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).
