Taxonomic history

Replacement name for Acantholepis Mayr, 1861 (junior homonym of Acantholepis (Pisces) Kroyer, 1846: 98), and hence is the first available replacement name: Bolton, 1995b: 33.
[Lepisiota incorrectly as junior synonym of Acanthomyrmex: Brown, 1973b PDF: 181; Snelling, 1981: 397. In both publications Acanthomyrmex is an error for Acantholepis Mayr, 1861.]

This genus has been known as Acantholepis MayrHNS,1861 for about 130 years but this name is a junior homonym of Acantholepis KrayrHNS, 1846. LepisiotaHNS Santschi, 1926 is the first available replacement name (Bolton, 1994). The new combination was then designated by Bolton five years later in the new general catalogue of the ants of the world (Bolton 1995).
