RESUMEN
Abstract Rhinoleucophenga pallidaHendel, 1917 (type species of the genus) is redescribed based on its female holotype and a male from a nearby locality, and Rhinoleucophenga obesa (Loew, 1872) on its two syntypes, which are designated as the male lectotype and a female paralectotype. Both are valid species. A proposal is made to establish the genus Pseudophortica Sturtevant, 1918 (type species R. obesa), a junior synonym of Rhinoleucophenga, to subgenus rank and include all species of Rhinoleucophenga described or redescribed from males except R. pallida, which is unique in having a remarkable pedunculate surstylus, among other differences. The North American R. obesa is compared to its closest sibling, the South American species Rhinoleucophenga gigantea (Thomson, 1869). The occurrence of R. obesa in Brazil is also questioned, as suggested long ago by Marshall R. Wheeler. The specimens from Brazil previously identified as such most probably belong to the new species described in the present paper as Rhinoleucophenga (Pseudophortica) cantareira sp. nov. (type locality: Parque Estadual da Cantareira, City of São Paulo, State of São Paulo, Brazil). Numerous photomicrographs of their habitus and male terminalia taken with a Smartphone's rear camera and digitally stacked to create images with greater depth of focus are provided.
RESUMEN
ABSTRACTHere we describe seven new species of Limnophora from Ecuador: Limnophora bifasciatasp. nov. from Napo, Quito; Limnophora equatoriensissp. nov. from Zamora-Chinchipe, Zamora; Limnophora femurosetalissp. nov. from Zamora-Chinchipe, Zamora; Limnophora lamasisp. nov. from Zamora-Chinchipe, Zamora; Limnophora longivittatasp. nov. from Napo, Quito; Limnophora penaisp. nov. from Azuay, Cuenca and Limnophora polletisp. nov. from Napo, Quito. We provide an identification key for the ten recognized species of Limnophora from Ecuador, including L. marginata Stein, 1904, L. pica(Macquart, 1851) and L. saeva (Wiedemann, 1830). We also redescribed Limnophora marginata Stein, 1904, and designated designed lectotype male and paralectotypes males and females of the species.
