RESUMO
Larva, subimago, imago and eggs of Guajirolus ektrapeloglossa Flowers 1985 are described based on reared males and females from the type locality in Panama and a reared female from Peru. Structure and development of male genitals testify that the Neotropical taxon Guajirolus/g1 (incl. Chane) does not belong to Labiobaetini Kluge Novikova 2016 and, therefore, is not related to the Afrotropical genus Pseudopannota Waltz McCafferty 1987. At the same time, larvae of Guajirolus have striking similarity with that of Pseudopannota. The existent descriptions of Guajirolus nanus Lugo-Ortiz McCafferty 1995, G. queremba Nieto 2003 and G. flowersi Thomas Dominique (in Thomas, Dominique Orth) 2005 do not contain characters allowing to distinguish them from G. ektrapeloglossa. Thus, new synonymy is proposed: G. ektrapeloglossa (= G. nanus syn. n.; G. queremba syn. n.; G. flowersi syn. n.). Among the characters described as species-specific for Guajirolus rondoni Salles 2007, only the shape of labial palps allows to distinguish it from G. ektrapeloglossa.

A new definition for the genus Moribaetis Waltz McCafferty 1985 is given. Its type species, Moribaetis maculipennis (Flowers 1979) is redescribed based on male and female imagoes reared from larvae near the type locality in Panama. Larvae, formerly wrongly attributed to Moribaetis salvini (Eaton 1885), and a male imago, formerly wrongly attributed to Moribaetis macaferti Waltz 1985, belong to a new species Moribaetis latipennis sp. n., which is described here based on a male imago reared from larva in Panama. Both species, M. maculipennis and M. latipennis sp. n., are distinct from M. salvini, which is known as a single male imago (lectotype) from Costa Rica. All other species, formerly attributed to Moribaetis, are excluded from this genus; a new combination Caribaetis macaferti comb. n. is proposed for the species originally described as Moribaetis macaferti Waltz (in Waltz McCafferty) 1985, and a new combination Baetis (Rhodobaetis) mimbresaurus comb. n. is proposed for the species originally described as Moribaetis mimbresaurus McCafferty 2007.
