Comments. Many species of the genus Callibaetis have a history of poor, inaccurate, or even absent, illustrations. In order to maximize the possibility of a reliable identification, here we present photographs of the complete dorsal and ventral habitus of the male and female imagoes (Figs. 2 A–2D), a photograph of the ventral view of the male genitalia, mounted on a slide (Fig. 2 F), photographs of the dorsal habitus of the nymphal exuviae (Fig. 2 E) and a detailed illustration of the labrum (dorsal and ventral views) (Fig. 2 G). For more, see morphological comments under C. (A.) pollens.
