(Figs. 3A–D)
Diagnosis. This species differ from B. licina and B. contophleba, mainly by having most of the mesosoma rugose. However it can also be distinguished by the size of the fore wing vein r, which is 0.30 length of 3RSa vein (about 0.6 of 3RSa in B. licina and equal to 3RSa in B. contophleba), and by the ovipositor length (Fig. 3A) which is equal to metasoma (smaller than the metasoma in the other two species). B. longicaudus n. sp. could be misidentified as a Doryctinus species, however, the hind wing vein M+CU length is 0.5 of 1M (less than 0.5 in Doryctinus), the first metasomal tergum length is equal to its apical width (Fig. 3D) (length twice or more than the apical width in Doryctinus), terga 4–8 are smooth (Fig. 3D) (sculptured in Doryctinus), and the mesoscutum is small and rugose (Fig. 3B) (mesoscutum long and costate in Doryctinus).
Description. Female (Fig. 3A). Body length: 31 mm. Body color: area around the eyes and upper face region brown, remaining head dark brown; scape and pedicel yellow; first antennal flagellomeres light brown, the remaining darkening until dark brown to the apex; labial and maxillary palps yellow; mesosoma dark brown, with pronotum and mesonotum brown; wings hyaline; veins brown; stigma brown with white basal region; tegula brown; fore and middle legs with coxa brown, trochanter and trochantellus yellow, femur, tibia and tarsus brown, with last tarsomere dark brown; coxa of hind leg dark brown, trochanter and trochantellus yellow, femur and tibia brown, tarsus light brown with the last tarsomere dark brown; first and second metasomal terga dark brown; basal half of terga 3–5 dark brown, apical half brown; tergum 6 brown; terga 7 and 8 yellow; ovipositor sheaths dark brown; ovipositor brown with black apex.
Head: several white long setae present throughout the head; clypeus, face, frons and vertex finely striaterugose; temple slightly rugose near the occipital carina, remaining temple smooth; gena smooth; occipital carina present, meeting the hypostomal carina; oral cavity rounded, length equal the malar space; ocell-ocular distance 2.5 times the diameter of lateral ocellus; antenna with 19 flagellomeres.
Mesosoma: white long setae throughout the mesosoma; pronotum slightly rugose in dorsal view, pronotal groove thin and scrobiculate, lateral area of pronotum rugose; propleuron finely rugose; mesoscutum declivous anteriorly; mesonotal lobes rugose and hard to define (Fig. 3B); notaulus thin and scrobiculate, present only in the anterior region of mesoscutum; scutellar disk rugose; mesopleuron rugose (Fig. 3C); subalar sulcus scrobiculate, enclosing a rugose triangular area at the anterodorsal region of mesopleuron; mesopleural sulcus thin and scrobiculate; precoxal sulcus scrobiculate and absent in the posterior region of mesopleuron (Fig. 3C); venter of mesosoma striate-rugose; propodeum rugose anteriorly and rugose-areolate posteriorly; lateral and basal carinae absent; basal median areas and areola of propodeum absents; metapleuron anterodorsal region finely rugose becoming rugose-areolate toward the posteroventral region.
Wings: fore wing vein r 0.30 length of 3RSa vein; 2RS and r-m present; 1cu-a distal to 1M; first subdiscal cell open at apex, 2cu-a absent; hind wing M+CU 0.5 length of 1M.
Legs: left fore tibia with a row of seven spines, right fore tibia with a row of five spines; medium tibia with a row of six spines; legs smooth, except for the femur slightly coriaceous, hind coxa rugose with basal tubercle distinct.
Metasoma: first metasomal tergum costate-rugose, length equal its apical width (Fig. 3D); dorsope present; basal sternal plate 0.15 length of first tergum; second metasomal tergum striate-rugose; groove between the second and third tergum very weak and straight; third tergum striate-rugose in basal half, remaining tergum smooth and shiny; fourth tergum smooth and shiny, with a transversal striate line in the middle (Fig. 3D); remaining terga smooth and shiny; ovipositor length equal to metasoma (Fig. 3A).
Male: Unknown.
Distribution. Brazil (State of Roraima)
Etymology. The specific name comes from the Latin longus and the Latin cauda in reference to the long ovipositor of this species.
