Taxonomy

Hadromeropsis was described for the first time by W. Dwight Pierce in 1913 (p. 400).^[2] The Central American species were treated by Champion.^[3] The genus was revised by Anne Howden in 1982:^[4] It contains two subgenera: Hadromeropsis (Hadromeropsis) and Hadromeropsis (Hadrorestes).

Description

Howden offered the following diagnosis for Hadromeropsis:

Small to large, 5 to 20 mm in length. Scales never sculptured. Posterior margin of epistoma never carinate or keeled, although margin elevated distally in a few species. Mandible with vestiture of lateral and ventral surface similar to that of rostrum. Pronotum never produced anteriorly over vertex. Female with caudal surface of ventrites 2, 3, and 4 conspicuously elevated, often perpendicular or slanted anteriorly or posteriorly, edge of caudal surface usually sharply delimited; character less developed in male.
