Perla obscura Pictet, 1841: 269 ; Perla neotropica Jacobson & Bianchi, 1905: 617 ; Kempnyia neotropica, Zwick, 1972: 1168 ; Bispo & Froehlich, 2008: 64; Froehlich, 2010: 181; Froehlich, 2011: 133; Novaes & Bispo, 2014: 464.

Material examined. Brazil, Santa Catarina, Grão Pará (28o08’57’’S and 49o21’17’’W): 1 male, 16.xi.2012 – 08.i.2013 07.i.2013, malaise trap, LCP, MCN and MFH. Grão Pará, P. E. Serra Furada (28o09’07’’S and 49o23’18’’W): 2 males, 16.xi.2012 – 08.i.2013, malaise trap, LCP, MCN and MFH.

Remarks. The above males have forewing lengths of 11.9–15.7 mm. The penial armature ( Figs. 35–37 ) agrees with Bispo & Froehlich (2008) illustrations. Although all the specimens studied here have the penial armature apparently identical to the redescription presented by Bispo & Froehlich (2008), individual specimens from the above material listed, differ in color patterns. The specimen shown in Fig. 31 is brown, which is considered the typical color of K. neotropica . However, the head laterally and the wings of the specimen shown in Fig. 32 are whitish. This morphotype occurs in other areas of southern Brazil ( Novaes & Bispo, 2014). To resolve the taxonomic status of these specimens, molecular analyses would be useful. Presently, we assume that these pale specimens are within the known range of variation of K. neotropica .
