percentages of unnamed (or unidentified) species are the rule in
molecular spider phylogenies that aim at comprehensiveness. Some recent
In our own recent phylogeny of daddy longlegs spiders (Pholcidae) (Eberle et al. 2018) the percentage of unnamed species was at ~22%. The primary aim of this paper is simply to fill gaps, i.e. to name some of the undescribed taxa included in that paper. As a result of this paper and of the simultaneously published paper on Sri Lanka Pholcidae, the percentage of undescribed species is now down to 18% (106 of 600 species).
