Percina lenticula, a New Percid Fish, with a Redescription of the Subgenus Hadropterus

Abstract

T HE discovery of Percina lenticula, a distinctive new species from the Alabama River basin, brings to 3 the number of species in the subgenus Hadropterus. In addition to describing the new species, it seems desirable here to diagnose and redescribe the subgenus and to review its nomenclatural history. The monotypic genus Hadropterus was erected by Agassiz (1854) when he described H. nigrofasciatus from near Mobile, Alabama. Since that time, Hadropterus has been used variously as a genus or subgenus and has included a fluctuating number of species. The species and subspecies (including valid and nominal forms) which have been assigned to the genus or subgenus Hadropterus are listed in Table 1. Jordan and Gilbert (1883) added Cottogaster aurantiaca Cope to the genus Hadropterus. Jordan and Evermann (1896) included 4 subgenera (Alvordius, Hadropterus, Serraria, and Ericosma) and 12 forms in the genus Hadropterus. Jordan, Evermann, and Clark (1930) regarded Hadropterus as being monotypic. Bailey (1951) directly or inferentially placed 8 generic names under the genus Hadropterus and later synonymized (Bailey, Winn, and
