( Fig. 2 A–B)

Alpheus deuteropus Hilgendorf, 1879: 834 : 8–10; Coutière, 1899: 81: 255; Banner & Banner, 1966b: 80: 26; Banner & Banner, 1982: 43; Chace, 1988: 22. Crangon deuteropus Banner, 1953: 70 .

Material examined. PG: 3 males, 2 ovig. females ( ZUTC 6650 ), Abu-Musa I., in crevices of dead coral heads, Coll. R. Naderloo and A. Dehghani, 10 May 2016 ; GO: 1 male, 1 ovig. female ( ZUTC 6651 ), Chabahar Bay , Tis, in crevices of dead coral heads, Coll. A. Dehghani, 2 Oct. 2016 ,

Regional records. PG and GO: Iran (present study).

General distribution. Indo-West Pacific: South and East Africa to Philippines, Pacific to Hawaii.

Habitat. All specimens were collected from crevices of dead coral heads, Acropora sp., mostly from 2–4 m deep.

Remarks. This is the only species of the A. macrocheles ( Hailstone, 1835) species complex represented in our collections. It is easily recognized by the shape of its major chela. Banner & Banner (1983) provided a detailed description and figures of the specimens collected in Australia. The present specimens agree well, in most characters, with the Australian material examined by Banner & Banner (1982:44). This species is syntopic with A. parvirostris in the Iranian coast.
