New Records of Braconidae (Hymenoptera) Subfamilies and Genera from Mexico and the State of Yucatan

First records are reported for subfamilies and genera of Braconidae in Mexico and the state of Yucatan based on material deposited in CER-UADY. First records were made for the Sigalphinae subfamily in Mexico, and for the Cenocoeliinae, Ichneutinae and Mendesellinae subfamilies in Yucatan. In total there are 27 reported New World subfamilies in Mexico, and 25 in Yucatan, based on the classification of Wharton et al., 1997. A total of 114 new genera records were made, 48 of them for Mexico and 66 for Yucatan, bringing the list of total known genera in Mexico to 277, and that for Yucatan to 190. The new records demonstrate that the Braconidae fauna of Yucatan is mixed in origin. Of the examined genera, 68.4% were represented in only one vegetation community, leading to a revised distribution hypothesis for the Yucatan Peninsula. Given the results, Yucatan has the highest Braconidae genera richness in Mexico.
