Abstract

The final-instar larva of Psaironeura tenuissima is described based on reared specimens from Amazonas and Pará states in the Brazilian Amazon. Psaironeura larvae are grouped with Neoneura and Protoneura larvae by having nodated caudal lamellae, however, they can be differentiated by the number of labial palp setae. Psaironeura tenuissima are morphologically compared with P. angeloi larvae as well as those of Neoneura kiautai and Protoneura aurantiaca. The P. tenuissima larva can be distinguished from that of P. angeloi by the shape of the superior margin of prementum, projections on the prothorax, caudal lamellae apex shape, and the number of setae in the paraproct ventral margin setae.
