Tamaulipeca sp. Fig. 9D

Material examined.

ECUADOR, 1 ♂, Dept. Orellana, Tiputini, 0°37'55.7"S, 76°8'39"W, Canopy fogging, 220-250 m., 6.II.1999, T. L. Erwin et al. Lot.1802 (USNM).

Male. Body length about 3.4 mm, head length × width 0.6 × 0.9 mm, mesosoma length × width (mesoscutum) 1.4 × 0.5 mm, fore wing length 3.5 mm, flagellum 5.0 mm.

Head. Transverse, 0.70 times as long as wide, strongly narrowed behind eyes, gena slightly rounded (dorsal view). Antenna with 25 flagellomeres; flagellum longer than body, 1.40 times as long as fore wing ( Fig. 9D ). Clypeus convex, triangular, pointed at apex. Mandible about twice as long as width at middle, teeth equal (upper tooth slightly broken). Malar space about 0.40 times as long as basal width of mandible. Occipital carina absent dorsally, ventrally joining hypostomal carina before mandible. Ocellar-ocular distance and distance between hind ocelli 1.0 and 1.40 times maximum diameter of lateral ocellus, respectively. Face finely coriaceous, with sparse setiferous punctures, the hairs short and silvery. Frons finely coriaceous and shiny. Vertex slightly coriaceous, elevated above the eye level, abruptly folded behind hind ocelli in a vertical lower vertex, lower vertex and occiput smooth and shiny, deeply concave in the centre; gena shiny, slightly coriaceous, hairless in upper half, with silvery hairs in lower part.

Mesosoma. Upper margin of pronotum not swollen. Lateral part of collar without carina. Pronotum slightly coriaceous, shortly longitudinally strigose on lower hind corner. Mesoscutum slightly coriaceous, shiny. Notauli reaching tegula level, convergent. Prescutelar groove almost smooth, at most with very weak longitudinal wrinkles. Scutellum slightly coriaceous, with lateral carinae present only at anterior end. Mesopleuron coriaceous with short and sparse white hairs. Sternaulus slightly impressed anteriorly. Mesopleural fovea represented by a weak impression far in front of mesopleural suture. Metapleuron punctate or rugulose-punctate on a slightly coriaceous background, with short whitish hairs. Propodeum long, granulate, its spiracle round and very small. Anterior transverse carina absent. Posterior transverse carina present in the centre, absent laterally. Median longitudinal carinae of propodeum absent, lateral longitudinal carina almost absent, only present prior to posterior transverse carina. Pleural carina strong. Areolet completely absent, without any trace of 3 rs-m un-pigmented. Hind wing with distal abscissa of Cu 1 pigmented. Vein cu-a shorter than abscissa of Cu between M and Cu1. Distad abscissa of 1 A of hind wing present but not complete. Tibiae and tarsi with sparse stout bristles, stronger and denser on hind leg. Hind femur with some stout bristles on dorsal and ventral edge.

Metasoma. First tergite smooth and polished, about 2.20 times as long as width, laterally with isolated short silvery hairs. Median dorsal carinae of first tergite absent, dorsolateral carinae present at base, ventrolateral carinae present at middle. Spiracle at anterior 0.4 of first tergite. Tergite 2 shiny and slightly coriaceous, with short and very sparse hairs laterally. Tergites 3-8 coriaceous, rather densely pubescent. Thyridium weak, present as a weak transverse and yellowish depression. Claspers slightly triangular at apex, however, apex widely, not narrowly, pointed.

Coloration ( Fig. 9D ). Blackish to darkbrown. Mandibles, palpi, front and mid legs, hind femora and tarsi (except distal tarsomeres) from orange to light yellowish. Second and third tarsomeres of middle and hind tarsi whitish. Wings clear with veins and pterostigma dark brown.

Remarks.

We have not been able to link this male with any of the Tamaulipeca females we have seen. It seems that the male is not Tamaulipeca candoshi as hind wing vein cu-a is shorter than the abscissa of Cu between M and Cu 1.

Habitat.

The specimen was collected by canopy fogging in Tiputini, Department of Orellana, Ecuador. Vegetation at the site is old and diverse primary rain forest growing on relatively nutrient-rich soils.
