Diagnosis. CL 2.98–4.78. Separated from all species, except other northern Queensland species, by weakness of leg banding; from T. monteithi by greater length of scape and smaller RTA; from T. lambkinae by lesser width of scape and relatively narrower cymbial flange width; from T. nasuta by presence of scape.

ventral; d, lateral; e, dorsal—internal genitalia. Scale line 0.5 mm.

Male (holotype). BL 6.57, CL 3.22 (2.98–3.67), CW 2.37, CapW 1.43, EGW 0.92, LL 0.49, LW 0.49, SL 1.59, SW 1.39. Legs: 1423 (I 16.33, II 14.67, III 11.67, IV 14.83); ratio tibia I length:CW = 1:0.57. Male palp: Fig. 14a,b View Figure 14 , KS58195. Cymbium wide with strongly developed retrolateral flange. Bulb subcircular; 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 short, dorsad, mostly hidden in ventral view; RVTA broad, width about one-third tibial length, with beaklike apex turned toward upper side in ventral view.

Female ( S42271 View Materials ). BL 7.84, CL 3.84 (3.35–4.78), CW 2.24, CapW 1.80, EGW 1.10, LL 0.59, LW 0.57, SL 1.71, SW 1.43. Northern colour pattern. Legs: 1423 (I 12.92, II 11.33, III 9.25, IV 11.50); ratio tibia I length:CW = 1:0.65. Epigynum: Fig. 14c,d View Figure 14 . Scape relatively narrow, sides subparallel, distally truncate, at least half of scape projecting behind level of epigastric groove; in side view distoventral scape curved inwards, not protuberant; epigynal fossae oriented diagonally. Internal genitalia: Fig. 14e View Figure 14 .

Distribution. From the Windsor Tableland northwards to Helenvale, south of Cooktown, northeastern Queensland.

Etymology. The specific name means “narrow” (L.) and refers to the width of the female scape in comparison to the other north Queensland species.
