Female (from 126°56.36'N, 33°16.40'E): A-B, habitus (dorsal and lateral, respectively); C, urosome (lateral; arrow indicating ventral ornamentation on 2nd urosomal somite); D, A1; E, A2 (ventral view).
Scale bars in µm.
Nota : Prosome 2-segmented ; about 2.4 times as long as urosome including caudal rami, 3.4 times as long as urosome excluding caudal rami.
Cephalosome completely fused with 1st pedigerous somite, with ventral process, 1.4 times longer than width at base (marked in fig.3 E), 2nd to 4th pedigerous somites forming single compound somite with suture line between 2nd and 3rd pedigerous somites ; 3rd pedigerous somite dorsally covering 4th pedigerous somite, forming inverted triangular shape ; 4th pedigerous somite with extended and pointed posterolateral corners, reaching to 2/3 distance of 2nd urosomal somite, with small protrusions on inner distal margin (arrowed in fig.2A). ).
Frontal part rounded, with 2 large separate cuticular lenses.
Urosome 2-segmented ; proportional lengths (%) of urosomites and caudal rami 7.1 : 66 : 26.9.
1st urosomal somite bearing P5 ventrolaterally (fig.2C), genital double-somite and anal somite combined as 2nd urosomal somite.
2nd urosomal somite (fig.2A-C) distinctly rounded from anterior to mid-region, about twice longer than maximum width at anterior third region, anteroventral margin with patch of minute spinules (indicated by arrow in fig.2C), just rounded without round hump-like projection in lateral view, posteroventral and lateral margiin fringed with minute spinules, posterior margin finely serrated ventrolaterally (fig.2C), dorsoposterior surface almost bearing mucilaginous trace of spermatophore around genital opening (arrowed in fig.2C).
Genital area located dorsolaterally, paired genital apertures approximately 1/3 distance from anterior margin of dorsal surface, hidden behind opercula.
Caudal rami cylindrical, about ¾ of 2nd urosomal somite, 3.3 times longer than wide at base ; each ramus armed with 4 setae : slender anterolateral seta II, outer posterolateral seta III short, spiniform, and serrated along medial margin, inner terminal seta IV longest, and dorsal seta V 2.3 longer than outer seta III and 1.3 times shorter than seta IV.
A1 4-segmented. Proportional lengths (%) of segments measured along posterior non setiferous margin 22.6 : 14.5 : 11.3 : 25.8 : 14.5 : 11.3.
A2 4-segmented, with coxa and basis fused fused and 3 endopodal segments : coxobasis 2.5 times longer than wide, with strong bipinnate seta inner distal margin ; endopod 3-segmented : unequal in length, 1st endopodal segment robust and longest among endopodal segments, about 2.9 times as long as wide at base, bearing bipinnate seta on inner proximal margin, much shorter than coxobasal seta, inner distal margin roughly serrated from 2/3 of margin, with long curved spinous process at ¾ of serrated part, outer lateral margin ornamented row of denticles, naked seta on distolateral margin ; 2nd endopodal segment shortest, bearing 3 elements : curved stout spine arising from outer distal margin, with lateral branch ; slender, pinnate spine located near its base and reaching almot middle of distal spine ; short curved spine arising from inner margin, outer distal spine 1.8 times longer than its branched soine ; 3rd endopodal segment cylindrical, as long as wide and armed with 3 elements : 1 stout terminal spine, short spine arising from inner margin, strong seta on the outer margin, and terminal spine 1.2 times shorter than outer spine on 2nd endopodal segment. Length ratio of terminal spine to outer spine on 3rd exopodal segment 1.5 : 1.
P5 consisting of 2 unequal simple setae located ventrolaterally (fig.2C).
P6 represented by operculum closing off each genital aperture (fig.2A)
