Accepted name: Baetis guttata F.-J. Pictet, 1843 nom. dub.

Locus typicus: “ Chili ”.

Type material: Holotype [by monotypy] female imago, not traced.

Remarks: F.-J. Pictet examined a single female from the National Museum of Natural History in Paris. This species certainly does not belong to the genus Ecdyonurus nor to the family Heptageniidae, which is absent from South America. The combination with Siphlonella (Oniscigastridae) proposed by Flowers & Peters (1981) is mainly based on the colour pattern. The holotype is presumably lost and the name Baetis guttata should be considered a nomen dubium.
