  • Parasesarma bidens(De Haan, 1835) has been designated as a marine protected species by the Act on conservation and management of marine ecosystems. This crab has been recorded only from Jeju-do and Geomun-do, Republic of Korea. In this study, we describe for the first time the mitochondrial cytochrome c oxidase subunit I(COI) sequences of P. bidens. The intra-specific genetic distance among the Korean populations and between the Korean and Chinese populations ranged from 0% to 0.9% and 1.9% to 2.7%, respectively. The inter-specific genetic distances among the four Parasesarma species ranged from 10.9% to 12.8%. The finding of this study will be helpful to better describe P. bidens using COI DNA barcodes and can be used as basic data for their restoration and conservation research.

  • The complete larval development of Chiromantes haematocheir was obtained by laboratory rearing. Five zoeal and one megalopal stages are described and illustrated in detail. Morphological characteristics of the larvae slightly differ from those of Lee (1988), especially in the setal presence of mouthpart appendages. Seven sesarminid zoeas (Parasesarma acis, Parasesarma pictum, Perisesarma bidens, Sesarmops intermedius, Chiromantes dehaani, Chiromantes haematocheir, and Nanosesarma gordoni) can be distinguished from each other in characters of the carapace spines, the antennal exopod and the fork of telson. A provisional key is first provided to aid the identification of seven sesarminid zoeas in Korea.
