Diagnosis. CL 3.71–4.49. Separated from all species, except other northern Queensland species, by weakness of leg banding; from both T. lambkinae   and T. angusta   by the presence of a much shorter scape and a much larger RTA; from T. nasuta   by presence of scape.

f, epigynum ( S45531 View Materials ): c, ventral; d, lateral; e, posterior; f, dorsal—internal genitalia. Scale lines 0.5 mm: vertical,

a,b; horizontal, c–f.

Male (holotype). BL 8.90, CL 4.49 (3.71–4.49), CW 3.02, CapW 1.84, EGW 1.25, LL 0.69, LW 0.69, SL 2.12, SW 1.84. Legs: 2143 (I 21.00, II 21.17, III 15.67, IV 19.17); ratio tibia I length:CW = 1:0.56. Male palp: Fig. 15a,b. Cymbium wide with strongly developed retrolateral flange. Bulb wider than long; tegular lobe well developed, placed retrolaterally. Embolus origin retrolateral. Stem of T-shaped conductor prolaterally directed, posterior limb placed prolaterally; tegular window large, placed basally. RTA large, weakly dorsad, visible in ventral view; RVTA moderately broad, with blunt, beak-like apex turned toward upper side in ventral view.

Female ( S45531 View Materials ). BL 7.76, CL 4.08 (3.88–4.49), CW 2.61, CapW 1.92, EGW 1.10, LL 0.63, LW 0.63, SL 1.87, SW 1.55. Northern colour pattern.Legs: 1423 (I 14.08, II 12.08, III 10.00, IV 12.42); ratio tibia I length:CW = 1:0.75. Epigynum: Fig. 15c–e. 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. 15f.

Variation. Despite the fairly restricted distribution of this species, considerable variation was observed. Several specimens have been left unplaced until more comparative material is available. Male leg lengths vary from 1423, 1243 (legs 2 and 4 usually subequal) or less commonly 2143 (with 2 and 1 subequal). Females ( S42274 View Materials and S42275 View Materials ) from west of Bones Knob near Atherton have epigynal scapes shapes that are intermediate with T. angusta   ; females (KS58379 and KS58380) from Danbulla SF show epigyna intermediate with T. lambkinae   . A male specimen ( S42292 View Materials ) from Massey Creek, E of Ravenshoe, differs from other males in the conductor shape, position of RTA and larger size. However, females ( S42277 View Materials and S42278 View Materials ), from the same area, closely resemble the current species and are listed above.

Distribution. Ravenshoe area northwards to Cairns, northeastern Queensland.

Etymology. The specific name is in honour of Geoff Monteith, research entomologist and a collector of the type specimens.
