The biodiversity of Neotropical shore flies (Diptera, Ephydridae) is only now becoming evident, as reflected in the discovery of 13 new species that are described in this comprehensive study of the genus Lamproclasiopa Hendel. The genus now comprises 24 species, of which one, L. laevior Cresson, occurs in the Indian subcontinent. All remaining species are found in the New World, and there, primarily in the Neotropics. The species were revealed through detailed studies of adult morphology, including minute structures of the male terminalia. A phylogenetic perspective is provided for the genus, and all species are included within species groups. Each species is documented with accurate illustrations of the morphology, including colour photographs of many adults.
