Abstract
|
|
|
|
Ovigerous crabs of Erimacrus isenbeckii were collected from the northeastern coast of South Korea and their larvae were reared in the laboratory. Two zoeal stages were described and illustrated in detail. The first zoeal characteristics between the present material and Sasaki and Mihara's (1993: J Crust Biol. 13:511?522) were different especially in the setations of the endopods of the maxillipeds. The zoea of Erimacrus isenbeckii strongly resembled those of two Telmessus species in the Cheiragonidae, but the former could be distinguished from the latter by having spinulate carapace spines, a lateral process on the abdominal somite 3, and longer lateral spines on the telson fork.
