A 2-cell embedding of a graph G into a closed (orientable or nonorientable) surface is called regular if its automorphism group acts regularly on the flags – mutually incident vertex–edge–face triples. In this paper, we classify the regular embeddings of complete bipartite graphs Kn,ninto nonorientable surfaces. Such a regular embedding of Kn,nexists only when n is of the form [Formula: see text] where the piare primes congruent to ±1 mod 8. In this case, up to isomorphism the number of those regular embeddings of Kn,nis 2k.
