Holotype. Female; body length = 0.62 (0.60–0.67) mm; n = 5

Colour ( Figure 29 View Figure 29 (a)). Head, mesonotum and metasoma honey brown, propodeum pale; hyperoccipital carina black; mesoscutum and mesoscutellum with a black band on

posterior margins; A1 and A2 brown, remaining antennomeres yellowish brown; legs brownish yellow.

Head ( Figure 29 View Figure 29 (a–e)). Head 1.12 (1.05–1.16)× as wide as high; IOS 0.56 (0.51–0.58)× width of head, 1.41 (1.39–1.45)× eye length; eye small (L: W = 9.0:7.0), setose, not touching hyperoccipital carina posteriorly; head height 1.91 (1.81–2.0)× eye length; POL>LOL in ratio of 14.1:8.8; lateral ocellus away from orbit, OOL 0.82 (0.80–0.85)× MOD; distance between posterior margin of lateral ocellus and hyperoccipital carina 0.72 (0.70–0.75)× MOD; pilosity of moderate density, setae of medium length, shorter than those on mesonotum and metasoma; interantennal process triangular, weakly rugose; central keel not distinct, weakly represented with faint longitudinal striae; facial striae long, extending 0.66 (0.62–0.73)× the length from mandibular end to lower orbit; malar striae absent; frons and vertex smooth; gena smooth with weak reticulations dorsally and no costae on postero-ventral margin, 3.21 (3.12–3.25)× as long as wide; anterior margin of gena in contact with 0.51 (0.49–0.53)× length of ventral margin of eye; length of A1 subequal to that of clava; length of A2 0.43 (0.41–0.46)× that of A1.

Mesosoma ( Figure 29 View Figure 29 (a,c,e)). Mesoscutum and mesoscutellum 0.55 (0.51–0.61)× and 0.17 (0.15–0.18)× as long as wide, respectively; mesoscutum imbricate; mesoscutellum predominantly smooth; metascutellum not visible; propodeum smooth dorsally, 0.50 (0.41–0.52)× length of mesoscutellum medially; pilosity of moderate density, setae of medium length; lateral pronotal area dorsally imbricate, antero-medially with weak vertical striae, remainder smooth; 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 with a small reticulate patch ventrally, remainder smooth; mesopleuron extending as a short projection ventrally; mesopleural pit short; metapleuron smooth, except for sparse uneven carinae ventrally; anterior mesopleural suture not distinct as a result of which lateral pronotal area and mesopleuron seem to merge; posterior suture of metapleuron almost straight not curving dorsally towards mesopleuron; dorsal level of posterior metapleural suture ventral to level of antero-lateral margin of T 2; sculpturing of propodeum anterior to spiracle smooth, posterior to spiracle with a short carina and a seta on dorsal and ventral margin; region ventral to spiracle with two oblique carinae with a seta on each; remainder of lateral propodeum smooth; propodeal spiracular opening round.

Metasoma ( Figure 29 View Figure 29 (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.

Etymology. This species is named after our entomologist friend and colleague Dr. K. Sreedevi. The name is treated as a noun in the genitive case.

Diagnosis. B. sreedeviae sp. n. is closer to B. menaka sp. n. and B. densipilosus sp. n. but differs from them in having a smooth A1 and mesoscutellum whereas B. menaka sp. n. and B. densipilosus sp. n. have sculptured A1 and mesoscutellum.
