Perla (Perla) obscura Pictet, 1841: 28 ; Perla neotropica Jacobson & Bianchi, 1905: 617 ; Macrogynoplax aterrima Klapálek 1916: 73 ; Kempnyia neotropica, Zwick, 1972: 1168 ; Bispo & Froehlich, 2004b: 107; Bispo & Froehlich, 2008: 62.

Material examined: BR, PR, Morretes: 2 males, 1 female, 11.i.2012, M. C. Novaes & M. P. B. Bertolucci.

Remarks. The above males have a forewing length of 10.1–11.0 mm and the female of 15.5 mm. The head is pale laterally ( Fig. 31 ) and the wings are milky, resembling K. petersorum ( Froehlich, 1996) and differing from the common color pattern of K. neotropica . The subgenital plates of the male ( Fig. 32 ) and female ( Fig. 37 ) and the penial armature ( Figs. 33–35 ), agree with the concept of K. neotropica as presented by Bispo & Froehlich (2008). Therefore, at this time, we accept the above noted differences as variation exhibited by K. neotropica . Further studies, especially molecular analyses of specimens from different localities are required to determine if cryptic species are present.
