Cocoons. White oval cocoons with silk fibers messy/disordered/fluffy. Fluffy cocoons separated, but tightly attached and adhered to the larval cuticle.
The mesopleuron is elongated and rectangle-shaped, the precoxal groove is shallow, the telotarsus on fore leg is twice the length of fourth tarsomere (0.10, 0.05) and with a comb in the claw, the fifth tarsomere proximally is narrow, but it expands distally, the head in dorsal view is rectangular, and the petiole and the median area with the edges clearly distinct.
( Fig. 6 A–K View Figure 6 ). The body coloration is darker than females and the antennal flagellomeres are shorter than females.
Alejandro A. Valerio is a Costa Rican entomologist; as a graduate student at UIUC, IL, USA he worked with Parapanteles and Hypomicrogaster ( Microgastrinae) from ACG. Currently, he works at the Central American Institute of Biological Research and Conservation ( CIBRC), Costa Rica.
Parasitized caterpillars were collected in Costa Rica, ACG, Sector Santa Rosa (Cafetal and Bosque Humedo), during June-July 1990, June 1993, and June 2004, at 280-290 m in dry forest and coffee plantations.
The lifestyle of this parasitoid species is gregarious.
