Abstract
Potamocloeon edentatum sp. n. is described based on all stages of both sexes associated by rearing from Usambara Mountains in Tanzania. Some key generic characters, i.e. mode of gonostyli development, genital musculature, patella-tibial suture of winged stages and texture of subimaginal tarsi, are described for Potamocloeon Gillies 1990 (= Maliqua Lugo-Ortiz & McCafferty 1997) for the first time.
