Andesipolis pseudoscapus Shimbori & Penteado-Dias   sp. n.

( Figs 10 View FIGURES 2 – 13 , 42 View FIGURES 39 – 42 , 55 View FIGURES 47 – 55 , 139–144 View FIGURES 139 – 144 )

Female. Body length 2.3–2.9 mm; fore wing length 2.6–3.2 mm.

Head. Smooth and polished, with scattered setae; about 1.2x wider than mesoscutum. Face about 1.9x broader than long, smooth and polished. Clypeus 2.5–2.9x broader than long. Malar space 0.5–0.6x eye height in frontal view. In lateral view, eyes 1.0–1.2x longer than temple. Maximum width of lateral ocellus about 0.3x ocell-ocular distance. Antenna about as long as fore wing, 25–29 segmented; first flagellomere 3.5–3.8x longer than wide; torulli unusually expanded, shaped as a short additional scape.

Mesosoma   . About 1.7–1.8x longer than high. Mesonotum 1.34–1.46x longer than width of mesoscutum. Pronotum with both anterior and posterior sulcus crenulate, separated by weak transverse carina and short smooth area; 0.7–0.8x longer than vertex, the posterior region about 1.6–1.7x longer than anterior region; laterally smooth with few scattered setae along posterior and ventral margins; pronotal groove crenulate anteriorly and posteriorly, medially smooth. Mesonotum smooth and polished; mesoscutum mostly covered with scattered setae, scutellar sulcus bare, scutellum with scattered setae along margins; notauli present on anterior 0.23–0.28 of the mesoscutum, weakly impressed and virtually smooth except weak crenulation anteriorly; mid pit narrow and shallow, 0.33– 0.44x the length of mesoscutum; scutellum 1.25x as long as wide, smooth and polished; scutellar sulcus 0.27– 0.29x longer than wide, with one median carina; mesoscutellar trough costate proximally, smooth distally. Metanotum without median carina; laterally costate along posterior margin, with sparse setae. Mesopleuron mostly bare, with scattered setae on anterior corner and ventrally; sternaulus short and crenulate. Epicnemial carina present ventrally, incomplete. Metapleuron rugose posteriorly to mostly rugose with smooth area dorsally, covered with long and scattered setae. Propodeum rugose with median-basal area smooth and polished; areola varying from indistinct to distinct though irregular anteriorly, with distinct cross-bridge and two pairs of transverse lateral carina; median carina relatively short. Hind coxa 1.6–1.9x longer than wide, 0.8–1.0x as long as metasomal TI. Hind basitarsus about 0.39–0.41x as long as hind tibia. Hind tarsal claws without basal lobe.

Wings. Fore wing. Stigma 4.0–4.2x longer than broad; vein r arising at middle of stigma. Vein r 0.3–0.4x longer than vein 3RSa. Vein 2RS weakly curved, 0.61–0.79x longer than 3RSa. Vein 3RSa about 0.6–0.8 x 3 RSb and 2.0–2.5x longer than vein r-m. Vein 1Cub 1.9–2.1x vein 1CUa. Vein (RS+M)b very short or absent. Vein 1- 1AC very short or virtually absent, less than 0.23–033x longer than vein 2-1A. Hind wing. Vein M+CU 1.3–1.5x longer than 1M. Vein cu-a about 0.40–0.57x as long as 1M. Vein r-m 0.44–0.57x as long as 1M.

Metasoma. TI 1.3–1.5x as long as apical width; striate-rugose, apico-laterally smooth; dorsal carinae short, present only basally, converging but not meeting; dorsope deep. Metasoma beyond petiole weakly sclerotized; TII 1.5–1.9x longer than TIII. Ovipositor curved upward, 0.7–1.0x as long as hind tibia; ovipositor sheaths 0.5–0.7x as long as ovipositor.

Color. Dark brown to black. Mandibles honey yellow. Palpi whitish. Some specimens with lighter brown patches at mesoscutum posteriorly and mesopleuron ventrally. Metasoma beyond TI brown. Legs honey yellow with brown tibia and tarsi, hind coxa brown to dark brown. Wings hyaline, veins and stigma light brown, stigma whitish in some specimens.

Male. Male. Body size 2.0– 2.8 mm; antenna 25–29 segments. Similar to female but TI slender 1.7–1.8x longer than apical width, as compared with 1.3–1.5 in females.

Biology. Unknown

Comments. This species closely resembles A. yanayacu   in the curved ovipositor, the tarsal claw without basal lobe and the main dark brown body color. It can be distinguished by the elongated torulli, which resembles a second scape, and also the petiole comparatively slender than in A. yanayacu   (about as long as apical width in yanayacu   vs. 1.3–1.5x in A. pseudoscapus   sp. n.) Other distinguishing features are the antenna with less flagellomeres (25–29 segments in A. pseudoscapus   sp. n. vs 31–32 segments in A. yanayacu   ) and the stigma slightly broader (4.0 longer than broad in A. pseudoscapus   sp. n. vs 4.6 in A. yanayacu   ). The hypostomal carina is distinct and complete in this species, and clearly meeting occipital carina ventrally.

Distribution. This species is recorded in the Andes mountains of Ecuador and Colombia, above 3,200 meters of elevation.

Etymology. The name of this species is a reference for the expanded torulli projection, which resembles a false scapus.
