Several, but see text The Azelinini are a tribe of geometer moths in the subfamily Ennominae, with many species in the Southern Hemisphere, particularly in South America.

They rest with their wings stretched out parallel to the surface, and the hindwings hidden under the forewings unlike most related Ennominae.

The characteristic comb of transverse setae on the underside of the males' abdominal segment A3, found in many Ennominae, is apparently absent in the Azelinini, as is the associated "scent-brush" on the hindleg tibiae.

[1] The male genital's valvae usually have complex autapomorphic modifications (such as a hypertrophied ampulla and gnathos) in this tribe, but the valvula, like in their relatives, is not distally expanded.

Unusually, they have both an elongated uncus and well-developed socii;, the sacculus is rarely hairy and the saccus' vinculum is generally neither extended nor recurved.
