Species of this subgenus of Cremastocheilus are most often found in the nests of Camponotus.
Identification
This subgenus consists of at least three closely related species; Cremastocheilus planatus, Cremastocheilus puncticollis, and Cremastocheilus beameri. Species are all large; anterior tarsi with 4th an 5th segments dilated; and head with a distinct lateral carina above each eye. Both of these areas contain exocrine glands which probably mediate interactions with ants.
Distribution
Arizona, California, New Mexico, Texas; Mexico.
Habitat
Desert, arid areas.
Biology
Mating of one species, Cremastocheilus beameri is at the entrance to kangaroo rat burrows and other mammal burrows. Cremastocheilus planatus has been found with Camponotus semitestaceus in California and Cremastocheilus puncticollis with Myrmecocystus mexicanus in California.
