The morphological diversity of the Neotropical Cearacesaini Koçak & Kemal, 2010 (Grylloidea, Gryllidae, Hapithinae) is still poorly attested as it is known by only two genera very different in shape and morphology. A new genus and two new species are described: Najtaecesa aratayensis n. gen., n. sp., the type species of Najtaecesa n. gen., from French Guiana, and N. loretensis n. gen., n. sp. from Eastern Peru. Najtaecesa n. gen. is characterized by its very small size, trigonidiine-like body shape, and male genitalia.
