Abstract: " The Nearctic genus Triznaka is reviewed with T. sheldoni, n. sp. described from White Pine County, Nevada, U.S.A. The new species is compared to T. pintada and T. signata. The distinctive armature of the aedeagus and color of the pronotum distinguish the male, while the emarginate to notched subgenital plate and color pattern of the pronotum distinguish the female. The new species is primarily restricted to the Great Basin biogeographic region."
