Subgenus Aplocentrus LeConte, 1847

Aplocentrus LeConte, 1847: 385. Type species: Harpalus caenus Say, 1823 designated by Lindroth (1968: 857). Etymology. From the Greek haplos (simple) and centron (spur), alluding to the simple (i.e., not trifid as compared to members of Triplectrus [= Gynandrotarsus ]) apical spur of protibia of the adult (" tibiae anticae calcare terminali simplice ") [masculine].

Haplocentrus Csiki, 1932a: 1077. Unjustified emendation of Aplocentrus LeConte, 1847.

Aplocentroides Ball and Bousquet, 2000: 92. Unnecessary replacement name for Aplocentrus LeConte, 1847. Etymology. From the generic name Aplocentrus [q.v.] and the Greek suffix - oides (resembling, having the form of) [masculine]. Note. Aplocentrus calliops Rafinesque, 1819, the type species and sole species in the genus Aplocentrus Rafinesque, 1819 is "apparently a mythical" species of fish based on a purely imaginative drawing that Audubon prepared as a hoax (Eschmeyer 1998: 1843). Therefore, the name Aplocentrus Rafinesque, 1819 is a nomen nudum and the replacement name, Aplocentroides Ball and Bousquet, 2000, is unnecessary.
