| dc.description.abstract | A taxonomic study of the genus Toxomerus (Diptera:Syrphidae) of Ecuador was made. Species were identified by use of published keys and descriptions, comparisons with holotypes, allotypes, and paratypes, and through examination of specimens determined by other syrphid workers. Comparisons were made by removing the genitalia of unknown and determined specimens. The unknown specimens were identified to species and the genitalia of both sexes were drawn and described. Artificial keys were prepared utilizing external morphology excluding genitalic features as well as a key to each sex utilizing genitalic features. Twenty species, including one suggested new species, of Toxomerus from Ecuador were identified. The genitalia of the holotypes of T. eurydice, T. ultimus, and T. cyrillus were identical to the genitalia of the T. idalius holotype, T. sylphus allotype, and T. productus holotype, respectively. Three species are presumed to be represented by these 6 specimens. | |
