Galeopsomyia springerae Hansson sp.nov.

( Figs 190, 191 , 724 )

Diagnosis (female). Antennal clava with weak constriction between C1 and C2 ( Fig. 724 ); genal carina strong and reaching above level of lower eye margin; mesoscutellum ( Fig. 190 ) with strong reticulation, meshes elongate, submedian grooves weak but traceable, wide apart, slightly curved and diverging towards posterior part; propodeum ( Fig. 190 ) with median carina that splits in posterior part, like an inverted Y, raised in anterior part; hind coxa without carina along posterior margin; petiole transverse with strong sculpture; gaster ( Fig. 190 ) 2.5× as long as wide, medio-basal Gt 1 with a short rectangular incision; Gt 2 0.2× as long as Gt 4, Gt 1 with relatively weak reticulation, distinctly more shiny than remaining tergites.

Female holotype: length of body 2.4mm (paratypes 1.9–2.1mm).

Scape yellowish-brown, pedicel pale brown, flagellum dark brown. Frons metallic bluish-green, clypeus and antennal scrobes black; vertex metallic bluish-green. Mesoscutum and mesocutellum metallic bluish-purple with green tinges, propodeum golden-green. Legs with fore coxa metallic bluish, mid and hind coxae golden-green; trochanters dark brown, femora black with metallic tinges and with apex yellowish-brown; tibiae yellowish-brown; T1–3 yellowish-brown, T4 pale brown. Petiole black. Gaster with Gt 1 golden-green; remaining tergites black with metallic purple tinges; gonoplac black.

Antenna with a weak constriction between C1 and C2. Frons below eyes, clypeal area and toruli with weak reticulation, remaining parts with strong reticulation; with a long and strong genal carina. Vertex with strong reticulation.

Mesoscutum with strong reticulation, meshes isodiametric on sidelobes, elongate on midlobe; midlobe without a median groove, with 18 scattered adnotaular setae. Mesoscutellum with strong reticulation, meshes elongate; submedian grooves weak but traceable, wide apart, slightly curved and diverging towards posterior part; anterior pair of setae placed slightly in front of middle. Dorsellum with strong reticulation and median carina, not visible in dorsal view due to overhanging mesoscutellum. Propodeum with median carina splits in posterior part, like an inverted Y, anterior part raised; callus with two setae. Fore and mid coxae with weak reticulation, hind coxa with strong reticulation, hind coxa without carina along posterior margin. Fore wing with four setae on dorsal surface of submarginal vein; speculum open below; costal setal row unbroken.

Petiole transverse with strong sculpture on dorsal part. Gaster ovate-elongate; medio-basal Gt 1 with a short rectangular incision but without transverse edge or carina dorsally, with weak reticulation and shiny, remaining tergites with strong reticulation.
