Type locality. Neighborhood of San Paolo, Brazil.

Type material. Holotype. Male, Zoological Museum of Oslo University, GOS slide F 12324 View Materials a.

Studied material. 5 parthenogenetic females from pond near Laguna Seca pond, San Josй de Gracia, Aguascalientes, 25.09. 1993, AYS; 38 parthenogenetic females from Pond 4, Mesa Montoro, Calvillo, Aguascalientes, 0 5.10. 1990, AYS.

Comments. Alona ossiani   is a sibling-species to Palearctic Alona affinis (Leydig, 1860)   . These species clearly differs by the male morphology (see Sinev, 1998), but their parthenogenetic females are not obviously distinguishable (Sinev, 2009 a). According to Sinev (2009 a), A. ossiani   is the only species of the affinis   -group known from the Americas. Specimens in our material ( Figs. 10 View FIGURE 10. A – J K–M) demonstrated no significant differences from those from the type population of A. ossiani   (see Sinev, 1998).

Distribution. Alona ossiani   appears to be widely distributed in North and South America, but precise records of this species, with male morphology described, are sparse (Sinev, 2009 a). In Aguascalientes, it is found in cold regions in two mountainous areas: Mesa Montoro mountain, over 2,500 m.a.s.l., and Laguna Seca pond in Sierra Fría mountain, at 3,100 m.a.s.l.
