( Figs. 19 View FIGURE 19 A–19C)

Callibaetis viviparus Needham and Murphy 1924: 50   ; Domínguez et al. 2006, p. 117; Cruz et al. 2014: 62; Vinasco- Mondragón & Zúñiga 2016: 93.

Known stages. I ♀

Diagnosis. Female imago: 1) forewing with pigmented C, Sc and R1 areas, extending beyond R1 but not forming bands ( Fig. 19 View FIGURE 19 C); 2) forewing with thick cross veins in C and Sc areas ( Fig. 19 View FIGURE 19 C); 3) marginal intercalary veins single ( Fig. 19 View FIGURE 19 C); 4) hind wing with one intercalary marginal vein ( Fig. 19 View FIGURE 19 C); 5) hind wing with quadrangular costal process; 6) body covered with brown spots ( Fig. 19 View FIGURE 19 B); 7) anterolateral spots on abdominal terga and sterna present ( Fig. 19 View FIGURE 19 B).

Complementary description. Female imago: Thorax. Covered with brownish spots. Wings. Forewing ( Fig. 19 View FIGURE 19 C) pigmentation extending beyond R1 but not forming bands; veins light brown; C, Sc and R1 areas with thick cross veins; stigmatic area with 2–3 cross veins touching and 3–4 not touching subcostal vein; marginal intercalary veins single; length of each intercalary vein 0.41 × distance between adjacent longitudinal veins; length of forewing about 2.4 × width. Hind wing hyaline ( Fig. 19 View FIGURE 19 C) and with 14 cross veins; one intercalary marginal vein present. Abdomen. Terga covered with brown spots, with spot anterolaterally ( Fig. 19 View FIGURE 19 B). Sterna with spot anterolaterally ( Fig. 19 View FIGURE 19 B). Caudal filaments lost.

Comments. Vinasco-Mondragón & Zúñiga (2016) recorded C. viviparus   and C. (C.) radiatus   in Colombia based on female imagoes. The morphological evidence to differentiate both species was the shape of the costal process of the hind wing (round in C. viviparus   and truncante or quadrangular in C. (C.) radiatus   ). Studying the holotype of C. viviparus   (mounted on a slide), we observed that one peak of the costal process is turned inward, appearing to be rounded. Thus, the morphological evidence presented by Vinasco-Mondragón & Zúñiga (2016) and Cruz et al. (2014) is not corroborated, not allowing the differentiation of both species. Taking into account the new evidence, association between stages should be made in order to confirm or refute the records from Colombia.

Material examined. Callibaetis viviparus   , female imago (holotype, slide), Brazil, Mato Grosso state, Corumbá municipality, 14.xii.1919, Cornell University n° 643.
