Head ( Fig. 105A, B, E View Figure 105 ). Head rounded with pubescence short and dense. Proximal three antennal flagellomeres longer than wide (0.19:0.07, 0.19:0.07, 0.19:0.07), distal antennal flagellomere longer than penultimate (0.11:0.05, 0.09:0.05), antenna longer than body (2.63, 2.32); antennal scrobes-frons shallow. Face with dense fine punctations, interspaces with microsculpture, distal half dented only laterally and longitudinal median carina present. Frons smooth. Temple wide, punctate 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 (0.09, 0.12). Malar suture present. Median area between lateral ocelli slightly depressed. Vertex laterally rounded and dorsally wide.

Mesosoma ( Fig. 105 A–C, E View Figure 105 ). Mesosoma dorsoventrally convex. Mesoscutum proximally convex and distally flat, punctation distinct proximally with polished area distally, interspaces wavy/lacunose. Scutellum triangular, apex sloped and fused with BS, scutellar punctation scattered throughout, in profile scutellum convex and slightly higher than mesoscutum, phragma of the scutellum partially exposed; BS only very partially overlapping the MPM; ATS demilune with short stubs delineating the area; dorsal ATS groove with carinae only proximally. Transscutal articulation with small and homogeneous foveae, area just behind transscutal articulation smooth, shiny and nearly at the same level as mesoscutum (flat). Metanotum with BM wider than PFM (clearly differentiated); MPM circular without median longitudinal carina; AFM with a small lobe and not as well delineated as PFM; PFM thick and smooth; ATM proximally with semircular/undulate carina and distally smooth. Propodeum medially rhomboid-shaped with rugae, proximal half curved with fine sculpture and distal half relatively polished; 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 smooth, but both dorsal and ventral furrows with short parallel carinae. Propleuron with a mix of rugae and fine punctation, dorsally with a carina. Metasternum flat or nearly so. Contour of mesopleuron straight/angulate or nearly so; precoxal groove deep with faintly transverse lineate sculpture; epicnemial ridge convex, teardrop-shaped.

Legs. Ventral margin of fore telotarsus entire without seta, fore telotarsus almost same width throughout and longer than fourth tarsomere (0.10, 0.07). Hind coxa with punctation only on ventral surface and dorsal outer depression present. Inner spur of hind tibia longer than outer spur (0.26, 0.19), entire surface of hind tibia with dense strong spines clearly differentiated by color and length. Hind telotarsus shorter than fourth tarsomere (0.10, 0.13).

Wings ( Fig. 105I, J View Figure 105 ). 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 slight 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 a small smooth area; vein 2CUa absent and vein 2CUb spectral; vein 2 cu-a absent; vein 2-1A proximally tubular, distally spectral, although sometimes difficult to see; tubular vein 1 cu-a curved, incomplete/broken and not reaching the edge of 1-1A vein.

Metasoma ( Fig. 105A, D, F–H View Figure 105 ). Metasoma laterally compressed. Petiole on T1 finely sculptured only distally, virtually parallel-sided over most of length, but narrowing over distal 1/3 (length 0.33, maximum width 0.16, minimum width 0.08), and with scattered pubescence concentrated in the first distal third. Lateral grooves delimiting the median area on T2 distally losing definition (length median area 0.11, length T2 0.15), edges of median area polished and lateral grooves deep, median area broader than long (length 0.11, maximum width 0.16, minimum width 0.08); T2 with scattered pubescence only distally. T3 longer than T2 (0.20, 0.15) and with scattered pubescence throughout. Pubescence on hypopygium scattered.

Cocoons ( Fig. 4T View Figure 4 ). White or brown oval cocoons with silk fibers evenly smooth. Masses of separate cocoons adhered among the setae of caterpillar.

Male

( Fig. 106 A–K View Figure 106 ). Similar in coloration to female. The mesosoma is slightly stouter than female.

Etymology.

Ian David Gauld (25 May 1947 - 12 January 2009) is a well-known British entomologist who dedicated his entire career to the evolutionary biology of Ichneumonids (Anomaloniae, Labeninae, Ophioninae, and Pimplinae). He spent the last two decades of his life focusing upon the Costa Rican fauna.

Distribution.

Parasitized caterpillars were collected in Costa Rica, ACG, Sector Brasilia (Moga) and Sector San Cristóbal ( Río Areno, Río Blanco Abajo, Puente Palma, Sendero Corredor, Sendero Huerta, and Vado Río Cucaracho), during June 2000, March 2001, February 2002 and 2005, January 2004, May, October-November 2006, December 2007, January 2009, and March 2011 at 460 m, 500 m, 620 m, and 640 m in rain forest.

Biology.

The lifestyle of this parasitoid species is gregarious.

Host.

Zanola verago Cramer ( Apatelodidae ) ( Fig. 4T View Figure 4 ) feeding on Iresine diffusa ( Amaranthaceae ), Philodendron sp. ( Araceae ), Psychotria berteriana , Hamelia patens and Spermacoce ocymifolia ( Rubiaceae ), Inga oerstediana and I. samanensis ( Fabaceae ), Solanum circinatum ( Solanaceae ). Caterpillars were collected in third, fourth, and fifth instar.
