Antennal sensilla of Rhodnius

By scanning electron microscopy, sensilla type and distribution were studied on the antennae of ten species of Rhodnius. No sexual dimorphism was apparent. Intraspecific differences in sensillar pattern were shown to be potentially useful in species determination and to agree with results from biochemical studies and previous morphometric studies in terms of species affinities. © 1994 Wiley-Liss, Inc.
