Description
Size: Length 1.62-2.38 mm (male), 1.7-2.72 mm (female).

Female: The proportional lengths of the cephalothorax and abdomen are as 32 to 13, so that the abdomen is contained 2.46 times in the length of the anterior region of the body. The anterior end of the cephalon slopes downwards to the base of the rostrum and below this bears a double prominence, of which the lower carries two small hairs; the rostral spines are directed downwards and backwards. The 4th and 5th thoracic segments are fused together and the posterior thoracic margin is rounded. The pigment-knob may be situated on either the right side or the left.
The abdomen consists of three free segments with the furcal rami.
The genital segment presents a uniform rounded genital swelling on its ventral aspect. The anal segment and the furcal ramus are of the same length. The furcal ramus bears five setae, of which the outermost arises from the lateral margin about half-way along its length.
The 1st antenna reaches back nearly to the posterior margin of the genital segment; it consists of twenty-two free joints. The proximal segment, as usual, consists of the 1st and part of the 2nd segment fused together; segments 7 to 11 are fused into a single solid piece.
The distal end of the first joint bears a single spine. The 2nd segment bears a single spine directed distally; segment 3 has no spine and segment 4 bears a single small spine. Segment 12 and 13 are partially fused.
In the 1st swimming leg the 2nd basal segment bears the usual spinous process on its posterior aspect. Each ramus consists of three segments.
Male: Button on right hand side. Symmetrical abdomen. Divergent furca.
