Colonus hesperus (Richman & Vetter, 2004) - Jumping Spider

(previously Thiodina hespera)
Of the three Colonus species in North America C. hesperus is the only one found on the west coast. This southwestern species ranges from Texas to California and south into Baja California and Mexico. While the prominant black blotches around the eyes are found on other female Colonus, the lack of abdominal stripes separates C. hesperus from the other two species.
