The structures of Ichneumonidae communities in a mangrove area and two nearby locations with different vegetation types are described. The study area is located within the limits of the Nearctic and Neotropical regions at the southern of the State of Tamaulipas, Mexico. Samples were collected with a Malaise trap at each site over a one-year period. The potential species richness was determined using the Clench model. The diversity was determined by Simpson and Shannon-Wiener indexes, and the possible differences among the communities at different sites were established using PERMANOVA multivariate analysis. The relative degrees of influence of the space, time and biogeographic affinity variables on the community structures of these wasps were determined using multiple correspondence analysis. The data showed that the mangrove area, has the greatest potential species richness. There were significant differences among the three communities of ichneumonids. The community structures depend primarily on the biogeographical preferences of each species and secondarily on climate conditions throughout the year, whereas the structures were almost independent of vegetation. Four species obtained in this study are new records for Mexico, and five in the State of Tamaulipas.
