( Figs 18 View Figure , 33 View Figure , 101–103 View Figure )

Comparison. Gauldiana minuta  may be distinguished from others species of this genus by its short black antenna with only 13–14 flagellomeres ( Fig. 101 View Figure ), and the short and strongly upcurved ovipositor ( Fig. 103 View Figure ).

Description. Female. Small species. Body length 2.4 mm. Fore wing length 2.1 mm.

Head in dorsal view with gena somewhat shorter than eye width. Antennal flagellum distinctly clavate, with 13–14 flagellomeres ( Fig. 101 View Figure ); subbasal flagellomeres 1.6–1.8× as long as broad, and subapical flagellomere square. Clypeus lenticular, apically truncated, smooth with upper margin finely granulate. Malar space short, 0.4– 0.5× as long as basal mandibular width.

Mesosoma with notaulus absent or as very fine wrinkle. Propodeum with transverse carina very weak, medially obliterated, basal part 0.8× as long as apical area, and apical area about 1.8× as long as maximally broad ( Fig. 102 View Figure ). Propodeal spiracle separated from pleural carina by about 2.0× diameter of spiracle.

Fore wing ( Fig. 18 View Figure ) with vein R1 not reaching apex of the wing. Vein 2m-cu weakly to distinctly postfurcal. Vein 2rs-m short and thick. Postnervulus intercepted near centre, its posterior abscissa pigmented or unpigmented. Hind wing with vein cu1&cu-a slightly reclivous.

Second tergite about as long as broad anteriorly. Ovipositor very slender, strongly upcurved in apical half ( Fig. 103 View Figure ); sheath about as long as hind tibia.

Body brownish black to black. Clypeus, palpi, mandible (teeth blackish) and tegula yellow to brownish yellow. Pterostigma pale brown. Legs yellow, hind coxa dark brown to brownish black; hind tibia and all tarsi sometimes infuscate.

Male. Unknown.

Etymology. Named from the Latin minutus (small, minute) after its small size.
