( Fig. 4F )

Alpheus lutosus Anker & De Grave, 2009 ; De Grave & Ashelby, 2011, Naderloo & Türkay, 2012: 10 .

Material examined. PG: 2 males, 3 females ( ZUTC 6706 ) Bandar-Mahshar, muddy flat, Coll. R. Naderloo and A. Dehghani, 26 Nov. 2015 ; 3 males, 2 females ( ZUTC 6707 ), Bandar-Deylam, muddy flat, Coll. R. Naderloo & A. Dehghani, 28 Nov. 2015 ; 1 male, ( SMF 51383), Bandar-Mahshar, muddy flat, Coll. R. Naderloo & A. Dehghani, 26 Nov. 2015 .

Distribution. It seems to be endemic to the Persian Gulf ( Iran and Kuwait).

Regional records. PG: Iran ( Naderloo & Türkay, 2012, present study), Kuwait (Anker & De Grave 2008); GO: No record.

Habitat. In intertidal and estuarine mudflats, in burrows made under boulders or in muddy banks.

Remarks. According to Anker and De Grave (2009), David Jones collected a series of Alpheus from the intertidal mudflats of Kuwait in 2004 and provisionally identified these as A. euphrosyne De Man, 1897 . Later, this material was examined and was designated to a new species A. lutosus Anker & De Grave (2009) . This species is easily distinguished from its PG/GO congeners by the presence of a distinct spine-like tooth on the mesial surface of the major chela palm. The species also has a distinctive blue patch on the distal region of uropods. The collected specimens agree well with the description and illustrations provided by Anker & De Grave (2009). These authors also mentioned that A. lutosus is syntopic with A. lobidens De Haan, 1849 , and A. rapax Fabricius, 1798 , in the muddy estuaries of Kuwait. In our samples, A. lutosus was only found syntopic with A. euphrosyne De Man, 1897 .
