Diagnosis 
Female (male unknown) eyes hairy; clypeus flattened; 
metasomal bands narrow, silver; supraclypeal area broad; 
lateral epistomal suture straight. 
Description 
Female (holotype).— Head width 4.20 mm, body length 12.1 
mm. HW 50, HE 36, UID 29, UFW 32, FID 31, DMA 31,

ME 19, BMW 7, MSF 2.0, SF 14, SW 3, FF c. 33 .—Eyes 
hairy; face wider than long; length malar space c. 0.25x basal 
mandibular width; clypeus protuberant, sagittally flattened or 
slightly depressed; basal suture shallow V-shape; basal width 
clypeus >2x length subantennal suture; supraclypeal area 
viewed laterally at distinct angle to base clypeus; epistomal 
suture between base of clypeus and base of mandible straight; 
distance from anterior tentorial pit to base of mandible 2x 
distance from pit to base clypeus; frontal carina ends in 
small tubercle on supraclypeal area; middle flagellomeres c. 
1.2x as long as wide; inner hind tibial spur with c. 7 teeth; 
tarsal claws simple; pygidial plate entire, flat medially.— 
Labrum, rim of clypeus, distal ends of femora and anterior 
surface of fore tibia orange-brown. Tl-4 with narrow silver 
bands.— Clypeus weakly reticulate with large punctures, 
dense medially, close laterally; scutum with dull sheen, 
strongly pit-reticulate with close, small punctures.— Face 
with pale orange-brown hair, darker near ocelli, sparse on 
clypeus and supraclypeal area, dense elsewhere. Scutum with 
close, plumose, orange-brown hair with dark tips; prepygidial 
fimbria dark brown or black. 
Remarks. Similar to T capillosus n.sp. from which it differs 
by the width of the supraclypeal area and to T. leucogenys 
n.sp. (see below). 
Etymology. The specific name is a Fatin adjective meaning 
from Dundas, an abandoned gold-mining town near one of 
the collection sites. 
Distribution. Southwestern Australia (AW, COO, MAE, 
MUR) (Fig. 92).
