The new species differs from other species of the genus due to the following combination of characters: ocelli present; malar sulcus between the eye and the base of the mandible (Figs 3A, 6A); brachypterous, but with membrane broadly expanded (Figs 2A, B, 3B, 5A, B, 6E); female penultimate mesotarsomeres with asymmetrical lobes (Fig. 6C); female penultimate metatarsomeres with the distal region wider than the proximal region and symmetrical lobes (Fig. 6D); T 1 with a transverse carina and without median sulcus posterior to transverse carina (Figs 3B, 6B); male genitalia with two preapical processes.</p><p>Description.

Legs. Profemur 1.67× as long as wide; metafemur 3.42× as long as wide; outer hind tibial spur present, inner hind penultimate metatarsomere symmetric (Fig. 6D); penultimate metatarsomere with the distal region wider than the proximal region (Fig. 6D).

Metasoma. Dorsal surface of T1 with transverse carina, without median sulcus posterior to transverse carina (Fig. 6B); stridulatory organ present on T3 (Fig. 5B).</p><p>Etymology. The name of the new species is a direct reference to cashew (Caju, in Portuguese), a name given to the peduncle (pseudofruit) attached to the “nut” (fruit) of the cashew tree ( Anacardium occidentale L.), a plant typical of northeastern Brazil with high socioeconomic importance for the region. This fruit also gave its name to the natural reserve (RPPN do Caju) where the new species was found.</p><p>Distribution. Brazil, Sergipe state (Fig. 7).</p><p>Biological aspects. Based on what we know about the species’ biological aspects, it seems to prefer environments with a greater abundance of trees and shrubs, as well as denser leaf litter. These factors contribute to a lower average temperature and higher relative humidity in these places (Brito et al. 2023), where its hosts probably live.</p><p>Remarks. Holotype (MFCE14404): right antenna broken, flagellomeres 7 to 11 glued in a triangle next to the specimen. The paramere, volsella, penis valve, and the sterna 6, 7 and subgenital plate, removed during the dissection of the genitalia, are stored in a microtube filled with glycerine and pinned next to the specimen.</p></div>	https://treatment.plazi.org/id/0381AF216A2A953DA69652D8FAA524A2	Public Domain	No known copyright restrictions apply.
