Dardanus arrosor (Herbst, 1796)

Fig. 1B

Material and measurements: 2 right propodi (MSNM i27885 – hpa: 11 mm; li: 4 mm; lpa: 16 mm; MSNM i27887 – hpa: 9 mm; li: 3 mm; lpa: 14 mm).

Description: Palm longer than high, with upper and lower margin almost parallel; palm covered with sinuous transverse crests, dentate anteriorly; triangular index, relatively long, with dentate transverse crests; occlusal margin with some weak teeth.

Discussion. The studied propodi show the typical morphological characters of the extant Dardanus arrosor (Herbst, 1796) , widespread along the Atlantic coastlines ( Portugal and Africa) and in the Mediterranean area where this species lives at a depth of 20- 50 m. Ristori (1891b) reported some incomplete dactyli from the Pliocene sands of Monte Mario (Rome) (now assigned to the Early Pleistocene by Cosentino et al., 2009) ascribed to Pagurus striatus (Latreille, 1803) , juvenile synonym of Dardanus arrosor (Herbst, 1796) .
