The subject of this paper is the class of idempotent-connected quasi-adequate semigroups which is a class that contains all unit orthodox semigroups in the range of abundant semigroups. The main result is a structure theorem that characterizes these semigroups as semidirect products of a band with identity and a cancellative monoid.
