DIAGNOSIS. Total length 27–46 mm. Male with longer metasomal segments and telson than female. Segments of pedipalps approximately the same length and width in both sexes. Ratio of pedipalp chela length/ width 3.41– 3.79 in male. Pedipalp movable finger clearly longer than chela manus in both sexes, but in largest male specimens could be shorter than manus. Base coloration reddish. Pedipalps and legs with brown maculation, identical on femur and patella. First metasomal segment bears 10 carinae, second through fourth segments bear eight carinae, fifth segment bears five carinae in female and three to five in male. Terminal tubercle of each dorsal carina on metasomal segments of both sexes scarcely larger than preceding tubercles. Subaculear tooth wide and rounded, dorsally with granules in three or four rows; four or six symmetrical granules and one or two granules on tip. Glabrous zone along posterior margin of fifth sternite absent. Pectinal teeth number 13–18 in both sexes. HEMISPERMATOPHORE (Figs. 283–286). Trunk moderately narrow, elongate, more than twice as long as capsule region. Flagellum long, slender, laminiform, with broad hyaline fin along internal margin of cylindrical core, distally coiled. Median lobe narrow, distally truncate, with thin dorsal lamina near internal margin. Basal lobe greatly enlarged, a narrow, angular, pointed hook-like process arising dorsally, separated from base of median lobe. VARIABILITY. There is high variability in morphometric characters between small males 27–32 mm long after the fourth ecdysis, and males 40–46 mm long after the fifth ecdysis. DISTRIBUTION. Sri Lanka.
