Colour ( Figure 33 View Figure 33 (a)). Head, mesonotum and metasoma dark brown, mesoscutellum and propodeum paler than remainder; posterior tergite yellow; hyperoccipital carina black; posterior margin of mesoscutum with a black band; posterior margin of mesoscutellum with a black band followed by a yellow line; antenna brownish yellow except dark brown A2; legs yellowish brown to dark brown.

Head ( Figure 33 View Figure 33 (a–e)). Head 1.15× as wide as high; IOS wide, 0.42× width of head and 0.9× eye length; eye (L: W = 15.6:13.1) densely setose, touching hyperoccipital carina posteriorly; head height 1.8× eye length; POL>LOL in ratio of 18.3:12.8; lateral ocellus contiguous with orbit; distance between posterior margin of lateral ocellus and hyperoccipital carina 0.8× MOD; pilosity of moderate density, setae of medium length, shorter than those on mesonotum and metasoma; interantennal process triangular, pointed, rugose; central keel long, 0.71× distance from interantennal process to median ocellus; facial striae very long extending up to lower orbit; orbital carina extending ventrally below the dorsal level of facial striae; malar striae sparse; frons adjacent to central keel smooth followed by sparse longitudinal reticulations; upper frons and vertex finely reticulate; gena dorsally finely reticulate, remainder with oblique striae, with sparse short costae on posterior margin, 4.2× as long as wide; anterior margin of gena in contact with 0.67× length of ventral margin of eye; length of A1 0.89× that of clava; length of A2 0.39× that of A1.

Mesosoma ( Figure 33 View Figure 33 (a,c,e)). Mesoscutum and mesoscutellum 0.55× and 0.21× as long as wide, respectively; mesoscutum and mesoscutellum finely imbricate, scutes smaller on mesoscutellum than mesoscutum; metascutellum not visible; propodeum smooth dorsally, 0.42× length of mesoscutellum medially; pilosity of moderate density, setae of medium length; lateral pronotal area dorsally imbricate, postero-dorsally striate, remain- der with weak impressions of reticulations except for smooth antero-ventral region; postero-dorsal margin of lateral pronotal area with two short projections; ventral margin of lateral pronotal area extending as a blunt projection; transverse carinae on dorsal mesopleuron terminate above the level of dorsal metapleuron, ventrally with an imbricate patch followed by semicircular and oblique carinae, remainder smooth; mesopleuron extending as a short, sharp projection ventrally; mesopleural pit short; metapleuron smooth except for weak impressions of foveae ventrally; posterior suture of metapleuron straight with a gentle curve basally and bending towards mesopleuron dorsally; dorsal level of posterior metapleural suture level with antero-lateral margin of T 2; sculpturing of propodeum anterior to spiracle smooth, with a fovea followed by four transverse carinae, which have small protuberances anteriorly with a seta; region posterior to spiracle with a carina on dorsal and ventral margins; region ventral to spiracle smooth with an oblique carina enclosing a seta; remainder of lateral propodeum smooth with a transverse carina antero-ventrally; propodeal spiracular opening round.

Metasoma ( Figure 33 View Figure 33 (a,c,e)). Metasoma 1.2× long as wide; pilosity of moderate density, setae of medium length; T 2 anteriorly finely imbricate, posteriorly smooth; remaining tergites smooth.

Material examined. Holotype: Female ( ICAR / NBAIR / P3089 ), INDIA: Karnataka: Mudigere, College of Horticulture , 13 ° 06 ʹ 54 ʹ ’ N 75 ° 37 ʹ 57 ʹ ’E, 976 m, YPT, 02.X.2015.

Etymology. This species is named after the divine seductress Tilottama, an Apsara or female spirit in Hindu mythology. The name is treated as a noun in apposition.

Diagnosis. This species is closer to B. giganteus sp. n. and diagnostic characters are mentioned under the latter.
