Material examined.

Holotype: PERU, ♀, Junín, Chanchamayo, Fundo Génova, 5-19.V.2008, Malaise Trap 2 (MEKRB, currently on loan in CEUA). Paratypes: PERU, 2 ♀♀, same locality, 05-19.IV.2008, Malaise Trap 4 (1 ♀, ZMUT; 1 ♀, CEUA).


Female. Body length (without ovipositor) 7.4-7.5 mm, head length × width 0.6-0.7 × 1.5-1.6 mm, mesosoma length × width (mesoscutum) 2.6 × 0.9-1.0 mm, length of ovipositor sheath 2.0-2.1 mm, fore wing length 5.9-6.1 mm, flagellum 9.2-9.3 mm.

Head. Transverse, 0.43 times as long as wide, strongly narrowed behind eyes, gena at same level as hind rim of eye (dorsal view). Antenna with 34-35 flagellomeres; flagellum longer than body, 1.47-1.55 times as long as fore wing (Fig. 2A); its segments 1, 4, 7 and 12 about 7.70, 5.00-5.60, 1.90-1.94 and 1.10 times as long as wide, respectively; basal flagellar segments 1 to 4 slightly compressed, flagellomeres 5 to 9-10 cylindrical, and from 11 to near apex depressed (flattened ventrally with short sensory setae in this area); maximum width of flagellum about 1.10 times the minimum width of segment 1; flagellum strongly tapered towards apex (Fig. 2A). Clypeus strongly convex, its margin sharp slightly truncate in centre (Fig. 1A). Mandible short, 2.30 as long as its width at middle, teeth equal or the lower tooth a little longer, base strongly swollen. Malar space about 0.80-0.90 times as long as basal width of mandible. Occipital carina absent dorsally, ventrally joining hypostomal carina just before mandible. Ocellar-ocular distance and distance between hind ocelli 1.16-1.25 and 1.40-1.50 times maximum diameter of lateral ocellus, respectively. Face coriaceous, with close, distinct but shallow punctures centrally and moderately long silvery hairs. Frons coriaceous. Vertex slightly coriaceous, with very sparse short hairs, lower vertex and occiput strongly concave; gena smooth and shiny, hairless in upper half, with moderately long and dense silvery hairs in lower part.

Mesosoma. Upper margin of pronotum not swollen. Lateral part of collar bordered behind by carina. Pronotum slightly coriaceous, laterally longitudinally strigose with sparse silvery hairs. Mesoscutum coriaceous, shiny, longitudinally strigose in the area between posterior part of notauli. Notauli reaching tegula level, convergent, strongly impressed with tight transverse wrinkles along its length. Prescutelar groove with longitudinal wrinkles. Scutellum weakly coriaceous, with complete lateral carina. Mesopleuron coriaceous, with very dense punctures and white long hairs; these hairs absent in an antero-posterior diagonal band that includes speculum. Mesopleural fovea absent or represented by a weak impression far in front of mesopleural suture. Sternaulus nearly absent. Metapleuron and propodeum finely and densely punctate or rugose-punctate on a coriaceous background, with very dense and long whitish hairs. Posterior transverse carina of mesosternum complete (not interrupted infront of each middle coxa). Propodeum long, its spiracle round and very small. Anterior transverse carina absent. Posterior transverse carina present in the centre and in area posteroexterna, absent laterally. Median longitudinal carinae of propodeum slightly distinct anterior to transverse carina; lateral longitudinal carina absent anterior to apical transverse carina, shortly present distad. Pleural carina strong, sometimes evanescent posteriorly. Area petiolaris confluent with areas posteroexterna. Vein 3rs-m un-pigmented. Vein 2rs-m 0.3 times length of abscissa of M between 2rs-m and 2m-cu. Vein 2m-cu vertical with one short bulla. Cu-a of fore wing a little distad of Rs&M. M+Cu of hind wing strongly arched. Hind wing with distal abscissa of Cu1 strong and pigmented. Cu1&cu-a strongly angled a little below middle. Distal abscissa of 1A of hind wing very short, nearly absent. Tip of axillus very close toanal margin. Tibiae and tarsi with sparse stout bristle, stronger on hind leg. Hind femur with 3-4 stout bristles on ventral (1-2) and dorsal (2) edge.

Metasoma. First tergite smooth and polished about 1.70-1.80 times as long as maximum width; its maximum width at apex about 3.30 times minimum width (at base). Median dorsal and dorsolateral carinae of first tergite absent, ventrolateral carinae more or less distinct posteriorly. Spiracle at anterior 0.30-0.40 of tergite. Tergites 2 square, polished, slightly coriaceous, laterally with short, sparse hairs; tergites 3-8 rather densely pubescent. Thyridium absent. Ovipositor sheath 0.62-0.66 times as long as hind tibia, widely truncate at apex (Fig. 3A). Ovipositor moderately slender and slightly down curved (Fig. 2A), its tip elongate lanceolate, nodus weak, its lower valve with three weak lateral ridges at apex.

Coloration (Fig. 2A). Head and mesosoma black, metasoma entirely, hind coxa, trochanter, trochantellus and femur, and ovipositor, vividly red. Mandible except base and teeth and scapus below, reddish brown. Band on flagellomeres 5-11 and tegula white. Fore, mid leg, hind tibia and tarsus (except distal tarsomere), yellow. All distal tarsomeres brown. Palpi, fore coxa, fore and mid trochanter and tochantelli, light yellow. Ovipositor sheath black.

Male. Unknown.

Taxonomic discussion.

This species differs from all other New World species by its coloration: head and mesosoma entirely black, and metasoma, hind coxa, trochanter, trochantellus, femur and tibia entirely red. The North American and Mesoamerican species Ateleute carolina  , Ateleute grossa  and Ateleute tinctoria  all have black and white patterns on the mesosoma and/or metasoma. Ateleute ashaninka  also differs from other South Ameri can species by its widely truncate black ovipositor sheath, more transverse head longer black antennae with 34-35 flagellomeres; and a larger body size.


This species is dedicated to the Peruvian Amazonian Ashaninka people, who live in the province of Chanchamayo, where the specimens were collected.


Adults fly in April-May.




The species was collected in a premontane rain forest area strongly perturbed by traditional agricultural activities represented by small Inga-shaded coffee plantations and maize and citrus cultivations. Large areas of the forest have been cut down, making way for the formation of secondary forest, grassland and degraded areas, but there are still some areas of primary forest left, due to their inaccessibility, selective extraction and policies of their owners. For more information on the vegetation and climate see Alvarado et al. (2011).
