Head. Transverse, 0.70 times as long as wide, strongly narrowed behind eyes, gena at same level as hind rim of eye (dorsal view). Antenna with 28-29 flagellomeres; flagellum slightly longer than body, 1.55-1.65 times as long as fore wing ( Fig. 9B ); its segments 1, 4, 7 and 12 (and most of following segments) about 9, 7, 3 and 1.10 times as long as wide, respectively; basal flagellar segments 1 to 9 compressed or slightly cylindrical and flagellomeres 10-11 and following depressed (flattened ventrally and this flattened area covered with short sensory setae); maximum width of flagellum about twice minimum width of first flagellomere; flagellum strongly tapered towards apex ( Fig. 9B ). Clypeus convex, almost triangular, with apex produced into acute point, about once as long as distance between clypeal foveae ( Figs 1C , 9F ). Mandible short, about 2 times as long as width at the middle, teeth with the lower tooth slightly longer. Malar space about 0.80-0.90 times as long as basal width of mandible ( Fig. 9F ). Occipital carina absent dorsally, ventrally joining hypostomal carina just before mandible. Ocellar-ocular distance and distance between hind ocelli 1.00 and 1.20 times maximum diameter of lateral ocellus, respectively. Face coriaceous, matt and with moderately long silvery hairs ( Fig. 9F ). Frons matt, coriaceous. Vertex slightly coriaceous, with very sparse short hairs, lower vertex and occiput centrally concave; gena slightly coriaceous, occiput and gena with scattered silvery hairs.

Mesosoma. Upper margin of pronotum not swollen. Lateral part of collar without carina. Pronotum coriaceous, laterally longitudinally strigose with sparse silvery hairs. Mesoscumum coriaceous, shiny, slightly strigose in the area between posterior end of notauli. Notauli reaching tegula level, convergent, strongly impressed and without clear transverse wrinkles along its length. Prescutelar groove with longitudinal wrinkles. Scutellum weakly coriaceous, with lateral carinae present only at anterior end of the scutellum. Mesopleurum coriaceous, with very dense punctures and white long hairs. Mesopleural fovea present far in front of mesopleural suture. Sternaulus present and reaching approximately middle length of mesopleurum. Metapleurum and propodeum densely punctate or rugose-punctate on a coriaceous background, with dense and whitish hairs. Posterior transverse carina of mesosternum complete (not interrupted in front 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, slightly undulating along its length. Median longitudinal carinae of propodeum absent; lateral longitudinal carina absent anterior to apical transverse carina, present distad. Pleural carina strong. Area petiolaris confluent with areas posteroexterna. Vein 2 rs-m very short, about 0.20 length of M ( Fig. 1D ). Vein 2 m-cu almost vertical and with one short bulla. M+Cu of hind wing strongly arched. Hind wing with distal abscissa of Cu 1 pigmented. Vein cu-a clearly shorter than abscissa of Cu between M and Cu 1 ( Fig. 9I ). Distad abscissa of 1 A of hind wing short. Base of hind coxa of moderate depth, with a short transverse shallow groove next to its attachment. Tibiae and tarsi with sparse and stout bristles, bristles stronger on hind leg.

Metasoma. First tergite smooth, polished, very slightly coriaceous and about twice as long as maximum wide; its maximum width at apex about 3 times minimum width (at base). Median dorsal and dorsolateral carinae of first tergite absent, ventrolateral carinae more or less distinct posteriorly. Spiracle at mid length of first tergite. Tergites 2-3 smooth and polished, laterally with short, sparse hairs; tergites 4-8 rather densely pubescent. Thyridium present as short impressed and granulate furrow. Ovipositor sheath about 0.50 times as long as hind tibia, truncate at apex. Ovipositor moderately slender and slightly down curved ( Fig. 9B ), its tip elongate lanceolate, nodus weak, its lower valve with a few weak and oblique ridges at apex.

Coloration ( Fig. 9B ). Head blackish with mandibles (except of brown teeth), palpi, clypeus, face, gena and orbits mostly white or creamy white. Antenna dark brown with scape whitish and broad white band on flagellar segments 7-16. Mesosoma reddish with whitish marks on anterior side of pronotum and subtegular area. Legs mostly creamy whitish to light brown with darker brown coloration in hind coxa, trochanter and trochantellus of mid and hind leg, and all distal tarsomeres. Metasoma dark brown with broad whitish bands on hind edges of tergites 1-3 and with a very narrow apical whitish band on other tergites, except the seventh, which is entirely brown. Ovipositor sheath dark brown, ovipositor yellowish.

Male. Unknown.

Taxonomic discussion.

This species differs from all other species of the genus by the following characters in combination: mesoscutum and scutellum reddish, without white V-shaped marks; face with broad white orbits; metasoma dark brown with broad whitish bands on hind edges of tergites 1-3 and with a very narrow apical whitish band on other tergites except the seventh, which is entirely brown; and hind wing vein cu-a clearly shorter than abscissa of Cu between M and Cu 1.

Remarks.

There is some variation especially in the coloration of the face (some specimens have a slightly darker face).

Etymology.

This species is dedicated to the Peruvian Amazonian Bora people, who live in the vicinity of the type locality (Department of Loreto, Peru).

Phenology.

Adults fly in July-August and December-January.

Distribution.

Ecuador and Peru.

Habitat.

The Peruvian type locality (the National Reserve of Allpahuayo-Mishana) of Tamaulipeca bora sp. n. is situated in a complex mosaic of different kinds of rain forest types (e.g. Sääksjärvi et al. 2004). In flat low-lying areas, soils are often clayey in texture, relatively rich in nutrients, and mainly brownish-grey in colour. Soils on hilltops are often composed of so-called white sand, which is of quartzitic mineralogy, very nutrient poor, and grey to white in colour. Also loamy soils of intermediate nutrient content occur in the area. Tamaulipeca bora has been collected by Malaise trapping in rain forests growing on both white sand (one paratype) and clayish soils (holotype and 2 paratypes). One paratype has been collected by canopy fogging in Onkone Gare, Department of Orellana, Ecuador, in the same habitat as Ateleute huaorani .
