Type material. Holotype ♀, mounted on triangular card, India: Uttar Pradesh, Lalitpur district, Babina (25°16’957”N & 78°30’379”E, 303 m), Coll. P. Girish Kumar, ( ZSIK) Regd. No. ZSI/ WGRC /IR/INV.13596.

Diagnosis. Frons with fine and transverse rugae; vertex with irregular rugulae; pronotum slender, anteriorly with weak transverse striae, posteriorly coriaceous to finely reticulate; scutellum microreticulate; propleuron and mesopleuron coriaceous; propodeum anteriorly microreticulate to alutaceous, postero-laterally longitudinal areola and coriaceous interspaces, inside of areola imbricate; 2-CU 1 of fore wing absent. This species runs close to F. sudhae in having the hind femora ventrally with two large teeth. However, the new species differs from F. sudhae as follows: vertex with two carinae (in F. sudhae vertex with four carinae); mesoscutum with a median longitudinal grove (in F. sudhae mesoscutum without such grove). The species also comes close to F. idukkiensis , F. chinnarensis and F. frontilinea in having vertex with two carinae, but differs as follows: stemmaticum without a distinct medial grove (a distinct medial grove present in F. idukkiensis ); ovipositor sheath longer than metasoma (ovipositor sheath shorter than metasoma in F. chinnarensis ); first metasomal tergite shorter than combined remaining segments (in F. frontilinea first tergite longer than combined remaining segments). The new species runs to the Oriental species F. maculiferus Hong et al. ( Hong et al. 2011) in having third metasomal tergite with two large ivory patches, propodeum almost matt on anterior 2/3 rd and foveate on the rest. However, the new species differs from F. maculiferus in having: face with yellow patch reaching second set of tubercles (in F. maculiferus the patch not extending beyond anterior coronal teeth); vertex with two carinae (in F. maculiferus vertex with three carinae); scutellum black, flat medially and almost in same line with mesoscutum and propodeum (in F. maculiferus scutellum reddish brown, medially distinctly convex); hind femora, reddish brown and densely reticulate throughout the lamina (in F. maculiferus hind femora orange red, reticulate dorsally with punctate lamina ventrally); ovipositor sheath completely brownish black (in F. maculiferus ovipositor sheath with a brownish subapical band).

Description. Holotype. ♀. Body length 6.1 mm; ovipositor length 4.43 mm; fore wing length 3.54 mm.

Colour. Brownish black with the following parts as follows: frons till the anterior coronal teeth and lateral halfway along the outer margin of eyes yellow; temples brown; mandibles yellow with apex black; ovipositor sheath black.

Head. Antenna with 22 distinct antennomeres; first flagellomere 3.9× as long as wide, and 0.7× as long as second flagellomere; three anterior coronal teeth large and acute, both posterior ones short and wider; frons finely and transversely rugate; coronal area with weak longitudinal carinae; vertex finely and transversely striate, two carinae and without a shallow median longitudinal furrow ( Fig. 35 ); temple non-angulate, smooth and shiny ( Fig. 34 ).

Mesosoma . Pronotum slender and mostly coriaceous to faintly pitted, without transverse rugulae anteriorly; weakly carinate dorso-medially and laterally; neck anteriorly deeply emarginated, neck at slightly lower level than middle part of pronotum; anterior half of mesoscutum finely rugose to coriaceous with irregular areola, posterior half with a median carina ( Fig. 36 ); scutellum, propleuron and mesopleuron coriaceous to micropitted ( Fig. 38 ); scutellum separated from axilla by means of a large furrow, not differentiated in the form of fovea with scattered small setae; axillae separated from each other by a large alveola; propodeum with medium-sized, circular areola with wide coriaceous interspaces, inside of foveae imbricate to alutaceous; fore wing with 2-CU1 absent; pterostigma elongate and subparallel-sided, turning acute apically; vein r and vein SR1 obtusely-angled, vein r ends 0.2× length of pterostigma behind level of apex of pterostigma; vein SR1 subparallel to costal margin ( Fig. 37 ); hind coxa weakly striate, ventrally with moderate striae ( Fig. 39 ); hind femur microreticulate, ventrally with two large acute teeth and with two smaller tubercle basally, three denticles in between the large teeth and a stub like lobe apically; hind tibia faintly coriaceous, as long as hind femur, basal narrow part of hind tibia 0.96× as long as widened part, inner side of widened part basally distinctly depressed, followed by convex and setose area, apically densely setose; hind tarsi densely setose ( Fig. 40 ).

Metasoma. First tergite rugose with faint transverse striae, weakly annulate, sparsely setose, 6.86× as long as its maximum width ( Fig. 39 ), 1.91× as long as second tergite and 0.7× as long as remainder of metasoma; post-petiolar tergites largely smooth to weakly coriaceous ( Fig. 42 ); pygidial area distinctly differentiated, pygidial impression moderate, reverse V-shaped ( Fig. 41 ); length of ovipositor sheath 0.72× as long as body length, without a subapical whitish band ( Fig. 43 ).

Male. Unknown.

Distribution. Oriental: India (Uttar Pradesh).

Host. Unknown.

Etymology. The species is named after Dr. P.M. Sureshan (Scientist-E & Officer-in-Charge, Western Ghat Regional Centre, Zoological Survey of India, Kozhikode) for his valuable contributions towards the study of Indian Stephanidae .
