Abstract: The first stage zoea of the anomuran chirostylid crab Chirostylus ortmanni Miyake & Baba, 1968, is described and illustrated. Many characters, when compared with the typical zoeal development of Galatheoidea Samouelle, 1819, have appeared at a much earlier stage, including the antennule endopod; mandibular palp; well-developed pereiopods and biramous third maxilliped, biramous pleopods and a sixth abdominal somite. The presence of all these characters suggests that the zoeal phase for this species is abbreviated prior to metamorphosis to megalop. In addition, the setal armature on the coxal, basial and endopodal segments of the maxillule, maxilla and first two maxillipeds is absent, indicating that the first stage zoea of C. ortmanni is lecithotrophic. The zoeal morphology of the mouthparts is compared with other known reports of lecithotropic brachyuran and anomuran larvae, and abbreviated zoeal development in association with yolk feeding is discussed. © National University of Singapore.
