TYPES: Male holotype and female allotype from the Sinharaja Forest Reserve, Ratnapura, Sri Lanka (Aug. 23, 1981), deposited in NML (PBI_OON 31759).

ETYMOLOGY: The specific name is a noun in apposition taken from the type locality.

DIAGNOSIS: Males resemble those of B. bowleri in having the sternum medially depressed, but have the depression largely confined to the posterior half of the sternum (figs. 243, 244); they are easily recognized by the unusually long endite tip and the presence of a second, long process on the lateral edge of the endite (figs. 243, 244, 255, 256). Females have a distinctive, broadly triangular process that fills most of the space between the epigastric furrow and the posterior spiracular groove (figs. 267, 268).

MALE (PBI_OON 31759, figs. 240–258): Total length 1.49. Carapace brown, without any pattern; pars cephalica strongly elevated in lateral view; posterolateral edge with pair of pits, posterior declivity steep, top margin with three enlarged setae with enlarged bases on each side, posterior margin squared, with pair of dark triangular sclerotizations. Sternum without pits, with median concavity occupying most of sternal length, posterior ridge produced, bearing three large tubercles on each side. Scuto-pedicel region with deeply W-shaped scutal ridge, extremely weak medially but with one enlarged tubercle opposite each pedicel triangle. Palpal bulb with dorsally directed, flattened tip, tip shorter than in B. bowleri .

FEMALE (PBI_OON 31759, figs. 259– 268): Total length 1.37. Posterior sternal ridge less pronounced than in male, bearing only small tubercles. Posterior epigastric area with elaborate sclerotizations; posterior tube long, narrow.
