Abstract
The complete larval development of Allogalathea elegans (Adams & White, 1848) is described and illustrated from laboratory-reared material. This species has four zoeal stages and one megalop. Diagnostic zoeal characters of the genus Allogalathea are compared with those of the other galatheid genera for which the larval morphology is known. Zoeas of A. elegans are readily distinguished from those of other galatheids by the combination of setation of the maxillular and maxillar endopods. Megalopal morphology of A. elegans is remarkably different from those of the two sympatric galatheids, Galathea amboinensis and G. inflata, in dentition on the lateral margins of the rostrum and carapace.
