Abstract

The Nearctic species of the genus Trichacis are revised. Nine out of 15 species recognized are new to science: T. alticola (New Mexico, Colorado), T. bison (Ontario, Florida, Louisiana, Illinois, Texas), T. celticola (Mississippi, Ontario, Louisiana, Texas), T. dracula (Illinois), T. elongata (Missouri), T. huberi (California), T. mandibulata (Illinois), T. pyramidalis (Ontario), and T. striata (Florida). Six previously described Nearctic species are redescribed, viz. T. arizonensis (Ashmead), T. cornicola (Ashmead), T. cornuta Fouts, T. rufipes Ashmead, T. texana Fouts, and T. virginiensis Ashmead. The males of T. arizonensis, T. texana, and T. virginiensis are described for the first time. A generic diagnosis of Trichacis and keys to Nearctic species are given. The higher classification, bionomics, world distribution, and character states of Trichacis species are discussed.

Résumé

La taxonomie du genre Trichacis de la région néarctique est revue. Des 15 espèces incluses dans le genre, nous décrivons 9 nouvelles espèces : T. alticola (Nouveau Mexique, Colorado), T. bison (Ontario, Floride, Louisiane, Illinois, Texas), T. celticola (Mississippi, Ontario, Louisiane, Texas), T. dracula (Illinois), T. elongata (Missouri), T. huberi (Californie), T. mandibulata (Illinois), T. pyramidalis (Ontario), et T. striata (Floride). Les six autres espèces, viz. T. arizonensis (Ashmead), T. cornicola (Ashmead), T. cornuta Fouts, T. rufipes Ashmead, T. texana Fouts, et T. virginiensis Ashmead sont redécrites, et les mâles de T. arizonensis, T. texana et T. virginiensis sont décrits pour la première fois. Nous pourvoyons une diagnose du genre et un tableau de détermination des espèces néarctiques. La classification supraspécifique, la biologie, la répartition géographique mondiale et la polarité de transformation des caractères des espèces du genre Trichacis sont discutées.
