Abstract

Zenithoptera Bates, in Selys Longchamps, 1869, is formally characterized, and the synonymy of two Linnean names related to this genus is discussed and Libellula fasciata is proposed as a new synonym of L. americana. Z. americana (L.,1758) Z. viola Ris, 1910, Z. lanei Santos, 1941 and Z. anceps Pujol-Luz (in press) are redescribed, their distinguishing features figured, and a keys are presented. Male and female genital morphology furnished the basis for presentation of combination of characters related with the wing coulor variation and geographical distribution of the species of this genus.
