Descriptions 
Male (holotype).— Head width 3.75 mm, body length 11.3 
mm. Relative dimensions: HW 50, HL 39, UID 33, UFW 33, 
LID 30, DMA 28, HVO 5, WOC 14, MOD 4, OOD 9, IAD 
8, ASD 3, AOD 9, ML 20, BMW 8, MSL 3.0, SL 14, SW 3, 
LL c. 42.— Eyes hairy; face broad, inner orbits converging 
ventrally; length of malar area c. 0.38x basal mandibular 
width; marginal area of clypeus elongated (laterally, 0.16x 
as long as medial length of clypeus); middle flagellomeres 
c. 1.2x as long as wide. Legs slender; hind tarsus as long as 
hind tibia; hind basitarsus 4.8x as long as wide; basitibial area 
strongly carinate on posterior margin, anterior margin with 
sharp edge. Genital capsule similar to that for T. orientalis 
n.sp. (Lig. 37); S7 (K.344818) with narrow rectangular lateral 
lobes and strong posterior projections (Lig. 78).— Distitarsi 
orange-brown; mandible deep orange-brown; labrum and 
flagellum ventrally brown. Tl-5 with wide, silver bands.— 
Clypeus dull, strongly pit-reticulate and densely punctate 
except apically; marginal area polished. Scutum dull with 
strongly pit-reticulation obscuring punctures.— Face densely 
covered with long, finely-branched, pale orange hair. Scutum 
closely covered with long, plumose, pale orange-brown hair; 
fore basitarsus with long, white plume; anterior margin of 
hind tibia with close to open fringe of long, white hair. 
Lemale (K.344819).— Head width 3.90 mm, body length 
11.0 mm. Relative dimensions: HW 50, HL 36, UID 31, 
ULW 33, LID 32, DMA 33, HVO 4, WOC 15, MOD 4, 
OOD 7, IAD 9, ASD 3, AOD 10, ML 20, BMW 7, MSL 1.5, 
SL 15, SW 3, LL c. 31.— Eyes hairy; face approximately 
quadrate, inner orbits parallel; length malar space c. 0.2x 
basal mandibular width; clypeus gently convex transversely; 
marginal area of clypeus as for male; middle flagellomeres 
as long as wide; inner hind tibial spur with c. 7 long teeth; 
apex of basitibial area not elevated above surrounding area; 
hind tarsal claw only with small inner ramus; pygidial plate 
entire, gently convex but without distinct medial elevation.— 
Distitarsi orange-brown; mandible deep amber. Tl-4 with 
silver bands of average width.— Clypeus strongly reticulate 
and densely punctate except at extreme ventral margin; 
frontal carina terminating in a small tubercle on supraclypeal 
area; scutal sculpture as for male.— Face with long, plumose, 
white hair, close on clypeus and supraclypeal area, dense 
in paraocular areas and on frons. Scutum closely covered 
with short, plumose, pale brown hair; metasoma sericeous; 
prepygidial fimbria pale brown. 
Remarks. Sexes associated by unique presence of labral 
tubercle and two coincident collection events. Similar to 
T. micans n.sp. but distinguishable by tubercle on labrum. 
Distribution. Western areas of southern Queensland and 
northern New South Wales (CP, ML) (Lig. 118). 
Etymology. The specific name is a Latin adjective meaning 
with a tubercle, referring to the labrum.
