Abstract

Two new species of Melitoid amphipods from Pulau Perhentian Besar and Pulau Tinggi, east coast of Peninsular Malaysia were described and illustrated. Specimens were collected by means of an airlift suction sampler at seagrass areas of the two islands. Ceradocus mizani sp. nov. found commonly at seagrass areas of Malaysian waters, can be readily distinguished from any other known Ceradocus species by a set of distinct characters based on the asymmetrical male gnathopod 2; sculpturing on the palm of the larger gnathopod 2; serrated pleonal epimeron 1-3; and multidentate dorsal pleonites and urosomites with 11 spines on urosomite 1 and 6 spines on urosomite 2. Victoriopisa tinggiensis sp. nov. on the other hand is characterized by its prolonged lateral cephalic lobe; the presence of an anteroventral notch on the head; weakly developed eyes; and pereopod 7 basis with intermediate lobation. This would be the first record of the genus Ceradocus and Victoriopisa from the waters of Peninsular Malaysia. Discovery of these two new species represents an ongoing and continuous effort on amphipod taxonomical studies here in Malaysia.
