NOTAS SÔBRE TABÂNIDAS BRASILEIROS: II. FIDENA CALLIPYGA N. SP.
Castro, G. M. de Oliveira | Date Issued: 1945
Fundação Oswaldo Cruz. Instituto Oswaldo Cruz. Rio de Janeiro, RJ, Brasil.
Fidena callipyga n. sp. is described from three specimens, in the collections of the INSTITUTO OSWALDO CRUZ. It is related to Fidena ornata kröb., 1931 and Fidena aureopygia Kröb., 1931. It can be distinguished from both by the postfrons which is comparatively broader in relation to the high, by the light golden-yellow color of the beard, in striking contrast to the hairs on the propleurae and anterior coxae, and by the extent of the golden-yellow on the abdomen. In size, ornamentation and principally in the form of the palpi it is nearer to aureopygia. Fidena callipyga n. sp. and Melpia miniatistola (End.), 1925 constitute a pair of convergent forms, they differ however not only as to hairs on the mesonotum, femora and hind tibiae and form of the abdomen, but also as to the color of the beard.
