(lectotype M0171083!, designated by Lourenço et al. 2020; isolectotypes K000331104!, K000331105!, M0171084!, M0171085!, M0171086!, M0171087!, MEL1540473!, MEL1540474!, MEL1540475!).

Myrcia cuspidata is similar to the case of Myrcia celaenensis (see above). The species has calyptrate flowers but other features such as foliar venation and inflorescence structure are not typical of Myrcia sect. Calyptranthes . The species resembles Myrcia uaupensis (O. Berg 1857 –1859: 516) Gaem & E.Lucas (in Gaem et al. 2020: 299) and Myrcia mcvaughii (B. Holst 2002: 147) E.Lucas & C.E.Wilson (in Lucas et al. 2016: 673), the latter placed in M. sect. Aulomyrcia by phylogenetic analysis ( Santos et al. 2017). For these reasons, the species is considered as belonging to Myrcia sect. Aulomyrcia (see also Gaem et al. 2022).
