Abstract

The species of the holarctic genus Pyracmon Holmgren are revised. These are presumably all parasites of soil dwelling larvae of Coleoptera. Pyracmon sepiellum (Holmgren) is a parasite of Macropygon piceus LeConte (Dascillidae) and P. ctenicerae n. sp. is a parasite of Ctenicera destructor (Brown) (Elateridae). Seven species are recognized of which two are described as new, namely bucculentum (Holmgren), fumipenne (Zetterstedt), truncicola Thomson, and heteropus (Thomson), all from Europe, nigrifemur n. sp. from Japan, sepiellum (Holmgren), Holarctic, and ctenicerae n. sp. from western North America. The species are described, keyed, and figured based on characters of the adults. The final instar cephalic structures of larvae of sepiellum and ctenicerae are described and figured, these being the first descriptions representing the genus. Relationships of the genus Pyracmon with other members of the subfamily Campopleginae are discussed.

Résumé

Nous avons effectué une révision du genre holarctique Pyracmon Holmgren, dont les espèces sont, semble-t-il, toutes parasites de larves de coléoptères terricoles. Pyracmon sepillum Holmgren est parasite de Macropygon piceus LeConte (Dascillidae) et P. ctenicerae n. sp. est parasite de Ctenicera destructor Brown (Elateridae). Sept espèces dont deux nouvelles sont reconnues : P. bucculentum Holmgren, P. fumipenne Zetterstedt, P. truncicola Thomson et P. heteropus Thomson, toutes originaires de l'Europe; P. nigrifemur n. sp. du Japon; P. sepiellum Holmgren de la région holarctique; et P. ctenicerae n. sp. de l'ouest de l'Amérique du Nord. Les espèces sont décrites, illustrées et classifiées d'après les caractères des insectes adultes. Les descriptions et illustrations des structures céphaliques du stade final des larves de P. sepiellum et P. ctenicerae représentent les premières études du type pour ce genre. Les relations entre Pyracmon et les autres membres de la sous-famille Campopleginae sont passées en revue.
