Numerous gland pores along entire pereonites margin. Pereonite 1 with rounded postero-lateral corner, posterior margin nearly straight. Noduli laterales on pereonites 1–4 much farther from lateral margins than those on pereonites 5–7. Telson triangular, with slightly concave on lateral margins, posterior apex pointed; uropodal exopod ~ 1.5–2 × as long as protopod; protopod with an incision on the outer margin (Figs
