Genus Monocesta Clark, 1865

Monocesta Clark, 1865: 264

(type species Monocesta imperialis Clark, 1865 , by subsequent designation of Weise 1924).

Remarks

Although the elytra in this genus are pubescent, the setae are easily overlooked in some species. The key allows for correct identification, even if the elytra are interpreted as being asetose. The genus includes 28 described species, occurring in the United States through much of South America, and in West Indies. See Figs 1 , 146 , and 195.
