A poorly known scorpionfish, Neomerinthe pallidimacula, previously known only from the holotype, is redescribed on the basis of the holotype from the Philippines and an additional specimen from the Wallis and Futuna Islands. This species is distinguished from its congeners in the Indo-Pacific Ocean by having a ventrally directed anterior lacrimal spine, the posterior margin of the maxilla reaching to a vertical through the posterior margin of the orbit, a well-developed symphysial knob, a well-developed upper posttemporal spine, a slit behind the fourth gill arch, 18-20 pectoral-fin rays, the pectoral-fin membranes between the middle and lower rays deeply incised, 44-45 scale rows in longitudinal series, and three slightly curved brownish white or white stripes on the lateral surface of the trunk in preserved specimens, and in lacking the lateral lacrimal and second preopercular spines.
