Teratocephalus terrestris
(Butschli, 1873) de Man, 1876
Photo Gallery- Long's Peak, Colorado

     This species is immediately distinguished by its small size, coarsely striated cuticle and long filiform tail with its arcuate terminus.  The head with its cutinous framework is an especially prominent feature.
     This is one of the most widely distributed species in the western mountains but occurs only in small numbers.  Two specimens appeared in this collection.
