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 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 A–15B) and the type of C. gloriosus (Figs. 16 A–16B).
