Holotype: „ dissected on five slides, Weber Plains , East Kimberley, Western Australia, Australia, OIA bore WP 19 (15 ° 239390S, 128 ° 579050E), BES 6356, 12 August 1998, S. M. Eberhard leg. coll. Western Australian Museum, Perth ( WAM C 34247). Allotype: ♀ dissected on four slides, same data as for holotype except OIA bore WP 11 (15 ° 279310S, 128 ° 549080E), BES 6355 ( WAM 34248). Paratypes: 1 „ on a slide, same data as for holotype except OIA bore WP 9 (15 ° 269210S, 128 ° 559100E), BES 6359 ( WAM C 34249).
Etymology
The species is named after the Kimberley region, where the species was collected.
Description of adults
Size (mm). Body length: „ 2.05–2.09, ♀ 2.19, approximately 10 times as long as wide. Head as long as length of segments 1–4. The female differs from the male only in thoracopod VIII.
Antennule ( Figure 6A View Figure 6 ). Antennule six-segmented, setation as in K. gigantea .
Antenna ( Figure 6B View Figure 6 ). Antenna two-segmented, setation as in K. gigantea .
Labrum ( Figure 6C View Figure 6 ). Labrum flat, with two terminally denticulated median teeth flanked by seven main and six additional teeth on both sides.
Mandible ( Figure 6D View Figure 6 ). Mandible as in K. gigantea except the incisor process of three teeth.
Maxillule ( Figure 6E View Figure 6 ). Maxillule two-segmented, ornamentation as in K. gigantea .
Maxilla ( Figure 6F View Figure 6 ). Maxilla four-segmented. Second segment half fused with third segment; setal formula 2-4-15-1.
Thoracopods I–VII ( Figures 6G–I View Figure 6 , 7A–D View Figure 7 ). Thoracopods I–VII as in H. gigantea except following. Exopodite of thoracopods I, V, VI, VII with two terminal setae and with one seta on inner margin. Exopodite of thoracopods II–IV with two terminal setae and with two setae on inner margin. Setal formulae of endopodite of thoracopods I–VII: thoracopods I: 1+0/2+1/1+0/3(1); thoracopods II–IV: 0+0/1+1/0+1/2; thoracopods V–VII: 0+0/0+1/0+1/2.
Thoracopod VIII. Thoracopod VIII of male ( Figure 6J View Figure 6 ) hemispherical in lateral view. Protopodite massive, with two hooks on inner margin. Penial region slightly protruded. Epipodite represented by a tiny hemisphere. Basipodite without seta, inner margin of basipodite drawn out into projection. Exopodite triangular, bearing one seta. Endopodite 50% of exopodite, denticulated terminally. Thoracopod VIII of female ( Figure 6K View Figure 6 ) in form of a bifurcated structure resulting from the basal fusion of left and right thoracopods. Distal end of each branch sharply pointed.
First pleomere. First pleomere with a pair of setae.
Uropod ( Figure 7F, G View Figure 7 ). Uropod bearing 14–15 spines on inner distal margin of sympodite. Distal spine twice as long as proximal spines of equal size. Endopodite 30% as long as sympodite, drawn out distally into slightly curved spur, with two setae at base of spur and one further subterminal seta on outer margin. Exopodite as long as endopodite, with two terminal and two lateral setae and one ventromedian seta. Outer one of both terminal setae twice as long as the somewhat thicker inner seta.
Pleotelson ( Figure 7E, F View Figure 7 ). Pleotelson with one seta at base of furcal rami on both sides. Anal operculum flat, concave.
Furcal rami ( Figure 7E, F View Figure 7 ). Furcal rami 1.5 times as long as wide, with five spines and with two dorsal plumose setae.
