Galeopsomyia transcarinata (Gahan), (LaSalle 1994:176).
Diagnosis (female). Antennal clava solid (Fig. 681); lateral ocelli close to eyes, POL 1.7× OOL; mesoscutellum (Fig. 680) with median part with very weak reticulation and shiny, lateral parts with strong reticulation and with white setae scattered all over parts, submedian grooves indistinct; dorsellum with median carina; propodeal callus with ten setae; medio-basal Gt 1 with carinae laterally, absent dorsally (Fig. 680).
Female paratype: length of body 1.9mm.
Scape yellowish-brown, pedicel pale brown, flagellum dark brown. Head with frons metallic bluish-green, clypeus dark brown, antennal scrobes black; vertex metallic bluish-purple. Thoracic dorsum metallic bluish-green. Legs with coxae metallic bluish-green; trochanters pale brown; femora metallic bluish-green with apex yellowish-brown; tibiae yellowish-brown; T1–3 yellowish-brown, T4 brown. Petiole black. Gaster with Gt 1,6,7 metallic bluish-green, Gt 2-5 golden-purple; gonoplac yellowish-brown.
Antenna with a weak constriction between C1 and C2. Face below level of toruli with weak reticulation, clypeus smooth, frons rugose, antennal scrobes with weak reticulation; with a short and weak genal carina close to mouth opening. Vertex with weak reticulation outside ocellar triangle, with wrinkled sculpture inside ocellar triangle; with a carina between posterior ocelli in posterior part.
Mesoscutum with strong reticulation, meshes isodiametric on sidelobes, elongate on midlobe; midlobe with a weak median groove, and with ten scattered adnotaular setae. Mesoscutellum with weak reticulation on median part and without median groove, lateral parts with strong reticulation, meshes elongate; submedian grooves distinct, straight and diverging towards posterior part, outer margin indistinct in anterior half; with ten setae scattered over lateral parts. Dorsellum with weak sculpture, with median carina. Propodeum with a strong median carina that is gradually expanding towards posterior part; with strong irregular carinae; callus with ten setae. Fore and hind coxae with strong reticulation, mid coxa with weak reticulation. Fore wing with 4&5 setae on dorsal surface of submarginal vein; speculum open below; costal setal row unbroken.

Male. Unknown.
Hosts. Reared from galls induced by the alfalfa gall midge, Asphondylia websteri Felt (Diptera: Cecidomyiidae) (Gahan 1919). The host plant in Arizona was undoubtedly alfalfa (Fabaceae: Medicago sativa), although the flower-fruit galls produced by A. websteri have subsequently been reported from other Fabaceae and even a species of Simmondsiaceae (Gagné & Wood 1988). The latter authors report Galeopsomyia sp. from A. websteri galls on Parkinsonia aculeata (Fabaceae).
Distribution. U.S.A. (Arizona) (Gahan 1919).
Material examined. Holotype female examined through images; paratype female in NHMUK.
