Head. Smooth and polished, densely setose at frons and vertex (all head setose except part of gena/temple); 0.99–1.25x wider than mesoscutum; occipital carina bordered by a crenulate sulcus. Face 1.5–1.8x broader than long, smooth and polished. Clypeus 2.1–2.5x broader than long. Malar space 0.46–0.52x eye height in frontal view. In lateral view, eyes 0.75–1.24x as long as temple. Maximum width of lateral ocellus 0.26–0.36x ocell-ocular distance. Antenna as long as fore wing, 21–24 segmented; first flagellomere 3.3–3.8x longer than wide.

Mesosoma . 1.6–1.8x longer than high. Mesonotum 1.31–1.37x longer than width of mesoscutum. Pronotum dorsally with crenulate sulcus and distinct mid-longitudinal carina anteriorly, posteriorly rugose-crenulate with lateral longitudinal carina; about 0.8–0.9x longer than vertex, the posterior region slightly longer than anterior region; anterior region in distinct lower level as compared with posterior region; laterally smooth with crenulate pronotal groove, few scattered setae along posterior and ventral margin. Mesonotum smooth and polished; mesoscutum setose over entire surface, scutellar sulcus with scattered setae, scutellum with scattered setae concentrated along margin; notauli deep and wide, crenulate dorsally, about 0.29–0.37x length of mesoscutum; mid pit elliptical, shallow and wide, 0.50–0.63x length of mesoscutum; scutellum 1.0–1.2x longer than wide, smooth and polished; scutellar sulcus 0.34–0.37x longer than wide, with one median carina; mesoscutellar trough costate proximally, smooth distally. Metanotum without median carina; laterally weakly rugose, with scattered setae. Mesopleuron mostly bare, with scattered setae on anterior corner and ventrally; sternaulus crenulate; anterior corner of mesopleuron rugose. Epicnemial carina present ventrally, incomplete. Metapleuron mostly rugose, with long and scattered setae. Propodeum rugose anteriorly with median carina irregular; areola roughly pentagonal, with distinct cross-bridge and two pairs of transverse lateral carinae ( Fig. 23 ). Hind coxa 1.4–1.7x longer than wide, 0.60–0.79x as long as metasomal TI. Hind basitarsus about 0.34–0.39x as long as hind tibia. Hind tarsal claws without basal lobe.

Wings. Fore wing. Stigma 3.1–3.8x longer than broad; vein r arising from middle of stigma. Vein r 0.39–0.54x longer than vein 3RSa. Vein 2RS straight, 0.8–0.9x longer than 3RSa. Vein 3RSa 0.41–0.54 x 3 RSb and 1.8–2.0x as long as vein r-m. Vein 1Cub 1.7–2.0x vein 1CUa. Vein (RS+M)b short and not pigmented. Vein 1-1AC 0.2–0.3x longer than vein 2-1A. Hind wing. Vein M+CU 2.1–2.3x longer than 1M. Vein cu-a 0.6–0.8x as long as 1M. Vein rm 0.69–0.85x as long as 1M.

Metasoma. TI 1.2–1.6x as long as apical width; rugose with smooth latero-apical region; dorsal carinae converging but not meeting; dorsope deep and large. Metasoma beyond petiole weakly sclerotized, TII basally and all terga laterally slightly more sclerotized than remainder terga; TII about 2.0–2.3x longer than TIII. Ovipositor short and straight, 0.65–0.92x as long as hind tibia; ovipositor sheaths 0.55–0.77x longer than ovipositor.

Color. Honey yellow to light brown. Antenna darkening toward apex, apical segments brown. Head always with brown stains at stemmaticum and just behind eyes at temples, stain sometimes covering most of head dorsally. Mandibles yellow with dark brown tips. Palpi whitish. Mesosoma with propodeum and metapleuron dark brown; metanotum sometimes brown or dark brown; other dark brown regions are present in few specimens at: pronotum dorsally and laterally, mesopleuron anteriorly. The specimen from Cautín (1,150 m) is darker than others; the mesopleuron is mostly brown to dark brown. Metasoma with dark brown petiole, base of TII brown, remainder terga light brown to whitish dorsally, terga laterally darker. Legs stramineus; fore and mid tarsi light brown; hind leg with part of femur dorsally, tibia very basally and apical ¼ and tarsi light brown.

Male. Similar to female. Body length 2.7–3.3 mm; antenna with 2.6–3.8 mm and 22–28 segments; fore wing length 2.2–2.8 mm. The male from Cautín (1,150 m), like the female, is darker than usual.

Biology. Unknown

Comments. This species is distinct from others in the genus by the densely setose head and mesosoma , the crenulated sulcus bordering occipital carina, and honey yellow or light brown colored antenna darkening toward brown apex. Despite these characters A ona sp. n. resembles A. belshawi sp. n., being distinct from it by the welldefined propodeal areola, which is anteriorly undefined in A. belshawi sp. n., and the relatively short vein 1M of the hind wing, about 1.2x longer than vein r-m as compared with at least 2.5x in A. belshawi sp. n.

Distribution. Found in Chile and Argentina. This is the southernmost distributed species in the genus, occurring in Ushuaia, Tierra del Fuego.

Etymology. This species is named in honor of the Ona people, also known as Selknam. One of the several pre- Colombian ethnicities that lived in the southern South America, in the region now known as Patagonia, and being the same region where this species is distributed.
