03E5D221E410FFC1FF4BF8D2FC13FADF.taxon	discussion	Remarks. Talitrus is the only member of the Talitridae with the combination of no sexual dimorphism in gnathopod 2 coupled with an incrassate antenna 2. It is also the only talitrid with the combination of an incrassate second antenna combined with no palmate lobes on gnathopod 1. Talitrus is the only European / Mediterranean talitrid genus with a non-enlarged male gnathopod 2 (apart from the cavernicolous Palmorchestia Stock & Martin, 1988).	en	Lowry, J. K., Myers, A. A.

03E5D221E413FFC6FF4BFAE3FBC2F809.taxon	discussion	Remarks. We have searched unsuccessfully for the types of Orchestia cloquetii in the most reasonable repository, the Muséum national d’Histoire naturelle, Paris. All of Audouin’s invertebrate material from Savigny’s collections from Egypt is apparently lost (Paula Martin-Lefèvre pers. com.). Given the ambiguity in the identity of T. cloquetii as a result of the present study, we establish a neotype from Crete (NHMUK 2018.1538) for this species in order to stabilize the identity of the species. We have also examined specimens from Israel that fit Talitrus cloquetii as understood here and we regard the species as having a wide distribution in the south-eastern Mediterranean. The neotype locality is not very near to the original type locality (Egypt), but it is in the same geographic area and occurs sympatrically with Deshayesorchestia deshayesii (Audouin, 1826) described from the same original locality. Talitrus cloquetii has elongate pereopods 6 – 7 (short in T. saltator) and short uropods (long in T. platycheles). Pereopod 7 basis posterior margin is flattened (convex in both T. saltator and T. platycheles).	en	Lowry, J. K., Myers, A. A.

03E5D221E413FFC6FF4BFAE3FBC2F809.taxon	distribution	Distribution. The known distribution of T. cloquetii in the Mediterranean is incomplete (fig. 1). De Matthaeis et al. 1998 recorded a genetically distinct population of Talitrus from Kos and Tilos in the southern Aegean Sea that we interpret as almost certainly being T. cloquetii. It is known from Crete and Karpathos in the Sea of Crete. There are no reports of Talitrus along the southern Turkish coast or from the coasts of Syria or Lebanon. It is then known from Israel (this paper) and the Nile Delta, Egypt (Audouin 1829). Southern Aegean Sea (Crete, Karpathos) and Levantine Sea (Israel, Egypt).	en	Lowry, J. K., Myers, A. A.

03E5D221E417FFC9FF4BF933FF39FCA6.taxon	distribution	Distribution. The known distribution of T. platycheles in the Mediterranean is patchy (fig. 1). There are no records of Talitrus along the southern coast of Spain or the south-western Mediterranean coast of France. Talitrus platycheles is known from Venice, Adriatic Sea (this paper). Sezgin & Kataðan (2007) reported T. saltator from the Black Sea. Based on records of T. platycheles from the Aegean Sea we consider the record of Sezgin & Kataðan (2007) to most likely represent T. platycheles. Talitrus platycheles is known from the Canary Islands (Chevreux 1893) and along the coast of Morocco (Charfi & El Gitari 2008), Algeria (Chevreux 1893) and Tunisia from Tabarka in the west to the Gulf of Hammamet in the east (this paper based on samples from Dr El Gtari and Dr Faouzia Charfi). There are no records from Tunisia east of the Gulf of Hammamet. Western Mediterranean (France, Sardinia, Corsica), Ligurian and Tyrrhenian Sea (Liguria, Tuscany); Adriatic sea (Venice, unconfirmed records fromMontenegro, Veneto, Emilia-Romagna, Apulia); western Peloponnese (Methoni); northern Aegean Sea (Anaifi, Astipálea, Kos, Tilos);? Black Sea; North Africa (Algeria, Tunisia); Canary Islands.	en	Lowry, J. K., Myers, A. A.

Not significantly different from male.	en	Lowry, J. K., Myers, A. A. (2019): Talitrus saltator (Montagu, 1808), a species complex (Amphipoda, Senticaudata Talitroidea, Talitridae).

03E5D221E41BFFCEFF4BFC2BFD30FD52.taxon	discussion	Remarks. Type material of T. saltato r (Montagu, 1808) cannot be traced in the collections of the British Museum and is considered lost (Lauren Hughes pers. com.). Given the historical ambiguity in the identity of T. saltator, we therefore establish a neotype for this species in order to stabilize the species. Talitrus saltator differs from both T. cloquetii and T. platycheles in its more robust build, in particular its shorter and stouter pereopods 6 – 7. It differs from T. cloquetii in the shape of the posterior margin of the basis of pereopod 7 that is evenly convex in T. saltator but flattened in T. cloquetii. It differs from T. platycheles in having a short uropod 3 with the ramus not markedly tapering and an unswollen merus on the male gnathopod 1.	en	Lowry, J. K., Myers, A. A.

03E5D221E41BFFCEFF4BFC2BFD30FD52.taxon	distribution	Distribution. This species is widely distributed along European coasts, from Norway and the Baltic Sea in the North, around British and Irish coasts, the coast of France and northern Spain and the Azores in the south. There are no records of Talitrus along the south coast of Spain.	en	Lowry, J. K., Myers, A. A.

Three males, 5 females (MNHN-IU- 2019 - 2268), traps just above high tide mark on black sand (high energy with surf zone) beach, Praia do Populo, San Miguel, the Azores, Portugal (37 ° 45 ’ 02.47 ” N 25 ° 37 ’ 23.91 ” W), Lucia Fanini, 15 – 16 August 2018; 2 unsexed, Azores, 1955, G.

03E5D221E41CFFCEFF4BFD67FD2AFA66.taxon	discussion	Discussion. Azores specimens are white with brown suffusions and jet black saddles. This colouration may confer a degree of camouflage against the black volcanic sand of the island. The material agrees well with the neotype of T. saltator from Ireland, but differs in proportions. The appendages of Azores specimens are more slender; gnathopod 1 of both sexes is more elongate and slender, the propodus almost 3 × as long as broad, whereas in the neotype, it is only a little more than 2 × as long as broad. Pereopod 7 propodus is also more long and slender than that of the neotype. Uropod 3 peduncle and ramus are a little longer and the terminal robust seta is only about three quarters the length of the ramus in Azores males, whereas ramus and setae are subequal in length in the neotype. Antenna 2 peduncular articles 4 and 5 are much longer in Azores material and the anterior margin of article 4 is naked but with several setae in the neotype. In the Azores material the anterior margins of antenna 1 peduncular articles 2 and 3 are also naked but with a medial seta in the neotype. The Azores population has been isolated from other Atlantic populations for millions of years and may represent a distinct species. However, as we have not assessed the variation amongst other Atlantic populations, we hesitate to raise the Azores population to specific rank.	en	Lowry, J. K., Myers, A. A.
