( Fig. 2D–G View Figure 2 )
Material examined: One adult parthenogenetic female ( FDRS487 )
Remarks: The single known species of affinis -group from the Neotropics. Recently, a new subspecies from North America was described based on male morphology, Alona ossiani herricki Sinev, 2013 ( Sinev, 2013). Regarding Brazilian fauna, A. ossiani has a singular morphology and can be recognized by elongate body with length reaching over 1mm, posterior border of head shield triangular and two connected main head pores; postanal margin elongated with about 50% of length of postabdomen itself, distal angle rounded, 15–17 merged marginal denticles.
Distribution: Neotropics ( Sinev, 1998; Sinev and Silva-Briano, 2012). In Brazil, A. ossiani occurs in the Amazônica, Tocantins /Araguaia, Paraná, Paraguai, São Francisco, Atlântico Nordeste Ocidental, Nordeste Oriental, Leste, Sudeste, and Sul hydrographic regions ( Elmoor-Loureiro, 2017; Sousa et al., 2014).
