Redescription of Schizomus crassicaudatus (Pickard-Cambridge) and diagnoses of Hubbardia Cook, Stenochrus Chamberlin, and Sotanostenochrus new genus, with description of a new species of Hubbardia from California (Arachnida: Schizomida: Hubbardiidae)

Redescription of Schizomus crassicaudatus (Pickard-Cambridge) and diagnoses of Hubbardia Cook, Stenochrus Chamberlin, and Sotanostenochrus new genus, with description of a new species of Hubbardia from California The Pearce-Sellards Series is an occasional, miscellaneous series of brief reports of Museum and Museum associated field investigations and other research. All manuscripts are subjected to extramural peer review before being accepted. The series title commemorates the first two directors of the Texas Memorial Museum: Dr. at Austin. Both professors are now deceased. ABSTRACT Schizomus crassicaudatus (Pickard-Cambridge) from Sri Lanka is redescribed from the type series, and lectotypes of Nyctalops crassicaudata and N. tenuicaudata are designated. Hubbardia Cook, previously considered a synonym of Schizomus Cook, is considered valid and rediagnosed to include species from California and Arizona (U.S.A.). The family Hubbardiidae Cook has priority and therefore is used rather than Schizomidae Hansen and Sorensen. Likewise, Hubbardiinae Cook is substituted for Schizominae Hansen and Sorensen. Additional descriptive notes and records are provided and a lectotype is designated for Hubbardiapentapeltis Cook. Hubbardia idria new species is described from San Benito County, California. Additional records are included for H. briggsi (Rowland). A key for identification of males of Hubbardia is presented. The native (introduced elsewhere) North and Central American genus Stenochrus Chamberlin is rediagnosed for most species of the Schizomus mexicanus, pecki, and goodnightorum groups. Sotanos-tenochrus, new genus, is described for Schizomus mitchelli Rowland and Schizomus cookei Rowland and is known only from caves in San Luis Potosi and Tamaulipas, Mexico.
