Notes on the genera Exasticolus van Achterberg (Homolobinae) and Orgilus Haliday (Orgilinae)(Hymenoptera: Braconidae) with the description of 3 new species of French Guiana

<p>Among the collected material from the Kaw Montains, French Guiana, a new species of the genus Exasticolus van Achterberg, 1979 (Hymenoptera: Braconidae: Homolobinae: E. thirionae spec. nov.) and two new species of the genus Orgilus Haliday, 1833 (Hymenoptera: Braconidae: Orgilinae: O. podus spec. nov. and O. quadricolor spec. nov.) were discovered. Exasticolus thirionae spec. nov. differs from the other three known species by the reduced setosity of the fore wings. E. fuscicornis (Cameron, 1887) is for the first time reported from Belize, French Guiana, Guatemala and Venezuela, and E. nigriceps (Enderlein, 1920) from Costa Rica. The morphological variation in the genus Orgilus in the Neotropical region is illustrated by the description of the two new species from French Guiana. Podorgilus brevitarsus van Achterberg, 1994 (Orgilinae) is reported for the first time from Costa Rica. Stantonia pallida (Ashmead, 1894) is a new combination</p>
