Etymology.
Formed from the Chinese words for two ( èr 二) and circle ( huán 环), referring to the paired loops of copulatory ducts ( Fig. 4E View Figure 4 ); noun.
Diagnosis.
This new species can be distinguished from other congeners by the 2 coils of the unilateral copulatory ducts around the spermathecae ( Fig. 4 E–F View Figure 4 ).By having a posterior tubercle on the abdomen ( Fig. 4 A–C View Figure 4 ) it differs from C. huifengi sp. nov. ( Fig. 2 A–D View Figure 2 ), C. anaktakun and C. discobulbus ( Labarque and Griswold 2014: figs 5 A–C, 6 A–C, 7 A–C).
Description.
Female (holotype): Carapace pear-shaped, black. Sternum tan. Legs dark brown. Abdomen obovate with posterior tubercle, dark black, ventrally darker than dorsally, covers sparse setae ( Fig. 4 A–C View Figure 4 ). Measurements: Total length 1.66. Carapace 0.62 long, 0.60 wide. Clypeus 0.14 high. Sternum 0.37 long, 0.38 wide. Abdomen 1.21 long, 1.04 wide. Length of legs: I 2.03 (0.65, 0.25, 0.43, 0.39, 0.31); II 1.80 (0.55, 0.23, 0.38, 0.34, 0.30); III 1.39 (0.42, 0.18, 0.26, 0.28, 0.25); IV 1.78 (0.55, 0.23, 0.40, 0.34, 0.26).
Epigyne ( Fig. 4 D–F View Figure 4 ): plate weakly sclerotized, nearly rectangular, with an indistinct central pit and pair of posterolateral pockets. Spermathecae barely visible through the integument; lateral wings well developed, with sclerotized glandular ducts in the dorso-medial; spermathecae globose, closely spaced and almost adjacent; copulatory ducts form a half loop in the ventral later wings, followed by 2 complete loops surround the spermathecae, and finally connect to the spermathecae ( Fig. 4E View Figure 4 ); fertilization ducts short and twisty, arise from the dorsal side of spermathecae ( Fig. 4F View Figure 4 ).
Male. unknown.
