A new genus, Femtapion (type species F. andersoni Kissinger, new species from central Mexico), is described in the tribe Aplemonini. Distinguishing features include body minute, globose, glabrous, polished; middle coxae not separated by union of median mesosternum and median metasternum; elytra lack humeri but (apparently) functional flying wings present; endophallus with coiled flagellum. The occurrence of a modified endophallic flagellum is unique in the New World Apioninae (with the exception of the Antilles). Perapion wickhami (Kissinger) is recorded from Scotts Bluff, Nebraska. Apion (Trichapion) memnonmonum Kissinger from North Carolina shows an unusual disjunct distribution. It is recorded on unopened flower buds of Amorpha sp. at 3 mi NE Angeles Oaks, camp Cedar Falls 6000', San Bernardino Co., California in June.
The dentifemur and venustula groups of the subgenus Homobezzia Macfie, genus Bezzia Kieffer, are represented in the Neotropical Region by 12 species. A key is presented for their identification, and to distinguish them from other groups of the subgenus Homobezzia. The two previously known species, B. venustula (Williston) and B. snowi Lane, are described and illustrated, as well as the following ten new species: aitkeni, bromeliae, cayoensis, dentifemur, filiductus, fusca, mexicana, nigritibialis, pseudovenustula, and raposoensis. Bezzia concoloripes Made is regarded as a junior synonym of B. venustula (Williston).
