Tribe DIACHLORINI

In addition to the absence of setulae on the basicosta, females generally have the frons parallel or distinctly divergent, the antennal scape not tending to develop into a hood over the pedicel, the palpi more or less swollen basally and tapered gently to a rounded apex, and the proboscis relatively stout and with relatively large labella. The eyes of the females are rarely banded or bicoloured; those of males are often markedly inflated, with the enlarged upper facets especially prominent. Otherwise, sexual dimorphism is rarely notable. In general habitus the species tend to be less robust than most Tabanini . The larvae tend to be less torpedo-shaped and have far less prominent pseudopodia than larvae of Australian Tabanini .
