Abstract
Seven new records and three new species of Stigmatomyces (S. australis, S. baeopteri and S. clasiopellae), a genus of Laboulbeniales associated only with Diptera, are described from New Zealand and New Caledonia. Two new host families for Laboulbeniales are recorded, and a dichotomous key to Stigmatomyces species in New Zealand and New Caledonia is presented.
