Abstract
A new species of Shelfordina Hebard is described. Liosilphoidea Hanitsch is synonymized with Shelfordina Hebard, and four of its species are redescribed. The monotypic genus Delosia Bolívar, closely related to Shelfordina, is rediagnosed, and its type species D. ornata, previously known only from the Seychelles, is reported from Sri Lanka; a new species of Delosia from Sri Lanka is described. The monotypic genus Duryodana Kirby is rediagnosed and its type species redescribed.
