Taxonomic history
The was erected by Augustus Radcliffe Grote, a prominent 19th-century American entomologist known for his work on North American Lepidoptera. The type Eucaterva variaria was described simultaneously with the genus in 1882. E. bonniwelli was added by Cassino & Swett in 1922.
Research significance
Eucaterva variaria appears in records due to its inclusion in studies of Coccygomimus sanguinipes . This association has generated more documentation for E. variaria than for E. bonniwelli.
