FIGURE 25. Three Anthalona taxa with uncertain identity versus Anthalona verrucosa (Sars, 1901). A.–B. Type species of the genus, Anthalona verrucosa (Sars, 1901) from São Paulo, Brazi (Sars 1901). No holotypes or paratypes were selected by Sars, paralectotypes were selected later by Valdivia-Villar, see Fig. 22. Drawings after Sars (1901; as Alona verrucosa). C.–D. Alona rectangula sensu Daday (1905) = Biapertura pseudoverrucosa pseudoverrucosa (Smirnov, 1971) from Paraguay (Daday 1905). We regard it here as a synonym of A. verrucosa, but more than one species may yet be found in the Neotropics. Drawings after Daday (1905). E.–F. Alona alonopsiformis Brehm, 1933 from Philippines. Identity of this taxon is unknown, no types exist. Drawings after Brehm (1933). G.–J. Alona verrucosa lineolata Chen & Li, 1991 from China. Identity unknown, body shape and striation as Anthalona mediterranea, which may be identical. Drawings after Chen et al. (1991). Habitus of parthenogenetic females (A, C, E, G), postabdomen (B, D, F, H), head pores (I) and labrum (J).
