Three new species of the genus Trichocera are described: T.(T.) implicata n.sp., T.(T.) mendli n.sp., both from northern Sweden and the western Alps, and T.(M.) candida n.sp. from the western Alps. The descriptions are based on males only. The material comes mainly from light-trap collections and it is difficult to assign the females to the species described. Whether T. implicata and T. mendli really represent a boreo-alpine element is uncertain as practically no collections of trichocerids from the mountainous parts of Central Europe exist.
