Uchuca ferreirai ( Piza, 1976)

Ailtomia ferreirai Piza, 1976: 370 , Type locality: Humaitá , Amazonas, Brazil . Type: Male , ESALQ (Escola Superior de Agricultura " Luiz de Queiroz ")

Uchuca macroptera Montealegre-Z & Morris, 2003 syn. nov.: 510; 513; 529 ( Fig. 5 C, H, M, R, W; Fig. 8, Table 7). Type locality: Route del Paujil Orito, Departamento del Putumayo, Colombia, Type: Male, MNHN (Muséum National d'Histoire Naturelle); Chamorro-Rengifo et al., 2011: 8.

Uchuca ferreirai Chamorro-Rengifo & Braun, 2010: 44 , 54 ( Table 1 ); Chamorro-Rengifo & Lopes-Andrade, 2014: 166; 167; 168; 170; 175; 181; 198 (Fig. 12, 13, 73, 98)

Uchuca ferreirai and Uchuca macroptera are the only two long-winged species known in the genus in which tegmina surpasses the abdomen’s apex. Both species are morphologically similar. Chamorro-Rengifo & Braun (2010) analyzed the type material of U. ferreirai and concluded that the male cerci of both species were significantly different. However, these differences were not clarified in the work.

We also analyzed the type specimens of Piza (1976) and compared to the diagnostic characters of the original description of U. macroptera , present in Montealegre-Z & Morris (2003), and no differences were found on the male cerci of either species. No differences were found on tergite X and the subgenital plate. Chamorro-Rengifo & Lopes-Andrade (2014) also published images of phallus of what would become U. ferreirai . The phallus presented in that work was different from the one present by Montealegre-Z & Morris (2003), especially in the position and direction of the titillatory processes. However, after dissecting the phalli of some macropterous specimens, in an attempt to precisely clarify the correct identity of the specimens we had, we realize that the position and direction of the titillator sclerites changed accordingly with the eversion of the phallus. In other words, if the phallus is everted, it matches with the phallus presented in Fig. 5 W by Montealegre-Z & Morris (2003) to U. macropetra ( Fig. 4 A); on the other hand, if the structure is inverted, it matches with the phallus presented in Fig. 13 by Chamorro-Rengifo & Lopes-Andrade (2014) to U. ferreirai ( Fig. 4 B). So, we concluded that these purported species are actually the same.

In the type description of this species, Piza (1976) wrongly said that the city Humaitá belonged to Rondônia State, but in fact it belongs to Amazonas State. Here we also amplify the known occurrence of this species to Pará State (see Distribution of Uchuca ).
