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

Habitat. All specimens was collected from exposed rocky shores near to high intertidal in deep crevices of bedrock filled with coarse sand.

Remarks. A. ankeri belongs to the so-called L clade of Alpheus (senso Williams et al, 2001) and within this clade to Alpheus leviusculus complex. This is either the morphologically similar or very closely related species to A. bastardi Coutière, 1898 . In A. bastardi both sexes bear a well-developed balaeniceps, as described by Coutière (1898). While in A. ankeri no balaeniceps were observed in minor chela of both sexes.
