Mesosoma, lateral view; 49. Propodeum, dorsal view; 50. Metasoma, dorsal view; 51. Fore wing; 52. Hind wing. Diagnosis. Spilomena tuberculata sp. nov. differs from its congeners by the following combination of characters: mesosoma brownish yellow with few black patches; relative length to breadth of scape = 23:6; relative length to breadth of stigma = 56:17; propodeal dorsum rugose, postereo-lateral surface with transverse ridges, posteriorly with median longitudinal carina. Description. Holotype ♀ . Body length 5.6 mm ; fore wing length 3.6 mm . Colour. Head black; mandible (except apical tip brown), clypeus, antenna, pronotal lobe, tegula and legs pale yellow; mesoscutum, scutellum, metanotum and metasoma yellowish brown; propodeum brown with yellow patches laterally; mesopleuron yellow; metapleuron brown; fore wing veins and stigma light brown. Vestiture. Scattered sparse setae on clypeus and mandible; T3–T6 each with scattered setae; ventral margin of T6 with apical suberect setae; remaining body with sparse vestiture. Head . Clypeus shiny, with scattered setae, markedly convex ( Fig. 46 ); interantennal tubercle prominent, acutely pointed and extending into median carina up to mid frons; mandible bidentate apically, inner mandibular tooth short and blunt; relative length to breadth of scape = 23:6; frons and vertex reticulate with dense setigerous micropunctures; inner eye margin straight; gena imbricate, impunctate. Mesosoma . Pronotum dull, with longitudinal rugae; anterior carina of pronotal collar conspicuous and straight; mesoscutum reticulate with dense micropunctures; admedian line and parapsidal line lacking; scutellum reticulate with dense micropunctures, anterior groove of scutellum not broadened by crenulation; metanotum reticulate, longitudinally rugose laterally; mesopleuron reticulate with scattered setigerous punctures posteriorly ( Fig. 48 ); metapleuron with irregular ridges; stigma elongate, relative length to breadth = 56:17; recurrent vein of fore wing received well within first submarginal cell; propodeal dorsum rugose ( Fig. 49 ), lateral surface finely aciculate, with scattered transverse ridges, posterior surface with irregular transverse ridges and longitudinal carina medially. Metasoma . T1 and T2 shiny, impunctate; T3–T6 with scattered setigerous punctures on entire surface; T6 apically with dense brush of short setae. Male. Unknown. Etymology. The species name is derived from a distinctively conspicuous interantennal tubercle. Distribution. India ( Karnataka ).
