Taxonomic history
The was established by Obraztsov in 1962 with Anopina ainslieana as the . A major revision by & Powell in 2000 transferred numerous species from related genera and described many new species, effectively redefining the genus boundaries based on genitalic .
Species diversity
The exhibits high concentrated in Mexico, with many having restricted geographic ranges. This pattern suggests significant localized speciation, possibly associated with the complex topography of the Mexican highlands.
