20528B6EFFD6FFA5D8E5FA0BFBA4F99E.taxon	discussion	Remarks. McLay’s (1999) diagnosis of the family is accurate in most points. However, some aspects need modification or elaboration, and new characters described in this study should be added. For instance, the abdomen, instead of being “ folded loosely under the thorax ” (McLay 1999: 468), is actually firmly held in Acanthodromia by coxal structures on mxp 3 and P 1 – P 3. In Acanthodromia, the abdominal somites are not “ freely movable ” (McLay 1999: 536), but there is fusion of somites 3 – 6. Admittedly, it is difficult to determine the degree of abdominal fusion. Although traces of sutures are still visible in places, they are concealed by numerous spines. In any case, somites are functionally ankylosed in the specimens examined so far. To this effect, I follow Ng et al. (2008: 14) in that “ we here regard fusion as segments which are immobile and cannot articulate with each other, regardless of whether the sutures are visible ” at varying degrees. Some characters are redefined and added. Orbits either elongate, deep, obliquely arranged or shorter, shallower, more transversal. Frontal margin variously projecting. Posterior margin of carapace rather concave. Mxp 3 more or less opercular; basis and ischium of endopod fused but suture distinct, either complete or not. Narrow shield formed by sternites 1 and 2 or 1 – 3; following thoracic sternites either completely included between coxae of pereopods or with narrow lateral portion intercalated between abdomen and pereopods; sternum forms a plate that regularly declines posteriorly; sternite 8 tilted, located in another plane than preceding ones. Anterior sternites 1, 2 small, fused into a narrow shield, either pentagonal, onion-shaped or, more rarely, triangular; stacking up of anterior sternites may be recognised by location of gynglymes for articulation of mxp 1 – mxp 3 along thick margin of shield (Figure 4 A). Sternite 3 either clearly distinct, visible (plesiomorphy), or represented at base of shield by short band, of about same width as sternite 4 in its anterior part (apomorphy); suture 3 / 4 indicated by change of level, straight or convex, or marked by denticulate crest. Sternites 4 – 7 (except episternites) fused into undivided plate, with parallel margins, medially forming flat area, varying from moderately wide to wide. Sternal sutures 4 / 5 – 6 / 7 hardly visible, hidden by borders of sterno-coxal depressions; suture 4 / 5 may be medially replaced by convex line; suture 7 / 8 present, even in males, relatively short in both sexes. Sterno-abdominal depression deep, completely covered by male abdomen over entire length and width, or shallow, not well defined, always with medial flat floor. Deep sterno-coxal depressions present at level of P 2 – P 4 (Figures 2 A, B, 4 A). Male abdomen either long, narrow, completely accommodated in sterno-abdominal depression, or shorter, relatively broad even in males, flexible; telson reaching base of mxp 3 or level of mid-sternite 4; lateral margins of abdomen (uropod margin included) may be slightly modified (Acanthodromiinae n. subfam., Paradynomeninae n. subfam.), and not modified in the two other subfamilies. Abdomen with somites 1 – 6 free or with somites 3 – 6 fused in both sexes (at least in Acanthodromia margarita), sutures still partially visible. Abdominal holding either firm in both sexes and involving coxae of mxp 3 and P 1 – P 3 (Acanthodromiinae n. subfam.), or less so but still fairly tight (Paradynomeninae n. subfam.), or loose and performed by a structure which is either coxal (Metaynomeninae n. subfam.) or sternal (Dynomeninae). Sexual dimorphism of abdominal somite 6 correlated with sexual dimorphism of uropod. Vestigial pleopods present on male somites 3 – 5, biramous (two rami either equal or, more often, unequal, exopodite being longer than endopodite); exceptionally (Dynomene praedator A. Milne-Edwards, 1879), pleopods 3 – 5 uniramous; thus pleopodal formula complete (Figure 3 B). Uropods as dorsal plates (Figure 5), varying from small, slightly mobile to well developed, immobile (even at so great extent that penultimate abdominal somite excluded from reaching abdominal lateral margin), usually not prominent in males (slightly prominent in Paradynomeninae n. subfam.), may be sexually dimorphic (larger in females). Apertures of spermathecae ending well apart from each other, slightly behind female gonopore on P 3 coxa. Chelipeds usually equal, may be unequal at least in males, and homomorphic, slightly dimorphic sexually (however with marked growth and modifications in large males of Dynomene praedator). P 5 strongly reduced, not movable, directed obliquely between posterolateral margin of carapace and P 4; basis-ischium free or fused to merus; subchelate mechanism involving dactylus opposed to distal extension of propodus, sexually dimorphic, more developed, more spinous in females. P 5 coxa modified in males, extended in long projection enclosing most of penis (Figure 4 C – F). Endophragmal skeleton with junction between phragmae formed by fusion; skeletal parts variously layered (cf. Secretan 2002). Gills (cf. McLay 1999) usually 19 (including 6 podobranchs) + 7 epipods, with basically phyllobranchiate structure, but plates very variable in shape and number of epibranchial lobes.	en	Guinot, Danièle (2008): A re-evaluation of the Dynomenidae Ortmann, 1892 (Crustacea, Decapoda, Brachyura, Podotremata), with the recognition of four subfamilies.

20528B6EFFD0FFA7D8E5F93EFE6DF9B6.taxon	discussion	Remarks. The subfamily is monotypic, and Acanthodromia comprises only two species (Table 1). The morphology is masked by the spines which cover the whole body, so the precise outline and the grooves on the dorsal surface of carapace are not evident, which implies that potentially related fossil taxa are not easily assigned to this subfamily. The initial assignment of Acanthodromia to the Dromiidae (A. Milne-Edwards 1880; Alcock 1899) and subsequent transfer to the Prosopidae, subfamily Pithonotinae Glaessner, 1933 (Wright & Collins 1972), illustrates well the “ curious mixture ” (McLay 1999: 534) of characters, already pointed out by A. Milne-Edwards & Bouvier (1902). The present study has shown that there is strong support for the interpretation that the Recent Acanthodromia retains ancestral characters and is the most primitive of all extant dynomenids.	en	Guinot, Danièle (2008): A re-evaluation of the Dynomenidae Ortmann, 1892 (Crustacea, Decapoda, Brachyura, Podotremata), with the recognition of four subfamilies.

That the Metadynomeninae n. subfam. and the Sphaerodromiinae (see McLay & Crosnier 1991) appear related is due to a number of comparable plesiomorphic features, as has already been noted by McLay (1991: 465, table 1), who illustrated the similarities between M. devaneyi and the species of Sphaerodromia (see also discussion and key in Guinot & Tavares 2003).	en	Guinot, Danièle (2008): A re-evaluation of the Dynomenidae Ortmann, 1892 (Crustacea, Decapoda, Brachyura, Podotremata), with the recognition of four subfamilies.

20528B6EFFC6FFB5D8E5FA86FAB6FCEE.taxon	description	The Paleocene Dromilites americana Rathbun not only “ differs significantly from the type of the genus ” Dromilites H. Milne Edwards, 1837, D. bucklandii (H. Milne Edwards, 1837) (see Schweitzer et al. 2003: 21) but, moreover, the thoracic sternum figured by Rathbun (1935: pl. 17, fig. 2) does not correspond to that of a dromiacean crab and probably does not represent a podotreme condition. Consequently, the assignment of Dromilites americana to Dromilites and its attribution to the Dynomenidae, with a possible link to Kierionopsis, are not recognised here. Dromilites should be assigned to the Dromiinae (Dromiidae). Similar to Kierionopsis, Kromtitis Müller, 1984 (type species: Dromilites koberi Bachmayer & Tollmann, 1953), assigned to the Dromiidae (Müller 1984: 64, pl. 31, figs. 1 – 4; Müller & Collins 1991: 63, fig. 3 e, pl. 3, figs. 4, 5, 8; Portell & Collins 2004: 111; Beschin et al. 2002: 12; Donovan et al. 2003: 106) or to the Dynomenidae in close proximity of Paradynomene (Beschin et al. 2007: 26, 27; see also Beschin et al. 2004), can be confidently included in the Paradynomeninae n. subfam. In Kromtitis, as in Kierionopsis, the subrectangular carapace, the pronounced subdistal posterolateral teeth, the lobate and ornamented dorsal surface closely matches those of species of Paradynomene species recently described by McLay & Ng (2004). At least, in dorsal carapace features, there has scarcely been any divergence between these fossil genera and extant Paradynomeninae n. subfam. All species of Kromtitis, from the Eocene to the Miocene, are coral associates (Beschin et al. 2007: 27), as are extant species of Paradynomene. Modern Paradynomeninae n. subfam. clearly are barely modified relicts. A number of fossils, known solely from their dorsal carapaces and which conform to the general pattern of the Dynomenidae, appear as possible metadynomenines. Such is the case, for instance, of species of Dromiopsis Reuss, 1859 (type species: Brachyurites rugosus von Schlotheim, 1820) as D. elegans Reuss, 1859, with a rounded carapace, complete and deep cervical groove and lateral branchial groove, both grooves reaching and forming notches with the lateral border of the carapace. However, the genus Dromiopsis, supposed to be a dynomenid genus, is probably not monophyletic. It is premature and beyond the scope of the present paper to assign podotreme fossils to a dynomenid subfamily, the preliminary task being to attempt to include extinct genera in their appropriate family, i. e., either in the Dromiidae (and possibly in its constituent subfamilies) or Homolodromiidae or Dynomenidae, without excluding extinct families such as the Diaulacidae and also the Prosopidae which are the ancestors of the Homolodromioidea. Any affiliation based on the carapace shows only similarities and thus remains speculative at best. The nature of fossil dromiacean genera, even those that are known from a number of characters, remains questionable. For example the familial status of Basinotopus M’Coy, 1849 (type species: Inachus lamarckii Desmarest, 1822), traditionally assigned to the Dromiidae (P 4 and P 5 reduced and dorsal), is puzzling, despite the availability of both male and female abdomens with their uropods (M’Coy 1849; Bell 1858; see Guinot & Tavares 2001). Recent discoveries of more complete specimens of the Eocene Basinotopus tricornis Collins & Jakobsen, 2004, which in particular reveal sternal characters (Collins & Jakobsen 2004: 69, fig. 3, pl. 2, figs. 1 – 7), require a new interpretation based on all known data in accordance with phylogeny.	en	Guinot, Danièle (2008): A re-evaluation of the Dynomenidae Ortmann, 1892 (Crustacea, Decapoda, Brachyura, Podotremata), with the recognition of four subfamilies.
