A total of 10 isopods consist of adults and juveniles stages (ranging from 3 to 8 mm) were examined under scanning electron microscope (SEM). Results showed that the cephalon consists of the first segment of the thorax fused to the head, two pairs of antenna with a large and well-developed pair of compound eye and a mouth. Both antennae were well developed with peduncle and flagellum clearly differentiated. The molar process of mandible is greatly reduced and the mandibular incisor narrow. The maxillule is generally hooked or with one or two terminal spines while maxilla is short and tiny. The maxilliped palp was observed with two to five articles and has sparse setae. Pereopods IIII are weakly prehensile and pereopods IVVII ambulatory. The abdomen consists of five pleonites plus pleotelson. Each of the pleonite has a pair of biramous pleopods while the pleotelson consists of biramous uropods. The species was identified as Corallana nodosa Schioedte & Meinert, 1879, agreeing well with the original description.
