Maddison, WPM#05–036; 2 males, MALAYSIA: PAHANG: Cameron Highlands, Arcadia, Trail 3, 4.482° N, 101.388° E, elev. 1550 m, 21–23 May 2005, coll. W. Maddison, D. Li, I. Agnarsson & J. Zhang, WPM#05–033.

Etymology. Latin concava (concave), referring to the notch at the tip of the retrolateral tibial apophysis of the male palp.

Diagnosis. Could be recognized by the thick retrolateral tibial apophysis (thicker than those of Laufeia aenea Simon , see Prószyński 1976), the long and thin embolus of the male palp ( Figs 36–37 View FIGURES 34 – 42 ); the wide epigynal median septum and the presence of rim leading to the opening of copulatory duct of the epigynum ( Fig. 41 View FIGURES 34 – 42 ).

Description. Male (holotype, UBC-SEM AR00177). Carapace length 1.3 (variation: 1.1–1.3, n=6); abdomen length 1.2. Chelicera ( Figs 38–39 View FIGURES 34 – 42 ): dark brown; front surface with a longitudinal ridge; promargin and retromargin each with one bicuspid tooth. Palp ( Figs 36–37 View FIGURES 34 – 42 ): yellowish brown. Proximal tegular lobe present. Embolus relatively short and coiled for less a circle; embolic disc small, with a process along the embolus; retrolateral sperm duct loop occupying almost half of bulb width; retrolateral tibial apophysis short and wide, not reaching the distal end of tegulum, with a notch at distal end. First tibia with three pairs of ventral macrosetae; first metatarsus with two pairs of ventral macrosetae. Measurements of legs: I 2.6, II 2.0, III 2.1, IV 2.3. Color in alcohol ( Fig. 34 View FIGURES 34 – 42 ): carapace dark red brown, with many white scales; dorsal abdomen brown or gray brown with sandy yellow markings, with a relatively sclerotized area; ventral abdomen brownish; first two pairs of legs dark yellow brown, only coxa, trochanter and tarsus sandy yellow, last two pairs of legs sandy yellow, with brown annuli on tibia and metatarsus.

Female (paratype, UBC-SEM AR00178). Carapace length 1.2 (variation: 1.1–1.2, n=9); abdomen length 1.3. Chelicera ( Fig. 40 View FIGURES 34 – 42 ): promargin and retromargin each with one bicuspid tooth. First tibia with three pairs of ventral macrosetae; first metatarsus with two pairs of ventral macrosetae. Measurements of legs: I 1.9, II 1.8, III 1.8, IV 2.3. Epigynum ( Fig. 41 View FIGURES 34 – 42 ): window small with relatively wide median septum; opening to copulatory duct anterior lateral to window with rim. Vulva ( Fig. 42 View FIGURES 34 – 42 ): copulatory duct wide, spermatheca small and oval. Color in alcohol ( Fig. 35 View FIGURES 34 – 42 ): similar to that of male except legs paler in color.
