Abstract

Ptomaphagus inyoensis is described from Poleta Cave, Inyo County, California. Its reduced, but present, eyes and reduced flight wings suggest that it is a deep soil species. The spermatheca shape and other characters suggest that it is in a group with Ptomaphagus fisus Horn, a species widespread in animal nests and burrows in the southwest, Ptomaphagus cocytus Peck, a cave-restricted species from the Grand Canyon of Arizona, and Ptomaphagus manzano Peck, a montane litter species from New Mexico. A comparative morphological analysis of the group is presented.

Résumé

On trouvera ici la description de Ptomaphagus inyoensis trouvé à Poleta Cave, Co. d’Inyo, en Californie. Ses yeux minuscules (mais présents) et ses ailes de vol réduites indiquent qu’il s’agit probablement d’une espèce qui vit en profondeur dans le sol. La forme de la spermathèque, de même que d’autres caractéristiques, tendent à indiquer que l’espèce fait partie du même groupe que Ptomaphagus fisus Horn, une espèce répandue dans les nids et terriers d’animaux dans le sud-ouest, Ptomaphagus cocytus Peck, une espèce confinée aux cavernes du Grand Canyon en Arizona, et Ptomaphagus manzano Peck, une espèce de litière des montagnes du Nouveau-Mexique. Une analyse morphologique comparative des espèces du groupe est présentée.
