The only other monograph on the family Heteroceridae was published by Reinhold Charpentier (1965), and this encompassed the species of the Ethiopian region. Charpentier's work included two species level keys, one based on male genitalia, the other on external characteristics. Charpentier saw no justification in dividing the family into any new taxa and he retained all 35 Ethiopian species in the genus Heterocerus.
The only previous comprehensive study of the Heteroceridae family was published by Reinhold Charpentier in 1965, which focused on the Ethiopian region's species. His work included two keys: one based on male genitalia and the other on external features. Charpentier did not propose splitting the family into new taxonomic groups and instead kept all 35 Ethiopian species within the genus Heterocerus.
