During an actuopalaeontological study numerous resin casts were made in the Bay of Safaga (Red Sea, Egypt). This yielded, among others, several burrow replicas of Alpheus migrans Lewinsohn & Holthuis, 1978 (Decapoda, Alpheidae), a suspected Lessepsian migrant first described from the eastern Mediterranean. In addition, one specimen was captured while casting, a second was entombed in one of the resin casts. The burrows have the general shape of a three-dimensional, dichotomous system modified by a reticulate pattern. They consist of shallower primary U's connected by deeper secondary U's, have up to 6 openings at the surface and reach down to a maximum depth of 70 mm. This is the first record of this species from the Red Sea, where it occurs abundantly in muddy sediments between 34 and 36 m water depth.
