Of the six North American (north of Mexoco) spiders in the manni group Metaphidippus chera has the widest range with records from California and Utah east to Oklahoma and Texas and south through Baja and Mexico. The other fairly widespread congener Metaphidippus manni ranges west from Arizona to California and north to British Columbia. While M. chera overall shows more white markings it shares with M. manni bicolored chelicerae with large areas of white scaling.
