Brignolia rothorum , new species

Figures 295–306 , 309–332

TYPES: Male holotype and female allotype taken at an elevation of 7000 ft at Kodaikanal , 10u159N, 77u319E, Tamil Nadu, India (Dec. 30, 1989; V., B. Roth), deposited in CAS (38432, PBI_OON 2450) .

ETYMOLOGY: The specific name is a patronym in honor of the collectors of the type specimens.

DIAGNOSIS: Males resemble those of B. nigripalpis in having a proximally situated spur on the prolateral surface of the palpal cymbium (figs. 311, 316), but have the tip of the palpal bulb directed ventrally rather than dorsally; females can easily be recognized by the conformation of the epigastric region, which has a beaklike, posteriorly directed protrusion from the posterior margin of the epigastric furrow that almost meets an anteriorly directed, triangular posterior protrusion (figs. 328, 331, 332).

MALE (PBI_OON 2450, figs. 295– 306, 309–319): Total length 1.82. Carapace orange-brown, without any pattern; pars cephalica slightly elevated in lateral view; posterolateral edge with pair of pits, posteri- or declivity without distinct shoulders, top margin with two enlarged setae with enlarged bases on each side, posterior margin round- ed, with pair of slight darkenings opposite pits. Sternum covered with small round pits. Scuto-pedicel region with W-shaped scutal ridge almost straight, with slight tubercles. Palpal bulb elongated, middle part with recurved dorsal lobe, with blunt, ventrally directed tip.

FEMALE (PBI_OON 2450, figs. 320– 332): Total length 1.97. Epigynal area with relatively long, narrow, posteriorly directed scapelike projection originating near posteri- or margin of epigastric furrow, and relatively short, wide, anteriorly directed projection originating at middle of W-shaped transverse ridge situated near posterior spiracular groove; posterior tube curled.

OTHER MATERIAL EXAMINED: India: Tamil Nadu: Kodaikanal , 10u159N, 77u319E, Dec. 30, 1989, elev. 7000 ft (V., B. Roth, CAS 38432, PBI_OON 2450, 3 -, 10 U; below Kodaikanal, 10u159N, 77u319E, Dec. 31, 1989 (V., B. Roth, CAS 38475, PBI_OON 2449), 1 -, 2 U.
