New combinations 
Michener (1965) listed 21 names and Houston (1990) added 
two more. Of these names, four are synonymized and two are 
removed to other genera. T. rufus is removed to Leioproctus 
on the basis of (a) the pterostigma, which although short, 
is considerably longer and wider than in any Trichocolletes 
species, (b) the labrum which is short (0.2x as long as wide), 
(c) inner hind tibial spur, which is very long and uniform in 
width, not basally broadened as in Trichocolletes, (d) absence 
of translucent apical bands on metasomal terga, (e) polished 
area of propodeum and (f) very short first flagellomere. The 
hind basitibial plate is complete and carinate, albeit weakly 
pigmented, though this by itself would not be a reason to 
exclude the species from Trichocolletes. 
Trichocolletes rufopilosus is removed to Anthoglossa. The 
type specimen has been dissected by the original describer 
and the genitalia are mounted with the specimen. The greatly 
enlarged volsellae are typical of those found in Anthoglossa 
species and the type specimen was indistinguishable from 
an undescribed species of Anthoglossa commonly found 
in the Avon wheatbelt area of Western Australia. Males of 
this undescribed species have been collected with females 
having tridentate mandibles and other characteristics of 
Anthoglossa species.
