Morphological delimitation of the genus Cobanus F.O. (Araneae: Salticidae: Euophryini) with a description of two new species from Colombia

Abstract

Recent work on Neotropical jumping spiders continues to reveal the morphological complexity, phylogenetic relationships, and high taxonomic richness of groups that have not been reviewed in years. Here, we focus on clarify the limits of the genus Cobanus F. O. Pickard-Cambridge, 1900, and transferred some species misplaced in Sidusa peckham & peckham, 1895 to Cobanus. We use an integrative approached of total evidence (DNA + morphology) to produce phylogenetic hypotheses using maximum parsimony (MP), maximum likelihood (ML), and Bayesian methods (BI). Cobanus is strongly supported in all analyses. Based on morphological synapomorphies, we transferred five species to Cobanus and established the following new combinations: Cobanus bifurcata (Chickering 1946) stat. reinst., Cobanus cambridgei (Chickering 1946) stat. reinst., C. electa (Chickering 1946) stat. reinst., Cobanus mandibularis (Peckham and Peckham, 1896) stat. reinst., and Cobanus unicolor (F. O. Pickard-Cambridge 1900) stat. reinst. Additionally, two new species of Cobanus from Colombia, Cobanus chocquibtownsp. n. and Cobanus muelonasp. n., are described. Finally, based on the original proposal of the genus, C. mandibularisstat. reinst. is restored as the type species of the genus Cobanus.
