Description ( Roháček, 2006, 2009). Frons mostly dull, frontal triangle moderate or narrow, reaching to anterior half to third of frons; arista shortly ciliate or very densely haired to distinctly plumose; 2‒3 fronto-orbital setae developed. Mesonotum with 1 distinct presutural seta, 2‒3 dorsocentral setae and acrostichal microsetae in 4 (rarely 2) rows on suture. Legs mostly yellow, often with dark apical tarsal segments, rarely with femora somewhat darkened; fore femora with a ctenidial spine. Wing unicolourous, at most darkened at anterior margin; cross-vein r-m situated slightly proximal to or at middle of dm cell. Male genitalia: Epandrium moderate, as wide as high to strongly wider that high, with 1‒2 pairs of longer setae; hypandrium relatively robust, symmetrical and well sclerotized, with anterior inner lobes more or less developed; transandrium of various form, without or with (sometimes extremely robust) caudal process; pregonite fused with hypandrium, often with 1 ventrally projecting lobe and with 2 (anterior and posterior) groups of setae; postgonite slender, strap-like, with 1 anterior or lateral setula, usually in proximal half; aedeagus with short and rather simple phallophore; distiphallus composed of largely membranous saccus and usually long and more sclerotized filum; filum sclerotized, formed by single sclerite, most often slender and distally attenuated and paler-pigmented but its apex may be secondarily widened and armed by various teeth or projections; aedeagal part of folding apparatus with various structures externally and internally, usually spinose or tuberculate and striated; connecting sclerite usually distinct, rarely membranous; basal membrane usually densely spinose, unarmed when caudal process enlarged. Female abdominal tergite 8 usually narrow, elongate, sometimes strongly tapered posteriorly; sternite 8 longitudinally divided, in 2 often elongate sclerites, having posterior part more or less bent dorsally and recurved internally; genital chamber with single to 3 pairs of internal sclerites (often fused together, rarely asymmetrical) and with one curved and usually elongate (never transverse) annular sclerite; ventral receptacle very long, tubular and hyaline, with apex slender and curved, vermicular or helicoid; spermathecae (1+1) on long or very long ducts, subspherical to elongate pyriform, usually with transversely ringed surface and minute spinulae, often also with terminal invagination.

Remarks. The genus Anthomyza includes 43 species worldwide, of which 9 species are recorded in China. Roháček (2006, 2009) assembled part of them into 8 species groups. This genus is mainly distributed in the Palaearctic and Nearctic Regions, rarely Oriental and Neotropical Regions, but none in the Afrotropical or Australian Regions so far.
