Female. Body length 1.8–2.6 mm; fore wing length 1.8–2.6 mm

Head. Smooth and polished, with scattered setae, some specimens virtually bare at frons and vertex; 1.2–1.4x wider than mesoscutum. Face 1.38–1.57x broader than long, smooth and polished. Clypeus 2.04–2.35x broader than long. Malar space 0.47–0.51x eye height in frontal view. In lateral view, eyes 0.97–1.23x as long as temple. Maximum width of lateral ocellus 0.31–0.42x ocell-ocular distance. Antenna 1.15–1.25x longer than fore wing, 21–28 segmented; first flagellomere 4.1–5.8x longer than wide.

Mesosoma . 1.8–2.0x longer than high. Mesonotum 1.35–1.47x longer than width of mesoscutum. Pronotum dorsally with crenulate sulcus and distinct mid-longitudinal carina anteriorly, posteriorly rugose-crenulate with arched carina enclosing a crescent moon shaped area; about 0.8–1.0x longer than vertex, the posterior region slightly longer than anterior region; anterior region in distinct lower level as compared with posterior region; laterally smooth, pronotal groove crenulate but frequently smooth medially, few scattered setae along posterior and ventral margin. Mesonotum smooth and polished; mesoscutum setose over entire surface, scutellar sulcus with a line of scattered setae; scutellum mostly bare, with scattered setae along margin; notauli crenulate dorsally, 0.30– 0.36x length of mesonotum; mid pit more or less elliptical, 0.48–0.57x length of mesoscutum; scutellum 1.23– 1.43x longer than wide, smooth and polished; scutellar sulcus 0.33–0.39x longer than wide, with one median carina; mesoscutellar trough costate proximally, smooth distally. Metanotum without median carina, median region rugose at posterior apex; laterally rugose and weakly costate posteriorly, with scattered setae. Mesopleuron mostly bare, with few scattered setae concentrated on anterior corner and ventrally; sternaulus smooth to crenulate, getting close to epicnemial carina anteriorly; anterior corner of mesopleuron smooth to weakly rugose. Epicnemial carina present ventrally, incomplete. Metapleuron ventrally rugose, with long and scattered setae. Propodeum rugose anteriorly with median carina irregular; areola roughly triangular to indistinct anteriorly, with distinct cross-bridge and two pairs of transverse lateral carinae ( Fig. 22 ). Hind coxa 1.7–1.9x longer than wide, 0.70–0.97x as long as metasomal TI. Hind basitarsus about 0.37–0.42x as long as hind tibia. Hind tarsal claws without basal lobe.

Wings. Fore wing. Stigma 4.2–4.5x longer than broad; vein r arising from middle of stigma. Vein r 0.44–0.60x longer than vein 3RSa. Vein 2RS straight to weakly sinuate, 0.94–1.13x longer than 3RSa. Vein 3RSa 0.36–0.46 x 3 RSb and 1.63–2.21x as long as vein r-m. Vein 1Cub 1.9–2.5x vein 1CUa. Vein (RS+M)b distinct, not pigmented. Vein 1-1AC 0.2–0.3x longer than vein 2-1A. Hind wing. Vein M+CU 1.2–1.4x longer than 1M. Vein cu-a 0.34– 0.41x as long as 1M. Vein r-m 0.32–0.39x as long as 1M.

Metasoma. TI 1.08–1.24x as long as apical width; rugose with smooth latero-apical region; dorsal carinae short, converging but not meeting; dorsope deep and large. Metasoma beyond petiole weakly sclerotized; TII about 1.4–1.8x longer than TIII. Ovipositor short and straight, 0.53–0.79x as long as hind tibia; ovipositor sheaths 0.61– 0.86x longer than ovipositor.

Color. The most common coloration of this species is: head and antenna brown, mesosoma and legs mostly honey yellow but propodeum brown, metasoma pale light brown with brown petiole; however, some specimens are entirely brown or light brown. Mandibles honey yellow, tips brown. Palpi whitish. Wings hyaline, veins light brown to brown, stigma translucent to whitish.

Male. Similar to female. Body length 1.6–2.3 mm; antenna with 1.8–2.5 mm and 20–22 segments; fore wing length 1.5–2.2 mm. Metasoma slender, TI 1.5–1.6x longer than apical width.

Biology. Unknown

Comments. Andesipolis belshawi sp. n. is similar to A. masoni but has smaller wings (2.5–2.7 vs 3.5 mm), relatively smaller eyes (about 1.0–1.2x longer than temple in belshawi vs 1.6–1.8x in masoni ), antenna with fewer segments (22–25 in A. belshawi sp. n. compared with 27–29 in A. masoni ), and shorter ovipositor (about 0.5–0.7x longer than hind tibia in A. belshawi sp. n. as compared with 0.8–0.9 in A. masoni ). The color pattern of these two species is different: the mesosoma in masoni is mostly yellowish except for propodeum and scutellar sulcus brown, while the color of the mesosoma is variable in A. belshawi sp. n., being mostly brown in some specimens, but never yellowish with a brown scutellar sulcus.

Distribution. This seems to be the most common species of Andesipolis in Chile. The species is common in Osorno province, including Chiloe Island, and also from Mocha Island. The northernmost and also higher altitudinal record of the species is from Reserva Nacional Nuble (72 km SE Chillán), at 1,700 m elevation.

Etymology. The species is named in honor to Robert Belshaw, for his contributions on the studies of Mesostoinae evolution and biogeography.
