fig. 38C View Figure 38 ), posterior with complex pattern of dark brown spots. Legs uniformly brown; measurements: I-II missing, III 4.91 (1.41, 0.20, 1.40, 1.20, 0.70), IV 8.08 (2.40, 0.31, 2.40, 2.03, 0.94). Epigastric area (Fig. 38B View Figure 38 ): inverted triangular brown patch sagging with distinct genitalic lobe. Endogyne (Fig. 38A View Figure 38 ): pair of spermathecae resembling inverted “V” with loops, posteriorly with a pair of semi-circular bodies.
