Abstract

A total of about 80 species of Collembola were extracted from 87 qualitative samples mainly from alpine and subalpine sites in the Front Range of Colorado (Boulder, Gilpin, Grand, Clear Creek, and Larimer counties). The following seven new species are described: Friesea pati n.sp., Stachorutes navajellus n.sp., Anurophorus elongatus n.sp., A. senex n.sp., Folsomia variablis n.sp., F. evansi n.sp., and Bourletiella (B.) pisifera n.sp. Characteristic associations of species were found in several habitats, in particular in alpine snow-edge communities (Ceratophysella sp., Isotoma uniens, I. sp.) and alpine dry meadows (dominated by Anurophorus elongatus n.sp.). Compared with the northern parts of the Rocky Mountain Cordillera (Alaska, Washington) there is a remarkable absence of species of the Anurida complex in the Colorado Front Range.
