Abstract

The complete larval development of Gecarcinus lateralis lateralis (Fréminville, 1835), a gecarcinid land crab from Bermuda, is described and illustrated based on larvae reared in the laboratory. The species passes through six (possibly five) zoeal stages and one megalopal stage. The development through six zoeal stages to the young crab stage takes at least 29 days. Morphological characters of G. l. lateralis larvae are compared with gecarcinid species of which the complete larval development is known, i.e., Cardisoma guanhumi and C. carnifex. /// Description du développement larvaire de Gecarcinus lateralis lateralis, un crabe terrestre de Bermuda, cultivé en laboratoire. L'espèce est caractérisée par six (ou cinq) stades zoé et une mégalope, qui sont décrits et figurés. Le développement larvaire depuis l'éclosion jusqu'au premier stade crabe, dure au moins 29 jours. Les caractères morphologiques sont comparés avec d'autres espèces des Gecarcinidae, dont le développement complet est connu, i.e., Cardisoma guanhumi et C. carnifex.
