"The species of cyphophthalmid opilionids known from the United States and Mexico are surveyed. The genus Neosiro is considered a synonym of Siro; Siro sonoma is described as new. The male genitalia of S. exilis, S. kamiakensis, and S. acaroides are illustrated for the first time, and the male of Neogovea mexasca is newly described. A new scheme of family-level classification is proposed for the suborder worldwide. The family Sironidae Simon is redefined to include the genera Sira, Parasiro, Tranteeva, Odonotosiro, Metasiro, Paramiopsalis, and Suzukielus. Troglosiro is placed here provisionally. The new family Pettalidae is proposed for Pettalus, Purcellia, Parapurcellia, Neopurcellia, Speleosiro, Rakaia, and Chileogovea. The subfamily Stylocellinae Hansen and Sörensen is raised to family rank and redefined to include only the genus Stylocellus. For the genera Ogovea and Huitaca, the new family Ogoveidae is proposed, and for the genera Neogovea, Paragovia, and Metagovea, the new family Neogoveidae. The new arrangement is based upon a cladistic analysis. Arguments against Savory's 1977 proposal to consider the Cyphophthalmi an order of Arachnida separate from Opiliones are presented"--P. [1].
