An updated comprehensive checklist of polychaete species, which have been recorded from Malaysian waters, is provided, with their geographic distributions and the research history for them. A total of 57 species belonging to 30 families have been reported since the early 1870s, with Nereididae as the most dominant family with ten species; however, more than half of the total are questionable species in the country. Despite the increased efforts of polychaete studies in the past decade, the taxonomic endeavour of discovering and describing species in the country could be higher. Malaysian polychaetes were mostly recorded from Peninsular Malaysia, whereas very few were from Borneo Island. Most previously recorded species were associated with intertidal and estuarine habitats and a few were found in the subtidal and freshwater environments. We stress the need for urgent research on this biologically, ecologically and culturally relevant taxonomic group as the species accumulation curve grows exponentially in this megadiverse country.
The current checklist has been updated since the previous one in 2013. Many species previously listed were judged as doubtful and not taxonomically reliable.

Polychaetes are predominantly marine, with some species inhabiting fresh and terrestrial groundwaters (
Malaysia is one of the world’s megadiverse countries (

Here, an updated checklist of Malaysian polychaetes is provided, re-evaluating the previous checklist and adding current information.
Previous taxonomic and ecological papers (until 2022), in which Malaysian polychaetes were identified to the species level by taxonomic specialists with or without descriptions of specific characteristics, were analysed. In the cases where records were tentatively treated at genus level in literature, only those with taxonomic remarks were here included (e.g. Prionospio sp. in

A bathymetry distribution map of species was constructed using ArcGIS 10.8 and the bathymetry data provided by the General Bathymetric Chart of the Oceans (GEBCO). The bathymetric information of the polychaete was arranged by a 10 m depth interval. The distribution was shown by the following five habitat zones: estuary, intertidal, subtidal, freshwater and unknown zones (Suppl. material
History of polychaete research in Malaysia
The earliest studies of polychaetes in Malaysia began with scientists of different nationalities before the independence era (the 1950s). The first study focused on polychaetes at the Strait of Malacca, considered as one of the busiest shipping lanes in the world, following behind the Dover Strait back in those days (
There were expeditions in the IMPA (Indo-Malay-Philippines Archipelago) or the Malay Archipelago (
Various national and international research studies were undertaken in the early 1960s up to recent years (Table

A total of 57 species belonging to 47 genera in 30 families of polychaetes were recorded from Malaysian coastal waters; 53 species were recorded from Peninsular Malaysia, three species from Borneo and one species from both geographical regions. Amongst them, ten species (17% of total) were originally described from Malaysia, whereas the presence of other 30 (53%) species is questionable.
The bathymetric information (Fig.
The topmost species-rich polychaete family is Nereididae, with ten species (Table
Studies on marine annelids were mainly done by international scientists and through collaborations. Most local researchers focused on ecological and diversity studies. Over the past decades, few taxonomy studies were published particularly by Malaysian taxonomists (
A total of 57 species of Malaysian polychaetes has been reported since 1866 until 2019. This current checklist included species from the previous one (
More studies on polychaetes in Malaysia need to be carried out, mainly related to identifying and describing species. Additionally, there should be follow-up studies on several previous research to validate the species recorded in ecological and environmental studies.
The presence of polychaete species considered to be widely distributed or cosmopolitan in Malaysian coastal waters has not been previously considered by this study. It is estimated that, of the total number of polychaete species recorded in Malaysia (57 species), approximately 53% (e.g. Notomastus latericeus, Spiochaetopterus costarum, Cirriformia tentaculata) require a detailed revision since some may belong to cryptic or pseudocryptic species (
International collaborations may help expand polychaete taxonomic research in the country. For instance, the involving of international and local polychaete taxonomists in identifying species and depositing biological materials in domestic and internationally recognised collections for future studies (
In Malaysia, there is a need for more to be done in polychaete research. More studies on polychaete systematics, genetics, ecology, physiology and reproductive biology are urged to be undertaken. Acknowledging this taxonomic group as a vital member or the ‘keystone’ in the ecosystem is also essential. Their feeding behaviour, metabolic activities and distinct characteristics while modifying their habitats and surrounding made them known as the ecosystem engineer (

Contains species listed in the checklist with remarks of species with type locality in Malaysia and species that were originally described outside of the Central and Western Indo-Pacific. The species that were listed in the latter were regarded as questionable species. Information on the repository and voucher materials of species were listed. On a seperate sheet is a list of species that were excluded from the previous checklist by Idris and Arshad (2013).
Contains the occurrences of the species with their location, depth and habitat. These data have been used to construct the bathymetry distribution map.
