Brignolia assam , new species

Figures 587–610

TYPE: Male holotype taken at an elevation of 200 m at Manas, Assam, India (Oct. 23, 1978; C. Besuchet, I. Löbl), deposited in MHNG (PBI_OON 12832) .

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

DIAGNOSIS: Males can easily be recognized by the translucent and distally curved ventral protrusion at the tip of the bulb (figs. 595, 597). No significant differences have been detected between the holotype from India and the male from Nepal that is here also assigned to the species (figs. 599, 601).

MALE (PBI_OON 12832, figs. 587–610): Total length 1.93. Carapace orange-brown, without any pattern; pars cephalica strongly elevated in lateral view; posterolateral edge with pair of pits, posterior declivity with distinct shoulders, but tubercles not enlarged, posterior rim squared, with pair of lateral sclerotizations. Sternum covered with small round pits, with distinct, U-shaped posterior ridge. Scuto-pedicel region with deeply Wshaped scutal ridge only slightly less sclerotized near midline, without tubercles. Palpal

bulb tip with translucent ventral extension bearing dorsally curved tip.

FEMALE: Unknown.

OTHER MATERIAL EXAMINED: Nepal: Nuwakot District: Trisuli, July 21–22, 1983, forest remnant, elev. 600–650 m (J. Martens, W. Schawaller, NMB PBI_OON 15742), 1 -.
