(2021) , M. juxianensis is a peculiar species among the thomsoni -group because basal lobe is solely possessed by the right paramere. However, the remaining parts of the aedeagus are identical to those of M. aureola and the left paramere has an erose lower margin, where tiny fragments of the linking membrane can be observed under large magnification. We therefore believe that its lower lobe of left paramere had been damaged. Moreover, there is a specimen of M. aureola collected together with the holotype of M. juxianensis ( Fabrizi et al. 2021 ) . The combined evidence suggests that M. juxianensis should be a junior subjective synonym of M. aureola . The parameres of M. aureola illustrated by Fabrizi et al. (2021) are deformed. Here we present photos of an undamaged male genitalia extracted from a fresh individual ( Fig. 2D ).
