Figures 691–724

TYPES: Male holotype and female allotype taken in primary forest at an elevation of 600–800 m in Gunung Gading National Park, near Lundu, 1u429500N, 109u509090E, Sarawak (May 28, 2007; A. Schultz), deposited in MHNG (PBI_OON 16090) .

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

DIAGNOSIS: Males can easily be recognized by the horn-shaped dorsal protuberance on the palpal bulb (figs. 699–704), females by the tiny epigastric scape protruding from the posterior margin of the epigastric furrow (figs. 723, 724).

MALE (PBI_OON 16090, figs. 691–711): Total length 1.36. 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 two dark triangular sclerotizations. Sternum covered with large round pits, with distinct U-shaped posterior ridge. Scuto-pedicel region with Wshaped scutal ridge divided into two rounded halves, each with transverse row of small tubercles opposite pedicel triangles. Palpal bulb abruptly narrowed basal to long, recurved horn-shaped dorsal lobe, with prolateral spike at tip.

FEMALE (PBI_OON 16090, figs. 712– 724): Total length 1.37. Postepigastric region with short, narrow epigastric scape anterior of deeply depressed atrium, atrium bordered posteriorly by anteriorly directed, triangular protrusion originating near posterior spiracular groove; posterior tube relatively short, triangular.
