Etymology.

The species name is a noun in apposition derived from the holotype locality.

Diagnosis.

Simaetha huigang sp. nov. closely resembles S. cheni from China in the general shape of the habitus and copulatory organs, but it differs in the following: 1) dorsal tibial apophysis less than 1/4 tibial length in retrolateral view (Fig. 16B ) versus more than 1/2 tibial length in S. cheni ( Wang and Li 2021: fig. 18C); 2) cheliceral paturon lacks process (Fig. 17F, G ) versus process present mediolaterally on anterior surface in S. cheni ( Wang and Li 2021: fig. 19G, H); 3) epigynal hood almost as long as posterior chamber of spermathecae (Fig. 17A, B ) versus less than 1/2 length of posterior chamber of spermathecae in S. cheni ( Wang and Li 2021: fig. 19A-C).

Description.

Male (Figs 16 , 17C, D, F, G ). Total length 2.77. Carapace 1.36 long, 1.11 wide. Abdomen 1.60 long, 1.17 wide. Clypeus 0.02 high. Eye sizes and inter-distances: AME 0.32, ALE 0.17, PLE 0.15, AERW 0.92, PERW 1.04, EFL 0.75. Legs: I 2.96 (1.00, 1.20, 0.43, 0.33), II 2.11 (0.68, 0.73, 0.40, 0.30), III 1.93 (0.65, 0.60, 0.40, 0.28), IV 2.41 (0.85, 0.83, 0.43, 0.30). Carapace red-brown to dark, squarish, slightly narrowed at anterior half, covered with dense setae and scales. Fovea indistinct. Chelicerae yellow-brown, with two promarginal and one retromarginal fissidental tooth with two cusps. Endites longer than wide, bearing dense setae at ental margins. Labium darker than endites. Sternum 1.5 times longer than wide, covered by pale, long, thin setae. Legs I strongest, covered with pale and blue scales on enlarged femora and tibiae, with two pairs of spines on tibiae and metatarsi, respectively; other legs yellow to dark. Abdomen oval, the dorsum with a large, irregular dark band followed by a broad, transverse, yellow band, entirely covered by large scutum, bearing short, pale, thin setae; venter dark brown, laterally with pair of longitudinal, pale setal stripes.

Palp (Fig. 16A-D ): tibia wider than long in ventral view, with short, straight, lamellar dorsal apophysis slightly pointed apically; cymbium about 1.8 times longer than wide, with lamellar, proximal retrolateral process; bulb almost round, with sperm duct extending along submargin; embolus flat, about 1/2 the bulb length, originating from antero-prolateral portion of bulb, slightly curved medially, blunt apically.

Female (Fig. 17A, B, E ). Total length 2.99. Carapace 1.32 long, 1.02 wide. Abdomen 1.70 long, 1.09 wide. Clypeus 0.02 high. Eye sizes and inter-distances: AME 0.30, ALE 0.16, PLE 0.15, AERW 0.91, PERW 1.02, EFL 0.67. Legs: I 2.19 (0.73, 0.73, 0.43, 0.30), II 1.70 (0.55, 0.60, 0.30, 0.25), III 1.64 (0.53, 0.53, 0.33, 0.25), IV 2.23 (0.78, 0.80, 0.40, 0.25). Habitus similar to that of male except paler.

Epigyne (Fig. 17A, B ): wider than long, with large, central, bell-shaped hood almost equal in length to posterior chamber of spermathecae; copulatory openings lateral to base of hood, slit-like; copulatory ducts thick, connected with anterior portions of anterior chambers of spermathecae; spermathecae divided into two chambers, anterior chamber oval, extending posteriorly, posterior chamber almost spherical, separated from each other by 1/4 their diameter; fertilization ducts originating from anterior portions of posterior chamber of spermathecae, extending anterolaterally.

Distribution.

Known only from the type locality in Yunnan, China.
