Neotropical Osmylidae larvae (Insecta, Neuroptera): description of habitats and morphology

The larval stages of the genus Kempynus Navas, 1912 (probably K. falcatus Navas, 1912 based on the presence of synchronic and sympatric adults) are described for the Neotropical Region for the first time, and the larval stages of Isostenosmylus pulverulentus (Gerstaecker, 1893) are redescribed.
