Figs 6-10

Material examined. Holotype, female: COLOMBIA, Guaviare: Tomachipán ( playa río Inirida , 2°13’52”N, 71°31’31”W), 29.I.1999, F. Fernández leg. ( IAVH 31862 ) .

Description. Female. Body length 2.9 mm; LFW 134 mm. Color: body mostly black, palpi castaneous; mandible dark castaneous, median area of outer surface lighter; antenna dark castaneous, scape and flagellomeres infuscate; coxae and femora dark castaneous; trochanters castaneous; mid and hind tibiae dark castaneous, tarsi castaneous; tegula dark castaneous; wings hyaline, veins castaneous.

Head ( Fig. 6 ). Mandible with four teeth, lower tooth sharpened ( Fig. 8 ). Clypeus very short, median lobe rounded, median carina absent, base of clypeus extending back into frons. Eye sparsely hairy, situated forward on head. Antennal scrobe not carinate. Head very elongate, about 0.6x length of mesosoma, width of head barely larger than maximum mesosomal width; WH 0.80x LH; WF 0.50x WH; WF 1.0x HE; OOL 1.8x WOT; head 0.32x as high as long ( Fig. 7 ); frontal angle of ocellar triangle obtuse; posterior ocellus distant from vertex crest slightly more than own diameter. VOL 1.0x HE. Vertex concave medially with corner broadly rounded. First four antennal segments in ratio of about 10:5:2:3, segment III 1.0x as wide as long. Frons strongly coriaceous, surface above clypeus with polished flat linear elevation that does not surpass imaginary line between half length of eye. Sides of head parallel in lateral view. Palpal formula 6:3.

Mesosoma ( Fig. 6 ). With the same texture of frons. Pronotal disc with median width 1.64x median length; anterior margin conspicuously convex; posterior margin not paralleled by series of small foveae; length of pronotal disc/ mesoscutum/scutellum in about 2:1:1. Notaulus absent. Parapsidal furrow well impressed and straight, not reaching both anterior and posterior margins of mesoscutum. Scutellum wide posteriorly and broadly in contact with propodeal disc. Scutellar groove deep, progressively narrowing mesad, ends angled backward and not dilated. Propodeal disc 1.08x as long as maximum width, progressively narrowing posterad, anterior, median, lateral and posterior carinae complete, lateral carina not straight; propodeal disc strongly striate anteriorly; propodeal declivity short and striate; side-piece of propodeum coriaceous with weak striae. Mesopleuron with shallow large fovea occupying nearly entire surface of mesopleuron, outlined by carina; central pit small ( Fig. 9 ). Propleuron angulate in dorsal view. Mesosternum without striae or foveae, with shallow depression near margin of mid coxa. Fore wing with radial vein absent, basal vein with thickening medially ( Fig. 10 ). Mid tibia not spinose. Fore femur 2.2x as long as wide. Claws simple and much arched.

Metasoma. Wholly polished. Tergites and sternites with a row of setae posteriorly, former ones with few lateral setae. Posterior margin of sternites IV-VI evenly curved and bi-emarginate. Transverse section elliptical. Part exposed of sting 0.03 mm long. Length of metasoma 1.55x length of mesosoma.

Etymogeny. The specific epithet refers to the large size of the head.
