Females of G. wangjiangensis sp. nov. differ from all other Ganthela species by the W-shaped posterior part of the genital area, and can be further distinguished from G. venus sp. nov. by the connected basal genital stalks ( Fig. 7A, B ). Ganthela wangjiangensis sp. nov. differs from all other Ganthela species by the following unique nucleotide substitutions in the standard DNA barcode alignment: G (54), C (101), C (179), C (320), A (336), T (372), C (386), C (422), G (476), T (512), and C (632).

Description

Female (holotype). Carapace and opisthosoma light brown; tergites slightly dark brown; sternum narrow, length more or less twice of width; a few long pointed hairs running over ocular mound in a longitudinal row; chelicerae robust, with promargin of cheliceral groove with 12 strong denticles of variable size; legs with strong hairs and spines; opisthosoma with 12 tergites, with tergites 2–6 larger than others, and the with tergite 4 being largest; seven spinnerets. Measurements: BL 11.50 , CL 4.90 , CW 4.30 , OL 6.40 , OW 5.55 ; ALE > PLE > PME > AME; palp 7.94 (2.78 + 1.50 + 1.48 + 2.18), leg I 9.10 (3.05 + 1.35 + 1.70 + 1.80 + 1.20), leg II 9.50 (2.80 + 1.67 + 1.71 + 2.02 + 1.30), leg III 10.00 (2.75 + 1.76 + 1.57 + 2.45 + 1.47), and leg IV 13.62 (3.83 + 1.92 + 2.28 + 3.52 + 2.07) .

Female genitalia

The posterior part of genital area W-shaped ( Fig. 7A, B ), with a pair of receptacular clusters separated from each other, and with the basal parts of short genital stalks fused ( Fig. 7A, B ).

Distribution

Fujian (Putian) Province, China.

Remarks

Ganthela wangjiangensis sp. nov. was collected within 1 km of G. venus sp. nov., but at a higher altitude.
