Abstract

This paper presents a taxonomic review of the genus Boreocanthon Halffter, restored generic sta­tus, a group of ball-rolling (telocoprid) dung beetles (Coleoptera: Scarabaeidae: Scarabaeinae) endemic to North America. The genus, heretofore treated as a subgenus of Canthon, comprises 13 species, each keyed, diagnosed, illustrated and presented with information on distribution, relationships, and biology (*signifies restored generic combination): *Boreocanthon ateuchiceps (Bates, 1887); B. coahuilensis (Howden, 1966); *B. depressipennis (LeConte, 1859c); *B. ebenus (Say, 1823); *B. forreri (Bates, 1887); *B. integricollis (Schaef­fer, 1915); *B. lecontei (Harold, 1868); *B. melanus (Robinson, 1948); *B. praticola (LeConte, 1868); *B. probus (Germar, 1823); *B. puncticollis (LeConte, 1866); *B. simplex (LeConte, 1857); as well as Boreocanthon halff­teri Edmonds here described as a new species. Other actions taken are a) Canthon mixtus Robinson declared junior subjective new synonym of Boreocanthon puncticollis; b) Canthon bisignatus Balthasar, 1939, declared junior subjective new synonym of Boreocanthon simplex; c) Boreocanthon coahuilensis (Howden) new ge­neric combination; and d) neotype designated for the type species of the genus Boreocanthon, Ateuchus ebenus Say, 1823, here Boreocanthon ebenus (Say).

La localidad tipo aproximada de Chrysina adelaida (Hope, 1841) (Coleoptera: Scarabaeidae: Rutelinae) se fija en las montañas del sureste de México. Chrysina occidentalis Robacker and Hawks se describe como una nueva especie de la Sierra Madre Occidental en el noroeste de México con base en comparaciones morfométricas de adultos y cápsulas genitales con las de C. adelaida del sureste de México y con las de C. adelaida (de los autores) de la vecina estados al sur de la Sierra Madre Occidental.
