Although the new genus has the principle synapomorphies of Calopterygoidea, it possesses a unique structure (possible reversal) in the pattern of vein RP1/2.Sinocalopteryx shangyongensis nov. gen., nov. sp. de l’Eocène basal du Sud-Ouest de la Chine est le premier Calopterygoidea fossile de l’Asie du Sud-Est. Bien que le nouveau genre ait les principales synapomorphies des Calopterygoidea, il montre une structure unique (possible réversion) dans le patron de la nervure RP1/2.
