Description of adults
Size (mm). Body length: „ 2.38, ♀ 2.28, 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 8A View Figure 8 ). Antennule six-segmented, setation as in K. gigantea .
Antenna ( Figure 8B View Figure 8 ). Antenna two-segmented, setation as in K. gigantea .
Labrum ( Figure 8C View Figure 8 ). Labrum flat, with two terminally denticulated median teeth flanked by 10 main and one or two additional teeth on both lateral sides.
Mandible ( Figure 8D View Figure 8 ). Mandible as in K. gigantea except the incisor process of three teeth.
Maxillule ( Figure 8E View Figure 8 ). Maxillule two-segmented, ornamentation as in K. gigantea except that the three simple setae on outer distal margin of the distal segment exceed the base of the terminal claws.
Maxilla ( Figure 8F View Figure 8 ). Maxilla four-segmented. Second segment half fused with third segment; setal formula 2-4-15-1.
Thoracopods I–VII ( Figures 8G, H View Figure 8 , 9A–C View Figure 9 , 10A, B View Figure 10 ). Thoracopods I–VII as in H. gigantea except the following. Exopodite of thoracopods I–VII with two terminal setae and with one seta 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 8I View Figure 8 ) hemispherical in lateral view. Protopodite massive, with two hooks on inner margin. Penial region protruded. Epipodite absent. Basipodite without seta, inner margin of basipodite drawn out into projection.
Exopodite triangular, bearing one seta. Endopodite as large as exopodite, denticulated terminally. Thoracopod VIII of female ( Figure 8J View Figure 8 ) in form of two tiny cones with spikes.
First pleomere. First pleomere with a pair of setae.
Uropod ( Figure 9E View Figure 9 ). Uropod bearing 14 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 setae, one lateral seta and one ventromedian seta. Outer one of both terminal setae twice as long as somewhat thicker inner seta.
Pleotelson ( Figure 9E, E View Figure 9 ). Pleotelson with one seta at base of furcal rami on both sides. Anal operculum flat, protruded slightly.
Furcal rami ( Figure 9D, E View Figure 9 ). Furcal rami 1.2 times as long as wide, with five spines and with two dorsal plumose setae.
