AE013E7BFE12FFF9FF06F9D5FB78FE99.taxon	discussion	Remarks. Goreopagurus poorei had not been reported since its original description by Lemaitre & McLaughlin (2003), which was based exclusively on specimens collected off the Freycinet Peninsula and seamounts of the Southeast Cape, eastern Tasmania. Thus, the presence of this species in South African waters represents a huge range extension to the west and across the Indian Ocean, of approximately 10,100 km (5,400 nautical miles). The specimens in the original description were collected at a depth range of 500 – 1,300 m, whereas the new specimens herein reported from South Africa were collected at a shallower depth range of 334 – 622 m. The broad distribution of this species across such an immense expanse of oceans, covering from the western Indian Ocean to the Tasman Sea in the western Pacific, might appear to be unusual. However, a good number of deepwater paguroids, such as various species in genera of the families Paguridae and Parapaguridae that live at similar depth ranges along the continental slopes, are known to also have the same or even wider distributions in the Indo- West Pacific region (e. g., McLaughlin 1997, 2002, 2004; Lemaitre 1999, 2004 a, 2004 b, 2013, 2014). Moreover, parallel distribution patterns from southern Australia to southeastern Africa were recently recorded for the caridean shrimp Leontocaris bulga Taylor & Poore, 1998, and the squat lobster Munidopsis pyrochela Ahyong, 2013. Whether or not G. poorei will be found between Tasmania and South Africa, across the vast Indian Ocean, can only be determined by more sampling of the varied deep-water habitats that exist in this oceanic region. Morphological variations of species of Goreopagurus have been sufficiently documented in each of the original descriptions of the four species currently known of this genus (McLaughlin 1988; McLaughlin & Haig 1995; Lemaitre & McLaughlin 2003; Nucci & Melo 2007). Variations are particularly visible on the expansion of the carpus and length of the chela of right cheliped, which in some species can be attributable to sexual dimorphism (G. piercei, G. garthi) or allometric growth (G. poorei). In the specimens herein reported from South Africa of G. poorei, we have noticed variations in the ambulatory legs (pereopods 2 and 3) related to sex that do not occur in other congeners or at least have not been discussed in the descriptions of species of Goreopagurus. In G. poorei, males tend to develop distinctly more slender ambulatory legs and longer dactyls than females (Figs 1, 2), and some females can have distinctly stout segments on the ambulatory legs (Fig. 2). The dactyls in males can be up to nine times as long as wide, whereas in females the dactyls can be short and wide, only about six times as long as wide. The only appreciable morphological difference between the South African specimens of G. poorei and those from Tasmania used in the original description by Lemaitre & McLaughlin (2003), is in the armature of the dactyls of the ambulatory legs. The dactyls were described by Lemaitre & McLaughlin (2003) as having ventral margins armed with a range of 10 – 13 corneous spines, whereas the South African specimens reported herein have a range of 12 – 23 corneous spines. In addition, the preungual process on the dactyl of pereopod 4 is in some specimens obsolete. The finding in South African waters of numerous specimens of Goreopagurus poorei during South African research surveys, suggests that this species is not rare. Individuals can grow to a relatively large size, and it is probably quite abundant. Thus, it seems this species has simply remained overlooked despite the various taxonomic studies and voluminous reports and catalogs on South African decapods spanning 100 years (Stebbing 1910; Barnard 1950; Kensley 1969; Emmerson 2016 a-c). This discovery also clearly suggests that, like other invertebrates, the paguroid fauna from South Africa is understudied and requires attention.	en	Landschoff, Jannes, Lemaitre, Rafael (2017): Crossing the Indian Ocean: a range extension for Goreopagurus poorei Lemaitre & McLaughlin, 2003 (Crustacea: Decapoda: Paguridae).
