Groups. Those 30 species are left out of groups, and categorized as “unassigned”. Six groups each have nine or more species, jointly representing half of all described Mesoamerican species. The largest are the leucostigmus group (39 species parasitizing Hesperiidae) and the adelinamoralesae group (19 species attacking Elachistidae), both with many more Mesoamerican species awaiting description. A total of 15 species-groups (47 ) are represented by two species. This situation is mainly due to the fact that only the ACG fauna has been comprehensively studied. When the remainder of the Mesoamerican Apanteles fauna is revised, many of these groups are likely to have more species associated. We have seen in collections numerous undescribed species from the Neotropics other than ACG, species that fall into some of the new groups erected here (to encourage further study in the future we have noted those cases in the taxonomy treatment of species below). Most groups (79 ) are strongly supported by at least two of three sets of independent data: molecular (DNA barcodes), biology (host), and morphology (Table 2), and their component species can be clearly recognized and delimited. Others are defined mainly by shared morphological characters. In one case (A. joserasi), the group could only be defined by a unique combination of hosts and barcoding characters (see couplet 29 of the key to species-groups). Some groups partially overlap with others, e.g., the adrianachavarriae, javierobandoi, and joserasi groups, and future studies may reveal that they should be merged. However, without study of the whole Mesoamerican (or even Neotropical) fauna, we preferred to take a conservative approach in accommodating the perceived differences.Review of Apanteles sensu stricto (Hymenoptera, Braconidae, Microgastrinae)…Table 2.
