Morphological and molecular evidence support a new species of the genus Ilocomba Brescovit, 1997 (Araneae, Anyphaenidae, Anyphaeninae) from the Andes of Colombia

Abstract

We describe a new species of the genus Ilocomba Brescovit, 1997 from the Andean region of Colombia using an integrative taxonomic approach that combines morphological and molecular data. We assess the phylogenetic position of the new species using four molecular markers: COI, 16S, 28S, and H3. The distinctiveness of the new species, Ilocomba yotoco sp. nov., is supported by its placement in the phylogenetic tree, unique morphological characteristics, and uncorrected pairwise genetic distances. We also provide new morphological data and geographic records for Ilocomba marta Brescovit, 1997. Additionally, we present a distribution map of the genus and an updated identification key for all known species of Ilocomba.
