Remarks: The new species is included in the genus Hawaiioscia since all the most important characters (number and position of noduli laterales, maxillular teeth, penicil on maxillipedal endite,
uropod and shape of male pleopod) correspond to the definition of that genus (see diagnosis in Taiti & Howarth 1997).

These molecules orchestrate coordinated cytoskeletal reorganizations by generating different structures, like filopodium, lamellipodium, or
uropod, depending on the type of GTPase activated, that is, Cdc42, Rac, or RhoA, respectively [29].
ADAM8-dependent cleavage at the
uropod loosens the initial binding and facilitates leukocyte migration [101-103].
Body length was measured from the anterior part of the head capsule to the posterior part of the
uropod by using an ocular micrometer on a LEICA MZ 125 stereo-microscope.
kerathrus individuals were molt staged by microscopic examinations of the
uropod setae according to [31].
First leg, second leg, and
uropod with setae elongated downwards are observable compared to nauplii II stage (Figure 3(c) ii, iii, and iv).
Neutrophils polarize their cytoskeleton to form a leading edge (lamellipodia or pseudopod) towards the signal of origin and a trailing
uropod in the posterior of the cell.
Characters such as
uropod articulation and relative pereonite length have been shown to vary considerably according to developmental stage (Larwood 1940; Masunari 1983; Larsen 2005; Bamber 2010), in this genus as well as amongst other tanaids (Larwood 1954; Bird 2008).

Besides that, the examined material presents some other morphological variations: gnathopod 1 basis 4x longer than wide, versus 3.6x longer than wide in the holotype, and propodus with palmar corner more projected and subacute than in the original description; pereopod 4, coxa 1.4x longer than wide, being this ratio 1.25x in the holotype; pereopod 7, anterior margin of basis 1.7x longer than the basis width, versus 1.5x longer than the basis width in the holotype; and
uropod 3 outer ramus 2.3x the peduncle versus 1.6x in the original description.
The
uropod is distally tapering, and its flagellum is about the same size as the uropodal ramus.
