Type material.

Holotype: ♀ (IZCAS-Ar41674), China: Yunnan: Xishuangbanna, Jinghong City, Guanping Town, Shiwudui, 22.2310°N, 100.9172°E, 872 m elev., 27.IV.2018, Zhengzhong Huang leg. Paratype ♀ (IZCAS-Ar41675), same data as holotype.

Etymology.

The species is named after Mr Zhengzhong Huang, who collected the holotype and paratype; noun (name) in genitive case.

Diagnosis.

Females of Phrynarachne zhengzhongi sp. nov. are similiar to P. brevis by the shape of the spermathecae; the posterior edge of the spermathecae is as wide as the anterior edge. However, females of P. zhengzhongi sp. nov. can be distinguished by the triangular tubercles on the abdomen (vs long, slender apophysis in P. brevis ), the epigyne with a hood, and the absence of sclerotized margins (vs hood absent, sclerotized margins present in P. brevis ), and the straight anterior edge of the median plate (vs recurved in P. brevis ).

Description.

Female (Figs 16 , 20 ): total length 10.79, carapace 5.27 long, 5.53 wide, brown, with small projection, ocular tubercle white. Projection present between ALE and PLE. Eye sizes and interdistances: ALE 0.21, AME 0.17, PLE 0.18, PME 0.10; ALE-AME 0.35, AME-AME 0.66, PLE-PME 0.50, PME-PME 0.87. Chelicerae pale yellow, with two promarginal teeth and one retromarginal tooth; gnathocoxae, labium yellow, labium 1.19 long, 0.94 wide. Sternum yellow. Legs brown, femora I and II with dense, varying-sized tubercles; tibiae and metatarsi I, II with dense asymmetrical ventral spines (I, tibia 22, metatarsus 43; II, tibia 17, metatarsus 37). Leg measurements: I 14.43 (4.71, 5.91, 2.35, 1.46), II 14.78 (5.05, 6.31, 2.09, 1.33), III 7.76 (2.24, 3.48, 1.03, 1.01), IV 7.30 (2.44, 3.01, 0.92, 0.93). Leg formula: 2134. Opisthosoma dorsally light yellow, each side with 22 tubercles, each with some tubercles.

Epigyne (Fig. 16 ). Sclerotized margins inconspicuous; median plate obvious, with a posterior hood, anterior and posterior edges almost straight, the ratio of width to length is 4:1; copulatory opening inconspicuous; spermathecae kidney-shaped, the ratio of posterior edge to anterior edge length is 1:1. Fertilization duct transverse.

Distribution.

Known only from the type locality.
