Abstract
The nymph of Anacroneuria debilis (Pictet, 1841) is described, being the first immature of this genus described in Brazil. It can be distinguished from other described Anacroneuria nymphs by: (1) the presences of a row of fine, long bristles along the tibia; (2) by the absence of long bristles on the frons; (3) due to its distinctive color pattern; and (4) by the presences of rows of bristles on the basal third of the cercus.References
