Brignolia ratnapura , new species Figures 269–294

TYPES: Male holotype and female allotype from the Sinharaja Forest Reserve, Ratnapura, Sri Lanka (Aug. 23, 1981), deposited in NML (PBI_OON 514).

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

DIAGNOSIS: Although taken sympatrically with B. sinharaja , this species is much more closely related to B. parumpunctata . Males share with that species a rounded dorsal protrusion on the palpal bulb, but have the protrusion less coiled as well as a longer, narrower tip on the bulb (figs. 277–280). Females share with that species a twisted posterior duct (fig. 294), but lack an external epigastric protrusion (fig. 293).

MALE (PBI_OON 514, figs. 269–284): Total length 1.28. Carapace pale orange, without any pattern; pars cephalica strongly elevated in lateral view; posterolateral edge without pits, posterior declivity steep, top margin with three enlarged setae with enlarged bases on each side, posterior margin rounded. Sternum covered with small round pits. Scuto-pedicel region with deeply Wshaped scutal ridge, thinner at middle but still distinct, without tubercles. Palpal bulb taper-

ing apically, middle part with rounded dorsal process.

FEMALE (PBI_OON 514, figs. 285–294): Total length 1.32. Posterior genitalic tube convoluted, thicker anteriorly than posteriorly.

OTHER MATERIAL EXAMINED: None.

DISTRIBUTION: Sri Lanka.
