Record: Tulare Co.: Lange Cave. 
Comment: This is the first record of the order Siphonophorida from a cave in California. The male holotype (the only spec¬

Bibhography: Krejca (2009b); Shear (2009); Marek, Krejca, and Shear (2016). 
ORDER CALLIPODIDA 
Family Schizopetahdae 
Colactis utorum (Chamberlin) (troglophile) 
Records: Inyo Co.: Lower Shoshone Cave; Shoshone Turk Cave; Upper Shoshone Cave (type locality of C. briggsi ). 
Comment: Shear (1974) in the description of C. briggsi speculated that this species may be troglobitic because of its 
reduced pigmentation (light hom brown to pale testaceous as opposed to the usual near black in the genus) and the harsh 
desert environment surrounding the cave. The species does possess numerous black ocelli. Shelley (1996) placed C. brig¬ 
gsi, along with two epigean species in the synonymy of C. utorum.
