Eosmicromyrmilla subbuka Terine, Lelej & Girish Kumar , sp. nov.

( Figs 3–11 , 21–23 )

Diagnosis. MALE. Clypeus convex, punctate, without preapical groove. Pronotum anterodorsally transversely striate, posterodorsally sparsely punctate. Metapleuron dorsally transversely striate, mid and ventral part smooth. Lateral propodeal face reticulate with smooth portion adjacent to metapleuron. S6 strongly concave posteriorly with median narrow emargination almost half the length of visible (punctured) part of S6. S7 hidden. Apical part of paramere almost two times longer than paramere base (lateral view), compressed bilaterally, downcurved and pointed apically; paramere outside basally with long dense whitish setae. Penis valve without tooth preapically. FEMALE. Unknown.

Description. MALE. Body length 5.55–7.40 mm (holotype 7.04 mm). Coloration and setation. Body black. Ocellar triangle with sparse subappressed white and black setae. Mandible black, preapically brownish. Clypeus with long dense, recumbent white setae. Legs black, mid and hind tibial spurs white, fore tibial spurs brownish. Mandible, frons, vertex and genae with scattered recumbent white setae mixed with few erect black setae. Mesosoma with sparse, recumbent and erect white setae, denser on mesopleuron, mixed with sparse erect black setae on pronotum, mesoscutum and mesoscutellum; mesopleuron with dense white setae above mid coxa. Legs with recumbent and erect white setae. Metasomal segments 1–4 with scattered long, erect whitish setae, T2 disc and T5–7 with sparse long black setae. T1–4 and S2–5 with white apical fringe. S6 and S8 with black setae mixed with few white setae.

Head. Almost oval (frontal view), not elongated behind eyes, head width 1.16 × maximum pronotal width. Ocelli small, POL 0.55 × OOL. Mandible tridentate, without sub-basal inner tubercle. Ratio of pedicel and F1-3 length 1.0:1.3:2.7:2.7. Clypeus convex, punctate, without preapical groove.

Mesosoma . Pronotum anterodorsally transversely striate, posterodorsally sparsely punctate, laterally mostly rugulose, pronotal carina strongly developed anteriorly. Mesoscutum sparsely punctate, with parapsidal furrows, notauli lacking. Mesoscutellum produced and overhanging metanotum, posterior margin slightly emarginated, mesoscutellum reticulate, reticulae smaller than on posterior propodeal face. Mesopleuron rugose to reticulate, tegula with smooth disc and few punctures marginally. Metapleuron in dorsal half transversely rugose, mid and ventral part smooth. Propodeal lateral face reticulate with smooth part adjacent to metapleuron. Dorsal and posterior propodeal faces reticulate, reticulae size larger towards metapostnotum, posterior and lateral propodeal faces separated by wavy carina.

Wings. Forewing evenly setose, hyaline except brownish apical third, veins brown, veins distal of cells nebulose; two submarginal cells, second submarginal cell petiolate with marginal cell and smaller than marginal cell, marginal cell with four abscissae.

Metasoma. T1 maximum width 0.75 × T2 maximum width, T1 length 0.5 × T2 length, T1 not constricted posteriorly. T2 with short lateral felt line, S2 with long lateral felt lines. S6 strongly concave posteriorly with median narrow emargination almost half the length of visible (punctured) part of S6. S7 hidden, not visible. S8 (hypopygium) with median longitudinal narrow emargination which carinated laterally and narrowed basally, with notch on half of carina, and oblique carina from notch to latero-basal corner of S8, densely punctate laterad of emargination.

Genitalia. Apical part of paramere almost two times longer than paramere base (lateral view), compressed bilaterally, downcurved and pointed apically; paramere outside basally with long dense whitish setae, apically with sparse whitish setae. Penis valve lamellate, apically rounded, without preapical tooth. Volsella lamellate, ventrally and apically with long yellowish setae.

Paratypes. Similar to the holotype except one paratype from Karnataka has the mesopleuron with dense setae obscuring the reticulations. Body length: 5.55 mm.

FEMALE. Unknown.
