Diagnosis. Male distinguished by configuration of palp, notably shape of tegular apophysis with two close acute protrusions ( Fig. 10 View FIGURES 8 – 11 ; cf. D. atropalpis : Fig. 8 View FIGURES 8 – 11 ); female by shape of epigyne, notably long median septum almost covering opening of median cavity ( Fig. 11 View FIGURES 8 – 11 ; cf. D. atropalpis : Fig. 9 View FIGURES 8 – 11 ).

Description. Male (from Ootacamund, India). Total length 4.4, carapace 2.55 long, 1.90 wide.

Prosoma ( Fig. 3 View FIGURES 1 – 7 ). Dorsum brown with yellow median and lateral bands, marginal bands brownish grey, more or less broken into blotches. Margin black. Clypeus yellowish, with white pubescence. Chelicerae yellowish with greyish brown longitudinal stripes. Sternum yellowish, slightly greyish brown.

Eyes. Width of row I 42, row II 61, row III 77, row II–III 60. Diameter of AME 10, ALE 8, PME 24, PLE 18. Distance between AME 6, between AME and ALE 2.

Opisthosoma ( Fig. 3 View FIGURES 1 – 7 ). Dorsum with yellowish-grey lanceolate stripe bordered with few dark dots. Median light yellowish band behind lanceolate stripe with row of pairwise arranged dark dots, situated at each side of midline, continuing backwards. Dorsum on each side of light median band more or less speckled with black. Sides and venter yellowish, sides with few dark dots.

Legs ( Table 1 View TABLE 1 ). Light brownish-yellow without annulation. TiI with two retrolateral spines.

Palp ( Fig. 10 View FIGURES 8 – 11 , 44–49 View FIGURES 44 – 49 ). Pt 0.50, Ti 0.50, Cy 1.15. Most of Fe, entire Ti and most of Cy greyish-brown. Apical part of Fe, most of Pt and Cy apically yellowish. All segments with dark hairs; yellowish parts of Fe and Pt in addition with whitish hairs (most of which missing in males examined; cf. Gravely's statement cited in Remarks below). Bulbus at level of embolus comparatively wide. Tegular apophysis with two acute projections in basal half ( Figs 48, 49 View FIGURES 44 – 49 , cf. D. atropalpis : Fig. 13 View FIGURES 12 – 18 ). Posterior subpaleal process large ( Figs 45– 47 View FIGURES 44 – 49 ), only anterior portion (portion above dotted line in Fig. 46 View FIGURES 44 – 49 ) sclerotised, posterior portion membraneous, with pointed process partly surrounding paleal apophysis ( Fig. 46 View FIGURES 44 – 49 ). Embolus with laminar extension along inner side terminating in a process distally ( Figs 44, 45 View FIGURES 44 – 49 ).

Female (from Ootacamund, India). Total length 4.80, carapace 2.55 long, 1.90 wide.

Prosoma and opisthosoma ( Fig. 4 View FIGURES 1 – 7 ). Similar to male in colouration. Dorsal light yellowish median band on opisthosoma, with row of black dots in pairs posterior to lanceolate stripe, more distinct than in male because sides laterad to median band more dark.

Legs ( Table 1 View TABLE 1 ). As in male but sometimes with very weak indistinct darker annulation.

Eyes. Width of row I 41, row II 60, row III 76, row II–III 60. Diameter of AME 10, ALE 8, PME 23, PLE 18. Distance between AME 5, between AME and ALE 2.

Epigyne ( Figs. 21, 22 View FIGURES 19 – 22 , 25 View FIGURES 23 – 28 , cleared Fig. 31 View FIGURES 29 – 32 ). Opening of median cavity narrow, most of it covered by a median septum. Each side with lateral elevation extending into a more or less triangle-shaped sclerite covering the receptacle. Bottom of median cavity corrugated, with characteristic shape in dorsal view ( Fig. 22 View FIGURES 19 – 22 ).

Size variation. Carapace length: males 2.20–2.55 (n=4), females 2.15–2.80 (n=15); tibia I vs. carapace length in Fig. 50 View FIGURE 50 .

Remarks. Gravely (1924) neither illustrated nor documented any particular details of the male apart from mentioning (p. 610) that "the male can be distinguished by the purer white pile on the upper surface of the femora of the palps, and by the continuance of this pile on to the inner side of the patella".

Tikander and Malhotra (1980) placed Pardosa lahorensis Dyal, 1935 (from Pakistan) as a synonym to P. oakleyi but this was not considered in Mathew et al. (2009) or listed in Platnick (2010). I support this synonymy from studying material identified as Pardosa lahorensis collected in NW India (Ludhiana), only about 150 km from Lahore. Pardosa oakleyi has repeatedly (e. g., Mushtaq et al. 2003) been reported as a common species in fields of various crops in Pakistan.

Sadana (1971) illustrated an inflated bulbus, which he ascribed to P. lahorensis . Although this illustration is somewhat crude, it depicts a tegular apophysis (named 'conductor'), which is characteristic in shape as for P. oakleyi , as well as a subpaleal sclerite (named 'terminal apophysis').

Distribution. Pakistan, India, Bangladesh. A record from Vietnam (Pham Din et al. 2007) could not be verified as part of this study.
