Characteristics and taxonomy

The genus' species are diurnal and bilaterally symmetric. Its developmental mode is holometabolous. The body is robust and has a clypeus with the median lobe often unidentate or tridentate. The genitalia are short and wide. The harpe is curved inward.

The genus is primarily distinguished in males by a tergal process (metasomal tergal modifications/depressions/tubercles) on the second metasomal segment and a divided aedeagus in the male genitalia consisting of dorsal and ventral valvae.

Distribution

The genus is found worldwide, including Australasian, Nearctic, Neotropical, Afrotropical, Oriental and Palaearctic regions.
