Apion (Trichapion) candyae, new species (San Vicente, El Salvador), forms galls on leaf petioles, petiolets, and midveins of Erythrina berteroana Urban. A member of a poorly understood complex including many species with striking secondary sexual modifications, A. candyae is particularly rich in such modifications. An attempt to determine precise relationships by comparisons of characteristics mentioned in published descriptions failed, because the data matrix was insufficiently rich in usable specializations--i.e., derived characteristics shared among 2 or more taxa. However, presently available data indicate that the narrowest interpretation is of shared ancestry with the Mexican A. sleeperi Kissinger, another species with numerous bizarre male specializations. With some reservations, these 2 species are retained in the nigrum group of the subgenus Trichapion.
