Diagnosis 
Eyes not hairy; metasomal bands broad; prominent 
supraclypeal area inclined relative to clypeus. Male scapes 
swollen (Fig. 5); supraclypeal area with dense hair. Female 
clypeus with coarse, dense punctures. 
Remarks. Michener (1965) gave detailed descriptions of 
this species as T. marginatulus. Similar to T. chrysostomus 
from which it is distinguished by slightly smaller size (length 
male c. 11 mm, female c. 11.5 mm), the presence of hair on 
supraclypeal area of male and the density of punctures on 
the clypeus of female. Male genitalia and hidden sterna (Figs 
40, 42, 73) are almost identical to those of T. chrysostomus. 
Distribution. Southeastern Australia between Brisbane and 
Adelaide (MDD, SB, SEQ) (Fig. 113).
