. Eyes rounded, large and protruding, 0.36 of lateral length of cephalothorax. Body long, slender, pereonite 1 fused with head; dorsal transverse ridge between cephalothorax and pereonite 1. Preocular spines absent; supraocular spines long, slender and directed anteriorly, unarmed, not covering the eyes in dorsal view, about 3.0 times as long as diameter of eye. Further dorsal spines are lacking. All pereonites unarmed, with rough cuticle. Pereonites 1–3 of about same length and width; pereonite 4 longest, slightly narrower than pereonites 1–3, of about the same width as pereonites 6–7; pereonite 5 slightly longer than pereonites 4 and 6–7. Tergites of pereonites 5–7 with concave posterior border into which the following segment fits when the animal bends dorsally.
