Diapria Latreille, 1796: 110 .

Tropidopria Ashmead, 1893: 406 , 407, 416. An objective junior synonym of Diapria Latreille.

DIAGNOSIS (♀ 3): Medium­sized individuals (2.5–3.5 mm); body predominantly dark, appendages lighter, body smooth and shining, generally glabrous but with scattered semierect bristles and strong hairy cushions, foamy structures not developed; female antenna with moderate, semiabrupt, multisegmented clava (5–6), clavomeres not flattened ventrally, A12 without specialized pit; male A3–A14 strongly elongate, subcylindrical not knotted, with random erect hairs not in whorls; scutellar pit large and deep, often with longitudinal ridges; anterior margin of syntergite raised, flexed and excised medially; apical sternite in female vomeriform, sharply conical.

DESCRIPTION (♀ 3): HEAD. Globose head, frons unarmed, antennal shelf moderate, not margined posteriorly ; temple relatively large, rounded, anterior margin of antennal shelf only moderately projecting; level of toruli in middle of eye; eye subcircular, relatively small, posterior orbit of eye not sinuate, ommatidia small, nonconvex; ocelli normal; oral carina strongly developed; postgenal cushion strongly developed; occipital flange minute; mandible bidentate; clypeus with deep transverse sulcus above anterior margin, epistomal sulcus not developed, malar sulcus not developed, tentorial pits absent; hypostomal bridge well developed; papal formula 5–2; female antenna 12­segmented, with moder­ ate, semiabrupt, multisegmented clava (5–6 segments), clavomeres subspherical, with distinct gaps, clavomeres slightly higher than wide, not flattened ventrally, A12 ventrally with no pit; male antenna 14­segmented, long and slender, A3 to A14 strongly elongate, subcylindrical, not knotted, with random erect hairs not in whorls, A3 and A4 or only A4 modified, with longitudinal carina, A4 always emarginate, A1 distinctly longer than A3; special brushes on A8–A10 or A8– A12. MESOSOMA. Pronotum in dorsal view moderately developed, pronotal shoulders not developed, sides of pronotum flat, epomium not developed, anterior margin of pronotum and propleuron with massive cushions; mesoscutum moderately convex, with scattered semierect bristles, with no sulci, lines or depressions; anterior scutellar pit large and deep, often with longitudinal ridges; scutellar disc subrectangular, with strong median longitudinal keel; posterior margin of axilla moderately sharp, axillar depression with abundant appressed micropilosity; mesopleuron only slightly convex, with submedian oblique line rudimentary; sternaulus not developed; dorsellum densely hairy, with median keel stronger than lateral keels; metapleuron entirely covered with semiappressed silvery pilosity; propodeum rather short with distinct median keel raised medially, plica weakly developed, area between plica and keel hairy, posterior margin of propodeum V­shaped emarginate; wings always present, submarginal vein in forewing almost straight, reaching basal third of wing, stigmal vein rudimentary, basal vein not developed; submarginal vein in hind wing incomplete, indicated basally and apically near hamuli; legs generally slender, femora strongly, tibia moderately clavate distally, tarsi not compressed, apex of foretibia with long, slender spine dorsally. METASOMA. Petiole distinctly elongate, cylindrical, with irregular longitudinal keels and abundant pilosity both dorsally and ventrally; metasoma past petiole moderately convex, distinctly conical apically in female; anterior margin of syntergite raised, flexed, and excised medially; S2 basally with dense pilosity, specialized spot on S2 not developed, apical sternite in female vomeriform, sharply conical.

RECOGNITION AND RELATIONSHIPS: Diapria has been traditionally recognized on the presence of the median excision and flexion of the anterior margin of the syntergite. The ground plan of Diapria is essentially identical with that of Trichopria , s.l.; however, several minor details are worth mentioning. Contrary to some Trichopria , foamy structures and the specialized pit on female A12 never occur in Diapria and female clavomeres are not flattened ventrally. Sundholm (1960) discussed the taxonomy of Diapria and allied genera.

DISTRIBUTION: Notton (1995) recognized four species in Britain. Diapria conica (Fabricius) is a widespread tramp species occurring throughout the world. We also examined several specimens of Diapria from Chile (CNCI).

BIOLOGY: Diapria conica is a parasite of Eristalis tenax (L.) ( Syrphidae ) ( Sanders, 1911).
