The phylogenetic relationships of the components of the Hermanella generic complex were studied by Flowers & Dominguez (1991). Although Leentvaaria almost surely belonged to this 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 Neehamella and is included within the Hermanella complex. The nymph of L. palpalis Demoulin is redescribed based on the new material.
