Abstract
The species of Entomacis Foerster of North America north of Mexico are revised. Eleven species (seven new) and one Holarctic species group, the perplexa group, with one previously described species and eight new morphotypes, are keyed, (re)described, and figured. These taxa are E. ambigua (Brues), E. apopkaensis sp. nov., E. arctica sp. nov., E. cellaria sp. nov., E. cepa sp. nov., E. eoraria sp. nov., E. floridana (Ashmead), E. grandiclava sp. nov., E. longii (Ashmead), E. mellipetiola (Ashmead), E. parambigua sp. nov., E. californica (Ashmead) and the perplexa group morphotypes Co, Cy, M, N, O, Pac, Par, and S. Hemilexodes canadensis (Harrington) is found to be a junior synonym of Entomacis mellipetiola (Ashmead) (new synonymy). The status of Entomacis latipennis (Ashmead), Entomacis filiformis (Ashmead), and Hemilexis jessei Mann are reviewed. New character complexes, particularly chaetotaxy, are emphasized for diapriid species taxonomy. A preliminary phylogenetic analysis of Entomacis of worldwide scope, incorporating 50 informative morphological characters and 40 taxa is presented. Twenty-two additional potentially informative characters are briefly discussed. The monophyly of Entomacis Foerster is corroborated, based primarily on the presence of the matte spot, a unique thoracic character of unknown function. A major division between general morphotypes is recovered based primarily on setal and sensillar characters. Several internal clades are hypothesized and discussed.
