While there are a few reports on myriapod fauna of Tôhoku District (the Northern Part of Honshû), there seems to be no report on myriapods of Towada District. Towada District here, is meant by the area around the big lake, Towada which measures 48km. round, spreading over Aomori and Akita Prefectures. The junior author, Shinohara, had a chance to visit the Lake and, although he could collect only five species of Diplopods and four species of Chilopods, he was lucky in founding among them two new species. Descriptions on them is stated herebelow. What is learnt as a result of consideration on generic diagnoses of Genus Kopidoiulus and Genus Ikahoiulus is also stated. We also added remarks on myriapods found in Irimizu Limestone Cave, Fukushima Prefecture.Epanerchodus towadaensis Shinohara sp. nov.Body length about 18-28mm, width of postcephalic somites 2.5-3.5mm. General color of dorsum darkish brown but legs and somites are yellowish brown. Collum semicircular.Carinae are more or less narrow and produced at caudal end in a short after about the sixth postcephalic plate, and more strongly produced in posterior segments.Tibiotarsus of gonopods of male clubbed with distal portion of it divide in two blades. Distal end of main blade is a little inflated and short bifurcated, but shorter blade rolled outside. Femuroprocess large, and horn long and slender.Holotype: a male (body length 25mm) obtained at Towada, Aomori Prefecture on Oct. 9, 1955. Allotype: a female (body length 28mm). Data same as above. Type specimens were collected by Shinohara and are preserved in his collection.Fusiulus komatsui Shinohara sp. nov.Body length about 17mm. Body width about 1.0mm. General colour brownish black and legs are yellow with darkish brown spots. Number of segments 48 in male. Repugnatorial pores light yellow, fixed the position behind the suture of segments.Setae of the first pair of legs are (1)+(3-4)+(3+5). Inner base and distal end of the second joint of the first pair of legs are areolate, and process of the knee is projected slightly. Penis bifurcate and projects over the anterior margin of coxae of the second pair of legs.Pregonopod of male resembles to that of F. quadratus, but inner angle of distal margin more or less like a protuberance. Postgonopod with thin blades on distal end, and outside of it with two uncertain processes but without cilia on the whole surface of gonopods.Holotype: a male obtained at Towada on Oct. 9, 1955 by Shinohara. The type is preserved in Shinohara's collection.
