The estuarine panopeid crab Eurypanopeus canalensis Abele and Kim, 1989, is an eastern tropical Pacific species with a known distribution from the southeastern Gulf of California, Mexico, to Panama. Its complete larval development is fully described and illustrated from laboratory-reared material. The four zoeal stages and the megalopa are compared with two congeneric species from the West Atlantic, E. abbreviatus (Stimpson, 1860) and E. depressus (Smith, 1869). The main differences between larvae of E. canalensis and those of these two species include telson setation and the presence/absence of a stout hook-like spine in the megalopae cheliped ischium.
