The genus Leentvaaria was established by Demoulin in 1996 for a single species, L. palpalis, known from a few nymphs from Surinam. Since then, there was no other report on this specie. The phylogenetic relationships of the components of the Hermanella generic complex were studied by Flowers and Domínguez (1991). Although Leentvaaria almost surely belonged to the complex, it was not included because the necessary characters were not available at that time. Recently, we have obtained new nymphal material of Leentvaaria from Brazil, that allowed us to obtain the nymphal characters required to establish the relationships of Leentvaaria with the other components of the Hermanella complex. In this study Leentvaaria appears as the sister group of Needhamella and is included within the Hermanella complex. The nymph of L. palpalis Demoulin, is redescribed based on the new material.
