Abstract:

A cladistic analysis of the opilionid superfamily Ischyropsalidoidea revealed three groups of genera, each probably monophyletic, and recognized here as families. The family Ischyropsalididae Simon is redefined to include only the genus Ischyropsalis, the family Sabaconidae Dresco is expanded to include Sabacon (= Tomicomerus, new synonymy) and Taracus, and the family Ceratolasmatidae is described as new for the genera Ceratolasma, Hesperonemastoma, Crosbycus, and Acuclavella, new genus. Acuclavella consists of four new species from Idaho and Washington: cosmetoides, shoshone, merickeli, and quattuor. Crosbycus dasycnemus (Crosby) is redescribed and illustrated, and new distribution records are given.
