Larval Development of Latreutes acicularis Ortmann (Crustacea: Decapoda: Hippolytidae) Reared in the Laboratory

摘要

Eight zoeal stages and one decapodid of the hippolytid shrimp Latreutes acicularis Ortmann, 1890 are described from laboratory-reared material hatched from egg from ovigerous females collected from Shimoda, Japan. The presence of a minute dorsomedianprotuberance on the third abdominal somite, the spinules on the dorsal margin of the fourth and fifth abdominal somites, and a pair of dorsolateral spines on the fourth and fifth abdominal somites readily distinguish the larvae of L. acicularis from those of L anoplonyx Kemp, 1914 and L laminirostris Ortmann, 1890, the other two known larvae of Latreutes from East Asia.
