Serna-Muñoz, Sebastian & Wolff, Marta, 2024, Leaf-footed Bugs (Hemiptera: Heteroptera: Coreidae) of Colombia: Annotated checklist, distribution, and description of a new species, Zootaxa 5459 (1), pp. 1-95 : 12

Tribe Acanthocephalini

The tribe Acanthocephalini was reviewed by Brailovsky (2021), who also offered a complete key to genera. Minor taxonomic changes have been made since; Olivera et al. (2023) revalidated the genus Spilopleura Stål and therefore, the couplet 20 of the key provided by Brailovsky (2021) should be modified to lead to a new couplet instead to Acanthocephala Laporte :

21 Pronotum dorsally tuberculated; apex of scutellum flat, never incrassated or with a callosity; male metathoracic acetabulum unarmed................................................................................ Acanthocephala

- Pronotum dorsally without tubercles; apex of scutellum flat, never incrassated of with a callosity; male metathoracic acetabulum with a rounded or conical projection............................................................. Spilopleura

This tribe is represented by 32 species in the country, with 12 here reported for the first time. All known Colombian species of Acanthocephalini can be identified with the existent literature, being the most relevant: the reviews of Acanthocepahala Laporte ( Olivera 2022), Ctenomelynthus Breddin ( Brailovsky 2018) , Salapia Stål ( Brailovsky & Barrera 2023a) and Spilopleura Stål ( Olivera, Melo & Dellapé 2023) ; the keys to the species of Antipetalops Brailovsky ( Brailovsky 2021a) , Laminiceps Costa ( Brailovsky & Barrera 2023b), Lucullia Stål ( Brailovsky 2017) , Meluchopetalops Breddin (Brailovsky 2009a) and Petalops Amyot & Serville ( Brailovsky 2021b) ; and the description of the second species of Leptopetalops Breddin ( Brailovsky 1991a) .
