APOTOMOPS Powell and Obraztsov, 1986

Apotomops Powell and Obraztsov, in Powell 1986: 396; Brown, 1989: 320; Brown and Powell, 1991: 4; Brown, 2000b: 108; Razowski and Becker, 2000: 75.

Type species: Olethreutes wellingtoniana Kearfott, 1907, by original designation.

Diagnosis. Apotomops is superficially and genitalically most similar to Bonagota . Although the relationship between them is not entirely resolved, the two appear to represent monophyletic sister groups. Under present concepts, Apotomops can be defined by the reduced socii that are mostly fused to the tegumen, the development of teeth along the dorsal edge of the sacculus, and the reduced cilia and rounded aspect of the male antennal flagellomeres. Powell (1986) included two species in the genus: A. wellingtoniana (Kearfott) and A. texasana (Blanchard and Knudson) . We add A. carchicola (Razowski and Becker), new combination, A. sololana (Razowski), new combination, A. boliviana, new species, and A. spomotopa, new species . Although all species of Apotomops and Bonagota are similar in facies, A. wellingtoniana and A. texasana are most similar to each other superficially, while A. carchicola and A. boliviana are more similar to species of Bonagota .

Distribution. Apotomops is one of very few genera in Euliini that occurs north of Mexico (e.g., Eulia Linnaeus, Dorithia Powell, Anopina Obraztsov). Apotomops wellingtoniana occurs across Canada from British Columbia (type locality) to Nova Scotia (USNM), and south through the Rocky Mountains to the Mexican states of Durango (UCB), Nuevo Leon, Distrito Federal, and Veracruz (Razowski and Becker 2000). In eastern North America, it ranges as far south as the Great Smoky Mountains in Tennessee (USNM). It is possible that specimens from Mexico are not conspecific with northern A. wellingtoniana, but we could find no characters to convincingly separate the two. Apotomops texasana is known only from Texas; A. carchicola and A. sololana are known only from Ecuador; A. boliviana is known only from Bolivia; and A. spomotopa is known only from Peru.
