Brignolia elongata , new species

Figures 725–760

TYPES: Male holotype and female paratype taken in primary forest at an elevation of 250–500 m in Gunung Gading National Park, near Lundu, 1u419170N, 109u519050E, Sarawak (May 30–June 1, 2007; A. Schultz), deposited in MHNG (PBI_OON 16112) .

ETYMOLOGY: The specific name refers to the highly elongated male and female genitalia.

DIAGNOSIS: This highly autapomorphic species has the most unusual genitalia in the group; both the male palpal bulb (figs. 733– 740) and the female genitalia (figs. 757–760) are highly elongated, so much so that the palpal bulb folds back on itself and the female genitalia extend almost the entire length of the postepigastric scutum.

MALE (PBI_OON 16112, figs. 725–745): Total length 1.47. 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 margin squared, with pair of dark triangular sclerotizations. Sternum covered with large round pits, with distinct posterior ridge. Scuto-pedicel region with deeply Wshaped scutal ridge, with single tubercle opposite area are of pedicel triangles, which are absent. Palpal bulb enormously elongat- ed, with reflexed, elongated dorsal extension.

FEMALE (PBI_OON 16112, figs. 746– 760): Total length 1.48. Genitalia enormously elongated, occupying most of abdominal length; posterior tube enlarged, elongated, reaching almost to rear of postepigastric sclerite.
