Resumo
The Neotropical Toechorychus Townes is revised, cladistically defined and diagnosed; a total of 302 specimens from 14 depositories were examined; 40 species are recognized, 35 of which are described as new: T. sp. nov. 1, T. sp. nov. 2, T. sp. nov. 3, T. sp. nov. 4, T. sp. nov. 5, T. sp.nov. 6, T. sp. nov. 7, T. sp. nov. 8, T. sp. nov. 9, T. sp. nov. 10, T. sp. nov. 11, T. sp. nov. 12, T. sp. nov.13, T. sp. nov. 14, T. sp. nov.15, T. sp. nov.16, T. sp. nov.17, T. sp. nov.18, T. sp.nov. 19, T. sp. nov. 20, T. sp. nov. 21, T. sp. nov.22, T. sp. nov. 23, T. sp. nov.24, T. sp. nov. 25, T. sp. nov. 26, T. sp. nov. 27, T. sp. nov. 28, T. sp. nov. 29, T. sp. nov.30, T. sp. nov.31, T.sp. nov. 32, T. sp. nov. 33, T. sp. nov.34, T. sp. nov. 35. The other valid species are: T. abactus(Cresson), T. albimaculatus (Taschenberg), T. brevicaudis (Szépligeti), T. cassunungae (Brauns), T. stramineus (Taschenberg). The genus can be recognized by epicnemial carina usually not reaching more than 0.3 of distance to subtegular ridge; apical V-shaped sulcus at dorsal valve of ovipositor, anteriorly to apical teeth of ventral valve; subapical compression at ovipositor anteriorly to apical teeth of ventral valve; ovipositor sheath about 0.1 as long as hind tibia; and dorsal margin of pronotum strongly swollen. A key and descriptions are provided to all valid species, and cladistic analysis is provided, as well as illustrations and distributions. Published host records were compiled, and three new records are provided, as follows: T. albimaculatus is a parasitoid of Mischocyttarusdrewseni (Saussure) (Vespidae, Polistinae) new record; T. stramineus is a parasitoid of M. basimacula (Cameron) new record; and T.sp. nov. 25 is a parasitoid of M. collarellus Richards new record. A Neotype is designated for T. cassunungae. The genus is probably more closely related to Lymeon Förster and Acerastes Cushman
