Type material.

Holotype ♀ (NHMSU Ar 013), China: Yunnan Province, Longling County, Zhen’an Township, Bangbie Village, at stream at km 6.8 on Road S317, shady embankments along stream, dusting webs in understory (24.81333°N, 98.83280°E; 1560 m), 22.VIII.2018, Y. Lin et al. leg.; 1♀ (NHMSU-HA137) used for sequencing, GenBank: MT992015, same data as for preceding.

Diagnosis.

Crassignatha bangbie sp. nov. is similar to C. pianma but can be distinguished by the copulatory duct having one inflection point in middle of vulva rather than two inflection points as in the latter (Fig. 3F, G View Figure 3 ).

Description.

Female (holotype). Total length 0.80. Carapace 0.32 long, 0.36 wide, 0.32 high. Clypeus 0.14 high. Sternum 0.20 long, 0.20 wide. Abdomen 0.52 long, 0.56 wide, 0.60 high. Length of legs: I 1.16 (0.40, 0.12, 0.28, 0.16, 0.20); II 0.92 (0.28, 0.12, 0.24, 0.12, 0.16); III 0.84 (0.24, 0.12, 0.16, 0.12, 0.20); IV 0.96 (0.32, 0.08, 0.24, 0.16, 0.16).

Somatic characters (Fig. 3A-C View Figure 3 ). Coloration: carapace, sternum, chelicerae, endites, and labium brown. Abdomen dark orange with some light patches. Prosoma: carapace nearly pear shaped. PER straight. Chelicerae covered with setae anteriorly. Labium nearly semicircular. Sternum smooth, bears sparse setae and small light patches, subcordate, truncated posteriorly. Legs: brown with a little black, covered with setae and bristles. Abdomen: anteriorly round, posteriorly relatively pointed, with light patches. Spinnerets gray, anterior spinnerets larger than posterior spinnerets.

Epigyne (Fig. 3D-G View Figure 3 ): epigynal area slightly sclerotized, with few setae. Scape stubby, protruded. Internal structures faintly visible via translucent tegument. Spermathecae separated by approximately their diameter. Fertilization ducts starting at posterior margin of spermathecae. Copulatory ducts connected to the dorsal-subcentral surface of spermathecae, bent toward the central area of vulva to form an inflection point, then retracing under the spermathecae, fused at the copulatory opening. Copulatory openings large, rounded in ventral view, located at end of scape.

Male. Unknown.

Etymology.

The specific name is derived from the type locality; noun in apposition.

Distribution.

China (Yunnan) (Fig. 38 View Figure 38 ).
