Type material.

Holotype ♀ (IZCAS-Ar42954), China: Yunnan: Xishuangbanna, Mengla County, Menglun Township, 55 kilometers from Xishuangbanna National Nature Reserve, ravine rainforest (21°57.68'N, 101°12.03'E, 718 ± 11 m alt.), 12.xi.2013, Q. Zhao and Z. Chen leg. Paratype 1♀ (IZCAS-Ar42955), same data as holotype.

Etymology.

The specific name is a patronym in honor of Zhigang Chen, one of the collectors of the new species; noun (name) in genitive case.

Diagnosis.

Synagelides cheni sp. nov. resembles that of S. tangi Liu, Chen, Xu & Peng, 2017 from China in having anteriorly located, paired, arched atrial ridges and a centrally located epigynal hood, but it can be easily distinguished by the following: 1) atrial ridges occupying nearly entire anterior 1/2 of epigyne (Fig. 18 A, B ) versus occupying about anterior 1/3 of the epigyne in S. tangi ( Liu et al. 2017: figs 4C, D, 5E, F); 2) epigynal hood about three times wider than long (Fig. 18A ) versus about as long as wide in S. tangi ( Liu et al. 2017: figs 4C, 5E).

Description.

Female (Fig. 18 ). Total length 4.38. Carapace 2.04 long, 1.46 wide. Abdomen 2.33 long, 1.28 wide. Clypeus 0.05 high. Eye sizes and inter-distances: AME 0.50, ALE 0.31, PLE 0.29, AERW 1.48, PERW 1.45, EFL 1.14. Legs: I 3.74 (1.58, 1.28, 0.55, 0.33), II 3.56 (1.10, 1.33, 0.75, 0.38), III 3.71 (1.10, 1.30, 0.93, 0.38), IV 5.13 (1.45, 1.98, 1.25, 0.45). Carapace stippled, yellow to dark, covered with dark and pale setae. Fovea oval, hollow. Chelicerae yellow, with two promarginal teeth and one retromarginal fissidental tooth with two cusps. Endites slightly paler than chelicerae. Labium dark yellow, bearing several dark setae at distally. Sternum yellow, almost shield-like. Legs pale to yellow, with four and two pairs of ventral spines on metatarsi and tibiae I, respectively. Abdomen elongated, dorsum dark brown, with two pairs of muscle depressions medially, two wavy, transverse dark stripes and two transverse dotted lines posteriorly; venter pale, with longitudinal, gray-brown stripe anteromedially.

Epigyne (Fig. 18A, B ): slightly longer than wide, with pair of arched atrial ridges occupying nearly entire anterior half, subtrapezoid median plate bearing an inverted boat-shaped hood about three times wider than long; copulatory openings small, situated at base of atrial ridges; copulatory ducts descending, forming C-shape, terminally with transversely extending, bar-shaped accessory glands; spermathecae almost L-shaped, with spherical lateral and oval ental portions; fertilization ducts lamellar, originating from anterior margins of ental portions of spermathecae, extending transversely.

Male. Unknown.

Distribution.

Known only from the type locality in Yunnan, China.
