New species and records of ortholasmatine harvestmen from México Honduras and the western United States (Opiliones Nemastomatidae Ortholasmatinae)

摘要

The genus Trilasma Goodnight & Goodnight, 1942 is reinstated for Mexican ortholasmatines, and Cladolasma Suzuki, 1963 is reinstated for two species from Japan and Thailand, Cladolasma parvula Suzuki, >comb. n. and Cladolasma angka (Schwendinger & Gruber), >comb. n. Eight new species in the subfamily Ortholasmatinae Shear & Gruber, 1983 are described, as follows: Ortholasma colossus >sp. n. is from California, Trilasma tempestado >sp. n., Trilasma hidalgo >sp. n., Trilasma trispinosum >sp. n., Trilasma ranchonuevo >sp. n., Trilasma petersprousei >sp. n. and Trilasma chipinquensis, >sp. n. are from México, and Trilasma tropicum >sp. n. from Honduras, the farthest south for a dyspnoan harvestman in the New World. A new distribution record for Martensolasma jocheni Shear 2006 is given. The recently described Upper Cretaceous amber fossil Halitherses grimaldii Giribet & Dunlop 2005 is not a member of the Ortholasmatinae, but is likely a troguloidean of an undiagnosed family.
