Abstract
The Leptophlebiidae family of mayflies is diverse, with over 640 species and 140 genera worldwide. One of its subfamilies, Terpidinae, is restricted to the Neotropical region and consists of three genera, including Fittkaulus, which have four South American species. This paper redescribes the male imago and proposes a new synonym based on the rearing of nymphs identified as F. cururuensis collected in streams in the Caatinga and Amazon Forest regions of northern and northeastern Brazil. The male imago can be differentiate by having the following combination of characteristics: upper portions of eyes on short stalk; forewing with reddish brown maculae in costal, subcostal and radial sectors; abdomen whitish, with black stripes on posterior margin and dark brown maculae on lateral margins on terga I–VII; penis with proximal half fused; distal half divided, tubular and apically pointed, with latero-dorsal lobes.
