The Neotropical Predaceous Midges of the genus \u3ci\u3eBezzia\u3c/i\u3e (Diptera: Ceratopogonidae) Part IV. The \u3ci\u3edentifemur\u3c/i\u3e and \u3ci\u3evenustula\u3c/i\u3e Groups

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)
