Taxonomic notes on Monoicomyces with descriptions of two new species

Fourteen species of Monoicomyces were included in this study. Two species on beetles were described as new: Monoicomyces ceylonensis, parasitic on Atheta inornata from Sri Lanka, and M. benjaminii parasitic on Atheta sp. from U.S.A. All of these species form a well-defined group, among the known taxa of Monoicomyces, characterized by the almost entirely deep or blackish brown antheridia. Except for M. chosunensis and M. bolitocharae, they were studied on the basis of type or authentic material. New records, observations, and illustrations of the studied species were included. A dichotomous key for separating key for separating the species was provided.
