Diagnosis.
This species resembles C. nasalis sp. nov. but can be distinguished by the copulatory ducts twisting 4 × but only 2 × in the latter (Fig. 4D-G View Figure 4 ).
Description.
Female (IZCAS-Ar 40996). Total length 0.80. Carapace 0.36 long, 0.32 wide, 0.32 high. Clypeus 0.12 high. Sternum 0.28 long, 0.20 wide. Abdomen 0.56 long, 0.60 wide, 0.56 high. Length of legs: I 1.16 (0.40, 0.14, 0.26, 0.18, 0.18); II 1.00 (0.32, 0.10, 0.24, 0.14, 0.20); III 0.68 (0.20, 0.10, 0.12, 0.12, 0.14); IV 0.98 (0.34, 0.12, 0.20, 0.14, 0.18).
Somatic characters (Fig. 4A-C View Figure 4 ). Coloration: carapace light brown, centrally smooth, marginally darkish, without modified pattern. Chelicerae, endites, labium, and sternum light brown. Abdomen charcoal gray, with irregular light patches. Prosoma: carapace nearly pear shaped, with two strong setae medially. Cephalic region elevated. PER straight. Chelicerae covered with setae anteriorly. Sternum smooth, slightly plump, truncated posteriorly, fused to labium. Legs: light brown, each segment with distal black ring, covered with setae and bristles. Abdomen: anteriorly rounded, posteriorly quadrate, bears sparse, long setae, with a pair of posterolateral abdominal tubercles. Spinnerets light brown.
Epigyne (Fig. 4D-G View Figure 4 ): epigynal area lightly sclerotized, with some setae. Internal structures faintly visible via translucent tegument. Scape small, unobvious. Paired spermathecae separated by ~ ½ their diameter. Fertilization ducts originating inside middle margin of spermathecae, bent downward, reverse course under the spermathecae. Copulatory opening small, located at end of scape. Copulatory ducts long, connected to posteriorly ventral surface of spermathecae, twisted 4 × under spermathecae. Bilateral copulatory ducts merged into a Y-shaped atrium before copulatory opening.
Male. Unknown.
Taxonomic justification.
Although we were unable to obtain molecular data for this species, the configuration of the vulva and the modified habitus leave little doubt that it is a member of the genus Crassignatha and not Patu . Therefore, we propose a new combination, Crassignatha bicorniventris (Lin & Li, 2009) comb. nov., transferring it from Patu .
Distribution.
China (Hainan) (Fig. 38 View Figure 38 ).
