A new species of the genus Trimma is described. Trimma maiandros n. sp. is characterized by having reduced predorsal scales, usually not crossing the midline; a dark ring around the eye and a dark triangular shaped spot extending ventrally and posteriorly from the eye and dark lines forming a zigzag pattern on the upper half of body; a very shallow interorbital groove and shallow or no postorbital groove; scales present on the pectoral and pelvic fin bases but not on the cheeks or opercles; and an unbranched fifth pelvic fin ray that is 25-50% of the length of the fourth ray. Trimma maiandros n. sp. has been found from numerous localities from Cocos (Keeling) Islands in the Indian Ocean and from Japan, Marshall and Mariana Islands to Samoa and Australia in the Pacific. Considerable geographical variation occurs in coloration and other morphological features, and more than one species may be represented.
