Abstract

    Spiny lobsters Panulirus spp. of the family Palinuridae Latreille, 1802 occupies the shallow tropical and subtropical waters (<100 m depth). These species are ubiquitous and abundant, yet knowledge of its range, biodiversity, and population abundance in Malaysia is limited. Panulirus homarus is listed as “Least Concern” along with other 11 species out of 21 spiny lobster species in the International Union for Conservation of Nature and Natural Resources (IUCN) red list in 2022. A total of five species were reported from Malaysia waters. Whilst, this study reports the sixth spiny lobster species, Panulirus homarus homarus, with morphology and molecular genetic information (Cytochrome oxidase I (COI) gene) provided. The p-distance within P. h. homarus was 0.2 – 0.6%, n = 12; between P. h. homarus with P. h. rubellus and P. homarus “Brown” was 6.4 – 6.8%, n = 12 and 0.8 – 3.3%, n = 12, respectively. Intra-species p-distance within Panulirus spp. was below 3%, while inter-species was above 10%. This validates the collected specimen as P. h. homarus and P. h. rubellus is the subspecies, but leaving P. h. “Brown” taxonomic status unclear. Thus, genetic information is important in solving many of these systematic and taxonomic problems, because often these species are difficult to distinguished based on morphological criteria. A key to all Panulirus spp. identified in Malaysia waters was constructed. This study updates the marine biodiversity list in Malaysia, where the acquisition of biological knowledge is vital to the protection of the world’s natural resources as well as to the sustainable management of spiny lobster fisheries.
