The taxonomy of the pilumnid crab genus Lophoplax Tesch, 1918, is discussed. Lophoplax sculpta Stimpson, 1858) is redescribed and a neotype is selected in the interests of nomenclatural stability. Two new species allied to L. sculpta are described: L. sordida n. sp. from Indonesia, and L. pannosa n. sp. from Vanuatu. Pilumnus vermiculatus A. Milne-Edwards, 1873, is here transferred to Lophoplax. The poorly known Pseudocryptocoeloma parvus Ward, 1936 (type species of Pseudocryptocoeloma Ward, 1936), known only from Australia thus far, is redescribed and figured; and Pseudocryptocoeloma symmetrinudum Edmondson, 1951 (from Samoa and Japan), is transferred to Lophoplax.
