Platnick, Norman I.Ubick, Darrell.2007-07-102007-07-102007http://hdl.handle.net/2246/586944 p. : ill., maps ; 26 cm.Includes bibliographical references (p. 43-44).The spider genus Zorocrates is revised, and comprises at least 31 species found from the southern United States south to Central America; it provides a notable example of the loss of a functional cribellum within a relatively small (but seemingly monophyletic) group of species. Two specific names are removed from synonymy: Z. gnaphosoides O. P.-Cambridge and Z. mordax O. P.-Cambridge (from Z. fuscus Simon and Z. mistus O. P.-Cambridge, respectively). Two other specific names are newly synonymized: Z. isolatus Gertsch and Davis, with Z. unicolor (Banks), and Z. petersi Kraus, with Z. gnaphosoides O. P.-Cambridge. Males are newly described for Z. badius Simon and Z. pictus Simon; females are newly described for Z. karli Gertsch and Riechert. Twenty new species are described from Texas and Mexico.11347116 bytesapplication/pdfen-USQL1 .A436 no.3579, 2007ZorocratesSpiders -- Southwestern StatesSpiders -- MexicoSpiders -- Central AmericaArachnida -- Southwestern StatesArachnida -- MexicoArachnida -- Central Americatext
