The Genus Stridulivelia Hungerford, 1929, Subgenus Aenictovelia Polhemus, 1979 (Hemiptera: Heteroptera: Veliidae): Review and Comparative Morphology

The genus Stridulivelia is exclusive to the Americas, with a Neotropical distribution ranging from Mexico to Argentina. It comprises 16 valid species and is divided into two subgenera: Stridulivelia Hungerford and Aenictovelia J. Polhemus. The subgenus Aenictovelia, found in North America and northern South America, is characterized by the absence of stridulatory structures in its six species. However, photos and detailed descriptions are scarce in the literature for some of them. Here, we provide photos and descriptions of the male genitalia of all species of S. (Aenictovelia): S. chocoana Morales, Molano and Moreira, S. cinctipes (Champion), S. epeixis (Drake and Menke), S. pueblana (Drake), S. secerna J. Polhemus, and S. speciosa J. Polhemus and D. Polhemus, and also present new distribution records for three of these species. A key to species of S. (Aenictovelia), maps with all their geographic records, and a discussion on the morphology of the two subgenera also are presented.
