Abstract
The first zoeal stage of Grapsus adscensionis and Planes minutus is de scribed and illustrated. Comparisons are made with known larvae of con generic species and previous descriptions of Planes minutus. Larval fe atures of the Grapsinae are evaluated taking into account all previous larval descriptions from this subfamily. The presence of minute knob- like or hooked projections on the carapace of the zoea I, which in sub sequent zoeal stages develop into lateral carapace spines is proposed as a typical larval feature for subfamily Grapsinae.
