Unnamed subfamilp

Included genera: Hemigrammus (in part), Jupiaba (in part).

Definition: The least inclusive crown clade that contains Jupiaba acanthogaster (Eigenmann, 1911) and Jupiaba scologaster (Weitzman and Vari, 1986) . This is a minimum-crown-clade definition. See Figure 6 for a reference phylogeny of the clade.

Remarks: Analysis of the UCE loci resolves a monophyletic group composed of Jupiaba acanthogaster , J. scologaster , Hemigrammus ora Zarske et al., 2006 , and a new species tentatively identified as Jupiaba cf. essequibensis (Eigenmann, 1909) ( Fig. 6). Species classified as Jupiaba and Hemigrammus are consistently resolved among several characid lineages ( Oliveira et al. 2011, Mirande 2019, Melo et al. 2022a). The unnamed clade resolved in the UCE phylogeny does not include the type species of those genera Jupiaba poranga or Hemigrammus unilineatus (Gill 1858) . We understand that smaller named clades are preferable for the sake of classification rather than sinking species in a large subfamily. In addition, this structure retains the existing family-group designations Stethaprioninae and Pristellinae. The type species of Jupiaba and Hemigrammus are not placed inside the clade, which thus requires the description of a new genus before designating the subfamily.
