A new noctuid species, Apamea yunnana sp. n. is described from the Yun
nan Province, S China. The moth is superficially similar to A. ferrago
(Eversmann) and to the recently described A. nekrasovi Mikkola, Varga
& Guylai but differs from these in the details of the forewing patter
n and more so in the structure of genitalia. The adult and the male ge
nitalia of the new species are illustrated.
