Oecetis cassicoleata Quinteiro & Holzenthal 2017 (Fig. 4)

Material examined: Brasil, Pará, Santa Luzia do Pará Rio Aripé, Comunidade Tentugal, 01°19’54.2”S, 47°02’16,2”W, 19.xi.2020, alt. 34 m., lençol, col Quinteiro, F.B, Costa, A.M., Moura, L., Saldanha, G., 3 males (MPEG). Same data except chácara prof Elizélia, 01°22’30”S, 47°03’18.5”W, 20.xi.2020, alt 50 m., 1 male (MPEG) .

Distribution: Brazil (Bahia, Pará).

Remarks: The species O. cassicoleata was described for the western region of the state of Bahia (Quinteiro & Holzenthal 2017), in the savanna ecosystem, the Cerrado biome. In this study, it is recorded in the state of Pará, in the Amazon rainforest. It is worth noting that the species was described based on a single specimen (Quinteiro & Holzenthal 2017) and its distribution may be broader than previously known. The holotype did not have a phallic spine (Quinteiro & Holzenthal 2017), which could be due to a clearing artifact. In the four specimens collected in northeastern Pará, it was possible to observe the presence of such a structure (Fig. 4). The phallic spine of specimens of O. cassicoleata collected in Pará is long and helically coiled (Fig. 4D), viewed laterally, and in dorsal view similar to the phallic spine of O. excisa, as described by Quinteiro & Calor (2015).
