Paratypes. • 26 (4♀, 5♂) (14♀, 3♂); EC-1932, YY-A077; same data as for holotype; ( PUCE) .

Diagnosis.

Distal half of propodeum with a mix of coarse sculpture and rugae ( Figs 84F , 85C ), precoxal groove deep ( Figs 84H , 85D ), on pronotum central area and dorsal furrow smooth, but ventral furrow with short parallel carinae ( Figs 84C , 85D ), anterior furrow of metanotum without setiferous lobes ( Figs 84F , 85C ), petiole on T1 parallel-sided in proximal half, then narrowing ( Figs 84G , 85F ), edges of median area on T2 obscured by weak longitudinal stripes ( Figs 84G , 85F ), dorsal outer depression on hind coxa present ( Figs 84A , 85A, E ), and fore wing with r vein curved, outer side of junction of r and 2RS veins forming a distinct stub ( Figs 84J , 85G ).

Coloration

( Fig. 84 A–K ). General body coloration polished black except scape with brown tints; all antennal flagellomeres brown in both sides; labrum, mandible and pedicel yellow-brown; glossa, maxillary and labial palps, and tegulae yellow. Eyes and ocelli silver. Fore and middle legs yellow except brown claws and tarsomeres (yellow coloration intensifying from proximal to distal); hind legs yellow except black coxae with yellow apex, a tiny brown dot at the apex of femora, tibiae with apex brown, and tarsomeres brown, although telotarsus with proximal yellow ring. Petiole on T1 black and sublateral areas yellow; T2 with median and adjacent areas (with contours well-defined) brown-black, and lateral ends yellow; T3 with an extended brown area which proximally coincides with width of median and adjacent areas on T2, and proximal corners of lateral ends yellow; T4 and beyond black; distally each tergum with a narrow yellow band. In lateral view, T1-2 completely yellow; T3 yellow, but dorsally brown; T4 and beyond completely black. S1-3 yellow; S4 proximal half yellow, distal half brown; penultimate sternum and hypopygium completely brown.

Description.

Head ( Fig. 84 A–C ). Head rhomboid with pubescence long and dense. Proximal three antennal flagellomeres longer than wide (0.28:0.08, 0.28:0.08, 0.28:0.08), distal antennal flagellomere longer than penultimate (0.14:0.07, 0.12:0.07), antenna longer than body (3.98, 3.68); antennal scrobes-frons shallow. Distal half of face dented only laterally, with dense fine punctations, interspaces smooth and longitudinal median carina present. Frons smooth. Temple wide, punctate and interspaces clearly smooth. Inner margin of eyes diverging slightly at antennal sockets; in lateral view, eye anteriorly convex and posteriorly straight. POL shorter than OOL (0.12, 0.15). Malar suture present. Median area between lateral ocelli slightly depressed. Vertex laterally rounded and dorsally wide.

Mesosoma ( Fig. 84A, D–F, H ) Mesosoma dorsoventrally convex. Mesoscutum with narrow grooves/dents taking the place of notauli, punctation distinct throughout, interspaces wavy/lacunose. Scutellum shield-shaped, 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 completely concealed; BS only very partially overlapping the MPM; ATS demilune entirely covered by parallel carinae; dorsal ATS groove with carinae only proximally. 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 oval/circular with a short proximal carina; AFM without setiferous lobes and not as well delineated as PFM; PFM thick, smooth and with a proximal flat flange; ATM proximally with semircular/undulate carina and distally smooth. Propodeum without median longitudinal carina, proximal half weakly curved with medium-sized sculpture and distal half with a mix of coarse sculpture and rugae; distal edge of propodeum with a flange at each side and without stubs; propodeal spiracle without distal carina; nucha surrounded by very short radiating carinae. Pronotum with a distinct dorsal furrow, dorsally with a well-defined smooth band; central area of pronotum and dorsal furrow smooth, but ventral furrow with short parallel carinae. Propleuron finely sculptured only ventrally and dorsally without a carina. Metasternum flat or nearly so. Contour of mesopleuron straight/angulate or nearly so; precoxal groove deep, smooth and shiny; epicnemial ridge widen.

Legs. Ventral margin of fore telotarsus entire without seta, fore telotarsus proximally narrow and distally wide, and longer than fourth tarsomere (0.11, 0.09). Hind coxa with medium-size punctate throughout, and dorsal outer depression present. Inner spur of hind tibia longer than outer spur (0.31, 0.24), entire surface of hind tibia with dense strong spines clearly differentiated by color and length. Hind telotarsus as equal in length as fourth tarsomere (0.16, 0.16).

Wings ( Fig. 84J, K ). Fore wing with r vein slightly curved; 2RS vein straight; r and 2RS veins forming a weak, even curve at their junction and outer side of junction forming a distinct 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; veins 2CUa and 2CUb completely spectral; vein 2 cu-a present as spectral vein, sometimes difficult to see; 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 very narrow, subdistally and subproximally straightened, and setae present only proximally.

Metasoma ( Fig. 84A, G, I ). Metasoma laterally compressed. Petiole on T1 finely sculptured throughout, parallel-sided in proximal half and then narrowing (length 0.41, maximum width 0.22, minimum width 0.12), 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 0.21, length T2 0.21), edges of median area obscured by weak longitudinal stripes, median area broader than long (length 0.21, maximum width 0.27, minimum width 0.12); T2 with scattered pubescence only distally. T3 longer than T2 (0.29, 0.21) and with scattered pubescence only distally. Pubescence on hypopygium dense.

Cocoons. Unknown.

Comments.

The area replacing the notauli with a depression.

Male

( Fig. 85 A–H ). The body coloration is darker than females. The males are stouter than females.

Etymology.

Fernando (Fer) Fernández is a Colombian entomologist; his work is focused on taxonomy and systematics of Hymenoptera , mainly Formicidae . He is a professor at the Universidad Nacional de Colombia, Bogotá, Colombia.

Distribution.

Biology.

The lifestyle of this parasitoid species is gregarious.

Host.

Memphis nr. lorna (Druce) ( Nymphalidae : Charaxinae) feeding on Nectandra sp. ( Lauraceae ). Caterpillar instar was not reported.
