Specimen Labels

This species is known from several collections from lowland rain forests in Papua New Guinea. Its biology and nesting habits are unknown.


Relative eye length (eye length/head width) 0.35-0.42, occiput-ocular distance < 0.16, frontal lobes with a single erect hair, lateral areas of head weakly imbricate and with integument shiny, area between propodeal protuberances concave, bicolored with yellow head and thorax and dark brown gaster. The clypeus possesses between 14 and 20 erect hairs. This species superficially resembles T. pacifica or T. bidentata in color pattern but can easily be diagnosed with the above characters.
