There are other useful characters to distinguish the genus (e.g. see Mason 1981, Whitfield 1997); but the four detailed above serve well to separate the Apanteles sensu stricto LIMKI 3 cost described here from Choeras (Mequitazine web character a), from Dolichogenidea (character b), from Exoryza (character b), from Iconella (character d), and from Illidops (character c). A total of 23 Apanteles species were previously known from Mesoamerica (Yu et al. 2012, Smith et al. 2013). After studying the type material for these taxa, 19 are retained in Apanteles sensu stricto and treated in this paper, while four species are transferred to other Microgastrinae genera. The status of the Mesoamerican species Apanteles albinervis (Cameron 1904) is revised, and one European species that is involved in a secondary homonym with the former is transferred to Iconella. All of these nomenclatorial acts are detailed below. When the 186 new species from ACG described in this paper are included, the Apanteles fauna of Mesoamerica comprises 205 species, or about 10 times more species than previously known from that region. There was only one described species recorded from Costa Rica, 19 from Mesoamerica, 86 from the Neotropical region, and 1010 worldwide (Yu et al. 2012). This study emphasizes how much is still unknown about the diversity of parasitoid wasps in general, and Microgastrinae in particular (e.g., Rodriguez et al. 2012). It is unlikely that ACG contains 20 of the species of a global genus as widely distributed and diverse as Apanteles. A more logical explanation is that, whenever other regions are as comprehensively studied, many more undescribed species of Apanteles will be revealed. Even for ACG we are far from completing the inventory of Apanteles. We are aware of another 19 species (which would represent an additional 10 of increase for ACG), which we had to exclude because the available specimens were in poor condition and/or were only represented by males (in most cases Microgastrinae male specimens cannot be taxonomically dealt with, except through their DNA barcodes, or by inference through membership in a presumed sib group containing females, or reared from only one caterpillar). Those species are not described in this paper, although some of their interim names are provided here, for future reference, Apanteles Janzen11, Apanteles Janzen16, Apanteles Janzen34, Apanteles Rodriguez50, Apanteles Rodriguez74, Apanteles Rodriguez75, Apanteles Rodriguez79, Apanteles Rodriguez109, Apanteles Rodriguez121, Apanteles Rodriguez127, Apan-Jose L.
