Abstract : In the present paper we construct a bijection that relates a set of unicellular bicolored maps to a set of couples of ordered bicolored trees and partial permutations. This bijection allows us to derive an elegant formula for the enumeration of unicellular bicolored maps , an analogue of the well-known Harer-Zagier result for unicolored one-face maps.
