Diagnosis. Males can be easily recognized by the distally expanded, blunt-tip of the palpal bulb ( Figs. 3 View FIGURE 3 A, B; figs. 830–837 Platnick et al. (2011). Females can be recognized by the dark undulated transverse ridge, near the epigastric furrow ( Figs. 3 View FIGURE 3 C, D).

Description. Description based on the four specimens listed above. Also see Platnick et al. (2011) for a detailed description.

MALE: Body length 1.30. Pars cephalica slightly elevated, pars thoracica sloping gradually to rounded posterior margin. Median portion of sternum with ordinary setae and without distinct pits. Scuto-pedicel region with straight ridge. Genitalia: distal portion of palpal bulb relatively large, as high as cymbium. Bulb distally expanded with a blunt tip, base without triangular projection ( Figs. 3 View FIGURE 3 A, B).

FEMALE: Body length 1.54. Somatic morphology as male ( Fig. 2 View FIGURE 2 A, 2B, 2D, 2F). Genitalia: postepigastric region with dark undulated transverse ridge positioned near the epigastric furrow. Postepigastric region with posterior genitalic tube and without any triangular projections, posterior tube very short and narrow ( Figs. 3 View FIGURE 3 C, D).

Intraspecific variation. Color of carapace and dorsal scuta diverge from pale orange to orange. Scuto-pedicel region with medially straight weak sclerotized ridge ( Fig. 2 View FIGURE 2 F).

Distribution. Sri Lanka. Previous record: Galle. New records: Matale District, NIFS Arboretum (L 17), Knuckles (L 44).
