Leichhardteus bimaculatus Baehr & Raven, 2013: 354 , figs 2C, 6A–H, 11.

Diagnosis. Males differ from those of L. kroombit in the lateral bulge on the palpal femora, a deeper groove in between distal embolus ridges, the abdomen with three white spot pattern dorsally, and three large white slashes laterally, and distinct distal bands on femora II–IV. Female unknown.

Supplementary description holotype male QM S14709 . Carapace 3.23 long, 2.28 wide. Total length 6.5.

Colour: abdomen dorsally black brown with paired irregular oval areas medially and white spot just above spinnerets, laterally with two large contiguous white spots near trochanter IV, posteriorly a large and small white curved tapering slash; ventrally, genital scute orange brown, medially a light brown rectanguloid bounded laterally by a series of white spots, anteromedially a pallid area. Carapace: finely rugose, almost glabrous with serrate or pustulose margin; fovea short, near coxae II/III. Fine hairs laterally on caput with long incurved bristles on clypeus. Chelicerae: with distinct produced fang shield; 3P, 2R, middle largest. Maxillae: with distinctly elevated long ovoid rugose mound for half ventral length. Legs: RCH basal, small, distinct. Coxae II–IV with distinct anterior basal process. Lightly pustulose. Feathery hairs not evident. Trochanters with short shallow notches. Lightly setose. Spines: as for L. conopalpis , but on tibiae and metatarsi spines strong paired, slightly overlapping on tibiae, otherwise: I: fe p1d2. II: fe p1d2; ti p2. III: fe p2d3r2; ti p2d2r2. IV: fe p2d3r1; ti p2d2r2. Palp: fe p1d2; ti proventral 1 long basal. Claws: with tufts larger on IV than on I; tufts shallow but high, claws just lower than dentate claws. Abdomen: scutes: dorsal darkly sclerotised and narrow for 3/4 length; no ventral; genital, strongly sclerotised with thick anterior edge but no collar; tracheal, broad triangular, spiracle marked by short procurved slit. Genital aperture marked by wide sclerotised rectangle. Pedicel: sclerotised dorsally with two transversely banded edges off abdomen. Two long bristles project forward from abdomen just above pedicel. Spinnerets: small triangular setose colulus. PLS less than half diameter of ALS. Palp: femur subdistally incrassate, bulge more prominent retrolaterally, most evident viewed ventrally; bulb like L. kroombit but with deeper groove between distal embolic ridges; cymbium like L. kroombit .

Distribution and Habitat. Known only from rainforest at Conway Range National Park, mideastern Queensland.
