Diagnosis and Specialized Morphology
Species of Cetherinae are characterized by:
- short, transverse head
- vertex with transverse sulcus between compound eyes
- pedunculate eyes
Five genera and 23 species are recognized in the subfamily Cetherinae. The subfamily was first considered as a tribe within Reduviinae by Jeannel (1919). Putchkov & Putchkov (1985) elevated it to subfamily status and designated three tribes: Cetherini, Euphenini, and Pseudocetherini. A comprehensive treatment of the African fauna is provided by Villiers (1948).
Four genera of cetherines, including Cethera Amyot & Serville, are known from Africa and Madagascar; Eupheno Gistel occurs in the New World (Schuh & Slater 1995). Members of Cetherinae are active, and some are known to feed on termites (Miller, 1956a).
