ZooBank: urn:lsid:zoobank.org:act:A5287E4A-6D3A-4454-B72C-D80AB1AF072C .

Type genus: Jupiaba Zanata, 1997 .

Included genus: Jupiaba (in part).

Etymology: From the Tupí ju meaning thorn and piaba meaning small fish.

Remarks: Jupiaba was described to include 21 species traditionally classified in Astyanax or Deuterodon , based on six synapomorphies related to the structures of the pelvic girdle and adjacent musculature (Zanata 1997). The monophyly of Jupiaba has never been supported in phylogenetic studies (Oliveira et

al. 2011, Mirande 2019, Melo et al. 2022a), which is reflected in substantial differences in the distribution of teeth and the pelvicfin bone morphology (Zanata 1997, Zanata and Lima 2005). The phylogenetic analysis of UCE loci resolves a monophyletic group containing Jupiaba abramoides (Eigenmann, 1909) , J. anteroides (Géry, 1965) , J. anterior (Eigenmann, 1908) , and J. poranga (type species) that are classified in a newly erected subfamily Jupiabinae ( Fig. 6), partially corroborating previous phylogenetic analyses ( Terán et al. 2020). The current delimitation of Jupiaba is polyphyletic in the UCE phylogeny ( Fig. 6), with species resolving in Hyphessobryconinae [ J. apenima , J. asymmetrica , J. iasy Netto-Ferreira et al., 2009 , J. keithi , J. ocellata (Géry, Planquette and Le Bail, 1996) , J. pirana Zanata, 1997 , J. polylepis (Günther, 1864) , and J.zonata (Eigenmann, 1908) ] and in an unnamed clade with Hemigrammus ora ( J. acanthogaster , J. cf. essequibensis , and J. scologaster ).
