The Type Specimens of the Odonata in the Entomological Institute, Hokkaido University Author Syoziro Asahina text Insecta matsumurana 1961 24 57 65 journal article http://doi.org/10.5281/zenodo.3516659 2ba41a83-aa08-498a-8d7c-3a5c3debfa99 3516659 1. Orolestes selysi MacLachlan, 1895 = Megalestes mirabilis Matsumura, 1913 Megalestes mirabilis Matsumura, 1913 , p. 50, ♂ , “Taiwan” ( syn. nov .). From the venation it is clear that this insect does not belong to the Synlestid genus Megalestes but to Orolestes in the true Lestidae . Chen (1950) recognized “ Orolestes [ Insecta Matsumurana , Vol. 24 , No. 1, March, 1961 ] mirabilis Mats.” as a good species, but I am of opinion that the Formosan species, both the clear-winged O. koxingai Chen (1950) and the dark-winged O. mirabilis , perhaps are identical with O. selysi MacLachlan known from Assam. There are three male cotype specimens in H. U. collection: the one bearing the label “ Megalestes paradoxa Og.; Megalestes mirabilis Og.; Horisha, iv, 1908” should be chosen as lectotype .
