( Figs 1–10 )

Type species. Ayaanella globugaster M.T. Khan & Anis sp. nov.

Description. Female. Head ( Fig. 1 ); antennal torulus placed slightly above lower margin of eye; malar space dark, as long as or shorter than eye width; ocelli arranged in obtuse triangle; mandible ( Fig. 2 ) 4-dentate, third tooth shorter, and a concavity between third and fourth teeth; maxillary palp ( Fig. 3 ) unsegmented, swollen basally, with one seta at apex. Antennal formula 1, 1, (2), 2, 3; antenna ( Figs 5–8 ) with 2 anelli ( Figs 7, 8 : A1 and A2); funicle 2 segmented, segments asymmetrical, with PLS, F2 broader than long; clava 3-segmented with very long setae and PLS. Mesosoma with pronotum medially divided into two plates; mid lobe of mesoscutum and scutellum each with 2 pairs (2+2) setae; side lobe of mesoscutum with 1 seta along anterolateral corner and axilla; propodeal margin almost straight posteriorly and about as long as metanotum medially; posterior two-thirds of mesoscutum, and scutellum with longitudinally cellulate sculpture, anterior one-third of mesoscutum with polygonal cells. Fore wing hyaline with venation extending to slightly less than half wing length; costal cell very narrow; marginal vein longer than premarginal or stigmal veins; premarginal vein broader than marginal vein; RS1 absent [except two or three setae below stigmal vein]; disc moderately densely setose with setae arranged in rows. Legs with tarsal formula 3-3-3. Metasoma longer than mesosoma; ovipositor short, extending from TV of gaster and hardly exserted.
