Remarks

DeLong & Martinson (1972) described Gypona viridans based on a single male specimen from Santa Catarina State, Southtern Brazil ( Fig. 21A–B ). The holotype of Costanana asymmetrica was collected by Heinrich Wilhelm Schott, Austrian botanist taxonomist of Araceae Juss. , who spent four years in Brazil (1817–1821) studying the flora in locations in Rio de Janeiro State such as Cabo Frio, Rio Paraíba, Rio Paraibuna, Cantagalo and Cachoeira de Macacu. This species was described by DeLong & Freytag (1972b) based on this single male specimen ( Fig. 21C–E ) that strongly contrasts the other species of Costanana in having the coloration uniformly yellow, the crown surface with oblique-rugose striae (like in figure 25D), and the alar appendix undeveloped. We also studied two male specimens from Minas Gerais State, Brazil ( Fig. 21F–G ). Curiously, one of the specimens has the branched process at the left side of the aedeagus as in G. viridans and the other at the right side as in C. asymmetrica . After comparing these two specimens with the illustrations and descriptions of G. viridans and C. asymmetrica , we concluded that are no differences that can separate these two species and therefore they should be considered as synonyms.
