Lischke failed to illustrate the species at date of introduction of the taxon. It was figured, however, by Lischke one year later (1874: Pl. 2 figs. 24-25).
The specimens figured by Kaicher (1982: card 3431), Okutani (2000), and Nishi et al. (2012: Pl. 48 fig. 3) are the slender morph of this species. On the other hand, the specimen figured by Kaicher (1982: card 3438) as Amalda urashima (Taki) does involve the present species.
The specific epithet "albicallosa" as given by authors (Sterba, 2001), is a spelling error.
