The opilionid subfamily Ortholasmatinae (Opiliones, Troguloidea, Nemastomatidae). American Museum novitates ; no. 2757

Abstract

"Three new opilionid species from North America are described: Ortholasma levipes, O. setulipes, and Dendrolasma dentipalpe. The genera Trilasma and Ruaxphilos are synonymized with Ortholasma; the synonymy of Cladolasma with Dendrolasma is confirmed. The new subfamily Ortholasmatinae is established for Ortholasma and Dendrolasma, under the family Nemastomatidae; previously these genera had been considered members of the Trogulidae. Extensive descriptions and illustrations are provided of the morphology of members of the subfamily, together with information on postembryonic development, biogeography, and ecology. A cladistic analysis of the known species is presented"--P. 2.
