Stimpson, 1858, listing several syntypes collected by P.F. von Siebold from Japan in the years 1823 to 1829, deposited in the then Rijkmuseum van Natuurlijke Historie (RMNH) in Leiden, and preserved either dry or in alcohol. From these they selected a lectotype, a young male (42 by 24 mm; RMNH 379) preserved in alcohol. No further or detailed descriptions of the material were provided. Although they did provide photographs of several specimens, the lectotype was photographed still inside the bottle (viz. Yamaguchi and Baba, 1993: fig. 137A) and no definitive or diagnostic features of its morphology could be discerned. The collections of the RMNH are now housed in the Naturalis Biodiversity Center, Leiden, and photographs of the lectotype (Fig. 2) were kindly provided to the authors by Dr. Charles Fransen. From these photographs, the diagnostic morphology of the 6th pleomere (Fig. 2B) and the 90-degree bend of the G1 (Fig. 2C) can already be observed even in such a young specimen. Furthermore, although the fresh coloration of this species was not recorded by either

, later observations of topotypic material show that the purple spots on the P5 propodus and dactylus, as well as the more profuse but scattered spotting on the dorsal carapace, and the dark colored spines on the anterior margin of the P1 merus are consistently observed (Fig. 1E, F; also Sakai, 1976: pl. 120 fig. 1; Miyake, 1983: pl. 29 fig. 1).

In a photograph of the presumably newly preserved holotype, the pigmented spots on the left P5 propodus and dactylus are still there (Stephenson, 1961: pl. 2 fig. 4), although these have since faded and can no longer be seen during the present examination of the holotype.
