Five previously described species are recognized as valid: affinis, foveolatus, hirsutus, humeralis, and maculosus. One new species, tumulosus, from Texas is described as new. The following new synonymy is proposed: longior LeConte 1856 (= affinis LeConte 1856) and albidus Pierce 1909 (= maculosus Pierce 1909). A neotype is designated for T. humeralis (Say). A key to identify the species is provided, with various illustrations of key morphological features characterizing these species. Additionally, distribution maps, species descriptions, and species differentiation for each species is provided. A cladistic hypothesis of the included species is presented.born digitalmasters thesesengCopyright and other restrictions may apply. User is responsible for compliance with all applicable laws.
