Figures 761–794

TYPES: Male holotype and female allotype taken at an elevation of 900–950 m at Poring Hot Springs, Langanan Falls , Sabah (May 12, 1987; D. Burckhardt, I. Löbl), deposited in MHNG (PBI_OON 12215) .

ETYMOLOGY: The specific name is an arbitrary combination of letters.

DIAGNOSIS: Both sexes can easily be recognized by the posterolateral extensions on the posterior carapace margin (figs. 767, 779, 782, 783, 791); males have a bluntly tipped embolus (figs. 769–776) and females have a posterior notch in the posterior margin of the epigastric furrow (fig. 793) and a short, bifid posterior tube (fig. 794).

MALE (PBI_OON 12215, figs. 761–781): Total length 1.76. Carapace orange-brown, without any pattern; pars cephalica strongly elevated in lateral view; posterolateral edge with pair of pits, posterior declivity with distinct shoulders, tubercles not enlarged, but posterolateral edge of carapace with sharp tubercles, posterior margin squared, with paired dark triangular sclerotizations. Sternum covered with large round pits, with distinct posterior ridge. Scuto-pedicel region with deeply W-shaped scutal ridge bearing few tiny, sharply pointed tubercles opposite pedicel triangles set on anterolaterally enlarged pedicel margin. Palpal bulb dorsally scooped, with beaklike tip.

FEMALE (PBI_OON 12215, figs. 782– 794): Total length 1.76. Postepigastric region with weak, procurved ridge situated near epigastric furrow: posterior tube short, posteriorly widened.
