James A. Slater, Jane E. O'Donnell


Cistalia micans a new species from Brazil, is described and figured. The highly modified nature of the sperm reservoir in the Lethaeini is discussed. The potential importance of sperm reservoir morphology in understanding phylogenetic relationships within the tribe is noted. The iridescent head patches of Cistalia are discussed in relation to other genera and to sperm reservoir modifications. Figures of the sperm reservoir, clasper, genital capsule, and SEM photographs of the iridescent head patches are included.
