Larvae and juveniles of six species of Luciogobius were collected at Aritsu Beach on Okinawa Island using a small seine. Postflexion larvae were dominant during sampling and were collected when they approached the shoreline adjacent to or at the entrances to their adult habitats prior to settlement. Standard lengths of postflexion larvae ranged from 5.4 to 14.4 mm and varied depending on the species. The larvae occurred mainly from January to April, but some larvae were caught in October and November. Their pelagic larval durations were estimated to range from 17 to 36 days and varied depending on the species. Morphologies of field-caught larvae and juveniles and laboratory-reared juveniles were described. Six species were clearly distinguished based on fin ray and vertebral counts, proportions, body size, and pigment patterns. Although their taxonomic statuses could not be determined, it is thought that they have independent relatives in other regions.
