Remarks. This species was described by Froehlich (2002) based on a single specimen collected in Nova Friburgo, Rio de Janeiro State. In the specimens studied above, the mean length of the forewings of the males is 11.25 mm (10–12 mm) and females 16 mm (15–17 mm). Anacroneuria flintorum has been recorded in streams of the mountainous regions of southeastern and southern Brazil (Froehlich, 2002; Bispo & Froehlich, 2004a). This brown species exhibits much variability in color pattern (Bispo & Froehlich, 2004a). However, the penial armature of all specimens examined is elongated and has hooks well separated from the vesicles, agreeing with the original description of A. flintorum (Froehlich, 2002) .
