Comments. The groups atrebatinus , propinquus , molawinensis in the genus Baetis Leach, 1815 were proposed by different authors in application to local faunas: the group atrebatinus for the European fauna ( Müller-Liebenau 1969), the group propinquus for the North American fauna ( Morihara & McCafferty 1979a; 1979b) and the group molawinensis for the Oriental fauna ( Müller-Liebenau 1984). In other respects these three groups represented one and the same taxon, which was outlined and characterized by Novikova & Kluge (1987) as the taxon Labiobaetis (initially with a rank of subgenus, later the rank was raised to a genus). Recently Labiobaetis contains 170 formally described species (including invalid synonyms) and many undescribed species from Holarctic, Afrotropical, Oriental and Australian Regions.

The genus Labiobaetis has very diverse structure of larvae, imagines and eggs, and attempts to divide it into species-groups were suggested. Particularly, Kaltenbach & Gattolliat (2018; 2019; 2021) established several species groups for Oriental (including New Guinean) species based on larval characters. However, total classification of Labiobaetis is still absent. A species group tricolor can be outlined based on imaginal and larval characters.
