Material. 300 valves; samples AM 10/3, 6–7, 15, 22–25, 27–30.

Dimensions (total range over all samples). R ♀ l = 0.60–0.83 (0.69), h = 0.31–0.45 (0.37; n = 59); L ♀ l = 0.64–0.86 (0.73), h = 0.33–0.48 (0.40; n = 10); R ♂ l = 0.67–0.87 (0.78), h = 0.35–0.43 (0.38; n = 9); L ♂ l = 0.66–0.89 (0.75), h = 0.33–0.45 (0.38; n = 8); Rj(A-1) l = 0.53–0.64 (0.59), h = 0.30–0.34 (0.32; n = 6); Lj(A-1) l = 0.53–0.63 (0.58), h = 0.30–0.33 (0.32; n = 6); Rj(A-2) l = 0.44, h = 0.26 (n = 1); Lj(A-2) l = 0.45, h = 0.27 (n = 1) .

Remarks. This subrectangular to subtriangular, reticulate to coarsely punctate species is very distinct due to its numerous denticles along the entire anterior margin. Juvenile individuals already display this character (e.g. Pl. 10, 49–50). This species occurs in low numbers (except AM10/7 and 30) throughout the upper part of this core. Considerable variations are observed concerning valve size within and between samples ( Fig. 5 View FIGURE 5 ) as well as in the development of its surface ornamentation ranging from reticulated (e.g. sample AM10/30; Pl. 10, Figs. 29–44) to coarsely punctated (e.g. sample AM10/23; Pl. 10, Figs. 9 View FIGURE 9 –16). Occasionally, the anteromarginal (both valves) and the posteroventral (only in right valves) denticulation is almost obscured by the flange (but can be clearly seen in internal view; e.g. Pl. 10, Figs. 11–12).

As already discussed by Gross et al. (2013), Cyprideis pebasae of Muñoz-Torres et al. (1998) and Whatley et al. (1998) is not conspecific with C. pebasae as established by Purper (1979), but represents a discrete taxon. Conversely, Cyprideis lacrimata , described as a new species by Muñoz-Torres et al. (1998) is synonymous with C. pebasae in its original sense (see above).

Possibly, both species names are simply inverted in the publications of Muñoz-Torres et al. (1998) and Whatley et al. (1998). In any case, this taxonomic confusion must be clarified and can not be solved using the invalid species name “ lacrimata ” for this taxon as done before ( Ramos 2006, in part; Ramos et al. 2009; Wesselingh & Ramos 2010; ICZN article 49). A new species name for C. pebasae sensu Muñoz-Torres et al. (1998) and sensu Whatley et al. (1998) is required (ICZN article 23.3.5). Here, we name this species Cyprideis munoztorresi nom. nov. in honour of Fernando Muñoz-Torres. The specimens described by Muñoz-Torres et al. (1998) under C. pebasae form the type series of C. munoztorresi among which the male left valve (FM\UAB\F60, Pl. 4, Figs. 8–9 View FIGURE 8 View FIGURE 9 in Muñoz-Torres et al. 1998) is designated as lectotype (ICZN article 74.7).

Occurrence (of C. pebasae sensu Muñoz-Torres et al. 1998 ). Western Amazonia ( Brazil, Colombia), latest Middle to early Late Miocene ( C. obliquosulcata – C. cyrtoma zone; Muñoz-Torres et al. 2006; chronostratigraphic correlation after Wesselingh & Ramos 2010).
