Gauldiana nigra Khalaim & Ward , sp. nov.

( Figs 19 View FIGURES 16–20 , 34 View FIGURES 32–37 )

Comparison. The new species is similar to G. arantia as both have predominantly orange mesosoma, but differs from this species by the head predominantly black ( Fig. 34 View FIGURES 32–37 ), flagellum filiform and with 19 flagellomeres, and ovipositor shorter.

Description. Female. Body length 3.1 mm. Fore wing length 2.45 mm.

Head in dorsal view with gena almost 0.6× as long as eye width. Flagellum filiform, with 19 flagellomeres. Malar space 0.8× as long as basal mandibular width.

Propodeum with transverse carina vestigial, discernible only medially; basal part slightly shorter than apical area. Propodeal spiracle adjacent to pleural carina.

Fore wing ( Fig. 19 View FIGURES 16–20 ) with vein R1 almost reaching apex of the wing. Vein 2m-cu slightly postfurcal. Postnervulus intercepted near its middle. Hind wing with vein cu1&cu-a strongly reclivous.

Ovipositor weakly upcurved, somewhat stronger upcurved at apex; sheath 1.3× as long as hind tibia.

Head dark reddish brown, malar space and face orangish. Clypeus, palpi, mandible (teeth blackish), tegula and legs yellow. Antenna yellowish basally, gradually darkening towards apex, brown apically. Mesosoma and metasoma orange. Pterostigma pale brown.

Male. Flagellum with 20 flagellomeres, weakly narrowed towards apex. Head, metapleuron, propodeum and metasoma blackish.

Etymology. Named on account of its predominantly dark body colouration.
