2.2. Taxonomie und Faunistik

Evans(1952: 54) beschrieb das Taxon als "Polygonus leo ssp. hagar". Ihm lagen dabei zur Erstbeschreibung zwar 40 Exemplare vor, aber alle nur aus Jamaica: "Sub-sp. hagar nov: ♂ Jamaica: type B.M. B.M. 30 ♂ 10 ♀ Jamaica.".

Zhang et al. (2023: 16) werten dieses Taxon und andere bisherige Unterarten von P. leo zu Arten auf: "Polygonus arizonensis (Skinner, 1911), stat. nov., Polygonus histrio Röber, 1925, stat. rest., Polygonus pallida Röber, 1925, stat. nov., and Polygonus hagar Evans, 1952, stat. nov. are species distinct from Polygonus leo (Gmelin, [1790])". Sie begründen das damit, dass die Barcoding-Abstände zwar nicht sonderlich groß sind, sich aber ganz mit den genetischen Untersuchungen des Z-Chromosoms decken: "Genomic sequencing and analysis of Polygonus leo (Gmelin, [1790]) (type locality America, likely in Hispaniola) specimens from across the range reveal that all five subspecies of P. leo are genetically differentiated at the species level in both nuclear (Fig. 13a) and mitochondrial (Fig. 13b) DNA. E.g., COI barcodes of the closest taxa, i.e., the nominotypical P. leo (Fig. 13 purple) and Polygonus (Acolastus) histrio Röber, 1925 (type locality “vermutlich aus Panama”, but likely Cuba as suggested by DNA comparison) (Fig. 13 green) differ by 2.1% (14 bp). Therefore, we propose that Polygonus arizonensis (Skinner, 1911), stat. nov., Polygonus histrio Röber, 1925, stat. rest., Polygonus pallida Röber, 1925, stat. nov., and Polygonus hagar Evans, 1952, stat. nov. are species, not subspecies."
