Abstract

Pelosoma pecki is described as new from specimens from the Florida Keys (Upper Matacumba Key) and from Mexico (Oaxaca). The genus Genyon Smetana 1978 (type-species Cercyon navicularis Zimmerman 1869, from eastern North America) is placed in synonymy with Tectosternum Balfour-Browne 1958 (type-species T. exstriatum Balfour-Browne 1958, from equatorial Africa). A lectotype is designated for Pelosoma prosternale Sharp 1882, and Pelosoma praecursor Smetana 1978 is placed in synonymy with P. prosternale Sharp 1882.

Omicrus intermedius Smetana and the genus Cycrillum Knisch, with the species C. strigicolle (Sharp), are recorded for the first time from North America.

Additional data on bionomics, geographical distribution, and synonymy of many species are presented.

Résumé

Une espèce nouvelle pour la science, Pelosoma pecki, est décrite à partir d'exemplaires des Keys de la Floride (Upper Matacumba Key) et du Mexique (Oaxaca). Le genre Genyon Smetana 1978 (espèce-type Cercyon navicularis Zimmerman 1869, de l'est de l'Amérique du Nord) est placé en synonymie avec Tectosternum Balfour-Browne 1958 (espèce-type T. exstriatum Balfour-Browne 1958, de l'Afrique équatoriale). Un lectotype est désigné pour Pelosoma prosternale Sharp 1882, et Pelosoma praecursor Smetana 1978 est placé en synonymie avec P. prosternale Sharp 1882.

Omicrus intermedius Smetana et le genre Cycrillum Knisch, avec l'espèce C. strigicolle (Sharp), sont mentionnés pour la première fois en provenance d'Amérique du Nord.

Des données additionnelles sur l'habitat, la répartition géographique et la synonymie de plusieurs espèces sont incluses.
