Cryptopygus Bipunctatus (Collembola: Isotomidae) in North America, and C. Posteroculatus N. Comb.

Abstract

Specimens of Cryptopygus bipunctatus are reported and described from North America (Michigan) for the first time. The species is easily recognized by its lack of color, one pair of ocelli on black eyespots, and one pair of ventral manubrial setae. Michigan and European specimens are very similar. A very similar Polish species, Isotomina posteroculata, is transferred to Cryptopygus
