Marchena cluster

Closely related in SNP–PCA to A. c. sielmanni from Pinta . Also shares mitochondrial haplotypes, and only rather weakly differentiated morphologically from Pinta specimens. To ensure consistency among subspecies delimitation and microsatellite loci clustering, and considering that the RADseq tree does not support a cluster of ( Pinta + Marchena ), we here suggest considering the Marchena population as a new subspecies A. c. hayampi subspec. nov., but we are aware that future studies might reveal this population to be better classified as A. c. sielmanni along with the Pinta population, and this nomen to become a junior synonym of sielmanni.
