Wuyjugu Tavares, gen. nov. urn:lsid:zoobank.org:act: 3928672E-13D2-4BCD-AE79-B2A7496A3B05 Type species. Wuyjugu pizai sp. nov. (described below) Etymology. The name is the combination of the words “Wuy jugu”, which is the self-denomination of an indigenous tribe known in Brazil as Munduruku people. The tribe dominated the region of the Tapajós Valley, which is the region where the two specimens were collected. The name is an indigenous Tupi word and must be treated as an arbitrary combination of letters. The gender of the name is being established as neuter. Diagnosis. The body is slender (Fig 1 A–D). The genae has no carinae (Fig. 2A). The tegmina are long and straight, with anterior and posterior margins almost parallel—anterior margin slightly arched (Fig. 2D). Both tegmina lack the anterior branch of posterior Cubitus (CuPa) between the anterior portion of the harp (h1) and the neck, only an irregular fold line is present, marking the division between these two areas (Fig. 2 E–F). The fastigium of the vertex is triangular and conical, as wide as the scapus (Fig. 2 A–B). The mid and anterior zones of the pronotal disk have no lateral carinae, and the posterior zone has only rounded lateral keels (Fig. 2B). The lateral lobes of the pronotum are notably longer than deep, with ventral margin distinctly concave (Fig. 1A; C). The prosternum is smooth. The phallic complex is completely membranous, without any sclerotized appendage or area (Fig. 3 F–I). The ovipositor is very long (almost as long as tegmina and more than 1.5 times longer than the hind femur), very slender, and completely straight (Fig. 1 C–D; 2H). The general form of male cercus (Fig. 3 A–B) reminds that of Ragoniella Chamorro-Rengifo & Lopes-Andrade, with an oblique inward spine and a finger-like projection ventrally. However, this last genus is easily distinguished by the inward spine of cercus much smaller and positioned apically, the presence of scleritis in the phallus and the ovipositor upcurved, boomerang-shaped, shorter than hind femora.
