The genus Neocordulia is represented in neotropical region with 15 species. Out of these, eleven occur in Brazil: N. androgynis, N. batesi, N. carlochagasi, N fiorentini, N. gaucha,  N. machadoi, N. mambucabensis, N. matutuensis, N. pedroi, N. santacatarinensis and N. setifera.  Five larvae of species of Neocordulia genus are known in the Neotropical region: N. androgynis, N. batesi longipollex, N. biancoi, N. setifera and N. santacatarinensis. With the discovery of these two new larvae, the number of known Corduliidae larvae is now seven for the Neotropical region. A collecting trip to the Tapinuã stream (19º58´16´´S/40º31´80´´W), Santa Teresa, Estação Biológica de Santa Lúcia, Espírito Santo State, Brazil resulted in collection of 15 larvae of Corduliidae and in other trip to the Cachoeira da Eubiose (21º43´0´´S/ 44º58´60´´W), São Tomé das Letras, Minas Gerais States, Brazil resulted in collection of one larva, both emerged at laboratory. Specimens were collected with sieve (500 & 956;) from shallow riffles. The drawings were made with the aid of a camera lucida attached to a stereoscopic microscope. Measurements were made with the aid of a Starrett digital caliper. The larva of Neocordulia pedroi distinguished from all other larvae known of Neocordulia by to present the cerci strongly convergent and Neocordulia machadoi by to present cerci slightly convergent.
