Abstract

It is demonstrated that there is no valid basis on which to sustain the monotypic genus Bathycranium Strobl and concluded that Bathycranium should be recognised as a junior synonym of Syntormon Loew (new status). The species Syntormon bicolorellus Zetterstedt (new combination) falls into a natural grouping of Syntormon species with downcurved facial hairs in females. This species and S. luteicornis Parent are redescribed. Distinctions between Syntormonand Parasyntormon are discussed.
