Figures
Plate 1 issued from : J.M. Bradford in N.Z. Jl Mar. Freshw. Res., 1969, 3 (4). [p.501, Figs 199-215]. Female (from NE New Zealand: E North Cape): 199, left A1; 200, habitus (lateral right side); 201, right A1; 202, rostrum; 203, habitus (dorsal); 204, urosome (dorsal); 205, idem (lateral right side); 206, P1; 207, P2; 208, P3; 209, A2; 210, Md (mandibular palp); 211, P5; 212, Md (cutting edge); 213, Mx1; 214, Mxp; 215, Mx2.
Nota: Rostrum bifurcate A1 23-segmented, unequal, left longer. Mx1 with 11 spines and setae (13 in paratype) on inner lobe 1, 1 on inner lobe 2; endopod fused with basis and carrying 1 short spine; exopod with 6 setae. No seta on outer lobe 1. Mx2: first 3 lobes with 4, 2, 1 setae respectively; lobe 4 with large spine-like seta which lies parallel to following segment for part of its length; segment carrying lobe 5 elongate, bearing 2 spine-like setae; 7 spines and setae on remainder of limb..
Plate 2 Issued from : J.M. Bradford-Grieve in The marine fauna of New Zealand. Nat. Inst. Water Atm. Res. Biodiversity Memoir 111, 1999. [p.20, Fig.6]. Female: A-B, habitus (lateral and dorsal, respectively); C, rostrum; D, left A1; E, A2; F, Mx1; G, Mx2; H, Mxp; I, P5.
Nota: Left posterior corner of last thoracic segment extends further posteriorly than right. Urosome 0.2-0.25 times the length of prosome. Genital segment hardly swollen. Right A1 extends to middle of pedigerous segment 1, longer on left. A2 exopod 6-segmented. Md palp with 2 setae on basis; terminal endopodal segment with 3 setae. Mxp with distal region of coxa expanded and covered with small spinules as in opposing part of basis; endopod 4-segmented, last segment small.
Bathypelagic (hyperbenthic). Taken by Bradford (1969 b) at greater than 1200 m on the continental slope off NE New Zealand, where it is deduced to have a benthic habitat. For Bradford (1969 b, p.500), this species differs in several respects from other genera in the Bathypontiidae; of those species which have a female P5 none except Alloiopodus has the exopod of segment 1 of similar shape to that of the other swimming legs. This is the only genus with a very short A1 and with a gripping joint between basipods 2 and 1 of Mxp.
