Female. Body length 1.7–2.2 mm; fore wing length 1.8–2.3 mm.

Head. Smooth and mat (fingerprint-like microsculpturing) with scattered setae; 1.17–1.26x wider than mesoscutum. Face 1.48–1.67x broader than long, smooth and polished. Clypeus 2.41–2.66x broader than long. Malar space 0.39–0.44x eye height in frontal view. In lateral view, eyes 0.85–1.12x as long as temple. Maximum width of lateral ocellus 0.36–0.46x ocell-ocular distance. Antenna 0.8–0.9x as long as fore wing, 18–20 segmented; first flagellomere 5.0–5.5x longer than wide.

Mesosoma. 1.6–1.8x longer than high. Mesonotum about 1.3x longer than width of mesoscutum. Pronotum dorsally mostly smooth with two transverse parallel carinae, posterior region well above level of anterior region; as long as to slightly shorter than vertex, the posterior region about as long as anterior region; laterally smooth, few scattered setae along posterior margin. Mesonotum smooth and mat; mesoscutum with scattered setae anteriorly on median lobe and posteriorly, scutellum with scattered setae along margin; notauli crenulate anteriorly, dorsally weak and weakly crenulate, about 0.22x longer than mesoscutum; mid pit short and shallow, 0.33–0.37x length of mesonotum; scutellum 1.17–1.25x longer than wide, smooth and polished; scutellar sulcus 0.36–0.39x longer than wide, with one median carina; mesoscutellar trough mostly smooth, weakly costate just proximally. Metanotum without median carina; laterally smooth with scattered setae. Mesopleuron mostly bare, with few scattered setae on anterior corner and ventrally; sternaulus smooth and shallow. Epicnemial carina present ventrally, incomplete. Metapleuron mostly smooth but weakly rugose ventrally, with very few scattered setae. Propodeum smooth with long median carina; areola distinct posteriorly with distinct relatively high cross-bridge but absent anteriorly; posterior pair of transverse lateral carinae present, anterior pair absent. Hind coxa 1.60–1.75x longer than wide, 0.7–0.8x 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 narrow, 5.5–6.3x longer than broad; vein r arising from base of stigma. Vein r 0.33– 0.36x longer than vein 3RSa. Vein 2RS straight, 0.73–0.77x longer than 3RSa. Vein 3 RSa 0.41–0.44 x 3 RSb and 1.9–2.1x as long as vein r-m. Vein 1 Cub 1.98–2.45x vein 1CUa. Vein (RS+M)b short and not pigmented. Vein 1- 1AC 0.2–0.3x longer than vein 2-1 A. Hind wing. Vein M +CU 1.9–2.2x longer than 1M. Vein cu-a 0.57–0.60x as long as 1M. Vein r-m 0.6–0.7x as long as 1M.

Metasoma. TI 0.90–0.97x as long as apical width; smooth; dorsal carinae converging and meeting posteriorly; dorsope deep and large. Metasoma beyond petiole weakly sclerotized; TII about 1.4x longer than TIII. Ovipositor short and straight, 0.68–0.72x as long as hind tibia; ovipositor sheaths about 0.6x longer than ovipositor.

Color. Brown. Propleuron and metasoma beyond TI light brown. Legs and mandibles yellow except hind femur light brown. Mandible tips dark brown. Palpi whitish. Some specimens with pedicel and sometimes first flagellomere honey yellow. Wings hyaline, veins light brown, stigma whitish to pale light brown.

Male. Similar to female. Body length 1.7–2.0 mm; antenna with 17 or 19 segments; fore wing length 1.8–2.1 mm.

Biology. Unknown

Comments. This species resembles A. bicolor sp. n., A. flamengo sp. n. and A. whartoni in the absence of the anterior pair of transverse lateral carinae on propodeum, differing from them in having a high cross bridge enclosing a small areola. A. masneri sp. n. is distinct from these and all other Andesipolis species in several characters. The long and narrow stigma is a unique character of A. masneri sp. n. Other diagnostic characters are the relatively small eyes; antenna shorter than body; first metasomal terga smooth with dorsal carinae meeting posteriorly; body surface in general smoother and with less setae than other species.

Distribution. Known only from type locality in Conguillo National Park (1,150 m), Araucania Region, Chile.

Etymology. This species is named after our colleague Lubomir Masner, who collected the type specimens.

Type material. Holotype, female (CNC). “ CHILE: Cautín 1150 m / Conguillo Nat. Park / 4.ii.1988, Araucania / Nothofagus s.s. / L. Masner col.”

Paratypes. 12♀ and 5♂ (CNC), same data as holotype.
