Andesipolis brevisulcus sp. n. : 80, habitus; 81, face; 82, head and mesonotum, dorsal; 83, propodeum and metasoma, dorsal, 84, wings. Metasoma . TI 1.6x as long as apical width; rugose to areolate-rugose apically, laterally smooth; dorsal carinae extending over less than half length of tergum and not meeting, but basally connected by weak transverse carina; dorsope deep and large. Metasoma beyond petiole weakly sclerotized; TII about 2x longer than TIII. Ovipositor short and straight, 0.47x as long as hind tibia; ovipositor sheaths about as long as ovipositor. Color . Dark brown. Scapus and pedicel honey yellow. Mandibles yellowish with brown teeth. Palpi pale yellow. Pronotum honey yellow dorsally and ventrally, and brown posteriorly. Propleuron and mesopleuron honey yellow. Legs honey yellow, apical 1/3 of hind tibia and all tarsi brown. Male . Similar to female. Body length 2.2–2.3 mm ; antenna 2.6 mm and with 26 segments; fore wing length 2.4–2.5 mm . Biology. Unknown Comments. This species closely resembles A. cacildis sp. n. The face is about 2x broader than long in A. brevisulcus sp. n. as compared to about 1.5x broader than long in A. cacildis sp. n. The propodeum in A. brevisulcus sp. n. is smooth and polished with complete and roughly pentagonal areola. In A. cacildis sp. n. propodeum has a mat surface due to irregularly strigate microsculpturing and frequently incomplete and roughly triangular areola. These two species also differ in the short basal mid-longitudinal ridge on T1, present in A cacildis sp. n. but absent in A. brevisulcus sp. n. , and the mesopleuron dark brown in A. cacildis sp. n. , as compared with honey yellow in A. brevisulcus sp. n. Distribution. Known only from type locality at Itatiaia National Park, Rio de Janeiro , Brazil , at 2,255 m of elevation (montane grasslands). Etymology. The species name means “short furrow” and refers to its short midpit on mesoscutum. Material examined.
