Genus Carpophthoromyia Austen

Carpophthoromyia Austen, 1910: 71 . Type species: Musca vittata Fabricius , by original designation.

Diagnosis

Carpophthoromyia can be separated from closely related genera by the combination of the following diagnostic characters: anepisternum with oblique white line along posterodorsal portion; two anepisternal setae; scutum with dark brown to black ground colour, often with transverse band(s) of silvery setulae; scutellum flattened, ground colour white, with or without apical spots; wing with dark brown base and banding consisting mainly of an S­band and inverted V­band (see above).

Description

Head. First flagellomere twice to three times as long as pedicel; yellow or orange to brown; rounded apically. Arista variable, from short­pubescent along entire length to distinctly plumose. Face and frons white or yellow. Chaetotaxy: major setae black and acuminate; two orbitals, anterior orbital thicker and longer than posterior orbital; three (rarely two) frontals, usually of increasing length from anterior to posterior frontal; one pair of ocellars, as long as or longer than anterior orbital; medial vertical almost twice as long as posterior orbital, lateral vertical equal to anterior orbital seta; postocellar black, shorter than lateral vertical; postoculars slender and short, black. Genal setulae usually well developed, black. Genal seta black. Other setae and setulae short and black or whitish yellow.

Thorax. Postpronotal lobe white to pale yellow, rarely pale brown. Scutum shining brown to black, with short dark setulae; often with 1–2 transverse bands of denser silvergrey setulae and microtrichosity. Scutellum flattened, either completely white to pale yellow, or with brown to black apical marking(s). Subscutellum entirely black. Anepisternum posterodorsally white, white area usually touching postpronotal lobe and upper margin, ventrally running obliquely towards and reaching posteroventral corner or almost so, anteroventrally brown to black, with pale and dark setulae. Katatergite and anatergite partly or wholly white to yellow. Chaetotaxy: setae on scutum normal in shape and black; two scapulars, one postpronotal, two notopleurals, one presutural supra­alar, one dorsocentral, one postsutural supra­alar, one postalar, one intra­alar, one prescutellar acrostichal, one basal and one apical scutellar, two anepisternals, one anepimeral, and one katepisternal.

Legs. Yellow to brown­black. Setae black, setulae yellow to black. Midtibial spur black.

Wing ( Figs. 1–12 ). Vein R4+5 dorsally sparsely setulose on basal two­thirds. Vein M reaching costa posterior to wing apex. Cell bcu with posterodistal lobe sinuous. Wing largely dark brown, globally with dark base, S­band and inverted V­band (see above); pattern of latter bands variable. Usually one or two hyaline indentations along anterior margin of wing.

Abdomen. Ground colour usually brown to black; with black setulae, along posterior margin of tergites usually with longer setae. Tergites 2 and/or 4 often with paler transverse band. Oviscape orange to brown, variable in length; with short, dispersed yellowish or blackish setulae. Aculeus either round and tubular or flattened; aculeus tip pointed in the tubular forms, variable in shape in the flattened forms. Two spermathecae, ovoid or cylindrical ( Figs. 36–38 ).
