| Abstract | The Sultan Iskandar Marine Park (SIMP) in Malaysia is home to a diverse range of marinespecies, yet many remain underexplored. A new locality in the waters of Peninsular Malaysia is reportedfor one species of caprellid amphipod from the genus Hemiaegina. The present study provides a detaileddescription of Hemiaegina minuta Mayer, 1890 (Amphipoda, Senticaudata, Caprellidae) based on newlycollected specimens from Pulau Besar, Sultan Iskandar Marine Park, Malaysia. The specimens ofH. minuta examined in this study exhibited several distinctive characteristics, namely: 1) the outline of itspereonites which appeared hexagonal in shape when viewed dorsally; 2) body smooth dorsally andventrally with a pair of projections/spines between gnathopod 2; 3) peduncular article 3 of antenna 1 veryshort; 4) gnathopod 1 with a round or blunt proximal projection covered in setules; 5) gnathopod 2 withelongated basis, large propodus with a small proximal tooth/grasping spine with unique U-shaped notch; 6)palm of pereopod 7 with proximal knobs, each provided with a spine followed by a short row of serriformteeth; and 7) abdomen with a pair of biarticulate appendages. The biogeography and habitat preferenceof H. minuta are also discussed. This record increases the number of caprellid amphipods from the Malaysiancoast to 15 species. This new record emphasizes the importance of continued biodiversity assessments inthe region, providing essential data for marine conservation efforts. |
