C169ACA2A1425FF7BAC768106E5BAC64.taxon	etymology	Etymology. The species name is a masculine adjective derived from “ overlooked ” in Latin. Since the description by Kishida (1928) of D. pulcher (as Mecistocephalus pulcher), this new species has been overlooked for 90 years, despite documentation of its distribution as Dicellophilus in the Sendai-shi, Miyagi Pref. (Takakuwa 1940).	en	Tsukamoto, Sho, Eguchi, Katsuyuki (2024): Integrative taxonomy of Dicellophilus Cook, 1896 (Chilopoda, Geophilomorpha, Mecistocephalidae) in Japan, with a description of a new species.
