Previous sensuphylogenetic stricto (Calvert), character apparently analyses suggested that the group comprises at least sharedNavicordulia only with aemulatrix (Hagen Selys), three distinct lineages, i.e. Corduliinae , was also reported by Pinto & Lamas (2010).

In South America, there are nine genera and state of Santa Catarina, southern Brazil (Pinto & Lamas 44 species of corduliids recognized, with 11 species in 2010). All of them are from the collection of Richard von MachadoNavicordulia & Costa, making it the second Diringshofen, an amateur German-Brazilian entomologist, largest genus of the continent (Pinto & Lamas 2010). whose collectioncf waset alinherited by the Museu de Zoologia Species of can be distinguished from da Universidade de São Paulo in the year of 1987 after all other corduliids occurring in the New World by the his death ( .
