OMALONOMUS RELICTUS, AN UNUSUAL NEW GENUS AND NEW SPECIES (COLEOPTERA: STAPHYLINIDAE, OMALHNAE) OF BLIND ROVE BEETLE; A PREGLACIAL (TERTIARY?) RELICT IN THE CYPRESS HILLS, ALBERTA–SASKATCHEWAN, CANADA

Abstract

Omalonomus relictus, a highly modified new genus and new species of soil-dwelling rove beetle, is described from the Cypress Hills of Alberta and Saskatchewan. The structural peculiarities associated with its subterranean habitat are discussed and illustrated. Moore and Legner’s (1974) key to the genera of North American Omaliinae is modified to assist in the identification of adults of the genus. The occurrence of this blind, slightly pigmented, flightless beetle in the soil of the Cypress Hills supports the hypothesis that at least part of this area was unglaciated and served as a refugium during late Pleistocene glacial advances.

Résumé

Les auteurs donnent une description de Omalonomus relictus, représentant un nouveau genre et une nouvelle espèce de staphylin hypogé, en provenance des Cypress Hills de l’Alberta et de la Saskatchewan. On discute et illustre les particularités structurales reliées à son mode de vie souterrain. Les auteurs présentent une modification au tableau de détermination de Moore et Legner (1974) pour permettre la détermination des adultes de ce genre. La présence de ce coléoptère aveugle, légèrement pigmenté, et sans ailes supporte l’hypothèse selon laquelle au moins une partie de cette région était exempte de glace et servait de refuge lors des avances glaciaires de la fin du Pleistocene.
