Morphological studies of androconia were performed for 13 Celastrina species using a digital microscope with Z ‐stacking mode. Whereas C. ladon lacked androconia, the remaining 12 species were found to possess fan‐shaped androconia on the dorsal wing surfaces. The androconia of these species shared the following common features: smaller size than standard color‐producing scales, absence of dentate termini and presence of crossrib perforations. In addition, some species were characterized by unique microstructures in their androconia. The androconia of C. argiolus iynteana possessed a rounded lamellar contour, while those of C. lavendularis himilcon and C. echo cinerea were tapered on the basal end. The average number of longitudinal ridges of C. argiolus ladonides and C. filipjevi (17.1) were greater than the average number of 12 species (14.3). These results suggest that the morphological traits of androconia in microdomain, such as the shape of the lamellar form and the average number of longitudinal ridges, are useful to identify species in the genus Celastrina .
