Distribution. Indo-West Pacific: from South Africa to PG, and GO to Japan, Australia and Hawaii.

Regional records. PG: Iran ( Banner & Banner 1981; Naderloo & Türkay 2012); GO: Iran ( Naderloo et al. 2015).

Habitat. Rocky/cobble intertidal, usually under rocks and large pieces of coral rubble, muddy intertidal, estuaries, mangroves. This species is typically found in the intertidal and shallow subtidal 0–3 m deep.

Remark. This species complex is common in PG and GO, especially under rocks and boulders in intertidal habitats. Alpheus lobidens shows several different color patterns and currently is a puzzling group. This species needs a thorough comparison of morphology and observed color pattern variations among individuals, which the authors have started. At least two species are currently distinguishable by the presence or absence of spine on merus of large chela and conspicuous black spots on the abdomen (see Anker & De Grave, 2016).
