Abstract

The genus Trilasma Goodnight & Goodnight, 1942 is reinstated for Mexican ortholasmatines, and Cladolasma Suzuki, 1963 is reinstated for two species from Japan and Thailand, C. parvula Suzuki, comb. n. and C. 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., T. hidalgo sp. n., T. trispinosum sp. n., T. ranchonuevo sp. n., T. petersprousei sp. n. and T. chipinquensis sp. n. are from Mexico, and T. 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.
