REVISIONARY ^OTES ON NORTH AMERICAN TEPHRITIDAE (DIPTERA), WITH KEYS AND DESCRIPTIONS OF NEW SPECIES George C. Steyskal and Richard H. Foote Systematic Entomology Laboratory, IIBIII, Agr. Res. Serv., USDA^ ABSTRACT — Orcllia undosa ( Coti. ) is transferred to Chaetostomella Hendel; San Diego, CA specimens of Cnjptotreta pallida (Cole) of Blanc and Foote are redescribed as C. cislimitensis Steyskal, n.sp.; Rhagoletoides Foote is made a new synonym of Oedicarena Loew, and a new key to the species of the latter is pre-sented; Eurosta floridensis Foote, n.sp., is described from Jasper and Orlando, FL, and a key to Eurosta spp. is presented for the first time; Valentibulla steyskali Foote, n.sp. is proposed for the concept assigned to Valentibulla inunda (Coq.) by Foote and Blanc 1959, and a new key to the species of Valentibulla is provided. This paper includes descriptions of several new species belonging to various New World genera of Tephritidae and presents necessary changes in the nomenclature of several taxa to bring the use of sev-eral names into conformity with the Manual of North American Diptera soon to be published by Agriculture Canada. We also present keys to the species of some genera for which published revisions have never been available, and we have updated others to make them more useful in the light of recent taxonomic developments. The research reported herein is in large part that of the senior author; the junior author reviewed, concurred in, and edited the manuscript, and provided the description of one new species in a very minor way. Both authors are deeply pleased to honor Alan Stone with this contribution to the published record of a family to which he made important taxonomic contributions. Genus Chaetostomella Hendel Chaetostomella Hendel, 1927: 21, 124. Type-species, Tnjpeta onotrophes Loew, 1846, by original designation. In the American fauna, this genus finds its place with a small group of non-dacine and non-myopitine genera characterized as follows: dorsocentral bristles anterior to halfway between supra-alar and acrostichal bristles; scutellum not distinctly swollen nor polished; posterior upper fronto-orbital bristles convergent. This group includes also Orellia Robineau-Desvoidy and Neaspilota Osten Sacken, from both of which it may be easily distinguished by a few well-developed setae on the anterior oral margin that are larger than adjacent setae. Only the following species is known from North America. ^ Mail address: c/o U. S. National Museum, Washington, D. C. 20560. 146
