Andesipolis shawi Shimbori & Gessner sp. n.

( Figs 50 , 145–148 )

Female. Body length 2.3–2.9 mm; fore wing length 2.5–2.9 mm.

Head. Smooth and polished, with scattered setae; 1.19–1.28x wider than mesoscutum. Face 1.7–1.8x broader than long, smooth and polished. Clypeus 2.2–2.3x broader than long. Malar space about 0.41–0.45x eye height in frontal view. In lateral view, eyes 1.5–1.9x longer than temple. Maximum width of lateral ocellus 0.42–0.46x ocellocular distance. Antenna about 1.1x longer than fore wing, 28 segmented; first flagellomere 3.6–4.0x longer than wide.

Mesosoma . About 1.57–1.79x longer than high. Mesonotum 1.14–1.17x longer than width of mesoscutum. Pronotum dorsally with smooth region between narrow crenulate anterior sulcus and posterior region; with distinct mid-longitudinal carina anteriorly; 0.88x longer than vertex, the posterior region about as long as anterior region; laterally smooth and polished, pronotal groove widely crenulate, few scattered setae along posterior and ventral margins. Mesonotum smooth and polished; mesoscutum with scattered setae medially and anteriorly, scutellar sulcus bare, scutellum with scattered setae along margin; notauli present on anterior 0.3 of the mesoscutum, narrow and distinctly crenulate dorsally; mid pit long, posteriorly elliptical and elongate anteriorly, 0.69–0.77x the length of mesoscutum; scutellum about as long as wide, smooth and polished; scutellar sulcus 0.29–0.33x longer than wide, with one median carina; mesoscutellar trough costate proximally, smooth distally. Metanotum without median carina; median region with small posterior beak; laterally costate with scattered setae. Mesopleuron mostly bare, with few scattered setae concentrated on anterior corner and ventrally; sternaulus long and crenulate, extending from epicnemial carina over half length of mesopleuron; anterior corner of mesopleuron smooth. Epicnemial carina present ventrally, incomplete. Metapleuron mostly smooth but ventrally rugose, with long and scattered setae. Propodeum mostly smooth with distinct mat surface (very fine fingerprint-like microsculpturing), some rugosity inside areola anteriorly; areola roughly pentagonal, with distinct cross-bridge and two pairs of transverse lateral carinae; median carina connected with areola, although irregular posteriorly. Hind coxa 1.75x longer than wide, 0.81–0.86x as long as metasomal TI. Hind basitarsus about 0.37–0.40x as long as hind tibia. Hind tarsal claws without basal lobe.

Wings. Fore wing. Stigma 3.4–3.6x longer than broad; vein r arising from middle of stigma. Vein r 0.46–0.50x longer than vein 3RSa. Vein 2RS straight, 0.75–0.79x longer than 3RSa. Vein 3 RSa 0.51–0.61 x 3 RSb and 1.9–2.0x as long as vein r-m. Vein 1 Cub 2.2–2.7x vein 1CUa. Vein (RS+M)b distinct, weakly pigmented. Vein 1-1AC 0.20– 0.29x longer than vein 2-1 A. Hind wing. Vein M +CU about 1.75x longer than 1M. Vein cu-a 0.53–0.66x as long as 1M. Vein r-m 0.65–0.68x as long as 1M.

Metasoma. TI 1.09–1.17x as long as apical width; rugose to areolate-rugose, laterally smooth; dorsal carinae short, present only basally, converging but not meeting; dorsope deep and large. Metasoma beyond petiole weakly sclerotized; TII about 1.6–1.8x longer than TIII. Ovipositor straight, 0.85–1.01x as long as hind tibia; ovipositor sheaths 0.87–0.91x longer than ovipositor.

Color. Head honey yellow with frons and vertex mostly brown. Mandibles light yellow, tips brown. Palpi white. Antenna with scapus and pedicel (sometimes first flagellomere) honey yellow, flagellum brown. Mesosoma brown with dark brown propodeum and lighter regions on pronotum laterally, mesopleuron ventrally, mesoscutum posteriorly, scutellum and metanotum. Legs whitish to pale light yellow; fore and mid fifth tarsomere, apical 1/3 of hind tibia and hind tarsi brown. Wings hyaline with brown veins.

Male. Unknown.

Biology. Unknown.

Comments. A. shawi sp. n. resembles A. itatiaia sp. n. in the long and crenulate sternaulus, differing from this species in having the clypeus 2.2–2.3x wider than high, as compared to about 1.5x in A. itatiaia sp. n., and the epicnemial carina well developed ventrally, as compared to weak or absent ventrally in A. itatiaia sp. n.

Distribution. Itatiaia and Serra da Bocaina National Parks, located in the Mantiqueira and Mar mountain chains respectively, both in the borders between São Paulo and Rio de Janeiro States. Altitudinal distribution ranging from 1,600 to 2,206 meters above sea level.

Etymology. This species is named after our colleague Scott R. Shaw for his contributions to the taxonomy and biology of Braconidae .

Type material. Holotype, female ( DCBU 22193 ): “ Itatiaia , RJ, Brasil / PARNA de Itatiaia / S 22°21’50.6” W 44°44’38.4” / Armadilha Malaise 4 (2.176 m) / 07.X.2011 / R.F. Monteiro col.”

Paratype (1♀) (DCBU 210521). Same as holotype, Malaise 5, S 22°21’36.9” W 44°43’56” (2,206 m): 1♀, 18. VI.2012.
