The inner marginal spine arises from about the middle of the distal segment. The spine is rather coarsely serrated on anterior margin and the teeth arranged in a slightly twisted line. Outer marginal spine small, located just to the opposite to the inner marginal spine. A specimen (4.07 mm) had the P5 furnished with usual spines, 1 small spine at the base of the apical spine (fig.i). Nota Male: - Cephalothorax about 2.22 times the abdomen length. - 4th and 5th thoracic segments with trace of articulation in lateral view. - Rostrum as in the female. - Abdominal segments and caudal rami in the proportional lengths 12 : 38 : 20 : 23 : 2 : 5 = 100. - 2nd to 4th abdominal segments fringed with fine teeth on distal margin. - Caudal rami divergent, as long as wide. - A1 20-segmented on right side, extends about to the end of cephalothorax. - A2 exopod 1.3 times as long as endopod; exopodal 1st segment furnished with short hairs on anterior proximal corner. - Md with a robust 2nd basal segment. - Mx1 as in female. - Mx2 with 3 long vermiform and 5 amalliform sensory filaments on distal segment; the 5th lobe with a long and strong spine (fig.k). - Mxp with basal segments more robust than those of the female; - P1 with outer edge spine on the 1st exopodal segment slender, reaching the base of the outer edge spine of the 2nd segment. - P2 with the outer edge spine on the 1st exopodal segment reaches the middle of the outer margin of the 2nd segment, and slightly curved; terminal spine of exopod with 48 teeth, the spine makes fenestella. - P3 with the terminal spine of exopod provided with fenestella. - P5 resemble to that of Scolecithricella gracilis Sars, 1905 (= Amallothrix gracilis Sars, 1925) but much shorter, reaching back to the middle of the 3rd abdominal segment. Endopod of the right leg short and furnished with a small spine at apex; exopod and endopod of left leg are subequal in lengths; terminal segment of exopod furnished with a small spine at apex and comb-like hairs on the inner margin. Distal segment of exopod of right leg lancet-form (fig.m).
