Alonella dadayi Birge, 1910 View in CoL
( Fig. 5D View Figure 5 )
Material examined: Four adult parthenogenetic females ( FDRS493 ) .
Remarks: Species named in many studies as Disparalona dadayi or Phryxura dadayi , but Smirnov (1996) considered Alonella dadayi as the valid name for this species. Additionally, Fryer (1997) wrote that the description of Phryxura Müller, 1867 was based on a single abnormal specimen, making the name invalid according to the rules of the International Code of Zoological Nomenclature. Alonella dadayi has a remarkable rostrum, which is long and curved, posteroventral corner of valves with 1–7 denticles with short setulae between them, postabdomen with preanal angle prominent. The high variability of some morphological traits recommends a wide revision of A. dadayi .
Distribution: Neotropics ( Kotov et al., 2013). In Brazil it occurs in the Amazônica, Tocantins /Araguaia, São Francisco, Paraná, Paraguai, Atlântico Nordeste Oriental, Leste, Sudeste and Sul hydrographic regions ( Elmoor-Loureiro, 2017).
