crabs (Brachyura: Ocypodidae: Gelasiminae) in Taiwan consist of 5
genera and 15 species, but knowledge of their larval development is
limited to just 3 species, namely Austruca lactea, Tubuca arcuata, and Xeruca formosensis.
In our study, the morphology of the first zoeal stage (zoea I) of the
15 species is described and compared to previous studies. The results
show that the characters of zoea I can be used
to distinguish the five studied genera and most species (except three groups, “Gelasimus borealis, G. jocelynae and G. vocans”, “Paraleptuca crassipes and P. splendida” and “Tubuca arcuata, T. coarctata and T. paradussumieri”).
The lateral spines on the carapace in zoea I are suggested to be a
unique character in the Ocypodinae because they are absent in the
Gelasiminae and Ucidinae, which supports the current
systematics of the Ocypodidae.
