Sobarocephala (Diptera: Clusiidae: Sobarocesphalinae)—Subgeneric classification and Revision of the New World species

Sobarocephala Czerny is divided into nine newly erected species groups: the S. archisobarocephala (4 spp.), S. erwini (3 spp.), S. flava (8 New World spp.; 2 Old World spp.), S. flaviseta (86 New World spp.; 1 Old World sp.), S. interrupta (86 spp.), S. isla (25 spp.), S. latipennis (16 spp.), S. plumicornis (9 Old World spp.), and S. ruebsaameni (11 spp.) groups; 1 species (S. setulocetra spec. nov.) remains unplaced. There are 240 species of Sobarocephala in the New World, including 17 Nearctic (2 extend into the Neotropical Region) and 170 new species, some of which were previously considered varieties of S. humeralis Melander & Argo. The Neotropical fauna is here described, illustrated, keyed, and placed in a phylogenetic context. Sobarocephala peruana Soós stat. nov., formerly a subspecies of S. nigronota Melander & Argo, is raised to the species level, S. imitans Curran syn. nov. and S. diversipes Curran syn. nov. are synonymized with S. liturata Melander & Argo, S. annulata albiventris Soós syn. nov. is synonymized with S. annulata Melander & Argo, S. albitarsis Czerny syn. nov. is synonymized with S. humeralis, and S. pruinosa pallidor Steyskal syn. n. is synonymized with S. pruinosa Soós. Lectotypes are designated for S. bistrigata (Kertesz) , S. lumbalis Williston, S. plumicornis Lamb and S. variegata Melander & Argo. The egg of S. uberis spec. nov. is described.
