The phylogenetic relationships among representatives of 64 genera of the cosmopolitan parasitic wasps of the subfamily Doryctinae were investigated based on nuclear 28S ribosomal (r) DNA (~650 bp of the D2\–3 region) and cytochrome c oxidase I (COI) mitochondrial (mt) DNA (603 bp) sequence data. The molecular dating of selected clades and the biogeography of the subfamily were also inferred. The partitioned Bayesian analyses did not recover a monophyletic Doryctinae, though the relationships involved were only weakly supported. Strong evidence was found for rejecting the monophylies of both Doryctes Haliday, 1836 and Spathius Nees, 1818. Our results also support the recognition of the Rhaconotini as a valid tribe. A dispersal\–vicariance analysis showed a strong geographical signal for the taxa included, with molecular dating estimates for the origin of Doryctinae and its subsequent radiation both occurring during the late Paleocene\–early Eocene. The divergence time estimates suggest that diversification in the subfamily could have in part occurred as a result of continental break-up events that took place in the southern hemisphere, though more recent dispersal events account for the current distribution of several widespread taxa.

A comprehensive taxonomic study is presented for the 63 genera and 172 species of braconid wasp subfamily Doryctine\ occurring in Costa Rica. Of these, 12 genera and 119 species are described as new to science. The speciose genus\ Heterospilus\ is excluded from this study. Keys for identification of the genera and species are provided and each genus and species is described and illustrated. Several genera previously describe from South America or other parts of Central America are recorded for the first time from Costa Rica. One new synonymy is proposed: the genus\ Achterbergia\ Marsh is considered a junior synonym of the genus\ Aivalykus\ Nixon (n.syn.). Two new combinations are proposed:\ Achterbergia\ arawak\ Marsh is transferred\ to\ Aivalykus\ (n. comb.);\ Platydoryctesamazonensis\ Barbalho\ and\ Penteado-Dias\ is transferred to the new genus\ Angelica\ (n.comb.). Very little is known about the biology of doryctine wasps,but where host records are available most species appear to be idiobiont ectoparasitoids of wood boring beetle larvae. However, three genera in Costa Rica depart remarkably from this biology: several species of\ Allorhogas\ and\ Labania\ have been reared from leaf and seed galls on various plant, and species of\ Psenobolus\ develop as inquilines in figs. A checklist of the Costa Rican Doryctinae is provided. A Spanish translation of the key to genera is included as an appendix.
