A checklist of the 870 current valid species of squat lobsters of the world (families Chirostylidae, Galatheidae and Kiwaidae) is presented. The compilation includes the complete taxonomic synonymy and geographical distribution of each species plus type information (type locality, repository and registration number). The numbers of described species in the world’s major ocean basins are summarised. Key words: Crustacea, Decapoda, Anomura, Chirostylidae, Galatheidae, Kiwaidae, checklist, taxonomy Accepted by J. Goy: 29 Jul. 2008; published: 15 Oct. 2008 3 Introduction Crustaceans generally referred to as squat lobsters are members of three families of colourful anomuran deca- pods, the Chirostylidae, Galatheidae and Kiwaidae (Figs 1–4). Squat lobsters share with other Anomura the characteristic presence of five pairs of thoracic legs (pereopods). The first pair is elongate, slender and modi- fied as pincers (chelipeds) and the next three pairs are shorter, simple, walking legs. The fifth pair is much smaller than the others, chelate, folded and usually hidden under the carapace. The general body plan is sym- metrical and the abdomen is depressed. The uropods are spatulate, forming with the telson a broad tailfan, folding up against itself or the thoracic sternum. Adult males usually bear abdominal appendages (pleopods), the first one or two pairs of which are modified into copulatory structures known as gonopods. The first pair of female pleopods is always absent. Squat lobsters are abundant, speciose and distributed worldwide. At the time of writing (May 2008) 870 species of squat lobsters are recognised (Table 1). They occur in all marine habitats, including anchialine caves and hydrothermal vent areas, and at depths ranging from the surface of the sea to more than 5000 m (Baba, 2005). Squat lobsters are primarily found in tropical and temperate waters but are scarce in high lati- tudes. All species are benthic although a few, such as Munida gregaria, can have pelagic juvenile forms (Wil- liams, 1980). Few representatives of these families are economically important. Exceptions include several species from the Eastern Pacific (e.g., Munida gregaria, Pleuroncodes monodon and Cervimunida johni – see Tapella & Lovrich, 2006; Vinuesa, 2007) and off Europe (e.g., Munida intermedia). The ecological impor- tance of squat lobsters, however, is unquestionable. The Galatheidae are exceptionally diverse and include 675 species in 34 genera. The most speciose gen- era are Munida (243 species), Munidopsis (224) and Galathea (70). Most species of Munida are from shelf and slope depths. The majority of species of Galathea live in shallow waters whereas those of Munidopsis are found mainly on continental slopes and abyssal plains. Seventeen galatheid genera are exclusively found in the Pacific Ocean. In contrast, only one genus is found exclusively in the Atlantic Ocean (Anomoeomunida) and one in the Indian Ocean (Nanogalathea). Galatheid species are commonly found living in coral reef, rocky or muddy bottoms. Galatheids are found over the complete depth range of the oceans and in particular are the numerically dominant organisms collected in many shelf and slope benthic samples. The Chirostylidae are also diverse and comprises seven genera and 192 species. Uroptychus (124 species) is the most speciose genus of this family. Hapaloptyx, a monospecific genus from off South Africa, is poorly defined taxonomically and needs further research. Representatives of most chirostylid genera are found in all oceans, with the exception of Pseudomunida and Uroptychodes, found exclusively in the Pacific Ocean, and Hapaloptyx restricted to the Indian Ocean. Chirostylids are typically deep-water animals from the continental slope or abyssal depths and often are associated with corals such as antipatharians, alcyonaceans and gorgo- naceans. The Kiwaidae are known only from one species Kiwa hirsuta (the ‘yeti lobster’), but a second unde- scribed species is known. Kiwa hirsuta was collected at hydrothermal vent sites in the southeastern Pacific and to date kiwaids are only known from this habitat (Macpherson et al., 2005). The systematic placement of squat lobster taxa continues to be debated as families, genera and species become better defined. Previously,
