Diagnosis. Male imago: 1) dorsal portion of turbinate eyes oval (Fig. 173 in Cruz et al. 2014); 2) dorsal portion of turbinate eyes in lateral view without constriction; 3) dorsal portion of turbinate eyes stalk height 0.21 × height of dorsal portion; 4) turbinate portion of compound eyes (in lateral view) with anterior and posterior margins divergent; 5) forewing with two brown bands, apical band parallel to posterior margin (Fig. 176 in Cruz et al. 2014); 6) marginal intercalary veins paired (Fig. 176 in Cruz et al. 2014); 7) hind wing with small marks of pigmentation (Fig. 177 in Cruz et al. 2014); 8) costal process of hind wing pointed (Fig. 177 in Cruz et al. 2014); 9) marginal intercalary veins on hind wing present (Fig. 177 in Cruz et al. 2014); 10) abdominal sterna with pair of medioanterior and medioposterior sigilla strongly pigmented; 11) abdominal sterna washed with red spots and with one anterolateral mark; 12) forceps segment I wide at base (Fig. 175 in Cruz et al. 2014); 13) forceps segment III elongate (Fig. 175 in Cruz et al. 2014).

Female imago: 1) forewing with two bands, apical band parallel to posterior margin (Fig. 179 in Cruz et al. 2014); 2) marginal intercalary veins paired (Fig. 179 in Cruz et al. 2014); 3) hind wing with small marks of pigmentation (Fig. 180 in Cruz et al. 2014); 4) costal process of hind wing pointed (Fig. 180 in Cruz et al. 2014); 5) marginal intercalary veins on hind wing present (Fig. 180 in Cruz et al. 2014); 6) abdomen covered by red spots (Figs. 178 and 181 in Cruz et al. 2014); 7) abdominal sterna with pair of medioanterior and medioposterior sigilla strongly pigmented (Fig. 181 in Cruz et al. 2014).

Mature nymph: 1) distal margin of labrum medially with simple spine-setae (Fig. 61B in Nieto 2008); 2) maxillary palp 1.5 × the length of galea-lacinia (Fig. 65 in Nieto 2008); 3) crown of galea-lacinia with two rows of setae; 4) paraglossa with rounded apex (Fig. 66A in Nieto 2008); 5) paraglossa with one tuft of fine and simple setae on apex; 6) metanotum with spines; 7) foretarsus anterior surface with spine-like setae (Fig. 67 in Nieto 2008); 8) hind claw denticles smaller than foreclaw denticles (Fig. 69 in Nieto 2008).

Comments. Until now, C. gloriosus   is considered to be a junior synonym of Callibaetis (A.) fasciatus   . After studying the type of C. gloriosus   , we observed that the most conspicuous diagnostic character of C. (A.) sellacki   is present in C. gloriosus   : an apical band on the female forewing, parallel to the posterior margin. Thereby, C. gloriosus   is proposed here as junior synonym of C. (A.) sellacki   . The type specimens of C. gloriosus   possess damaged forewings ( Fig. 16 View FIGURE 16 B), but the apical band is visible and comparable with those presented by Cruz et al. (2014: Figs. 27D, 27G).

We present figures of the dorsal and ventral habitus of the nymphs of C. (A.) sellacki   ( Figs. 15 View FIGURE 15 A–15B) and the type of C. gloriosus   ( Figs. 16 View FIGURE 16 A–16B).
