Description
Summary:The genus has long been the most speciose within the Opiliones family Triaenonychidae, comprising 63 species and subspecies distributed across New Zealand and South America. Recent molecular studies utilizing Sanger sequencing and ultraconserved elements (UCEs) have indicated that this genus is not monophyletic, and true are actually confined to New Zealand. Here, the morphology of all South American triaenonychids is re-examined and DNA sequence data compiled from three markers (18S rRNA, 28S rRNA and cytochrome oxidase subunit I) for a large number of triaenonychid species, including specimens from all areas with species currently and formerly classified in to reassess their phylogenetic position. Based on our findings we 1) revalidate the genus (Muñoz-Cuevas, 1971) ; 2) describe five new genera: , , , , ; 3) redescribe five species: , , , , ; and 4) describe 22 new species of South American triaenonychids: , , , , , , , , , , , , , , , , , , , , , and Furthermore, we provide detailed illustrations of all the South American species belonging to these lineages formerly classified in .
