The complete larval development ofPanopeus lacustrisDesbonne 1867 (Brachyura: Panopeidae), from the Amazon region, reared in the laboratory

Larvae of the mud crab Panopeus lacustris were reared in laboratory from ovigerous females collected in the estuarine area of the Caete River in the Amazonian region. The complete development of this species consisted of four zoeal and one megalopal stages, which were described and illustrated in detail. The results are compared with those of other previous studies on larval development of the species belonging to the genus Panopeus and then briefly discussed.
