Description
Size: Length: female 0.95-1.07 mm; male 0.82-0.88 mm.

Female: Prosome 4-segmented, and twice as long as the urosome. The outer lateral points at the end of the prosome are short (not reaching the genital openings) and are notched on the inner margin. The inner lateral points are short and pointed at the tip. Urosome 2-segmented. The genital segment has a characteristic shape in lateral view, the antero-ventral angle is almost a right angle, and at the apex there is a small patch of spinules, there is no ventral hook. The genital segment is about 1.5 times longer than the anal segment. Furca about 5 times longer than wide and less than 1/3 the length of the rest of the urosome.
Male: Prosome 4-segmented, and is about 1.5 times longer than the urosome. Segment immediately following the cephalosome has a slight swelling at the central lateral margins. The outer lateral points at the end of the prosome extend 1/3 the way down the genital segment. Urosome is 2-segmented. Genital segment broadly oval with a small ventral hook. Anal segment about 1.5 times longer than wide.
