Studies on Phaneropterinae: The short-winged bush katydids, Odonturini sensu lato, Barbististini and their allies (Orthoptera: Tettigoniidae). Twelfth contribution to the suprageneric organization of phaneropterines

This contribution to the study of phaneropterine katydids, focuses on the worldwide, short-winged taxa traditionally assigned to the tribes Odonturini and Barbitistini. The status and limits of both tribes are reviewed, redescribed, and identification keys to tribes, subtribes, and genera are provided. Odonturini, with members in Europe, Africa, and the Americas, is redefined based on morphology to include only two genera, Odontura and Odonturella stat. rev.

(the latter elevated to genus rank), and restricted to the western Mediterranean. Barbitistini, historically the best-studied tribe, remains unchanged. Three new tribes are derived from Odonturini: Monticolariini trib. nov., grouping seven genera from eastern Africa; Dichopetalini trib. nov., with ten genera from North America; and Anisophyini trib. nov., with two subtribes, Anisophyina subtr. nov., and Angarina subtr. nov., comprising eight genera from South America.

The South American tribes Cosmophyllini and Aniarellini trib. nov. (the latter divided into three subtribes: Aniarellina subtrib. nov., Hyperophorina subtr. nov., and Tetanina subtr. nov.) are also defined and delimited, now including taxa formerly placed in Odonturini. Morphology proved efficient for delimiting the suprageneric taxa studied, with the terminalia of both sexes and male genitalia being among the most useful characters, which were traditionally underutilized in diagnosing the analyzed taxa.

Eight new genera are described: Hempia gen. nov. and Massaium gen. nov. (Monticolariini trib. nov.); Tedcohnia gen. nov. and Maxium gen. nov. (Dichopetalini trib. nov.); Hellerium gen. nov., and Lorieriella gen. nov.

(Anisophyini trib. nov.); Nickleium gen. nov. (Cosmophyllini); and Buzzettium gen. nov. (Aniarellini trib. nov.).

Anisophya is divided into three subgenera: Anisophya s.s., Anisophya (Brevianisophya) subgen. nov., Anisophya (Castellium) subgen. nov. The genus Caimanellus is redescribed, including the previously unknown male characters. The genus Xenicola stat. rev. is revalidated, having been recently synonymized under Angara.

The following new combinations are proposed: Hempia jagoi (Ragge, 1980) comb. nov., H. hanangensis (Hemp, 2009) comb. nov., and Massaium insolitum (Ragge, 1980) comb. nov. (all originally described in Odonturoides); Tedcohnia cultricerca (Strohecker, 1945) comb. nov., T. alfredoi (Barrientos-Lozano & Rocha-Sánchez, 2013) comb. nov., T. geovanyi (Barrientos-Lozano & Rocha-Sánchez, 2015) comb. nov., T. hypsibates (Cohn, Swanson & Fontana, 2014) comb. nov., T. padrisima (Cohn, Swanson & Fontana, 2014) comb. nov., T. pityophila (Cohn, Swanson & Fontana, 2014) comb. nov., and T. robertoi (Barrientos-Lozano & Rocha-Sánchez, 2015) comb. nov.

(all previously placed in Pterodichopetala); Maxium neomexicanum (Barrientos-Lozano & Ramírez-Núñez, 2013) comb. nov. (formerly in Acanthorintes); Hellerium schoenemanni (Karsch, 1889) comb. nov.; Nickleium biforma (Nickle, 2011) comb. nov., N. careomacula (Nickle, 2011) comb. nov. (both formerly in Anisophya); Lorieriella transfuga (Brunner von Wattenwyl, 1878) comb. nov.

(formerly in Cohnia); Buzzettium borellii (Giglio-Tos, 1897) comb. nov. (previously in Hyperophora); and Xenicola caayari (Fianco, 2025) comb. nov., X. flavolineata (Fianco, 2025) comb. nov., and X. rubra (Fianco, 2025) comb. nov. (all originally described in Angara).

The following species regain their previous combinations after being recently placed in Angara: Xenicola superba (Brunner von Wattenwyl, 1891) comb. reinst., X. brauni Fianco, Engelking & Faria, 2020 comb. reinst., X. dohrni (Brunner von Wattenwyl, 1891) comb. reinst., X. nunoi Fianco, 2023 comb. reinst., X. taroba Fianco, Faria & Braun, 2019 comb. reinst., and X. xukrixi Fianco, Faria & Braun, 2019 comb. reinst. All changes and other taxonomic acts are justified and summarized in three annotated lists to facilitate understanding of the modifications presented in this contribution.

The status, placement, convergence, and distribution of the studied tribes are discussed, contrasting the former taxonomic arrangement with the new classification of short-winged phaneropterines.
