Ichneumon? yezoensis Matsumura, 1912

Ichneumon (Matsumuraius) yezoensis Matsumura, 1912: 105–106, plate XLVII, 5, ♀. Type lost (Townes et al., 1965).

Original description: “Black, closely fine punctures, with short fuscous hairs. The apices of the mandibles, the palpi, the 2 nd and 3 rd abdominal segments on each anterior half yellowish brown. The middle parts of the antennae, the tegulae, the scutellum and a spot on each hind margin of the last 4 segments yellowish white. Metanotum reticulated. Wings subhyaline, somewhat infuscated, veins fuscous, stigma fulvous. Legs dark brown, the apico-frontal part of the anterior femur, the same tibiae and tarsi, a spot of each middle and posterior tibia near the base and a spot of each hind coxa above yellowish white. Length 25 mm ”.

Remarks: This species had been included in the genus Coelichneumon (“ Ichneumon ” sensu Townes) by Townes at al. (1965) (see also Yu et al. 2016). The color pattern of metasoma is very different from all known species of Coelichneumon, but would be typical for several species of Ichneumon and/or Diphyus . Therefore, this taxon is excluded from Coelichneumon here, it probably belongs to Ichneumon .
