  • Troxochrus cirrifrons (O. Pickard-Cambridge, 1871) is a junior synonym of Troxochrus scabriculus (Westring, 1851). Moreover, Troxochrus scabriculus is a species with dimorphic males, the nominate form is referred to as T. scabriculus forma scabriculus, and the second morph as T. scabriculus forma cirrifrons. No significant differences are present in the male palps or any sexual characters of these two forms. Likewise, the accompanying females of different populations exhibit no significant differences in general appearance or genitalia. We provide data on the taxonomic history, national checklists, habitat and distribution, as well as phenology to support the synonymy and to verify male dimorphism in Troxochrus scabriculus.
