Genus Aethaloptera Brauer, 1875

Aethaloptera Brauer, 1875: 71 [Type species: Aethaloptera dispar Brauer, 1875 (by monotypy)].

Chloropsyche McLachlan, 1880: 69 [Type species: Chloropsyche evanescens McLachlan , (by monotypy); synonymised by Kimmins, 1962: 96].

Primerenca Navás, 1915: 181 [Type species: Primerenca maesi Navás by original designation and monotypy; synonymised by Lestage, 1919: 293].

Paraethaloptera Martynov,1935:193 [Type species: Paraethaloptera gracilis Martynov , by original designation and monotypy; synonymised by Barnard, 1980: 66].

Diagnosis. This genus can be distinguished from other Macronematinae genera by having ‘false’ discoidal cell on the forewing surrounding nygma, formed by the rejoining of R4 and R5 right after their initial separation ( Barnard, 1980) ( Fig. 1 ). Wings very pale yellow (whitish in alcohol) and with brown spots. Head with two pairs of warts, appearing connected with each other ( Fig. 7 ); posterior warts smaller.
