Revision of the North American species of the genus Entomacis (Hymenoptera: Diapriidae)

  • Matthew J. Yoder (a1)


The species of the genus Entomacis Foerster in North America north of Mexico are revised. Nineteen species (12 new), including 8 species of the Holarctic-wide perplexa species group, are keyed, described, and figured. These taxa are E. ambigua (Brues), E. apopkaensissp. nov., E. arcticasp. nov., E. cellariasp. nov., E. cepasp. nov., E. eorariasp. nov., E. floridana (Ashmead), E. grandiclavasp. nov., E. longii (Ashmead), E. mellipetiola (Ashmead), E. parambiguasp. nov., and perplexa group members E. californica (Ashmead), E. microbipunctatasp. nov., E. notioxerasp. nov., E. oulasp. nov., E. parvasp. nov., E. perplexa (Haliday), E. sapratasp. nov., and E. subemarginata (Ashmead). Hemilexodes canadensis (Harrington) is synonymized under Entomacis mellipetiola (Ashmead) (syn. nov.). The status of Entomacis latipennis (Ashmead), E. filiformis (Ashmead), and Hemilexis jessei Mann is reviewed. New character complexes, particularly chaetotaxy, are emphasized for Diapriidae species taxonomy.

La révision des espèces du genre Entomacis Foerster d'Amérique du Nord au nord du Mexique contient des clés d'identification, ainsi que les descriptions et les illustrations de dix-neuf espèces (dont 12 nouvelles), y compris les 8 espèces du groupe d'espèces de perplexa dont la répartition s'étend à toute la région holarctique. Ces taxons sont E. ambigua (Brues), E. apopkaensissp. nov., E. arcticasp. nov., E. cellariasp. nov., E. cepasp. nov., E. eorariasp. nov., E. floridana (Ashmead), E. grandiclavasp. nov., E. longii (Ashmead), E. mellipetiola (Ashmead), E. parambiguasp. nov., ainsi que les membres du groupe de perplexa, E. californica (Ashmead), E. microbipunctatasp. nov., E. notioxerasp. nov., E. oulasp. nov., E. parvasp. nov., E. perplexa (Haliday), E. sapratasp. nov. et E. subemarginata (Ashmead). Hemilexodes canadensis (Harrington) devient un synonyme d'Entomacis mellipetiola (Ashmead) (syn. nov.). Le statut d'Entomacis latipennis (Ashmead), celui d'E. filiformis (Ashmead) et celui d'Hemilexis jessei Mann sont revus. De nouveaux complexes de caractères, particulièrement de chétotaxie, sont mis en valeur dans la taxonomie des espèces de diapriidés.
