Description. MALE. Body (Fig. 6). Observed length 1.8–4.0 mm; body slender, about ten times longer than broad; cephalothorax frontal margin straight from eye to slight rostrum, lateral margin straight-sided for about one third distance from eye, then expanded in smooth convex curve to anterio-lateral corner of pereonite-1, length about 1.2 times width and approximately one-sixth body length; eyes pear-shaped, about one-fifth length of cephalothorax. Pereon just over half total length; pereonite-1 length about one-quarter width; pereonites 2 and 3 similar, about 1.5 times length of pereonite-1, length about one-third width; pereonites 4 and 5 about 1.6 times length of pereonite-3, length about half width; pereonite-6 about 1.1 times length of pereonite-3, length about one-third width.
