Other species studied for comparison.

Sulaimania vigelandi (Fig. 28 A–E; Lehtinen, 1981: 51, figs 126-130, 133). Paratype 1♂ (NHMSU), MALAYSIA: Johor, Kota Tinggi District, Jalan Lombong, Biological Field Station, in litter of rain forest, 31 October to 4 November 1976, P.T. Lehtinen leg.

Etymology.

The specific epithet derives from the Latin word " brevis " = short, and refers to the short embolus; adjective.

Diagnosis.

This new species shares certain characteristics of the genus Sulaimania, including eye arrangement, habitus, and the general configuration of the male palp similar to that of the type species, Sulaimania vigelandi (see Fig. 28 D–E and Lehtinen 1981: 51, figs 126-130, 133). However, it may be distinguished from Sulaimania vigelandi by the shorter embolus without a bent embolic end (Fig. 27 F–H vs. Fig. 28 D–E and Lehtinen 1981: fig. 129), the larger body size, the oblong carapace (Fig. 22A vs. Fig. 28A and Lehtinen 1981: fig. 127), and the sternum with reticular margins (Fig. 22B vs. Fig. 28B).

Length of legs: I 0.78 (0.25, 0.10, 0.18, 0.12, 0.13); II 0.71 (0.22, 0.09, 0.15, 0.12, 0.13); III 0.61 (0.18, 0.08, 0.12, 0.11, 0.12); IV 0.80 (0.25, 0.08, 0.19, 0.14, 0.14). Leg formula: IV-I-II-III.

Prosoma (Fig. 27 A–D): finely reticulated at clypeus and thoracic margin; cephalic area flat and smooth, bearing several long setae; AME with black base, larger than PLE in size; clypeus sharply sloping anteriorly; sternum reticulated, marginally rugose, centrally smooth, covered with sparse long setae. Legs: cuticle striated; all tibiae with 3 trichobothria, but only one at each metatarsus.

Opisthosoma (Fig. 27 A–C, E): dorsal scutum long, oval, bearing short setae, anterior edge and center granulated; ventral scutum sparsely granulated, margin rugose; lateral scutum I short, perigenital scutum broad.

Palp (Fig. 27 F–H): femoral cuticle faintly striated, approximately 2.5 times as long as patella; patella short, length equal to width; tibia swollen, 2 times as long as patella, 1.5 times as wide as femur, with a dorsal-distal trichobothrium; bulb inverted pyriform, surface smooth; spermatic duct looming and spiral, basally wide, and gradually tapering to embolic tip (Fig. 22 F–G); embolus short, weakly sclerotized, starting from bulbous apex; embolic tip truncated, slight curving (Fig. 22 F–H).

Female. Unknown.
