ferruginous across anterior third.— Clypeus densely 
punctate on a strongly reticulate ground; scutal sculpture 
as for male.— Face covered with long, plumose, white hair, 
dense on frons and in paraocular areas, close on clypeus and 
supraclypeal area. Scutum closely covered with moderately 
short, plumose, pale brown hair; scopal hair off-white; 
golden brown setae in basitibial area; metasoma sericeus 
as for male; fimbria light brown. 
Remarks. Similar to T. brunilabrum n.sp. and T. lacaris 
n.sp., from which males may be distinguished by the 
shape of S7. Females differ from T. brunilabrum n.sp. by 
the finer clypeal sculpture and from T. lacaris n.sp. by 
the presence of an i nn er ramus on hind tarsal claw. This 
species is superficially similar to T. tuberatus n.sp., with 
which it may be sympatric, but is easily distinguished by 
its smooth labrum. 
Etymology. The specific name is a Latin adjective meaning 
glittering, referring to the metasoma which is conspicuously 
reflective when the insects forage in direct sunlight. 
Distribution. Inland New South Wales and South Australia 
(BBS, DRP, FLB, SEQ) (Fig. 106).

Trichocolletes (Trichocolletes) multipectinatus Houston, 
1990, p. 618. 
Diagnosis 
Eyes not hairy; proboscis relatively elongate, prementum 
length at least 3.5x eye width viewed laterally. Female 
lower clypeus dull, densely punctate; facial hair brown, 
simple; mid-tibial spur strongly curved with set of stout 
teeth medially; prepygidial fimbria orange or mostly so. 
Male with hair of clypeus very erect, of even length, 
appearing cropped; fore basitarsus expanded ventrally; 
fore calcar without teeth; T7 with only a medial spot 
yellow-brown. 
Remarks. Exhibits a preference for flowers of Eremophila. 
Detailed descriptions can be found in Houston (1990). A 
more recently collected specimen ($, Wilcannia [31.6742°S 
143.4664°E], 28 Sep. 2003, M. Batley, ex Eremophila sturtii, 
AM [K.316532]) extends the known range eastward. 
Distribution. Southern Western Australia (Mt Magnet - 
Kalgoorlie region), northern Eyre Peninsula, South Australia 
and western New South Wales (COO, DRP, GAW, MUR, 
YAL) (Fig. 107).
