Pleistocene Refugia Inferred from Molecular Evidence in a Forest-Dwelling Harvestman (Arachnida, Opiliones, Gonyleptidae) Support a Biogeographic Split in Subtropical Argentina.

Abstract excerpt

This paper addresses the population genetic structure of the forest-dwelling gonyleptid Geraeocormobius sylvarum (Arachnida, Opiliones). Phylogeographic analyses using cytochrome oxidase subunit I (COI) were conducted on 186 individuals from 43 localities in Argentina and Paraguay, arranged into nine operational sectors and defined upon geographic and vegetation features. Given the current environmental...
