Genus: Kyhytyuska CORTES, MAXWELL & LARSSON, 2021
Etymology: The genus name is derived from the ancient language of the Muisca people and culture, an ancestral indigenous group that inhabited the Altiplano Cundiboyacense in Colombia since the sixth century. The name is a combination of kyhyty that is the verb 'to cut with somthing sharp' and suka, that is the particle of 'the one that'. The combination kyhyty-suka thus means 'the one that cuts with something sharp' in honour of the ancient Muisca culture and reference the unique dentition of this taxon.
