Type material.

Holotype: ECUADOR • 1♀; EC-12684, YY-A091; Napo, Yanayacu Biological Station, Río Cosanga, Plot 188; cloud forest; 2,145 m; - 0.595917, -77.880017; 01.iii.2006; María de los Angeles Simbaña leg.; caterpillar collected in second instar; cocoons formed on 07.iv.2006; adult parasitoids emerged on 24.iv.2006; ( PUCE) . Paratypes. • 11 (4♀, 3♂) (4♀, 0 ♂); EC-12684, YY-A091; same data as for holotype; ( PUCE) .

Diagnosis.

Petiole on T1 with lateral margin straight throughout ( Fig. 186G, H ), fore telotarsus proximally narrow, distally wide, dorsal furrow of pronotum without a smooth band ( Fig. 186A, I ), petiole with a mix of fine rugae and coarse sculpture over most of the surface ( Fig. 186G, H ), propodeum rather coarse sculpture, with transverse rugae ( Fig. 186F ), fore wing with vein 1 cu-a straight, r vein curved, outer side of junction of r and 2RS veins not forming a stub ( Fig. 186K ), dorsal outer depression on hind coxa present ( Fig. 186A, J ), inner margin of eyes diverging slightly at antennal sockets ( Fig. 186B ), and lateral grooves delimiting the median area on T2 clearly defined and reaching the distal edge of T2 ( Fig. 186G, H ).

Coloration

( Fig. 186 A–L ). General body coloration black except labrum, mandibles, lateral ends of metapleuron, ventral furrow of pronotum, and metapleuron with brown/reddish tints; glossa, maxillary and labial palps, and tegulae yellow; pedicel yellow-reddish; scape and all antennal flagellomeres (on both sides) dark brown/black. Eyes and ocelli silver. Fore and middle legs dark yellow except claws brown, although femora, tibiae and tarsomeres with a narrow dorsal strip brown from top to bottom; hind legs dark yellow except coxae black distally brown/reddish, (coloration brown/reddish cover more area in the inner side), femora dorsally with a tiny brown spot, additionally with a narrow dorsal brown strip from top to bottom, tibiae with both ends brown, and tarsomeres brown. Petiole on T1 black and sublateral areas yellow; T2 with median area black, very narrow adjacent area dark brown, thus contours of median area looks darker, and lateral ends yellow; T3 light brown except lateral ends proximally yellow-brown; T4 and beyond light brown; distally each tergum with a narrow yellowish transparent band. In lateral view, T1-2 yellow; T3 yellow, but dorsally brown; T4 and beyond brown-reddish. S1-2 yellow; S3 yellow, but medially brown; S4 and beyond brown.

Description.

Head ( Fig. 186 A–D ). Head rounded with pubescence long and dense. Proximal three antennal flagellomeres longer than wide (0.22:0.05, 0.21:0.05, 0.22:0.05), distal antennal flagellomere longer than penultimate (0.13:0.05, 0.11:0.05), antenna longer than body (3.08, 2.38); antennal scrobes-frons shallow. Face convex, punctations barely noticeable, interspaces wavy and longitudinal median carina present. Frons smooth. Temple wide, punctate-lacunose and interspaces wavy. Inner margin of eyes diverging slightly at antennal sockets; in lateral view, eye anteriorly convex and posteriorly straight. POL shorter than OOL (0.08, 0.12). Malar suture absent or difficult to see. Median area between lateral ocelli without depression. Vertex laterally rounded and dorsally wide.

Mesosoma ( Fig. 186A, E, F, I ). Mesosoma dorsoventrally convex. Mesoscutum 1/4 distal with a central dent, punctation distinct proximally, but absent/dispersed distally, interspaces wavy/lacunose. Scutellum long and slender, apex sloped and fused with BS, but not in the same plane, scutellar punctation scattered throughout, in profile scutellum flat and on same plane as mesoscutum, phragma of the scutellum partially exposed; BS only very partially overlapping the MPM; ATS demilune with complete undulate/reticulate carinae; dorsal ATS groove smooth. Transscutal articulation with small and heterogeneous foveae, area just behind transscutal articulation depressed centrally and with same kind of sculpture as mesoscutum. Metanotum with BM convex; MPM circular without median longitudinal carina; AFM with a small lobe and not as well delineated as PFM; PFM thick, smooth and with lateral ends rounded; ATM proximally with a groove with some sculpturing and distally smooth. Propodeum rather coarse sculpture, with transverse rugae, proximal half curved; distal edge of propodeum with a flange at each side and without stubs; propodeal spiracle distally framed by a short transverse carina; nucha surrounded by long radiating carinae. Pronotum virtually without trace of dorsal furrow, dorsally without a smooth band; short parallel carinae only in ventral furrow. Propleuron with fine punctations throughout and dorsally without a carina. Metasternum convex. Contour of mesopleuron convex; precoxal groove smooth, shiny and shallow, but visible; epicnemial ridge convex, teardrop-shaped.

Legs. Ventral margin of fore telotarsus excavated with conspicuous curved seta over this excavation, fore telotarsus proximally narrow and distally wide, and longer than fourth tarsomere (0.18, 0.07). Hind coxa with dorsal half sparsely punctate, ventral half densely punctate, and dorsal outer depression present. Inner spur of hind tibia longer than outer spur (0.23, 0.20), entire surface of hind tibia with dense strong spines clearly differentiated by color and length. Hind telotarsus longer than fourth tarsomere (0.17, 0.14).

Wings ( Fig. 186K, L ). Fore wing with r vein slightly curved; 2RS vein slightly convex to convex; r and 2RS veins forming a weak, even curve at their junction and outer side of junction not forming a stub; 2M vein slightly curved/swollen; distally fore wing [where spectral veins are] with microtrichiae more densely concentrated than the rest of the wing; anal cell 1/3 proximally lacking microtrichiae; subbasal cell with microtrichiae virtually throughout; vein 2CUa absent and vein 2CUb spectral; vein 2 cu-a absent; vein 2-1A proximally tubular and distally spectral, although sometimes difficult to see; tubular vein 1 cu-a straight, incomplete/broken and not reaching the edge of 1-1A vein. Hind wing with vannal lobe narrow, subdistally and subproximally straightened, and setae evenly scattered in the margin.

Metasoma ( Fig. 186A, G, H, J ). Metasoma cylindrical . Petiole on T1 with a mix of fine rugae and coarse sculpture over most of the surface, virtually parallel-sided over most of length, but barely narrowing at apex, apex truncate (length 0.36, maximum width 0.18, minimum width 0.16), and with scattered pubescence concentrated in the first distal third. Lateral grooves delimiting the median area on T2 clearly defined and reaching the distal edge of T2 (length median area 0.14, length T2 0.14), edges of median area obscured by coarse sculpture, median area broader than long (length 0.14, maximum width 0.22, minimum width 0.12); T2 with scattered pubescence only distally. T3 longer than T2 (0.20, 0.14) and with scattered pubescence throughout. Pubescence on hypopygium dense.

Cocoons. Unknown.

Comments.

The specimens are slender/elongate and cylindrical , the body is distinctively curved ( Fig. 186A ), and the limit between the mesopleuron and the metasternum is truncate throughout.

Male.

Similar in coloration to females.

Etymology.

Peter Marz is a German journalist and husband of DCAP.
