[Two new species of goneplacid crab, Goneplax marivenae and G. megalops, are described from the Philippines and Japan, respectively. Both new species are closely similar to G. sigsbei (A. Milne-Edwards, 1880) from the western Atlantic Ocean in the form of the carapace, eyestalk, fourth ambulatory leg, and male pleopods, but can be distinguished from G. sigsbei by the form of the orbit. Both new species are also similar to G. maldivensis Rathbun, 1902, but are distinguished from G. maldivensis by the form of the male abdomen. Goneplax marivenae is most closely similar to G. megalops, but can be distinguished from G. megalops by the form of the extraorbital tooth and the male first pleopod.

Les deux especes nouvelles sont tres proches de G. sigsbei (A. Milne-Edwards, 1880) de l'ocean Atlantique occidental par la forme de la carapace, les pedoncules oculaires, la quatrieme patte ambulatoire, et les pleopodes mâles, mais s'en distinguent par la forme de l'orbite. Les deux nouvelles especes ressemblent egalement a G. maldivensis Rathbun, 1902, mais s'en distinguent par la forme de l'abdomen mâle. Goneplax marivenae est le plus proche de G. megalops, mais en differe par la forme des dents extraorbitales et le premier pleopode mâle. , Two new species of goneplacid crab, Goneplax marivenae and G. megalops, are described from the Philippines and Japan, respectively.
