Snelling and Snelling (2007) - As Creighton (1950) had pointed out, the authorship of this species has been confused. Wheeler (1908) recorded two male specimens from an unspecified locality in Texas as Eciton (Acamatus) spoliator Forel, 1899, a species originally described from Costa Rica. He provided a translation of Forel's species and a figure that was clearly based on one of the Texas males. Wheeler further noted that the specimens bore an unpublished Cresson name, Acamatus fuscipennis. M. R. Smith (1942) correctly recognized that the Texas specimens were not the same as Forel's species and redescribed the two males as Eciton (Neivamyrmex) fuscipennis, attributing the species authorship to Wheeler (1908). Subsequent authors have followed Smith's lead in awarding authorship to Wheeler. D. R. Smith (1979), however, determined that the correct author for N. fuscipennis should be M. R. Smith, 1942. Watkins (1975) concurred and selected one of the Texas males as lectotype.
