Female (off Kaikoura, New Zealand): 18, genital segment (lateral right side); 19, forehead (lateral).
Scale bars represent 0.1 mm.


Espèce Undeuchaeta intermedia - Planche 3 de figures morphologiquesissued from : R.B.S. Sewell in Mem. Indian Mus., 1929, X. [p.125, Fig.47]. As Undeuchaeta bispinosa.
Female (from laccadive Sea): a, posterior thoracic margin and the first two abdominal segments (dorsal); b, posterior thoracic margin and urosome (lateral left side); c, A2; d, Mx1; e, Mx2.

Male: a, P1; b, P2; c, P5.

Nota after Conway & al. (2003, p.177): P5 biramous. Right exopodal segment 1 with sharp spine on the first third of the segment, with small projection on opposite side; internal segment covered with almost parallel wavy lines. Left endopodite reaching the distal end of the 1st exopodal segment, 2nd exopodal segment with spine-like projection on external distal border, 3rd exopodal segment proximal angle extending into a spine.


Espèce Undeuchaeta intermedia - Planche 5 de figures morphologiquesissued frm : A. Scott in Siboga-Expedition, 1909, XIX a. [Plate IXXIII, Figs.1-8].
Female (from Indonesia-Malaysia): 1, habitus (dorsal); 2, forehead (lateral); 3, last thoracic and genital segments (left side); 4, idem (right side); 5, rostrum; 6, A1; 7, P1; 8, P2.


Espèce Undeuchaeta intermedia - Planche 6 de figures morphologiquesissued from : C.O. Esterly in Univ. Calif. Publs Zool., 1911, 6 (14). [Pl.26, Fig.4]. As Undeuchaeta bispinosa.
Female (from San Diego Region): 4, habitus (lateral).

Espèce Undeuchaeta intermedia - Planche 7 de figures morphologiquesissued from : C.O. Esterly in Univ. Calif. Publs Zool., 1911, 6 (14). [Pl.29, Fig.48, 56]. As Undeuchaeta bispinosa.
Female: 48, last thoracic segment and genital seggment, showing spermatophore (lateral); 56, genital segment (ventral).
Nota: The genital segment has the hook-like appendage at the right of the orifice, but in addition there is a spine on the right side of the segment about midway between the anterior and posterior borders; there is a 2nd and much shorter spine at the left orifice.; the segment carries a group of heavy spines on the left side at the posterior border, and usually the 2nd segment is similar in that regard.
