The Aphyoditeinae are a taxonomically controversial, subfamily of South American Real tetras (Characidae).

features

The species of Aphyoditeinae are more or less elongated fish and reach body lengths of 2 to 8 cm. Diagnostic features of the subfamily are eight or more slender teeth in a single row on the premaxillary, the size and number of mandibular anterior teeth (eight or more slender teeth), the number of supraneuralia (neural processes) (four or fewer). The sideline does not extend to the caudal fin.

Systematics

The group was set up in 1965 by the French ichthyologist Jacques Géry as a Tribus Aphyoditeini within the Cheirodontinae . On this basis, Juan Marcos Mirande established the new subfamily as part of a phylogenetic analysis based on the morphology, assuming a sister group relationship to the (newly defined) Cheirodontinae.

Genera and species

The subfamily today contains 23 species in eight genera.

Whether the genera compiled here by Mirande, in some cases only on a provisional and provisional basis, actually form a monophyletic unit, however, appears open on the basis of later phylogenomic (based on the comparison of homologous DNA sequences) and morphological studies. In the study by Oliveira et al, the genera they examined were not closely related to one another. Microschemobrycon (investigated species Microschemobrycon casiquiare ) belonged, for example, to the Characinae, with a very basal position within the subfamily. The genus Aphyocharacidium was more closely related to a clade that included the Aphyocharacinae. After a further, combined morphological and molecular study, it should be included in the Aphyocharacinae. Many authors (for example) therefore draw the conclusion that the breakdown into subfamilies tends to be left open until further phylogenetic studies are available.
