Palaemon semmelinkii ( De Man, 1881)

( Fig. 2D, E )

Material. 17 females & 6 males ( ZUTC 6855 ), Gwater Bay , Gulf of Oman, 25°12’1”N, 61°32’34”E, mangrove creeks, 26.04.2019, coll. H. Ashrafi and M. Shojaei ; 1 female & 1 male ( ZUTC 6856 ), Bandar Khamir , Persian Gulf, 26°58’45.37”N, 55°39’14.36”E, mangroves, 25.05.2019, coll. H. Ashrafi.

Habitat and habit. This species was found under debris in mangrove creaks with high density of pneumatophores.

General distribution. Indo-West Pacific.

Remarks. These specimens are completely consistent with the description of De Man (1881), and description and drawings provided by Holthuis (1950). However, this species was recorded from Singapore by Anker & De Grave (2016) with different color pattern. As their specimen seems to bear a sub-distal tooth on the rostrum and considering descriptions and drawings provided by De Man (1881), Holthuis (1950) and Chace & Bruce (1993), it is likely the Singaporean specimens belong to a different species.
