Note.

Eustrophopsis is the most diverse world genus of Eustrophinae , with approximately 55 species, known from Afrotropical, Neotropical and Nearctic regions. Descriptions of the species are scattered through the literature, and there does not exist a comprehensive work on the entire genus, which is in need of revision. Nikitsky (1998: 58) stated that it is "remarkable that Eustrophopsis seems to be absent both from the Oriental Region and Palaearctic. It may be so that it is replaced there by species of the genera Holostrophus and Synstrophus unknown from the Neotropical and Afrotropical regions".

Eustrophopsis was described by Champion (1889) based on his examination of specimens collected in the Neotropics. Specimens that possessed a notched prosternal process were separated from Eustrophinus Seidlitz and placed in Eustrophopsis . Nikitsky (1998) synonymized these two genera, stating that the emarginated prosternal character was not satisfactory to separate them. Therefore, Eustrophopsis became a senior synonym of Eustrophinus .

Although admittedly preliminary, the Nearctic species of Eustrophopsis seem referable into a number of informal groupings: Eustrophopsis confinis (very widely separated eyes); Eustrophopsis bicolor , Eustrophopsis brunneimarginatus , and Eustrophopsis indistinctus (body shape, color pattern and shape of antennomeres); Eustrophopsis arizonensis (very rugose macrosculpture of proepisterna), and Eustrophopsis ornatus and Eustrophopsis crowdyi , sp. n. (enlarged, sexually dimorphic antennomeres, males with distinctive sensilla on antennomeres 5-10).
