Inner spur of hind tibia longer than outer spur (0.20, 0.17), entire surface hind tibia with dense strong spines clearly differentiated by color and length. Hind telotarsus longer than fourth tarsomere (0.15, 0.11). <b>Wings</b> (Fig. 25M, N). Fore wing with r vein slightly curved; 2RS vein straight; r and 2RS veins forming an angle 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 microtrichiae virtually throughout; veins 2CUa and 2CUb completely spectral; vein 2 cu-a absent; vein 2-1A proximally tubular and distally spectral, although sometimes difficult to see; tubular vein 1 cu-a curved, incomplete/broken, and not reaching the edge of 1-1A vein. Hind wing with vannal lobe narrow, subdistally evenly convex, subproximally straightened, and setae evenly scattered in the margin. <b>Metasoma</b> (Fig. 25A, H–J, K). Metasoma laterally compressed. Petiole on T1 finely sculptured on distal half, evenly narrowing distally and apex truncate (length 0.32, maximum width 0.18, minimum width 0.14), petiole with scattered pubescence and 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 0.18, length T2 0.18), edges of median area obscured by weak longitudinal stripes, median area broader than long (length 0.18, maximum width 0.20, minimum width 0.10); T2 with scarce pubescence throughout. T3 longer than T2 (0.20, 0.18), T3 with scattered pubescence throughout. Pubescence on hypopygium dense. <b>Cocoons.</b> White oval cocoons with silk fibers messy/disordered/fluffy. Cocoons separate and individually adhered to back of larval cuticle. Male (Fig. 26 A–L). Males tends to be thinner and darker than females. Etymology. Barnard (Barney) D. Burks (November 12, 1909-December 15, 1990) was a well-known American entomologist (especially active with Chalcidoidea) who studied (B.A., M.A., and Ph.D.) at UIUC, IL, USA. Distribution. The parasitized caterpillars were collected in Costa Rica, ACG; Sector Pitilla (Casa Roberto) and Sector Santa Rosa (Bosque Humedo), during November 1982, October 1995, and August 2004 at 290 m and 520 m in dry forest and rain forest. Biology. The lifestyle of this parasitoid species is gregarious. Host. <i>Smicropus intercepta</i> Walker (Geometridae, Sterrhinae) feeding on <i>Mascagnia sinemariensis</i> and <i>Tetrapterys discolor</i> (Malpighiaceae). Caterpillars were collected in third and fifth instars.
