Head 1.14× as wide as high; IOS wide, 0.54× width of head and 1.22× eye length; eye small (L: W = 10.2:9.6) setose, posterior orbital carina extending up to hyperoccipital carina, eye not touching hyperoccipital carina posteriorly; head height 2.13× eye length; POL>LOL in ratio of 13.8:8.6; lateral ocellus contiguous with orbits; distance between posterior margin of lateral ocellus and hyperoccipital carina 1.32× MOD; pilosity of moderate density, setae of medium length, shorter than those on mesonotum and metasoma; interantennal process triangular, rugose; length of central keel 0.39× distance from interantennal process to median ocellus; facial striae long, extending up to lower orbit; malar striae sparse; frons adjacent to central keel finely reticulate, followed by semicircular striae and reticulations, with scutes longer than wide; upper frons and vertex finely imbricate; gena smooth, 3.21× as long as wide; anterior margin of gena in contact with 0.51× length of ventral margin of eye; length of A1 0.92× that of clava; length of A2 0.38× that of A1.

Mesosoma ( Figure 31 View Figure 31 (a,c,e)). Mesoscutum and mesoscutellum 0.52× and 0.21× as long as wide, respectively; mesoscutum and mesoscutellum finely imbricate with smooth posterior margin; metascutellum not visible; propodeum smooth dorsally, 0.61× length of mesoscutellum medially; pilosity of moderate density, setae of medium length; lateral pronotal area dorsally imbricate with vertical striations posteriorly, antero-medially weakly vertically striate-reticulate, remainder with weak impressions of reticulations; postero-dorsal margin of lateral pronotal area with two short projections; ventral margin of lateral pronotal area extending as a short blunt projection; transverse carinae on dorsal mesopleuron terminate above the dorsal level of metapleuron; mesopleuron ventrally imbricate up to mesopleural pit dorsally, followed by oblique carinae ventrally, remainder smooth with sparse transverse costae; mesopleuron not projecting ventrally; mesopleural pit small; metapleuron ventrally shallowly foveate, remainder with weak impressions of foveae; posterior suture of metapleuron straight, gently curving dorsally towards posterior mesopleuron; dorsal level of posterior metapleural suture ventral to level of antero-lateral margin of T 2; sculpturing of propodeum anterior to spiracle carinate; region posterior to spiracle smooth with one short and two long transverse carinae; region ventral to spiracle with three transverse, one vertical and several oblique carinae; remainder of lateral propodeum with impressions of weak foveae; propodeal spiracular opening tear-drop shaped.

Metasoma ( Figure 31 View Figure 31 (a,c,e)). Metasoma as 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 / P3088 ), INDIA: Himachal Pradesh: Naggar , 32 ° 06 ʹ 50 ʹ ’ N 77 ° 09 ʹ 51 ʹ ’E, 1714 m, MT, 07.VII.2013.

Etymology. This species is named after Takshaka, the king of the Nagas or snakes in Hindu mythology. The name is treated as a noun in apposition.

Diagnosis. This species is closer to B. ravana sp. n. and the diagnosis is mentioned under the latter.
