Pardosa subhadrae Patel & Reddy, 1993: 128 , fig. 5a–g (♂♀).

Draposa subhadrae: Kronestedt 2010: 49 , figs 7, 27, 32, 42–43, 53 (♀).

Material examined. 2♂, 2♀ ( ZMMU), SRI LANKA, Southern Province, Hambantota District, 6°8'N 81°8'E, 9– 10.01.2012 (M.M. Omelko).

Diagnosis. Male of this species differs from D. atropalpis ( Gravely, 1924) , a species with similarly modified embolus, by having three-branched subpaleal sclerite (two-branched in D. atropalpis ), lack of subapical protrusion of the tegular apophysis, known in all other Draposa species, and the lamella of the tegular apophysis with numerous fine teeth. According to Kronested (2010), the female of D. subhadrae is most similar to D. lyrivulva ( Bösenberg & Strand, 1906) . These two species can be distinguished by the longer scape in D. subhadrae , which is half the length of epigynal atrium, and less than 1/2 of the atrium in similar species.

Description. Male. Total length 5.25, carapace 2.58 long, 2.10 wide. Carapace light yellow with two lateral darkbrown, wavy bands and a median band and poorly distinct broken sublateral stripes formed by dark setae ( Fig. 1 ). Yellow parts of carapace covered with short black and white hairs. Ocular area and eyes black. Chelicerae yellow with darkbrown longitudinal bands ( Fig. 3 ). Endites and labium yellow. Sternum yellow in one male and black in another. Femur and tibia of male palp with black basal parts; patella yellow. Leg segments except tarsus with blackish spots and half rings. Spination of leg I: femur 3d, 2p, 3r; patella 1p, 1r; tibia 3d, 2p, 2r, 2- 2v; metatarsus 2p, 2r, 2- 2v. Leg measurements in Table 1 .

Palp as in Figs 4–10 and 14–18 . Basal 2/3 of cymbium black, terminal 1/3 yellowish. Tegular apophysis (Ta) with wide lamella (Tl) armed with numerous fine teeth (Te), subapical protrusion of the tegular apophysis absent; subpaleal sclerite with three processes (branches), the apical one (Ap), the middle process (Pp) and conductor-like (Co). Embolus modified, widened in distal part before tapering to apex ( Figs 15, 17–18 ).

Female. Described by Kronestedt (2010). Habitus as in Fig. 2 , pattern similar to male but with more distinct sublateral dark stripes. Epigyne as in Figs 11–13 ; scape thin, about 3 times longer than wide, its length about 2/3 the atrial height; atrium rhomboidal, widest at the middle.

Distribution. The species is known from Southeast India and Sri Lanka ( Kronestedt 2010).
