Type material. Holotype female ( NMNH, currently on loan to ZMUT). Ecuador, Dept. of Orellana, Onkone Gare 00°39’25.7” S, 076°27’10.8” W, 220 m elev. Terry L. Erwin leg. Canopy fogging, 25. VI.1994 . Paratype female ( BMNH) ‘ Ecuador: Napo, Panacocha. 12.III.1998 M. Cooper. M. Cooper coll. BMNH ( E) 2005-152 ’

Female ( Fig. 5 ). Head in dorsal view moderately short, with genae evenly narrowed behind eyes; frons weakly biconcave; posterior ocellus separate from eye by 0.6-0.7 times its own diameter; occipital carina complete, ventrally, laterally and dorsally expanded into a very high membranous flange ( Fig. 8 ); clypeus relatively flat, basally not clearly separated from face; clypeal apex truncate; malar space 0.4 times as long as basal mandibular width; face polished and pubescent, about 1.0 times as wide as medially high. Pronotum with apical edge strongly reflexed and raised, overlapping propleura ( Fig. 9 ). Mesoscutum pubescent, with notauli strongly impressed anteriorly, bounded in front by high triangular crests ( Fig. 9 ); scutellum convex, laterally with high carinae. Mesopleuron polished, with ventral part densely pubescent; epicnemial carina reaching to well above level of lower corner of pronotum, ventrally strongly raised. Metapleuron weakly convex, smooth; submetapleural carina sharp but low, extending back to insertion of hind coxa. Propodeum in profile abruptly declivous ( Fig. 7 ); anterior transverse carina present except centrally, where it is curved forward joining lateromedian longitudinal carinae; posterior transverse carina complete and medially horizontal; lateromedian longitudinal carina present anteriorly and weakly present centrally, defining area superomedia ( Fig. 6 ); lateral longitudinal carina present, stronger above spiracle; pleural carina complete. Hind tibia with sub-apical patch of three or four strong bristles, one bristle separate at tibia apex. Fourth tarsomere about 0.7 times as long as broad. Fore wing length 10- 12mm; areolet complete; vein Rs sinuous; cu-a opposite or slightly basal to Rs&M; discosubmarginal cell evenly, quite closely hirsute. Tergite 1 of metasoma about 1.3 times as long as posteriorly broad, with lateral longitudinal and lateromedian longitudinal carina strongly developed anteriorly, anterior part of tergite 1 with strong glymma; tergite 2 with a more or less rhombic raised central area; tergites 2 and 3 with posterior transverse grooves strongly, longitudinally costate, sculpture weaker on successive tergites. Claws of hind leg large, without a basal lobe and with four strong hairs at the base, one of them exceeding the tip of the claw. Ovipositor sheath 0.8 times as long as hind tibia ( Fig. 5 ); apex of ovipositor evenly tapered, decurved, with denticles on upper valve.

A pale yellow species with transverse black bands across the mesoscutum centrally, the region of the scuto-scutellar groove and the anterior part of the propodeum. Interocellar area, stripes leading from posterior ocelli to large, dorso-lateral patches on occipital area, mesosternum and posterior margin of mesopleuron black. Tergites orange with posterior margin of tergites 1-3 yellowish. Scape yellow in frontal view and brownish dorsally. Antennal flagellum brown, paler ventrally but entirely dark apically, except apical flagellomere distally orange. Ovipositor sheath proximally yellowish, infuscate distally. Wings slightly yellowish, pterostigma yellowish.

Male. Unknown

Diagnosis. Th is species can be distinguished from all other Neotropical species of the genus by a combination of the following characters: occipital carina forming a vertical flange, posterior transverse carina medially horizontal and lateral carina present, defining area dentipara.

Biological notes. Nothing is known about the hosts of this species.

Etymology. This species is named in honour of Dr. Reijo Jussila, Finnish ichneumonologist, who has dedicated 50 years of his life to studying the taxonomy of the family Ichneumonidae and supervising younger researchers.
