A REVISION OF THE NORTH AMERICAN OMALIINAE (COLEOPTERA: STAPHYLINIDAE): 2. THE TRIBE CORYPHIINI
Published online by Cambridge University Press: 31 May 2012
Abstract
The tribe Coryphiini Hatch is redefined to include six genera and 18 species from North America. Two new genera are described: Gnathoryphium (type-species G. mandibulare n. sp.) and Holoboreaphilus (type-species Boreaphilus nordenskioeldi Maklin). Seven new species are described: Coryphium nigrum from the northeastern United States and Subhaida californica, S. aptera, S. monticola, S. utahensis, S. sinuata, and Gnathoryphium mandibulare from western North America. The genus Occiephelinus Hatch from western North America and Planeboreaphilus Shibata from Japan are considered junior synonyms of Coryphium Stephens. The western North American species formerly placed in Ephelinus Cockerell are transferred to the genus Coryphium. Pseudohaida ingrata Hatch is transferred to the genus Subhaida Hatch. Boreaphilus americanus Notman is placed in synonymy with B. henningianus C.R. Sahlberg.All genera and species are described. Habitus drawings, and line drawings of the antenna, labrum, maxilla, mandible, mentum, and labium are presented for at least one species of each genus. The aedeagus is illustrated for all the species except two that are known only from females.Of the species treated, three are Holarctic in distribution, four are restricted to eastern North America, and 11 are endemic to the mountainous areas of western North America.All available biological information for each species is included and a key is presented to aid in the identification of all the genera and species of the tribe in North America.
