Castianeira furva View in CoL sp. nov.
( Figs 1A–J View FIGURE 1 A – J , 2A–J View FIGURE 2 A – J , 3A–F View FIGURE 3 A – F , 4A–C View FIGURE 4 A – C )
Etymology. The specific epithet is an adjective and refers to the body colour of the black morph of the new species. Latin furvus = black.
Diagnosis. Both males and females of C. furva sp. nov. can be separated from C. tinae Patel & Patel, 1973 and C. zetes Simon, 1897 by the following combination of characters: dorsal opisthosoma of C. furva sp. nov. with longitudinal bands, but in both C. tinae and C. zetes dorsal opisthosoma possesses transverse bands; embolus of C. furva sp. nov. is short, while C. tinae and C. zetes with comparatively longer emboli; C. furva sp. nov. with nearly medially placed copulatory openings, while in C. tinae and C. zetes , copulatory openings lying close to the posterior border of the epigynum (compare Figs 1A–C View FIGURE 1 A – J , 2A–F View FIGURE 2 A – J , 3A–E View FIGURE 3 A – F with Patel & Patel 1973: figs 3a, 3d–f and Majumder & Tikader 1991: figs 264–266, 269, 292–294).
