Type genus: Saicireta Melo and Coscarón, 2005 .

Diagnosis: Postocular region protuberant, and with simple thin setae ventrally (Fig. 6A); anteocular region shorter than postocular region (Fig. 6A); second visible labial segment shorter than third one (Fig. 6A); posterior margin of scutellum entire (Fig. 6C); ventral surface of protibia with both simple and spiniform setae (Fig. 6E); paramere nearly straight, wider at apex, with a process on the lateral submedial margin (Fig. 6F); and gonocoxa 8 rectangular.

Examined material: Saicireta correntina Melo and Coscarón, 2005: one male, holotype, ARGENTINA: Corrientes, Ituzaingó, 27°28 ʹ S, 56°34 ʹ W, Rincón Santa María Reserve, 26.iv.2003 / Saicireta correntina Melo and Coscarón, 2005 / he-10284 (MLP). Four males, one female, paratypes [same data as holotype]/he-10286–10289/he-10285 (MLP).

Redefinition of Saicini

Considering the phylogenetic results that help redefine the newly circumscribed Saicini, we use the optimization of the characters from our analyses to complement and modify the diagnosis offered by Standring et al. (2023), propose two new subtribes, and give a diagnosis for each genus. Furthermore, we present for the first time a key to the genera of Saicini of the world.
