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.

The first zoeal characters of Sesarmops intermedius (De Haan, 1835) [=Sesarma (Sesarma) intermedium], belonging to the family Sesarmidae, are described and illustrated in detail based on laboratory-hatched material from a female collected from Gangjeung, Seogwipo, Jeju Island. Morphological comparison is performed based on previous descriptions of Sesarma (Sesarma) intermedium from Japan and three other species in the Sesarmidae. The first zoea of Sesarmops intermedius can be readily distinguished from those of the three species Chiromantes haematocheir [=Sesarma (Holometopus) haematocheir], Chiromantes dehaani [=Sesarma (Holometopus) dehaani], and Parasesarma pictum [=Sesarma (Parasesarma) pictum] by the presence of two setae on the exopod of the antenna, fine setae on the inner and outer margin of the forked spine of the telson, and three aesthetascs and one simple seta on the antennule.
