Callibaetis willineri Navás 1933: 115 View in CoL ; Gillies 1990: 30; Domínguez et al. 2006: 117; Nieto 2008: 240; Cruz et al. 2014: 63. Callibaetis alegre Traver 1944: 45 . (syn. by Gillies 1990)

Known stages. I ♀♂, N

Diagnosis. Male imago: 1) dorsal portion of turbinate eyes oval ( Fig. 20 View FIGURE 20 H); 2) dorsal portion of turbinate eyes in lateral view without constriction; 3) dorsal portion of turbinate eyes stalk height 0.75 × height of dorsal portion; 4) turbinate portion of compound eyes (in lateral view) with anterior and posterior margins divergent; 5) forewing hyaline ( Fig. 21 View FIGURE 21 G); 6) marginal intercalary veins paired ( Fig. 21 View FIGURE 21 G); 7) hind wing hyaline ( Fig. 21 View FIGURE 21 H); 8) costal process of hind wing rounded; 9) marginal intercalary veins on hind wing absent ( Fig. 21 View FIGURE 21 H); 10) abdominal terga VII – X darker ( Fig. 20 View FIGURE 20 H); 11) abdominal sterna covered with spots, all sterna with one medial mark on anterior margin ( Fig. 20 View FIGURE 20 G); 12) abdominal sterna with pair of medioanterior and medioposterior sigilla weak pigmented ( Fig. 20 View FIGURE 20 G); 13) forceps segment I wide at base ( Fig. 21 View FIGURE 21 I); 14) forceps segment III oval ( Fig. 21 View FIGURE 21 I).

Female imago: 1) forewing with C and Sc areas pigmented overpassing R1, after R2 pigmentation with large degree of intensity ( Figs. 21 View FIGURE 21 A, 21C, 21E); 2) marginal intercalary veins paired ( Figs. 21 View FIGURE 21 A, 21C, 21E); 3) hind wing usually with one brown mark near costal process ( Figs. 21 View FIGURE 21 B, 21D); 4) costal process of hind wing rounded ( Figs. 21 View FIGURE 21 B, 21D); 5) marginal intercalary veins on hind wing absent ( Figs. 21 View FIGURE 21 B, 21D, 21F); 6) abdominal terga I –VIII with anterolateral spot, terga II – IX with medial longitudinal mark, terga III, V and VII laterally with inverted V mark ( Figs. 20 View FIGURE 20 A, 20C, 20E); 7) abdominal sterna covered with spots, with one medial mark on anterior margin ( Figs. 20 View FIGURE 20 B, 20D, 20F); 8) abdominal terga with medial longitudinal mark ( Figs. 20 View FIGURE 20 B, 20D, 20F).

Mature nymph: 1) maxillary palp shorter than apex of galea-lacinia (Fig. 80 in Nieto 2008); 2) below maxillary palp insertion on outer margin without tuft of robust spine-like setae (Fig. 80 in Nieto 2008); 3) paraglossa with row of spine-like setae on ventral surface (Fig. 81 in Nieto 2008); 4) segment III of labial palp apically rounded (Fig. 81 in Nieto 2008); 5) metanotum without spines; 6) foretarsus anterior surface without spine-like setae (Fig. 82 in Nieto 2008); 7) hind claw denticles smaller than foreclaw denticles (Fig. 84 in Nieto 2008).

Comments. The nymphs of C. (C.) willineri and C. (C.) zonalis are similar, but they can be differentiated by the length of the maxillary palp, which is shorter than the galea-lacinia in C. (C.) willineri and longer in C. (C.) zonalis . Cruz et al. (2014) equivocally presented a female C. (C.) willineri labeled as C. (C.) guttatus (see more comments about similar species and its differentiation in C. (C.) guttatus and C. (C.) jocosus ).

We present photographs of the female imago and male imago ( Figs. 20 View FIGURE 20 A–20H).

The specimens studied by Navás (1915) from San Miguel, Buenos Aires, Argentina, were not found, thus a lectotype was not designated.
