Diagnosis. CL 2.94–4.69. Separated from all species, except other northern Queensland species, by weakness of leg banding; from T. monteithi by larger size of scape and

smaller RTA; from T. angusta by greater width of scape and relatively wider cymbial flange; from T. nasuta by presence of scape.

Male (holotype). BL 6.78, CL 3.59 (2.94–4.69), CW 2.45, CapW 1.51, EGW 0.94, LL 0.55, LW 0.53, SL 1.84, SW 1.47. Legs: 1243 (I 17.42, II 15.83, III 12.67, IV 15.50); ratio tibia I length:CW = 1:0.55. Male palp: Fig. 13a,b View Figure 13 . Cymbium wide with strongly developed retrolateral flange. Bulb wider than long; tegular lobe placed retrolaterally, with prominent conical base. Embolus origin retrolateral. Stem of T-shaped conductor prolaterally directed, posterior limb placed prolaterally; tegular window large, placed basally. RTA dorsad, hidden in ventral view; RVTA broad, width about half tibia length, with beak-like apex turned toward upper side in ventral view.

Female ( S45528 View Materials ). BL 7.35, CL 3.47 (3.27–4.29), CW 2.20, CapW 1.67 EGW 0.98, LL 0.55, LW 0.55, SL 1.63, SW 1.31. Northern colour pattern. Legs: 1423 (I 12.25, II 10.50, III 8.67, IV 10.67); ratio tibia I length:CW = 1:0.71. Epigynum: Fig. 13c,d View Figure 13 . Scape wide, sides gently concave, most of scape placed behind level of epigastric groove; in side view distoventral scape curved inwards, not protuberant; epigynal fossae oriented diagonally. Internal genitalia: Fig. 13e View Figure 13 .

Variation. Epigynal scapes vary in width, the widest being those from Mt Lewis and near Lake Barrine.

Distribution. Northeastern Queensland from the Townsville region northwards to the Daintree region.

Etymology. The specific name is in honour of Christine Lambkin, the illustrator of the type specimens.
