Diagnosis. Middle-sized (3.5–5.0 mm) fruit flies with 3 frontal and 2 orbital setae, pale postocellar seta, variable shape of head, antenna and proboscis (short with flat, slightly receding or vertical face, apically pointed flagellomere 1 and short labellum, as on figs 2, 2–4 , in Carpomya s. str. and Myiopardalis and long, with carinate, anteriorly produced face and long, geniculate proboscis as on fig. 2 , 1 , in Goniglossum ), usually brightly patterned, pale yellow to orange mesonotum with shiny black spots and grey microtrichose areas (if, in C. incompleta uniformly pale reddish yellow and microtrichose, then flagellomere 1 pointed and ocellar setae short), long and strongly acute posterior lobe of surstylus of male, oviscape with T-shaped desclerotized posteromedial area ventrally, and aculeus either uniformly tapered apically (in Carpomya s. str. and Myiopardalis ) or abruptly cut into a wide, serrate apex in Goniglossum (see Freidberg, 2016). Third instar larva with a few (3–4) serrate oral ridges and stomal sensory organ with strong preoral teeth.

Remarks. Carpomya shows no significant differences from the largest genus of Carpomyini , Rhagoletis , except for the mesonotal pattern as on figs 1, 1 , 3, 1–3, 3 and 3 , 5 (though C. incompleta has uniformly pale reddish yellow mesonotum, as in some Rhagoletis and can be distinguished from them only by having short ocellar seta, which is long in all Rhagoletis ) species.

Neither Carpomya nor Rhagoletis have been definitively proven to be monophyletic (V. Korneyev, unpublished data; J. Jenkins, unpublished data; J. Smith et al., in prep.): Carpomya is either the sister-group of Rhagoletis , or an in-group within the species assigned to Rhagoletis . Taxonomic consequences and concepts of both genera likely will be influenced by the results of forthcoming phylogenetic analyses based on the sequences of multiple genes (J. Smith et al., in prep.), and we abstain from any taxonomic changes (including those by Freidberg, 2016) until their phylogenetic relationships are more clearly resolved.
