 Diagnosis. A Mecistocephalus species with 45 leg­bearing segments. Body length reaching at least 7 cm. Each clypeal plagula about 3.5 times as wide as long. Anterior ala of the labrum subrectangular, with the medial margin not reduced to a vertex; posterior ala subrectangular, with the external margin longer than the medial margin. Forcipular article I with only one distal tooth.   
 Type material. Holotype: sex not stated, 70 mm long, adult (Takakuwa, 1938d).   
 Type locality. ‘Makurazaki (Kagosimaken)’, Kyushu (Takakuwa, 1938d).   
 Depository of type material. The holotype is probably lost (see Discussion).   
 Material examined. None.   
 Description. Body reaching at least 7 cm. Body colour light brownish­yellow, head and forcipular segment darker. Head about 1.4 times as long as wide. Clypeus: clypeal ratio about 2.0; areolate part of clypeus without smooth insulae, each side with 3 setae; plagulae without evident sensilla or setae, each plagula about 3.5 times as wide as long. Labrum: anterior ala subrectangular, its medial margin longer than the medial margin of the posterior ala; posterior ala subrectangular, the external side enlarged in form of a rounded lobe, so that the external margin is longer than the medial one. Spiculum well developed; buccae with setae in the posterior half only. Mandible: about 7 lamellae; first lamella with about 5 teeth; average intermediate lamella with about 15 teeth; margin of the basal tooth with spiniform processes. First maxillae: anterior corners of coxosternum not projecting. Forcipules: article I about 1.5 times as long as wide, with one distal tooth; articles II and III each with a poorly developed tooth; tarsungulum with one basal tooth shallow and rounded. A total of 45 leg­bearing segments. Ratio between the length of the first leg and the length of the second about 0.9. Sternal sulcus not furcate. Last leg­bearing segment: sternum about 1.6 times as long as wide, with a pair of lateral notches.
