Hormorini

Hormorini can be distinguished from other Entiminae tribes by the broad, unconstricted connection between the rostrum and head. The scrobe (groove housing the antenna) is usually well-developed and visible. Body form varies among genera but generally follows the broad-shouldered, rounded shape common to many Entiminae. Antennal insertion is typically near the middle of the rostrum. Specific identification to genus requires examination of genitalia and other fine structural details.

The tribe has a wide geographic distribution with genera recorded from North America, South America, Africa, Madagascar, and various oceanic islands. The genus Hormorus occurs in North America. Several genera including Andringitrabius, Esmelina, and Genavius are endemic to Madagascar. African distribution includes genera such as Evas and Guineobius. The genus Styliscus has been recorded from the Hawaiian Islands.

• other Entiminae tribesHormorini shares the broad rostrum-head connection with many Entiminae, but differs from tribes such as Naupactini (which often have a more constricted rostral base) and Eustylini (which typically show different antennal club structure). Geonemini and Peritelini also differ in rostral proportions and scrobe development.
