Is the existence of two lineages for Hamadryas glauconome (Lepidoptera: Nymphalidae) true? molecular and ecological evidence
The genus Hamadryas has a neotropical distribution. In 1983, the subspecies H. glauconome grisea from Mexico was recognized with subtle and subjective differences in color, size and distribution and limited to the northwest. Since then, there has been a debate about whether it is a different lineage from H. glauconome because adult-stage morphology studies have not found significant differences. This study aims to delimitate H. g. glauconome and H. g. grisea lineages with two sources of evidence: ecological and molecular—the former through ecological niche modeling using the accessible area for the species and estimating the minimum volume ellipsoid overlapping as a fundamental niche using occurrences databases. The molecular evidence is found through the methods of phylogenetic inference and the generalized mixed yule coalescent approach, using sequences of cytochrome oxidase I. Ecological and molecular evidence suggest that H. g. grisea is a different lineage from H. glauconome. Also, molecular evidence of a third lineage from the south of Texas needs further study. This study suggests that different evidence should be provided when morphology is not enough for delimiting species, especially in recently diverged species. Furthermore, the H. g. grisea cytochrome oxidase I sequence (658 bp) is published for the first time.
