Holotype. Female; body length = 0.70 (0.65–0.82) mm; n = 5

Colour ( Figure 10 View Figure 10 (a)). Head, mesonotum and metasoma blackish brown; hyperoccipital carina black; mesoscutum with a weak yellowish brown line posteriorly; mesoscutellum with a black band followed by yellowish brown line posteriorly; antenna dark brown except brown A3–A6; legs dark brown to black.

Head ( Figure 10 View Figure 10 (a–e)). Head 1.14 (1.11–1.21)× as wide as high; IOS wide, 0.68 (0.65–- 0.69)× width of head and 1.59 (1.56–1.65)× eye length; eye small (L: W = 9.8:7.8) setose, not touching hyperoccipital carina posteriorly; head height 2.36 (2.34–2.42)× eye length; POL>LOL in ratio of 14.4:8.7; lateral ocellus away from orbits by 0.45 (0.43–0.49)× MOD; distance from posterior margin of lateral ocellus to hyperoccipital carina 0.91 (0.89–0.94)× MOD; pilosity of moderate density, setae of medium length, shorter than those on mesonotum and metasoma; interantennal process triangular, reticulate; central keel absent, instead several longitudinal striae present along imaginary central keel; facial striae long, extending 0.63 (0.60–0.71)× the length from mandibular end to lower orbit; malar striae absent; lower frons adjacent to imaginary central keel with longitudinal striae followed by reticulations, with scutes longer than wide; upper frons and vertex smooth, setose; gena postero-dorsally weakly reticulate, remainder smooth, 3.08 (3.02–3.11)× as long as wide; anterior margin of gena in contact with 0.53 (0.50–0.56)× length of ventral margin of eye; length of A1 0.94 (0.91–0.97)× that of clava; length of A2 0.42 (0.38–0.44)× that of A1.

Mesosoma ( Figure 10 View Figure 10 (a,c,e)). Mesoscutum and mesoscutellum 0.43 (0.40–0.51)× and 0.17 (0.15–0.18)× as long as wide, respectively; mesoscutum and mesoscutellum imbricate; metascutellum not visible; propodeum smooth dorsally, 0.62 (0.60–0.65)× length of mesoscutellum medially; pilosity of moderate density, setae of medium length; lateral pronotal area antero-dorsally imbricate, antero-medially weakly vertically striate, posteroventrally with transverse carinae, remainder smooth; postero-dorsal margin of lateral pronotal area with two short, weak projections; ventral margin of lateral pronotal area extending as a short blunt projection; transverse carinae on dorsal mesopleuron terminate above the level of dorsal metapleuron; mesopleuron ventrally weakly imbricate-reticulate followed by a semicircular and an oblique carinae, remainder smooth; mesopleuron with a short projection ventrally; mesopleural pit large and round; metapleuron smooth; posterior suture of metapleuron almost straight but gently curving dorsally to meet posterior mesopleuron; dorsal level of posterior metapleural suture ventral to level of antero-lateral margin of T 2; sculpturing of propodeum anterior to spiracle with short carinae; region posterior to spiracle with a short carina on dorsal and ventral end of spiracle; region ventral to spiracle with four long and two short transverse carinae; remainder of lateral propodeum smooth; propodeal spiracular opening tear-drop shaped.

Metasoma ( Figure 10 View Figure 10 (a,c,e)). Length and width of metasoma subequal; pilosity dense, setae of medium length; T 2 anteriorly finely imbricate, posteriorly smooth; remaining tergites smooth.

Material examined. Holotype: Female ( ICAR / NBAIR / P2969 ), INDIA: Himachal Pradesh: Shimla , NBPGR, 31 ° 05 ʹ 55 ʹ ’ N 77 ° 09 ʹ 34 ʹ ’E, 1911 m, YPT, 08.IX.2015 ; Paratypes: 13 females ( ICAR / NBAIR / P2970–2982 ), same as holotype; 4 females ( ICAR / NBAIR / P2983–2986 ), same as holotype, 02 .VIII .2014; 5 females ( ICAR / NBAIR / P3059 P3063 ), same as holotype, 02 . VIII .2014; 1 female ( ICAR / NBAIR / P3064 ), same as holotype, 08 .IX .2015; 3 females ( ICAR / NBAIR / P3405 P3407 ), Jammu and Kashmir: Srinagar: Sher –e– Kashmir University of Agricultural Sciences and Technology (SKAUST), Shalimar Campus, 34 ° 08 ʹ 52 ʹ ’ N 74 ° 52 ʹ 39 ʹ ’E, 1597 m, SN, 01 . VI.2010.

Etymology. The epithet ‘densipilosus’ refers to the dense setae on metasoma. The name is treated as an adjective.

Diagnosis. B. densipilosus sp. n. is closer to B. menaka sp. n. but differs from it in having a smooth clypeus, and posterior suture of metapleuron curves dorsally to meet posterior mesopleural suture. Whereas B. menaka has a transversely carinate clypeus and the posterior suture of metapleuron does not curve dorsally towards mesopleuron.
