Type species:  Harpalus dilatatusDejean, 1829 designated by Desmarest (1851: 126). Etymology. From the Greek dis(twice) and cheiros(hand), probably alluding to the trifid (mistakenly thought to be double) apical spur of the protibia (" tibiae anticae spina apicali duplici") of the adult [masculine].  Diplocheirus Menetries, 1843 [29 July]: 62. Type species:  Harpalus dilatatusDejean, 1829 by monotypy. Etymology. From the Greek prefix diplo- (double) and cheiros(hand) [masculine]. Note. With the evidence available, this name should have precedence. However, the name is not in prevailing usage and for that reason it is not retained here as valid (see  Principle of priorityin the "Nomenclature"section).  DichirusAgassiz, 1846: 122.
