MARQUES-COSTA, Ana Paula  and  CAVICHIOLI, Rodney Ramiro. Taxonomic revision, cladistic analysis and description of new species of Aglaenita Spinola (Hemiptera, Cicadellidae, Neocoelidiinae). Rev. Bras. entomol. [online]. 2006, vol.50, n.3, pp. 355-378. ISSN 0085-5626.  http://dx.doi.org/10.1590/S0085-56262006000300006.

Aglaenita and its four species are revised. Nine new species are described. A cladistic analysis was performed based on 22 morphological characters and 15 terminal taxa, using two species of Biza as outgroup. This analysis shows Aglaenita as a monophyletic genus and the relationship among its species were: (A. spatulata sp. nov. ((A. dubia, A. elegans) ((A. bicornis sp. nov., A. spinipenis sp. nov.) (A. bifurcata sp. nov. (A. affinis sp. nov. ((A. bipunctata (A. similis, A. tridentata sp. nov.)) (A. longicornis sp. nov. (A. coariensis sp. nov., A. unciformis sp. nov.)))))))). The thirteen species are illustrated and keyed, and their known geographical distribution is given. The female of A. elegans is described for the first time.
