Type material. 1 M Holotype, MCSNG, Australia: Somerset, Cape York [Queensland], leg. L. M. D’Albertis.

Diagnosis. Male cheliceral promarginal teeth vary in size ( Figs 26 View FIGURE 26 B, D). Retromargins of unclear pattern, with 4–5 teeth. Frontal spurs conical ( Fig. 26 View FIGURE 26 B). Ventral spurs flat, small, located close to the proper retromarginal teeth ( Fig. 26 View FIGURE 26 D). Tegulum elliptic, narrow, embolus moderately long, arising at about 6 o’clock. Differs from other species by combination of palpal organ details and cheliceral armament.

Description. Male ( Fig. 26 View FIGURE 26 ) about 6 mm long. Cephalothorax moderately round (CW = 85 % of CL) and rather flat ( CH = 42 % of CL), light brown, covered with fine, pallid scales ( Figs 26 View FIGURE 26 A –C). Surrounding of eyes black. Clypeus very narrow, light brown, covered with sparse pallid setae ( Fig. 26 View FIGURE 26 B). Chelicerae pale brown, endites and labium orange-yelow, sternum relatively wide, yellow. Abdomen elongate, yellow with orange dorsal scutum, colour pattern rather indistinct ( Fig. 26 View FIGURE 26 A). Venter yellowish, with elongate stripes of small grey dots. Spinnerets yellow. Legs I brown, others orange-brownish. Palpal organ ( Figs 26 View FIGURE 26 E –G): tegulum elliptic, moderately narrow, embolus set distally, translucent part of spermophore not meandering, tibia 47 % of cymbium length, retrolateral tibial apophysis moderately long.

Dimensions. CL 2.40, CW 2.05, CH 1.00, AEW 1.40, PEW 1.50, EFL 0.85, AL 3.65, AW 1.55, L 1 7.55 (2.05 + 1.60 +2.00+ 1.25 + 0.65)
