Thirty valid species and their junior synonymous were investigated. Neotropical species of Epyrinae were also examined in order to find possible misclassified species of Bakeriella. Diagnoses and illustrations of all valid species are provided. Male genitalia of 14 previously described species are first described and illustrated. The lectotypes of Bakeriella flavicornis Kieffer, 1910 and Epyris...

Despite a fairly good number of Miocene insect-bearing deposits available worldwide, the bethylid wasps from this period are yet very poorly known. Here, we describe and figure three new species in subfamilies, early to middle Totolapa (Mexico): Goniozus cotyi sp. nov. (Bethylinae), Bakeriella nanyhelae (Epyrinae), Solepyris electromexicanus (Scleroderminae). The cosmopolitan Förster, 1856 was ...

Melanepyris Kieffer, 1913 was proposed to accommodate a single species of Epyris Westwood, 1832, E. imicola Kieffer, 1913, mainly based on the absence of the posterior propodeal carina. Today, Melanepyris includes only two nominal species. The type-material of these species has been considered lost since their original description. In this study, the single known adult male (holotype) of Melane...
