Genus Chyromya Robineau-Desvoidy, 1830 View in CoL
Chyromya: Robineau-Desvoidy 1830: 620 View in CoL .
Type species: Chyromya fenestratum Robineau-Desvoidy, 1830: 621 [= Musca flava L., 1758], by monotypy.
Diagnosis: Broad fr, parallel sides or sides only slightly convergent anteriorly; in profile, gena recessed relative to projecting fr, and head generally higher than long; eye round and ocp clearly convex whether viewed from above or in profile; ocp setae and/or setulae scattered over whole disc, sparing only strip from vertex to short distance above occipital foramen; scutum with setulae scattered among strong setae; acrs rows irregular, composed of similar setulae; prscut pair stronger; pra and post ia setae absent, instead there are setulae of similar length to those on rest of scutum; scut with additional marginal setae to usual two pairs (basal and subapical); wing long, with discal cell being longest in family, thus length of vein separating basal and discal cells at least 2.5 times as long as apical section of M–Cu; posterior crossvein at middle or beyond middle of wing when measured from hu crossvein to apex; femora, especially fore and hind pairs in males, often strongly swollen; apicoventral seta on mid tibia absent.
Distribution: Holarctic. No species that corresponds to the genus as defined here has yet been found in the Afrotropical Region. However, in the Canary Islands, and coastal regions of North Africa, the following Palaearctic species do occur and their distribution may extend further south: flava (L., 1758); intermedia Ebejer, 2001; and robusta Hendel, 1931 . These are not treated further in this paper.
Ecology: Compared to other genera, Chyromya species are encountered more frequently in open broadleaved woodland, parks and gardens. In the warmer parts of temperate regions, population densities can be high, but usually not as high as populations of Aphaniosoma and Gymnochiromyia . There are more records of an association with bird and especially mammal nests and burrows in Chyromya than in other genera of this family.
