( Figures 14–16 View Figure 14 View Figure 15 View Figure 16 )
Type material
Holotype: ♀ dissected on five slides, Argyle Diamond Mine , Kimberley, Western Australia, Australia, bore MB 33 S (16 ° 439580S, 128 ° 229390E), BES 9704, 10 October 2002, W. F. Humphreys and R. Webb leg. coll. Western Australian Museum, Perth ( WAM C 34256).
Paratypes: 2♀♀ same data as holotype except bore MB 47 (16 ° 439240S, 128 ° 239360E), BES 9711, 13 October 2002 ( WAM C 34257 and 34258) .
Etymology
The species is named after the setation on pleomeres.
Description of adults
Size (mm). Body length: ♀ 1.56–1.96, approximately 10 times as long as wide ( Figure 14 View Figure 14 ). Head as long as length of segments 1–4. Male unknown.
Antennule ( Figure 15A View Figure 15 ). Antennule six-segmented. Setation as in K. mandorana .
Antenna ( Figure 15B View Figure 15 ). Antenna two-segmented, setation as in K. gigantea .
Labrum ( Figure 15C View Figure 15 ). Labrum flat, with two terminally denticulated median teeth flanked by five main and seven additional teeth on both lateral sides.
Mandible ( Figure 15D, E View Figure 15 ). Mandible as in K. gigantea except the incisor process of three teeth.
Maxillule ( Figure 15F View Figure 15 ). Maxillule two-segmented. Proximal segment with four setae on inner distal margin. Distal segment with two terminal claws, with four claws on inner edge, and with three simple setae on outer distal margin. The three simple setae on outer distal margin of the distal segment exceed the base of the terminal claws.
Maxilla ( Figure 15G View Figure 15 ). Maxilla four-segmented. Second segment half fused with third segment; setal formula 2-4-14-1.
Thoracopods I–VII ( Figures 15H–J View Figure 15 , 16A–D View Figure 16 ). Thoracopods I–VII as in H. gigantea except the following. Protopodite of thoracopods I–VII each bearing one epipodite. 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–VII: 0+0/1+1/0+1/2.
Thoracopod VIII. Thoracopod VIII of female ( Figure 16E View Figure 16 ) in form of a bifurcated structure resulting from the basal fusion of left and right thoracopods. Distal end of each branch blunt.
Pleomeres I–V ( Figures 14 View Figure 14 , 16F View Figure 16 ). Pleomeres I–V each with a pair of setae.
Uropod ( Figure 16H View Figure 16 ). Uropod bearing 11 spines on inner distal margin of sympodite. Distal spine 1.5 times as long and twice as thick as proximal spines of equal size. Endopodite 20% as long as sympodite, drawn out distally into slightly curved spur, with two setae at base of spur. Exopodite as long as endopodite, with two terminal setae and one ventromedian seta. Outer one of both terminal setae twice as long as somewhat thicker inner seta.
Pleotelson ( Figure 16G, H View Figure 16 ). Pleotelson with one seta at base of furcal rami on both sides. Anal operculum flat, protruded slightly.
Furcal rami ( Figure 16G, H View Figure 16 ). Furcal rami 1.2 times as long as wide, with six spines and with two dorsal plumose setae.
