Additional material examined: 1 ♀ India : Kerala , Kozhikode district, Kakkavayal ( 11°38’28.5”N & 76°07’52.9”E , 856 m ), 03.xi.2018 , Coll. S. Anagha [ ZSIK ], Regd. No. ZSI/ WGRC /IR/INV.14858 . Diagnosis. This species is clearly identifiable with antennal flagellum crenulate in profile with angular swelling ventrally ( Fig. 18 ); LID 0.8× UID; frons without interantennal tubercle ( Fig. 17 ); head and body black with bright yellow markings ( Fig. 13 ); shallowly punctured sculpturing on head and mesosoma; pronotum short, anterior margin almost straight, lateral corner sub-angulate, angulation variable; mesoscutum with notaular groove shallowly impressed anteriorly; parapsidal sulcus appearing as a fine, raised line; discs of scutellum and metanotum strongly raised; SMC2 almost rectangular, receiving crossvein lm-cu at basal half; SMC3 narrowed on vein Rs ( Fig. 21 ); propodeum short, barely convex in profile; metasoma much slender than mesosoma; Gt 1 gradually narrowed and petiolate or parallel-sided basally ( Fig. 22 ). Distribution . Oriental ( India : Kerala , Tamil Nadu , Uttarakhand . Elsewhere: Brunei , Indonesia , Malaysia , the Philippines , and Sri Lanka ); Palearctic ( Japan ) ( Shimizu & Wahis 2007 ). Variation. The additional specimen examined here shows darker body with pale brownish yellow spots on mesosoma compared to the bright yellow spots and patches of the holotype .
