Resumen:
The different stages of embryonic development of the porcellanid crab Pachycheles chubutensis are described,along with the chronology of each stage at 16 +8 Five different developmental stages (I V)were recognized including:(i)early cells and 100%of the vitellum;(ii)formation of the embryonic primordium at the animal pole of the egg;(iii)presence of dark pig- mentation on the posterior part of the ocular globe;(iv)appearance of chromatophores on mouth parts and in the abdominal zone;and (v)eye pigmentation in circular oval form,filling the entire surface.The embryonic development lasts from spawn- ing to hatching approximately 21 days,with the second stage being the longest.
