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.
Kempnyia puri sp.nov. is described from male specimens from Rio de Janeiro State, southeastern Brazil. This species is distinguished from its congeners by the male genitalia bearing moderately long and curved hooks with apex directed laterad and a large and rounded dorsal projection of the penial ring.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
