B5CC7E23F6CD5973FAA00F04316C47DA.taxon	diagnosis	Diagnosis. Eubranchiate sphaeromatid with body approximately elliptical. Anteriorly, cephalosome separating the bases of the antennules. Eyes set slightly into pereonal tergite 1. Coxal plates of pereonites 1 - 7 separated from tergites by sutures. The seventh somite is overlapped by the sixth in adult males (stage 8), with the pleura extended postero-laterally into two small processes, which vary in shape according to species. Pleotelson domed or keeled, and terminating in an obvious terminal foramen, which may be enclosed forming a tube. Antennular peduncle articles 1 and 2 dilated and juxtaposed to ventral margins of cephalosome. All pereopods ambulatory. Both rami of pleopods 1 - 3 bearing margin of plumose setae. Endopods of uropod fused with protopods and juxtaposed to pleotelsonic margin; exopods posteriorly directed. Sexual dimorphism pronounced. Adult male with pereonal tergite 6 longer than those preceding, posterior margin with an elongate, posteriorly directed process either side of the mid-line (the bidentate process). Posterior part of pleotelson with central boss. Penes small, separate. Endopod of pleopod 2 lacking appendix masculina. Female with pereonal tergite 7 similar to those preceding and lacking bidentate process; pleotelson smooth. Ovigerous female with ventral marsupium, formed from four pairs of lamellae, which arise from pereonites 1 - 4. Mouthparts strongly metamorphosed.	en	Vieira, Pedro E., Queiroga, Henrique, Costa, Filipe O., Holdich, David M.

0D0C27A4CE19D74467984A7ABC54F433.taxon	distribution	Geographical distribution. The distribution of this species shown in Holdich (1970, 1974) has been extended by the present study. It occurs from the Shetland Islands to Tarfaya in western Morocco and Tenerife and Gran Canaria in the Canary Islands, which are the only two records of the species in Macaronesia (Fig. 5 A). Within this range Dynamene bidentata occurs in the north, northwest (including the outer islands), west and south coasts (as far as the Isle of Wight) of Great Britain, around Northern and Southern Ireland, the Channel Islands, northwest France, Atlantic Iberian Peninsula and in northwest Africa. Arrontes (1991) cites Dynamene bidentata as being the most abundant isopod species on shores in northern Spain. It is the only species present in the British Isles (with the exception of a single record of Dynamene magnitorata in southern England). It is particularly common in SW England and SW Wales, especially where the large barnacle, Balanus perforatus is present. There is one recent record for north-eastern England, which may be the result of a stranding, as are records for The Neth erlands, where it is not considered indigenous (Holthuis 1956). The closest record to the Mediterranean of Dynamene bidentata is Tarifa, in southern Spain (Guerra-Garcia et al. 2011, Izquierdo and Guerra-Garcia 2011, Guerra-Garcia et al. 2012, Torrecilla-Roca and Guerra-Garcia 2012).	en	Vieira, Pedro E., Queiroga, Henrique, Costa, Filipe O., Holdich, David M.

E48D6CD00BF54CAE35DF16579833EBF5.taxon	distribution	Geographical distribution. The distribution of this species shown in Holdich (1970) has been extended by the present study. It is the most commonly recorded Dynamene species in the Mediterranean, occurring from the Balearic Islands in the west to the coast of Israel in the east, although there are only a few records for the North African coast (Fig. 5 B). It has been frequently recorded around the Greek islands and mainland coast of both Greece and Turkey. The most northerly record is for Croatia in the Aegean Sea. It has also been recorded for a number of countries around the Black Sea (Bulgaria, Romania, Turkey and Georgia) (Fig. 5 B). Most records in the literature refer to Dynamene torelliae, which is now considered synonymous with Dynamene bicolor.	en	Vieira, Pedro E., Queiroga, Henrique, Costa, Filipe O., Holdich, David M.

691D7BF17F43230B5F39E3B13CCB6568.taxon	distribution	Geographical distribution. The distribution of this species shown in Holdich (1970) has been extended by the present study. It is the most meridional of the Atlantic species, occurring from Galicia in north-western Spain to Nouadhibou in Mauritania (Fig. 5 D). This is the currently known southern limit of Dynamene species of the NE Atlantic-Black Sea axis. It is widespread in the Macaronesian islands and in the eastern and western Mediterranean (Fig. 5 D). The most northerly record comes from the Venice Lagoon in the Adriatic Sea. It is also the only Dynamene species recorded from the Red Sea, in the Gulf of Aqaba (Fig. 5 D). Glynn (1972) recorded a species that is clearly Dynamene edwardsi from the Suez Canal. Picker and Griffiths (2011) have recorded this species (as Dynamene bidentata) from South Africa.	en	Vieira, Pedro E., Queiroga, Henrique, Costa, Filipe O., Holdich, David M.
