Batley & Houston: Australian bee genus Trichocolletes 
31 
dense in paraocular areas and on frons, sparse on clypeus 
and supraclypeal area. Scutum densely covered with short, 
plumose, brown hair, tipped with dark brown; metasoma 
sericeous with semi-adpressed golden pubescence; tibial 
scopa dark brown; prepygidial fimbria orange-gold. 
Remarks. This species can usually be distinguished from T. 
centralis n.sp. by its darker colouration, but males also have 
features not found in T. centralis n.sp.: a projection on the 
fore trochanter, and mid femur incrassate and a conspicuous 
brush on the anterior margin the mid basitarsus. Females 
differ from T. centralis n.sp. mostly by colour but also by 
the simple hind tarsal claw. 
This species is referred to as F256/M230 in Houston (2000). 
Distribution. Inland parts of southwestern Australia (AW, 
MAL, COO) (Fig. 108). 
Etymology. The specific name is a Latin adjective meaning 
brilliant or beautiful, referring to the conspicuous bright gold 
metasomal bands.
