Portunus pelagicus (Linnaeus, 1758)

Fig. 63

Material examined

ERITREA − Mitsiwa • 1 ♀ (120 ×57.7); Raffray? Deyrolle leg.; MNCN20.04/03208 .

Remarks

First record for Eritrean waters, although there is a record very close in the northern waters of Djibouti (DecaNet 2025). The rostral area and shape of the ventral lobe of the propodus of P5 may differentiate this species from P. segnis (Forskål, 1775) (see Lai et al. 2010).

For identification, see also Lai et al. (2010) and Naderloo (2017).
