Bolivar brasiliensis Nunes sp. nov.

Figs 1 A–F.

Diagnosis. Bolivar brasiliensis sp. nov. is morphologically similar to B. risaraldensis. These two species are distinguished from the remaining members of Bolivar by having a poorly defined propodeal areola, only slightly distinct basally, and propodeum strongly areolate-rugose on apical third. However, the new species can be distinguished from B. risaraldensis by having a body mostly brown to dark brown (with a yellow-dark brown colour pattern in B. risaraldensis), precoxal sulcus running along basal 0.8–0.9 of mesopleuron (about 0.7 in B. risaraldensis), and males usually with an evident protruding lateral area above the pronotal groove.

Description. Female. Body length: 4.5 mm. Colour: head brown to dark brown; face and area surrounding eyes light brown; scape and pedicel brown, with a lateral dark brown stripe. Flagellomeres light brown at the base, turning dark brown to apex, preapical eight (right flagellum), nine (left flagellum) flagellomeres white, apical two brown. Pronotum brown dorsolaterally, light brown to yellow ventrally; propleuron light brown to yellow; mesoscutum, propodeum and first metasomal tergite black; mesopleuron black to dark brown dorsally, light brown ventrally; venter of mesosoma light brown to yellow. Wings slightly dusky; veins and stigma brown; tegula light yellow. Legs light brown to yellow. Fore and middle coxae white, hind coxa dorsally yellow to brown, middle and hind femora brown. Third to fifth metasomal tergites brown, second and sixth light brown, remainder dark brown. Ovipositor brown, strongly sclerotized at apex; ovipositor sheaths light brown.

Head: vertex and frons finely striate with granulate microscultpure; face slightly transversally striate; temple and gena smooth; clypeus smooth to slightly granulate. Eye 1.2 × higher than wide. Malar space height/eye height ratio 0.4. Temple/eye length ratio (dorsal view) 0.25. Distance between eye and ocellus 2.2 × diameter of lateral ocellus. Flagellum 29-segmented.

Mesosoma: pronotum smooth, slightly coriaceous laterally. Pronotal groove wide, deep and slightly scrobiculate, smooth posteriorly. Propleuron slightly striated anteriorly, slightly coriaceous posteriorly. Mesoscutal lobes coriaceous. Notauli deep, scrobiculate anteriorly, not joining, reaching base of scutellum in a sub-parallel line. Scutellar disc slightly coriaceous. Scutellar sulcus with three longitudinal carinae. Subalar sulcus wide, shallow, scrobiculate dorsally, smooth medially and ventrally. Mesopleural sulcus shallow and scrobiculate, joining scutellar sulcus. Mesopleuron smooth to coriaceous dorsally, coriaceous medially and ventrally. Precoxal sulcus shallow, striated, running along basal 0.8 of mesopleuron. Venter of mesosoma coriaceous. Metapleuron coriaceous to coriaceous-rugose distally. Propodeum coriaceous within the two lateral longitudinal carinae, areolate-rugose with coriaceous microsculpture posteriorly and laterally. Propodeal areola not defined, only slightly distinct basally. Length of propodeal areola about 0.5 × maximum length of propodeum.

Wings: fore wing length 3.1 mm, length/width ratio 3.5; vein m-cu interstitial to vein 2RS; vein cu-a interstitial to vein 1M; veins 2RS/2M ratio 0.6. Hind wing vein 1cu-a interstitial to vein 1M; vein M + CU 0.4 × length of vein 1M.

Legs: fore tibia with a row of various spines. Mid tibia with a row of at least five spines; hind femur and coxa finely coriaceous. Hind femur length 4.0 × its maximum width.

Metasoma: length of first tergite 2.0 × its maximum apical width, coriaceous basally, longitudinally costate with coriaceous microsculpture at apex. Basal sternal plate/length of first tergum 0.6. Second tergite entirely striate.

Suture between second and third median tergites distinct and straight. Remaining tergites smooth and polished. Ovipositor 0.8 × length of metasoma.

Variation. Body length 3.5–6.0 mm. Mesopleuron dark brown to black, light brown to yellow ventrally; first metasomal tergite dark brown to black, second one light brown to yellow; legs light brown to yellow; hind coxa light brown to brown apically. Temple/eye length ratio in dorsal view 0.2–0.28. Flagellomeres 23–31-segmented; with 6–10 preapical white and 1–2 apical dark flagellomeres. Postero-median area between notauli with or without various longitudinal carinae. Scutellar disc slightly granulate to smooth. Precoxal sulcus running along basal 0.8–0.9 of mesopleuron. Hind femur length 4.0–4.5 its maximum width. First metasomal tergite 1.75–2.0 its maximum width. Basal sternal plate 0.55–0.65 × length of first metasomal median tergite. Ovipositor length 0.8–1.1 mm.

Male. Similar to female. Usually (> 80% of specimens) with a distinct, smooth to slightly coriaceous protruding lateral area above pronotal groove. Lateral protruding area of pronotum yellow to light brown. Precoxal sulcus running along basal 0.9 of mesopleuron. First tergite 2.3 × the apical width; second tergite width 0.7 × its length.

Distribution. Bolivar brasiliensis sp. nov. occurs along the Atlantic coastal region in Brazil, from the states of Pernambuco to Santa Catarina ( Fig. 2 ). Most of the specimens were collected in Atlantic rain forest (“ Mata Atlantica”).

Biology. Unknown.

Etymology. This species refers to the country where the new species occurs, Brazil.
