Alpheus abumusa Dehghani, Sari & Naderloo, 2018

( Fig. 1A )

Material examined. PG: Holotype: adult male, CL 8.9 mm ( ZUTC 6662 ), Qadir Park, Abu-Musa I., 25°53′45′′N 55°02′23′′E, in passageway in massive dead coral, Coll. A. Dehghani, A. Sari, R. Naderloo and H. Ashrafi, 10 May 2016 . Allotypes: adult female CL 8.8 mm ( ZUTC 6663 ), same data as holotype ; Paratypes (CL range 8–9 mm): 5 males, 7 females ( ZUTC 6667 ), same data as holotype ; 1 male, 1 female ( SMF 51375), same data as holotype .

Distribution. Only known from the Abu-Musa Island, PG, Iran.

Habitat. This species is typically found in holes or passageways of massive dead coral.

Remarks. This species is closely similar to A. parvirostris Dana, 1852 ( Fig. 6D ), A. bannerorum Bruce, 1987 , and A. maindroni Coutière, 1898 , based on the shape of the major chela palm. It is discriminated from these species by the lack of spine on the merus of the third pereiopod. Alpheus bannerorum always shows obvious eye-like spots (see Bruce, 1987: pl.1A & C) on the second and third somites of the abdomen while such spots are lacking in A. abumusa .
