Synonyms and other taxonomic changes
=Malachius horni (based on A.J. Mayor's pers. comm. to =v= 5/10/10 -- see below)
=Malachius spinipennis
This species is referred to by North American coleopterists as M. horni. However, M. horni and some other names are junior synonyms of M. capillicornis Ab. de Perrin. Perrin described M. capillicornis from Turcménie, but this must have been a mix-up in localities as the type series contains two species, both from southern California. The synonymy has not been formalized yet, but I am about to publish a catalog of Melyridae which will have formal synonymies in a taxonomic changes section at the front of the catalog. (A.J. Mayor)
