Fore and middle legs yellow except brown coxae and claws; hind legs yellow except black-brown coxae, brown apex of femora and distal half of tibiae and tarsomeres brown.

Face shape flat or nearly so, with dense fine punctations, interspaces with microsculpture and longitudinal median carina present. Frons punctate. 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, 0.11). Malar suture present. Median area between lateral ocelli slightly depressed. Vertex laterally rounded and dorsally wide.

Mesosoma ( Fig. 72 A–C, E ). Mesosoma dorsoventrally convex. Mesoscutum 1/4 distal with a central dent, 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 flat and on same plane as 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 semicircular/parallel carinae. Transscutal articulation with small and heterogeneous foveae, area just behind transscutal articulation smooth, shiny and depressed centrally. Metanotum with BM wider than PFM (clearly differentiated); MPM circular and bisected by a median longitudinal carina; AFM without setiferous lobes and not as well delineated as PFM; PFM thick and smooth; ATM proximally with semircular/undulate carina and distally smooth. Propodeum without median longitudinal carina, proximal half curved with medium-sized sculpture and distal half relatively polished or with a shallow dent at each side of nucha; 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.

Propleuron with fine punctations throughout and dorsally with a carina. Metasternumflat or nearly so. Contour of mesopleuron straight/angulate or nearly so; precoxal groove smooth, shiny and distinct; epicnemial ridge convex, teardrop-shaped.

Legs ( Fig. 72A ). Ventral margin of fore telotarsus slightly excavated and with a tiny curved seta, fore telotarsus almost same width throughout and longer than fourth tarsomere (0.12, 0.06). Hind coxa with punctation only on ventral surface, dorsal outer depression present. Inner spur of hind tibia longer than outer spur (0.21, 0.15), entire surface of hind tibia with dense strong spines clearly differentiated by color and length. Hind telotarsus as equal in length as fourth tarsomere (0.11, 0.11).

Etymology.

Donald (Don) L. J. Quicke is a braconidologist and hymenopterist with a long-standing interest in many diverse aspects of parasitoid biology and evolution and he is also a book writer. Currently, he is at the Chulalongkorn University, Bangkok, Thailand.

Distribution.

Parasitized caterpillars were collected in Costa Rica, ACG, Sector Del Oro (Sendero Puertas), Sector Pitilla ( Estación Pitilla and Pasmompa ), Sector Rincón Rain Forest ( Estación Caribe, Sendero Albergue Crater, and Vado Río Francia), and Sector Santa Rosa (Cafetal), during October 1993, September 2001, November and December 2006, September 2009, and May, July, and September 2010 at 280 m, 400 m, 415 m, 440 m, 445 m, and 675 m in coffee plantation, intergrade dry-rain and rain forests.

Biology.

The lifestyle of this parasitoid species is gregarious.

Host.

Condica cupienta (Cramer) ( Noctuidae : Amphipyrinae) feeding on Neurolaena lobata and Pluchea carolinensis ( Asteraceae ) and C. funerea (Schaus) ( Noctuidae : Amphipyrinae) (Fig. 4AA) feeding on Neurolaena lobata ( Asteraceae ). Caterpillars were collected in second, third, fourth, and fifth instar.
