Figures

Plate 1 issued from : S. Ohtsuka, G.A. Boxshall & H.S.J. Roe in Bull. nat. Hist. Lond. (Zool.), 1994, 60 (2). [p.132, Fig.16, B,H].
Female (from Canary Is.): B, genital double-somite (ventral); H, praecoxal arthrite, coxal and endopod of Mx1 (endopod indicated by arrowhead). cd = copulatory duct; cp = copulatory pore; g = gonopore; rd = receptacle duct; o, oviduct; s, spermatothore remnant; sr = seminal receptacle.
Scale bars in mm.
Nota: Genital double-somite similar to that of A. plumifer, but distinguishable since seminal receptacle relatively much larger than in A. plumifer, over half length of genital double-somite. Endopod of Mx1 distinctly 1-segmented, bulbous with 1 bipinnate seta.
