Catalogue of Mymaridae in the Neotropical region

A brief review of groups of genera is presented before cataloguing the genera and species instead of after cataloguing them, as was done in Huber et al. (2021). This is to avoid repetition of the genera in each species group catalogued below. The species from Mexico are excluded as these were treated elsewhere (Guzmán-Larralde et al. 2015); those found in Bermuda and the Caribbean islands are included.

Lin et al. (2007) proposed 12 informal groups of genera for the 46 valid genera recognized at the time for Australia. Huber et al. (2021) classified the Afrotropical genera in 11 informal groups of genera. These were intuitive groups that potentially could represent fairly well delimited tribes. However, the subfamilial and tribal classification of Mymaridae using morphological features has still not been resolved, at least not formally. The classification of subfamilies and tribes proposed in Annecke & Doutt (1961), the only world generic treatment, had some useful ideas but ultimately is rejected since it clearly contained polyphyletic family-group taxa. Many new genera have been proposed since then. Schauff (1984) provided the only phylogenetic analysis, based on morphology, of the 22 Holarctic genera recognized at the time but did not classify them formally into tribes and subfamilies. A molecular phylogeny ( Cruaud et al. 2024) gives interesting ideas of relationships among the 20 included genera they sequenced. Only 11 genera were common to both analyses so they are not very comparable but they are generally congruent and match fairly well the groups of genera proposed below.A molecular phylogeny based on most of the valid world genera is nearing completion (K. Dominguez, University of California, Riverside, personal communication). It will be interesting to see how well any proposed groups of genera from her study will correspond with the 11 informal groups below, taking into account that the classification based on molecules will be on a world basis whereas classification proposed below is for the Western Hemisphere only. The only additional group would the Eustochomorpha Girault group of genera, which does not occur in the Western Hemisphere. The somewhat updated, informal grouping of genera given here for the 60 valid genera we recognize occurring in the Neotropical region would also include the genera in the Nearctic region, only two genera ( Eustochus Haliday and Macrocamptoptera Girault ) of which do not occur in the Neotropical region. Those two genera are, respectively, in the Polynema group and Camptoptera group of genera, so they do not affect the groups of genera here. The only significant difference with the proposed groups of Afrotropical genera is the placement of Chrysoctonus , in the Borneomymar Huber group ( Huber et al. 2021) versus the Arescon group (this paper).
