Synonyms and other taxonomic changes
This common and widely distributed species has been called "Derobrachus geminatus", but examination of type specimens revealed that the true geminatus refers to a much less common species we have called "Derobrachus forreri" (Santos-Silva, 2007). Rules of nomenclature require that the name geminatus be applied to the less common species (with forreri as a synonym), leaving the common species without a name.
Derobrachus hovorei Santos-Silva is the new name given to this species, which can be distinguished from true D. geminatus (formerly D. forreri) by its more weakly striolate antennae.
