An argument is made for the monophyly of the tribe Stenodemini China 1943 based on a character discussion treating the pretarsus, metepisternal scent efferent system, external cuticular ultrastructure, male and female genitalia, metafemoral trichobothria, and external morphology of head and pronotum. As a result, a proposal is presented to subsume Pithanini Douglas and Scott 1865 with Stenodemini. A cladistic analysis of the nominate stenodemine genera based on 54 characters is conducted. The revised Stenodemini includes 32 genera. The following junior subjective generic synonyms are proposed: Notostiropsis Poppius 1914 = Ebutius Distant 1909; Penacoris Cavalho and Rosas 1966 = Stenodema Laporte 1832; and Trigonotyliscus Carvalho 1975 = Trigonotylus Fieber 1858. A lectotype is designated for Ebutius bellus Distant 1909. Chaetomiris Bliven 1973 is treated as a nomen dubium. A key to the genera and a diagnosis of each recognized genus of the reconstituted Stenodemini are presented. A list of the included species, with a summary of their distributions based on faunal regions is given for each genus. Selected photomicrographs, scanning micrographs, and illustrations of structural features of stenodemine genera are provided.
