            <p>71°01’W).</p>
            <p> Remarks. Over time,  F. fuegiensis has been allocated in three distinct genera; however, the species was not fully diagnosed, as we do here, and the appendages were lacking full illustrations and descriptions. Alonso de Pina (2003a) reported the possibility to observe certain variations among individuals of this species, mainly regarding the number of thin and stout setae on mouthparts and appendages. These variations were also found in the analyzed material, especially on the formula of facial setae present on the article 4 of antenna 2. They appear to be lower in number in smaller specimens and more numerous in larger ones, which can be related to the maturity of each individual. The material analyzed here shows 3-4-2 as the most common facial stout setal formula on the fourth article of antenna 2, while the original work by Barnard and Barnard (1980) shows 3-3-2. Additionally, Alonso de Pina (2003a) reported three different patterns in Argentina: 3-4-3 and 3-4-1 for specimens collected at Golfo Nuevo; and 3-3-3 for individuals from Golfo San José. </p>
            <p> Chiesa and A lonso (2011) proposed an identification key to world species of  Fuegiphoxus using a variable character as a diagnostic one (facial setal formula on article of antenna 2). Thus, we recommend disregarding this character in the third step of the key, and still consider the other ones, and the key will work properly for future identifications. </p>
            <p> Geographic distribution. The species is well represented in southern South America, ranging from southern Uruguay (Atlantic coast), through the Beagle Channel, to Valparaiso, Chile (Pacific coast) (Alonso, 2012). Also, there are records of  F. fuegiensis from South Shetland Islands (Antarctica), Tristan da Cunha and South Georgia Islands (Alonso de Pina et al., 2008). </p>

            <p>Diagnosis. See Andrade and Senna (2020c). Additional description. Epimeral plate 1 anterior margin rounded, with 2 setae, ventral margin with 7 plumose setae, posteroventral corner with small, rounded hump, posterior margin convex. Epimeral plate 2 anterior margin weakly concave, with 6 facial plumose setae, posteroventral corner with small subacute hump, posterior margin weakly crenulate, with 4 setae. Epimeral plate 3 anterior margin concave, anteroventral corner rounded, posteroventral corner strongly produced into large spine, posterior margin weakly crenulate, with 6 setae and 1 setule, with oblique facial row of 8 stout setae extending from posteroventral margin to middle of plate, decreasing in length. Urosomite 3 produced as large acute hook dorsally. Uropod 1 peduncle dorsomedial margin with 4 stout setae, dorsolateral margin with 9 stout setae; outer ramus slightly longer than inner, dorsal margin with 7 stout setae, bearing 2 subapical nails; inner ramus dorsal margin with 4 stout setae, bearing 1 subapical nail. Uropod 2 peduncle dorsomedial margin with 7 stout setae; outer ramus slightly longer than inner, dorsal margin with 6 stout setae, bearing 2 subapical nails; inner ramus dorsal margin with 3 stout setae, bearing 1 subapical nail. Uropod 3 peduncle dorsomedial margin with 1 stout seta distally, ventrolateral margin with 6 stout setae; outer ramus 1.2 × longer than inner, article 1 ventrolateral margin with 3 sets of stout setae: 2-2-3, article 2 elongate, with 2 setae subapically; inner ramus ventrolateral margin with 2 setae, subapically with 1 seta.</p>
            <p>Typelocality. Argentina, Buenos Aires, El Rincón</p>
            <p>(39°49’58”S 61°35’02”W).</p>
            <p>Remarks. This species was described from type material from southern Buenos Aires Province (Argentina) and was recently recorded from southeastern and southern Brazil (Andrade and Senna, 2020c).Some morphological differences are clear when comparing the drawings of the type material (Alonso de Pina, 2003b) plus the Brazilian records (Andrade and Senna, 2020c) with the ones belonging to this study. For example, while the epimeral plate 1 ventral margin presents five to six plumose setae here, and in Alonso de Pina (2003b), the plates from Andrade and Senna (2020c) show only two slender setae on the antero- and posteroventral corners. The posterior margin of epimeral plate 2 is weakly crenulate in the present material, whereas it is smooth in the other works. The facial row of setae of the epimeral plate 3 is composed of eight and nine setae in this study and in the type material respectively; however, the Brazilian material shows 10 setae.</p>
            <p>Although it is possible to observe some other subtle differences regarding number of stout setae on the uropods, the species can be easily recognized by the produced spine on third epimeral plate and urosomite 3, and distal combs on peduncle of uropods 1–2.</p>
            <p> Geographic distribution.  Argentina: El Rincón (39°49’58”S 61°35’02”W), off Buenos Aires Province (36°29’S 55°57’W; 36°23’S 53°32’W; 37°56’S 57°07’W) (Fig. 25) .  Brazil: states of Rio de Janeiro, São Paulo, and Santa Catarina . </p>

            <p>  Type locality. Argentina,  Península Valdés , Punta </p>
            <p>Pardelas (42°37’S 64°16’W).</p>
            <p> Remarks.  Metharpinia protuberantis was described with material from Chubut, Argentinean Patagonia (Alonso de Pina, 2001). The species is considered intermediate between  Metharpinia Schellenberg, 1931 and  Microphoxus Barnard, 1960 , being easily distinguished by presenting epimeral plate 3 posteroventral corner with a strong spine pointing upwards. It is relevant to highlight that a very variable character such as the facial stout setae formula (1-3- 4-3) present on the fourth article of antenna 2 is the same for both the type material and the one examined here. Besides some subtle differences, such as the setation on mouthparts and appendages, there are some distinctions when compared to the type material (characters of type material in parentheses): pereopod 7 propodus distally smooth, without processes (vs combed, with five digital processes); epimeral plate 3 posterior margin smooth (vs weakly crenulate); uropod 1 dorsodistal corner not combed (vs coarsely combed). </p>
            <p>In this study, we propose a diagnosis of the species for the first time. This new record represents the northernmost for the species (Fig. 25), previously known from the northern Magellanic region, on the Atlantic coast of Patagonia.</p>
