Galeopsomyia cissusae Hansson sp.nov.

( Figs 80, 81 , 701 )

Diagnosis (female). Antennal clava solid ( Fig. 701 ); genal carina present; mesoscutellum ( Fig. 80 ) with strong reticulation, meshes elongate, submedian grooves indistinct, running parallel to lateral margins of mesoscutellum and thus diverging towards posterior part; hind coxa with a carina along posterior margin; gaster ( Fig. 80 ) 2.7× as long as wide, medio-basal Gt 1 with a sharp transverse edge dorsally, all tergites with strong reticulation.

Female holotype: length of body 2.2mm (paratypes 2.3–2.8mm).

Scape yellowish-brown, pedicel and flagellum dark brown. Face below level of toruli golden-green, clypeus dark brown, frons metallic bluish-green, antennal scrobes black; vertex metallic bluish-green. Thoracic dorsum golden-green. Legs with fore and hind coxae golden-green, mid coxa black; trochanters brown; femora dark brown to black with metallic tinges and with anterior part yellowish-brown; tibiae yellowish-brown; T1–3 yellowish-brown, T4 brown. Petiole black. Gaster with Gt 1 metallic bluish-green with posterior margin golden-purple, Gt 2-5 black with metallic purple tinges, Gt 6-7 metallic bluish-green; gonoplac black.

Antenna with solid clava. Head with strong reticulation, clypeus smooth, antennal scrobes with weak reticulation; with genal carina.

Mesoscutum with strong reticulation, meshes isodiametric on sidelobes, elongate on midlobe; midlobe with an indistinct median groove, with eight adnotaular setae. Mesoscutellum with strong reticulation, meshes elongate; submedian grooves indistinct, running parallel to lateral margins of mesoscutellum and thus diverging towards posterior part. Dorsellum with strong reticulation. Propodeum with triangular median carina; callus with two setae. Fore and hind coxae with strong reticulation, mid coxa with weak reticulation; fore coxa with a sharp edge along posterior margin and hind coxa with a strong carina along posterior margin. Fore wing with four setae on dorsal surface of submarginal vein; speculum open below and towards base of wing; costal setal row unbroken.

Petiole very short, just a narrow band. Gaster elongate; medio-basal Gt 1 with a sharp transverse edge dorsally; tergites with strong reticulation, Gt 1-4 with a smooth median line.
