Some new North American Collembola

• David L. WRAY (Raleigh N.С.)

Abstract:

The first genus described in this paper (Stachanorema n. gen.) is very near the genus Anurophorus Nicolet. For comparative purposes a description of the latter genus and Anurophorus laricis Nicolet are given. Illustrations are given of both A. laricis Nic. and Stachanorema arnaudi n. sp. in order to point out the similarities and differences between them. The latter form was found occuring with A. laricis Nic. in a collection from Washington State. This new genus and the one following (Stachiomella n. gen.) are dedicated to Dr. Jan Stach who has contributed so very much to the knowledge of this interesting group of insects.                                                                                                                                                                                                                                      STRESZCZENIE. Autor ustanawia dwa nowe rodzaje skoczogonków, a mianowicie Stachanorema n. gen. i Stachiomella n. gen. oraz opisuje następujące nowe gatunki: Stachanorema arnaudi n. sp., Stachiomella oxfordia n. sp. i Entomobrya stachi n. sp. Poza tym, dla porównania, podaje opis Anurophorus larcis Nicolet.
