Legs with annuli. Length of legs: I 4.57 (1.23, 0.34, 1.19, 1.08, 0.73), II 4.06 (1.12, 0.32, 0.94, 1.02, 0.66), III 3.19 (0.91, 0.25, 0.71, 0.74, 0.58), IV 4.12 (1.13, 1.23, 1.03, 0.61). Tibial spine formula: 2-2 - 2 - 2. TmI 0.58 and TmIV present. Opisthosoma 1.69 long, 1.13 wide, all other characters same as in male, except darker in color (Fig. 1 C, D). Epigyne (Fig. 3 A – D). Protruding, ventral plate posteriorly longer than wide, distal end drop-shaped with distinct depression, lateral pockets (LP) indistinct, entrance groove (EG) present laterally (Fig. 3 C, D); posterior median plate (PMP) small, somewhat rectangular (Fig. 3 D). Spermathecae (S) 9 - shaped, present antero-laterally (Fig. 3 D). Diagnosis Drapetisca dentata sp. nov. resembles D. socialis (Sundevall, 1833) in having the similar paracymbium in male palp and epigyne with similar morphology (Fig. 2 A – D; Locket and Millidge 1953, fig. 222 A – B, E, H), but can be distinguished by the lamella characteristica hook-shaped, distal end with a tooth in retrolateral view in D. dentata sp. nov. (Fig. 2; vs. strongly curved, tip with 4 branches in D. socialis); proximal cymbial apophysis absent in both D. dentata sp. nov. (Fig. 2 C; vs. present in D. socialis). The female can be distinguished by the posterior part of the ventral plate drop-shaped, with a depression at the apex in ventral view in D. dentata sp. nov. (Fig. 3 A – D; vs. somewhat rectangular in D. socialis). Etymology The specific epithet is derived from the Latin adjective “ dentatus,” meaning “toothed,” and referring to the distal part of the lamella characteristica apically with a tooth. Distribution Known only from the type locality (Fig. 4).
