Callibaetis (Abaetetuba) pollens Needham & Murphy 1924 View in CoL

( Figs. 9 View FIGURE 9 A–10H)

Callibaetis pollens Needham & Murphy 1924: 51 View in CoL ; Nieto 2008: 235; Domínguez et al. 2006: 116; Boldrini et al. 2012: 92; Lima et al. 2012: 306; Cruz et al. 2014: 56; Boldrini & Cruz, 2014: 4.

Known stages. I ♀♂, N.

Diagnosis. Male imago: 1) dorsal portion of turbinate eyes oval ( Figs. 9 View FIGURE 9 A, 10A); 2) dorsal portion of turbinate eyes in lateral view with constriction ( Fig. 10 View FIGURE 10 B); 3) dorsal portion of turbinate eyes stalk height 1.3 × height of dorsal portion ( Fig. 10 View FIGURE 10 B); 4) turbinate portion of compound eyes (in lateral view) with anterior and posterior margins divergent; 5) forewing hyaline ( Fig. 9 View FIGURE 9 B); 6) marginal intercalary veins single ( Fig. 9 View FIGURE 9 B); 7) hind wing hyaline ( Fig. 9 View FIGURE 9 B); 8) costal process of hind wing rounded ( Fig. 9 View FIGURE 9 B); 9) marginal intercalary veins on hind wing present; 10) abdominal terga on anterior margin with a transversal mark of pigment ( Fig. 10 View FIGURE 10 A); 11) abdominal sterna with pair of medioanterior and medioposterior sigilla weak pigmented ( Fig. 10 View FIGURE 10 C); 12) abdominal sterna with black anterolateral mark ( Fig. 10 View FIGURE 10 C); 13) forceps segment I wide at base, with setae on inner margin ( Figs. 9 View FIGURE 9 E, 10G); 14) forceps segment III oval ( Figs. 9 View FIGURE 9 E, 10G).

Female imago: 1) head with a Y mark ( Fig. 10 View FIGURE 10 D); 2) forewings hyaline (Fig. 161 in Cruz et al. 2014); 3) marginal intercalary veins single (Fig. 161 in Cruz et al. 2014); 4) hind wing hyaline (Fig. 162 in Cruz et al. 2014); 5) costal process of hind wing rounded (Fig. 162 in Cruz et al. 2014); 6) marginal intercalary veins on hind wing present (Fig. 162 in Cruz et al. 2014); 7) abdominal terga reddish brown ( Fig. 10 View FIGURE 10 D); 8) abdominal sterna with pair of medioanterior and medioposterior sigilla weak pigmented ( Fig. 10 View FIGURE 10 E); 9) abdominal sterna II to IX with black mark ( Fig. 10 View FIGURE 10 E).

Mature nymph: 1) distal margin of labrum, medially with row of long and bifid setae (Fig. 43B in Nieto 2008); 2) maxillary palp 1.5 × length of galea-lacinia (Fig. 47 in Nieto 2008); 3) crown of galea-lacinia with three rows of setae; 4) paraglossa with rounded apex (Fig. 48A in Nieto 2008); 5) paraglossa with one tuft of fine and simple setae; 6) metanotum with spines ( Fig. 10 View FIGURE 10 H); 7) foretarsus anterior surface without spine-like setae (Fig. 49 in Nieto 2008); 8) hind claw with minute denticles (Fig. 51 in Nieto 2008).

Comments. Cruz et al. (2009, 2014) differentiate C. (A.) pollens and C. (A.) capixaba by the setae on the femur of the nymph (trifid setae absent on the femur of C. (A.) pollens ). We studied the same specimens analyzed by Cruz et al. (2009, 2014) and some of those analyzed by Nieto (2008), and observed trifid setae on the femur of C. (A.) pollens . However, the nymphs of both species can be differentiated by the shape of the apex of paraglossa, being round in C. (A.) pollens (Fig. 48A in Nieto 2008) and truncate in C. (A.) capixaba (Fig. 42A in Cruz et al. 2009); and by the number of tufts of fine and simple setae on the apex of the paraglossa, having one in C. (A.) pollens and three in C. (A.) capixaba .

We present figures of the holotype ( Figs. 9 View FIGURE 9 A–9E) and more recently collected specimens assigned to C. (A.) pollens ( Figs. 10 View FIGURE 10 A–10H) from Brazil.
