 issued from : A. Scott in Siboga-Expedition, 1909, XIX a. [Plate XLIV, Figs.4-7]. With doubt (perhaps juvenile). Female (from Halmahera Sea): 4, habitus (dorsal); 5, forehead (lateral); 6, last thoracic and genital segments (left side); 7, P5.

 issued from : C.B. Wilson in Bull. U.S. Natn. Mus., 1950, 100, 14 (4). [Pl.4, Figs.23-26]. As Arietellus armatus. Female (from 8°04'N, 52°04'N): 23-24, habitus (dorsal and lateral, respectively); 25, P5. Nota: Endopod of A2 a little longer than exopod. Md palp uniramose with endopod entirely lacking. Genital segment wider than long and not protruding ventrally, with nearly straight sides. Anal segment incised posteriorly. Caudal rami at the corners of the anal segment and divergent, each a little longer than wide and with 5 stout setae, the 3 middle setae much longer than the other two, plumose, the outer seta at the middle of the outer margin. P5 uniramose and 3-segmented; their basal segments fused across the midline, the two plumose setae on the inner corners of the 2nd segments and the appendicular filiform seta on the right leg exceptionally long; the 3rd segments are nearly as long as the other two combined, slightly swollen at the base and tapered into long acuminate points. Male: P5. Nota: Left A1 geniculate. P5 asymmetrical, the right one longer and stouter than the left, with two curves giving it an S shape; the first two segments of exopod with spines at their outer distal corners, long, slender and acuminate; the 2nd segment also has a short and stout spine on the surface at the distal end just inside the inner margin; the terminal segment is nearly 3 times as long as wide, bluntly rounded at its tip and without any spines or setae; right endopod apparently 2-segmented and attached to the inner margin of the basipod near the distal end. The first two segments of the left leg also carry spines at the outer distal corner, stouter than those on the right leg and slightly curved, and in addition the 2nd segment has a sinuous distal margin; the terminal segment is armed with 3 fingerlike processes, 1 on the outer margin near the base and 2 unequal in size at the tip; the left endopod is 1-segmented, and its enlarged tip is bilobed; like the right endopod, it is attached not to the end of the basipod but on the inner margin.
