Type material.

Holotype ♂ (IZCAS-Ar40601), China: Yunnan: Xishuangbanna, Mengla County, Menglun Town, Menglun Nature Reserve, Xishuangbanna Tropical Botanical Garden, Leprosy Village (21°53.59'N, 101°17.30'E, ca 550 m), 29.04.2019, Y. Tong et al. leg. Paratypes 1♀ (IZCAS-Ar40602), same data as holotype; 1♀ (IZCAS-Ar40603), Flower Garden (21°55.80'N, 101°45.41'E, ca 530 m), 1.08.2018, C. Wang et al. leg.

Etymology.

The species name is a patronym in honor of the late Professor Changmin Yin, one of the pioneers of spider taxonomy of China; noun (name) in genitive case.

Diagnosis.

The male of Charippus yinae sp. nov. resembles C. errans Thorell, 1895 by the habitus, shape of the palp, and the cheliceral dentition, but can be easily distinguished by the embolus originating at 9:00 o’clock rather than approximately 11:30 o’clock as in C. errans ( Wanless 1988: fig. 40F), and the RTA is curved towards the bulb medially in retrolateral view, instead of curved towards the bulb terminally as in C. errans ( Wanless 1988: fig. 40H). The female resembles Cytaea alburna Keyserling, 1882 by the very long, coiled copulatory ducts and the small spermathecae but can be easily distinguished by the following: 1) the carapace is slightly narrowed anteriorly rather than almost square as in C. alburna ( Davies and Żabka 1989: 226); 2) the median septum is absent vs present in C. alburna ( Davies and Żabka 1989: 226); 3) the chelicerae have only two promarginal teeth vs three promarginal teeth as in C. alburna ( Davies and Żabka 1989: 226).

Description.

Male (Figs 1 , 2C, D, F, G ). Total length 3.91. Carapace 1.98 long, 1.56 wide. Abdomen 2.04 long, 1.48 wide. Clypeus 0.10 high. Eye sizes and inter-distances: AME 0.38, ALE 0.22, PLE 0.20, AERW 1.28, PERW 1.24, EFL 0.97. Legs: I 3.83 (1.15, 1.61, 0.68, 0.39), II 3.53 (1.07, 1.39, 0.68, 0.39), III 3.78 (1.22, 1.29, 0.88, 0.39), IV 4.27 (1.22, 1.49, 1.07, 0.49). Carapace dark brown, with an irregular red area in the middle of the thoracic part, bearing dense white setae on the cheeks and white and golden setae dorsally. Clypeus dark, with sparse white setae. Fovea longitudinal, dark. Chelicerae red to dark brown, with two promarginal teeth and one retromarginal fissident with two cusps. Endites red-brown, paler inner margin. Labium dark brown. Sternum somewhat shield-shaped, with sparse setae. Legs I red to dark brown; other legs yellow, with dark markings. Abdomen suboval, dorsum hirsute, with two pairs of faint pale patches anteriorly and a pair of posterolateral falcate bands followed by several chevrons; venter dark anteriorly, covered by small spots and thin brown setae.

Palp (Fig. 1A-D ): tibia wider than long in ventral view, with a RTA approximately two times the tibial length, slightly curved medially and blunt at the tip in retrolateral view; cymbium hirsute, proximodorsally with a small process (Fig. 1D , CP) near the RTA base; bulb swollen, with sperm duct strongly curved retrolaterally; embolus originating at around 9:00 o’clock, coiled 1.5 times.

Female (Fig. 2A, B, E ). Total length 3.83. Carapace 1.83 long, 1.38 wide. Abdomen 2.13 long, 1.45 wide. Clypeus 0.10 high. Eye sizes and inter-distances: AME 0.36, ALE 0.23, PLE 0.21, AERW 1.20, PERW 1.14, EFL 0.88. Legs: I 3.08 (0.98, 1.27, 0.49, 0.34), II 2.88 (0.95, 1.10, 0.49, 0.34), III 3.32 (1.10, 1.15, 0.73, 0.34), IV 3.58 (1.12, 1.29, 0.83, 0.34). Habitus similar to that of male except slightly paler.

Epigyne (Fig. 2A, B ): wider than long, with a pair of arc-shaped anterior atrial margins and a pair of lateral atrial margins; copulatory openings small, slit-shaped, located anterolaterally; copulatory ducts very long, curved into a U-shape at the origin, with anterior tubercles and complex coils; spermathecae suboval, separated from each other by almost two times their width; fertilization ducts nearly cordiform.

Distribution.

Known only from the type locality in Yunnan, China.
