Rhinoleucophenga punctulata Duda

(Figures 10 a–e; 11a–c)

R. punctulata Duda, 1929: 43 –44; R. punctulata Malogolowkin, 1946: 417, 422; R. punctulata Roque & Tidon, 2008: 97; R. punctulata Vilela & Bächli, 2009: 186 –191; R. punctulata Roque & Tidon, 2013: 119; R. punctulata Poppe et al., 2014: 220, 230, 235.

The identity of all R. punctulata specimens was confirmed through the male terminalia according to the redescription performed by Vilela & Bächli (2009) and through the comparison of the arista branch pattern with R. punctuloides sp. nov. The arista branches are longer and curved (s-shaped) in R. punctulata (Fig. 10 c), while branches are short and straight in R. punctuloides sp. nov. (Fig. 5 d). Because both species occur sympatrically in the Pampas, knowledge of the terminalia of R. punctulata female from the Pampas (Fig. 11 a–c) is also important to the species determination. The females can be differentiated through comparisons of the spermathecal capsule; R. punctuloides sp. nov. presents an invagination in the tip of the spermathecal capsule (Fig. 7 c) that is not seen in R. punctulata (Fig. 11 c).
