• 論文の詳細を見る

• Two new species of Spiochaetopterus (Chaetopteridae: Polychaeta), S.sanbanzensis, from Sanbanze, off Ichikawa and Funabashi Cities, Tokyo Bay, and S.izuensis from the shallow waters of Sagami Bay, were described. The most obvious difference is the number of segments in region A:9 in S.sanbanzensis and 10 in S.izuensis. In addition, Spiochaetopterus sanbanzensis has elliptical light brown or blackish eye-spots, asymmetrical cordate specialized A4 chaetae, and a color pattern consisting of many dispersed brown spots on both ventral and dorsal faces of region A. In Spiochaetopterus izuensis, a brown band extends from each eye-spot to the level of the A1 chaetae; the convex ventral edge of the head of the specialized A4 chaeta has an oblique section and the color pattern of the body is absent. A comparison is established between these two new species and other known species from Indo-Pacific Ocean
