Investigations into the Phylogeny of the Lycosoid Spiders and Their Kin(Arachnida: Araneae: Lycosoidea)

摘要

The phylogenetic relationships of spider families classically placed in thesuperfamily Lycosoidea, which possess a grate-shaped tapetum in some or all of the indirect eyes, are examined through exemplar taxa scored for 68 classical or newly elaborated characters. A derived calamistrum, which forms an oval to rectangular patch, is considered a synapomorphy uniting the Lycosoidea and several other genera formerly placed in the Tengellidae and Miturgidae. In the resulting analysis the Lycosoidea are shown to be monophyletic and the Tengellidae and Miturgidae polyphyletic.
