sp. n.

Andesipolis bicolor Shimbori & Gessner  sp. n.

( Figs 21View FIGURES 14 – 25, 30View FIGURES 26 – 34, 68–73View FIGURES 68 – 73).

Female. Body length 3.7 mm; fore wing length 3.8 mm

Head. Smooth and polished, with scattered setae; 1.17x wider than mesoscutum. Face 1.66x broader than long, smooth and polished. Clypeus 2.66x broader than long. Malar space 0.42x eye height in frontal view. In lateral view, eyes as long as temple. Maximum width of lateral ocellus 0.43x ocell-ocular distance. Antenna about 1.1x longer than fore wing, 35 segmented; first flagellomere 2.8x longer than wide.

Mesosoma  . 1.8x longer than high. Mesonotum 1.39x longer than width of mesoscutum. Pronotum dorsally crenulate (mostly covered by head and mesoscutum); laterally smooth with pronotal groove crenulate anteriorly, scattered setae along posterior margin and ventrally. Mesonotum smooth and polished; mesoscutum protruding anteriorly over pronotum, with scattered setae medially and anteriorly; scutellar sulcus bare; scutellum with scattered setae mostly at posterior apex; notauli deeply impressed and crenulate dorsally, 0.32x the length of mesoscutum; mid pit 0.53x the length of mesoscutum; scutellum 0.72x longer than wide, smooth and polished; scutellar sulcus 0.26x longer than wide, crenulate; mesoscutellar trough costate proximally and rugose distally. Metanotum with distinct median carina; costate laterally. Mesopleuron mostly bare, with few scattered setae concentrated on anterior corner and ventrally; sternaulus crenulate; anterior corner of mesopleuron smooth. Epicnemial carina present ventrally, incomplete. Metapleuron smooth, mostly bare, with long and scattered setae ventrally. Propodeum smooth and polished, some rugosity inside areola anteriorly; median carina short, bifurcated basally; areola triangular, anteriorly roughly defined, with distinct cross-bridge and one pair of transverse lateral carinae ( Fig. 21View FIGURES 14 – 25), anterior pair absent. Hind coxa 1.55x longer than wide, slightly longer than metasomal TI. Hind basitarsus about 0.4x as long as hind tibia. Hind tarsal claws without basal lobe.

Wings. Fore wing. Stigma 4.3x longer than broad; vein r arising from middle of stigma. Vein r 0.4x longer than vein 3RSa. Vein 2RS straight, about 0.6x longer than 3RSa. Vein 3 RSa 0.77 x 3 RSb and 2.4x as long as vein r-m. Vein 1 Cub about 2.2x vein 1CUa. Vein (RS+M)b short and not pigmented. Vein 1-1AC 0.18x longer than vein 2- 1 A. Hind wing. Vein M +CU 2.67x longer than 1M. Vein cu-a 0.91x as long as 1M. Vein r-m 0.94x as long as 1M. 

Metasoma. TI 0.8x as long as apical width; smooth and polished with lateral apical areas costate; dorsal carinae short, converging but not meeting; dorsope deep and large. Metasoma beyond petiole apparently evenly sclerotized; TII about 1.66x longer than TIII. Ovipositor large, 1.1x longer than hind tibia; ovipositor sheaths 0.59x longer than ovipositor.

Color. Head orange-yellow, stemmaticum and occiput dorsally blackish. Mandibles light yellow, tips brown.

Palpi whitish. Antenna dark brown to black. Mesosoma  black, with orange-brown markings on mesoscutum midposteriorly and anteriorly at border with pronotum, mesopleuron near tegula, scutellar sulcus, scutellum and metanotum medially. Propodeum and metapleuron brown. Propodeum with yellowish markings posteriorly. Metasoma and legs pale light yellow. Hind leg apically from apical ¼ of tibia dark brown. Ovipositor red-brown, sheaths dark brown. Wings infuscate.

Male. Unknown.

Biology. Unknown

Comments. Differing notably from all other species, A. bicolor  sp. n. has infuscate wings with a very long second submarginal cell; the petiole is mostly smooth and polished but costate latero-apically (while in all other species the median region has some sculpturing and the latero-apical areas are smooth); the propodeum has a triangular areola covering most of its length, and the anterior pair of transverse lateral carinae is absent. The large and red-brown ovipositor is also a diagnostic character distinct from all other known species.

Distribution. Known only from type-locality at Itatiaia  National Park, Rio de Janeiro, Brazil, at 2,206 m of elevation.

Etymology. The species name is a reference for the striking contrasting colors of mesosoma  and metasoma.
