Diagnosis. Male imago: 1) dorsal portion of turbinate eyes oval ( Fig. 1View FIGURE 1 in Cruz et al. 2009); 2) dorsal portion of turbinate eyes in lateral view with constriction; 3) dorsal portion of turbinate eyes stalk height 2.6 × height of dorsal portion; 4) turbinate portion of compound eyes (in lateral view) with anterior and posterior margins divergent; 5) forewing with brownish stigmatic area and small brownish spots along costal vein ( Fig. 3View FIGURE 3 in Cruz et al. 2009); 6) marginal intercalary veins paired ( Fig. 3View FIGURE 3 in Cruz et al. 2009); 7) hind wing hyaline ( Fig. 4View FIGURE 4 A in Cruz et al. 2009); 8) costal process of hind wing rounded ( Fig. 4View FIGURE 4 B in Cruz et al. 2009); 9) marginal intercalary veins on hind wing absent ( Fig. 4View FIGURE 4 B in Cruz et al. 2009); 10) abdominal terga III, V and VII laterally with inverted V mark; 11) abdominal sterna covered with spots and with pair of medioanterior and medioposterior sigilla weak pigmented; 12) forceps segment I wide at base ( Fig. 5View FIGURE 5 in Cruz et al. 2009); 13) forceps segment III oval ( Fig. 5View FIGURE 5 in Cruz et al. 2009).

Female imago: 1) forewing with C and Sc areas pigmented overlapping R1, after R2 with lighter pigmentation ( Fig. 7View FIGURE 7 in Cruz et al. 2009); 2) marginal intercalary veins paired ( Fig. 7View FIGURE 7 in Cruz et al. 2009); 3) hind wing with brown mark near costar process ( Fig. 8View FIGURE 8 A in Cruz et al. 2009); 4) costal process of hind wing rounded ( Fig. 8View FIGURE 8 B in Cruz et al. 2009); 5) marginal intercalary veins on hind wing absent ( Fig. 8View FIGURE 8 B in Cruz et al. 2009); 6) abdominal terga III, V and VII laterally with inverted V mark ( Fig. 6View FIGURE 6 in Cruz et al. 2009); 7) abdominal sterna covered by spots ( Fig. 9View FIGURE 9 in Cruz et al. 2009); 8) abdominal terga with medial longitudinal mark ( Figs. 22View FIGURE 22 B–22D); 9) abdominal sterna medially, on anterior margin, without one large spot.

Mature nymph: 1) maxillary palp 1.3 × the length of galea-lacinia ( Fig. 15View FIGURE 15 in Cruz et al. 2009); 2) below maxillary palp insertion on outer margin with tuft of robust spine-like setae ( Fig. 15View FIGURE 15 in Cruz et al. 2009); 3) paraglossa with row of spine-like setae on ventral surface ( Fig. 16View FIGURE 16 A in Cruz et al. 2009); 4) segment III of labial apically rounded ( Fig. 16View FIGURE 16 A in Cruz et al. 2009); 5) metanotum without spines; 6) foretarsus anterior surface without spine-like setae ( Fig. 17View FIGURE 17 A in Cruz et al. 2009); 7) hind claw denticles smaller than foreclaw denticles ( Fig. 18View FIGURE 18 E in Cruz et al. 2009).

Comments. After analyzing the types, it is clear that the pigmentation pattern and morphology of C. (C.) fluminensis  are identical to those of C. (C.) zonalis  . Both species possess forewings with C and Sc areas pigmented overlapping R1, after R2 with lighter pigmentation ( Fig. 7View FIGURE 7 in Cruz et al. 2009); marginal intercalary veins paired ( Fig. 7View FIGURE 7 in Cruz et al. 2009); costal processes of hind wings rounded ( Fig. 8View FIGURE 8 B in Cruz et al. 2009); marginal intercalary veins on hind wings absent ( Fig. 8View FIGURE 8 B in Cruz et al. 2009); abdominal terga III, V and VII laterally with inverted V marks ( Figs. 22View FIGURE 22 C–22E and Fig. 6View FIGURE 6 in Cruz et al. 2009); abdominal sterna covered by spots ( Figs. 22View FIGURE 22 C– 22E and Fig. 9View FIGURE 9 in Cruz et al. 2009); abdominal terga with medial longitudinal marks ( Figs. 22View FIGURE 22 B–22D); 9) abdominal sterna medially, on anterior margin, without one large spot. Thereby, C. (C.) fluminensis  is considered a junior synonym of C. (C.) zonalis  .

The specimen studied by Navás (1915) from La Plata, Argentina, is damaged, and we analyzed it only through photographs. Further studies are necessary to determinate if the specimen should be designated as lectotype or if a neotype should be designated.
