Holotype ♀ and one paratype ♂:

COLOMBIA, Nariño R. N., La Planada Parcela Olga, 1°15'N, 78°15'W, Malaise trap, holotype: 16 June - 2 July 2000 and paratype: 16 March - 2 April 2001, leg. G. Oliva. Holotype is in fairly good condition: (1) glued on a card point by lower part of mesopleuron,;(2) right flagellum broken, antenna with 19 antennomeres; (3) missing: right middle leg, right fore leg (except coxa) and tarsomeres 2-4 of left hind leg; (4) left fore wing apically missing beyond pterostigma. Paratype is also in fairly good condition: (1) glued on card point by meso- and metapleura; (2) left flagellum apically broken, antenna with 22 antennomeres; (3) missing tarsi of right fore and hind legs.

Etymology.

The new species is dedicated to its collector, Mr. G. Oliva.

Description.

Female: Body 3.6 mm long. Antenna long, twice as long as body, with 33 antennomeres. Flagellomeres very long, flagellomeres 1-2 equal in length and ten times as long as broad apically ( Fig. 34 ), subsequent flagellomeres slightly shortening so that penultimate flagellomere four times as long as broad. Head in dorsal view transverse ( Fig. 36 ), 1.8 times as broad as long, eye 4.5 times as long as temple, temple rounded, occiput weakly excavate. OOL somewhat more than twice as long as POL. Eye in lateral view 1.25 times as high as wide and 2.4 times as wide as temple, temple beyond eye evenly wide ( Fig. 37 ). Mandible 1.8 times as long below as broad between upper and lower teeth, fourth tooth between upper and middle teeth, every tooth pointed ( Fig. 20 ). Paraclypeal pit as long as distance between pit and compound eye ( Fig. 35 ). Segments of maxillary palp long, palp about 1.5 times as long as height of head. Head polished.

Mesosoma in lateral view stout, 1.2 times as long as high, polished. Pronope present. Crenulate notauli turning down to crenulated margin of mesoscutum, i.e. notauli not extending onto declivous anterior part of mesoscutum ( Fig. 22 , see arrow). Notauli meeting posteriorly (before prescutellar furrow) and here dimple missing. Prescutellar furrow subcrenulate, laterally from furrow (or on axillae) with pair of lamelliform excrescenses ( Fig. 23 ). Metanotum medially with fairly long and somewhat posteriorly curved spine ( Fig. 24 ). Propodeum areolate, areolae polished, spiracles before middle of propodeum, carination strong ( Fig. 38 ). Precoxal suture distinct, restricted to middle of mesopleuron, crenulate, hind margin of mesopleuron almost smooth to subcrenulate; epicnemial carina present. Legs long. Hind femur 5.5 times as long as broad distally ( Fig. 39 ). Hind tibia almost 1.3 times as long as hind tarsus.

Pterostigma ( Fig. 21 ) 6.6 times as long as wide and r issuing from its middle, r short, shorter than width of pterostigma. Second submarginal cell long, 3-SR 1.6 times as long as 2-SR, n. rec. interstitial, SR1 1.6 times as long as 3-SR and reaching tip of wing. First subdiscal cell narrowing distally and closed ( Fig. 40 , see horizontal arrow), CU1a interstitial ( Fig. 40 , see vertical arrow).

First tergite ( Fig. 33 ) 1.8 times as long as broad behind, weakly broadening posteriorly, spiracles before middle of tergite; pair of basal keels meeting at spiracle and posteriorly diverging, reaching hind end of tergite. Hind half of tergite medially between keels longitudinally substriate, otherwise polished. Tergites 2-3 fused and as long as first tergite, together with further tergites polished ( Fig. 33 ). Ovipositor sheath as long as first tergite or hind basitarsus + half of second tarsomere.

Ground colour of body yellow to brownish yellow. Scape and pedicel brownish yellow. Flagellum brown to dark brown, flagellomeres 19-25 white. Head brownish yellow, vertex brown. Mandible, mouthparts, palps pale yellow. Prothorax browish yellow, mesoscutum, scutellum and mesosternum brown. Mesopleuron and propodeum blackish brown. Tergites brown, sternites yellow. Legs yellow, coxae and trochanters lemon yellow. Wings hyaline, pterostigma and veins yellowish.

Description.

Male paratype. Similar to female holotype. Body 3.5 mm long. Antenna with 31 antennomeres. Head in dorsal view 1.8 times as broad as long. Ptero-stigma wide, 5.7 times as long as wide. Dark colour somewhat more extensive.

Host.

Unknown.

Distribution.

Colombia.
