2♂ (NHMSU), SINGAPORE: Bukit Timah Nature Reserve, Jungle Fall Stream, altitude 118 m, N1°21'25.4", E103°46'25.3", 21 August 2015, S. Li and Y. Tong leg.

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).

Description.

Male (holotype). Coloration: body and legs light brownish yellow.

Measurements: total length 0.78; carapace 0.46 long, 0.31 wide, 0.27 high; abdomen 0.48 long, 0.34 wide, 0.28 high; clypeus 0.10 high; sternum 0.23 long, 0.22 wide. 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).
