Treatment

Leclercera mianqiu sp. nov. Figs 1 View Figure 1 , 2 View Figure 2 , 56H View Figure 56 , 58 View Figure 58

Types.

Holotype: ♂ (IZCAS), Indonesia, Sulawesi, mountain in Palopo, 2°57.7790'S, 120°8.5230'E, elevation ca 370 m, 13.IX.2017, H. Liu and Z. Chen leg. Paratype: 1♀ (IZCAS), same data as holotype.

Etymology.

The species name is a noun in apposition derived from the Chinese pinyin “miánqiú” (cotton ball) and refers to the unique fluffy ball of bristles on the bulb resembling a cotton ball (Fig. 2B View Figure 2 ).

Diagnosis.

Males of L. mianqiu sp. nov. resemble L. selasihensis sp. nov. but can be distinguished by the presence of an attached fluffy ball of bristles adjacent to the embolus (vs. an absence of bristles but the presence of a conductor adjacent to embolus), presence of a medial-retrolateral apophysis on the cymbium (Fig. 2C View Figure 2 ) (vs. the presence of a postero-retrolateral apophysis on the cymbium (Fig. 37D View Figure 37 )), the presence of two strong prolateral setae on the femur (Fig. 2C View Figure 2 ) (vs. the presence of one strong prolateral seta on the femur (Fig. 37D View Figure 37 )); females can be distinguished by their rather pale coloration (vs. dark coloration), their stalked spermathecae that are globose distally (Fig. 1A View Figure 1 ) (vs. bean-shaped spermathecae that are strongly depressed anteriorly, and with median spiralled ducts (Fig. 36A View Figure 36 )).

Description.

Male (Holotype). Total length 2.60; carapace 1.00 long, 1.00 wide; abdomen 1.60 long, 0.80 wide. Carapace round and pale yellow, margin with black bands laterally (Fig. 1C View Figure 1 ). Chelicerae dark brown (Fig. 56H View Figure 56 ). Clypeus greyish brown. Endites pale yellow with dark edges. Labium light brown. Sternum pale yellow, with dark brown spots centrally. Abdomen elongated, dorsum with complex dark brown sports, antero-ventrally with rectangular brown patch, posterior half pale yellow with dark and light brown spots. Legs uniformly brown; measurements: I 31.16 (7.69, 0.40, 8.01, 12.82, 2.24), II 19.21 (5.45, 0.40, 5.13, 6.73, 1.50), III 14.90 (4.25, 0.40, 4.25, 4.75, 1.25), IV 20.97 (6.41, 0.40, 6.09, 6.47, 1.60). Palp (Fig. 2A-D View Figure 2 ): femur slender, four times longer than patella, anteriorly with two strong setae prolaterally, dark purplish proximally and distally; patella not swollen, dark purplish; tibia 1.5 times shorter than femur, dark purplish proximally and distally; cymbium two times shorter than femur, dark purplish distally, with broad and slightly curved medio-retrolateral apophysis; bulb light brown, obovoid, with embolus and a clump of bristles distally; embolus slightly curved, as long as tegulum, adjacent to bristles; bristles forming a rounded fluffy clump anteriorly, adjacent to embolus (Fig. 2B View Figure 2 ).

Female (Paratype). General features and coloration similar to those of male (Fig. 1D, E View Figure 1 ). Measurements: total length 2.76; carapace 0.88 long, 0.86 wide; abdomen 1.88 long, 1.00 wide. Leg measurements: I 20.59 (5.13, 0.40, 5.45, 7.69, 1.92), II 12.25 (3.25, 0.40, 3.40, 4.00, 1.20), III missing, IV 14.49 (4.00, 0.40, 4.00, 4.81, 1.28). Epigastric area (Fig. 1B View Figure 1 ): an elliptical patch with distinct dark brown lines anteriorly and posteriorly, posterior pale yellow. Endogyne (Fig. 1A View Figure 1 ): stalked spermathecae, globose distally and with a pair of deltoid-shaped receptacles, spermathecal heads almost five times wider than the stalks, stalks three times longer than heads.
