From Comodoro Rivadavia / Rada Tilly (Chubut Province) to Puerto Deseado (Santa Cruz Province). Remarks. In Munnogonium diplonychia n. sp. the chaetotaxy of pereopods II–IV differs from that of pereopods V–VII, both in females and males (see Table 1). This bipartite arrangement has not been reported for any other species of the genus. Bifid claws are an easy-to-use character, although high magnification is required to observe them. Munnogonium quequensis n. sp. and M. diplonychia n. sp. are distinguished from the remaining five species of the genus by having a tuft of setae on the anterior margin of the head. These two new species mainly differ from each other by the following characters (those of M. diplonychia in parentheses): antenna flagellum of 4 articles (6 articles); pereopod I propodus with 1 robust seta (without robust seta); claws of all pereopods simple (claws of pereopods II–IV bifid); and pleotelson with a proximal neck (pleotelson without such basal constriction). So far, three species of the genus Munnogonium have been reported from the southern tip of South America, viz.: M. falklandicum (Nordenstam, 1933) described from the Malvinas Islands, M. globifrons (Menzies, 1962) described from the Magellan Strait and M. tillerae (Menzies & Barnard, 1959) described from California and reported from the Magellan Strait by Winkler (1994). According to Nordenstam (1933) Munnogonium falklandicum has elongate stiff robust setae on the carpus and propodus of the pereopods II, VI and VII (pereopods III–V are missing in the female described by Nordenstam. We can assume, however, that these pereopods are also furnished with elongate stiff robust setae). In contrast, in M. quequensis n. sp. and M. diplonychia these carpal/propodal elongate setae are present on the pereopods II–IV only. Regarding the claws, Jean Just (pers. comm.) has had the opportunity to examine the female of M. falklandicum described by Nordenstam and he confirmed to us that this specimen has simple (not bifid) claws on the pereopod II. M. globifrons was briefly described by Menzies (1962) and a redescription of this species is badly needed. Regarding, the specimens of M. tillerae from the Magellan Strait, Winkler (1994) wrote “it seems that this species [M. tillerae] occurs in the Magellan Strait” and pointed out that the setae on the propodus and carpus of the pereopods II–VI are longer than those illustrated by Bowman & Schultz (1974). These, together with the fact that the type locality of M. tillerae is southern California, hints at the possibility of a misidentification of the Magellan specimens. In the Argentine Sea, two biogeographic provinces have been recognized as the Argentine Biogeographic Province (ABP) and the Magellan Bioeographic Province (MBP) (see López Gappa et al. 2006, and references therein). Except for M. quequensis n. sp., all other species of Munnogonium have been reported from the MBP (Fig. 13). M. quequensis n. sp. is reported from only one locality of the ABP, and most specimens (80 of the 92 specimens collected) were found attached to the surface of the asteroid Astropecten brasiliensis. Associations between isopods and echinoderms have previously been mentioned by many authors (Hatch 1947; Harty 1979; Setubal Pires 1995; Doti et al. 2008, and references therein). In some asellote species, the terminal males show a pronounced sexual dimorphism. Usually such dimorphic males have some pereonites or appendages enlarged (see Just & Wilson, 2004; Cunha & Wilson, 2006; Doti & Wilson, 2010; Riehl et al. 2012). Within Paramunnidae, the most common changes in these final males are in the pereonite 1, whose lateral parts are enlarged, and in the pereopod I which become more robust (Just & Wilson, 2004). Of the two new species described herein, only M. quequensis depicted sexual dimorphism. In this species, however, the pereonite 1 and its corresponding pereopod I are not displaying any change. In contrast, the basis and ischium of the pereopods II and III are enlarged (see remarks of M. quequensis). It is noteworthy that Bowman and Schultz (1974) and Wilson (1997) reported a similar sexual dimorphism in the pereopod II of Munnogonium tillerae and M. cf. tillerae, respectively.Published as part of Doti, Brenda L. & Roccatagliata, Daniel, 2013, Two new species of the genus Munnogonium (Isopoda: Asellota: Paramunnidae) from Argentina, pp. 301-319 in Zootaxa 3717 (3) on pages 310-317, DOI: 10.11646/zootaxa.3717.3.1, http://zenodo.org/record/22239
