Remarks

Among the 52 specimens of A. laevidorsalis with MNCN20.04/10271 code, there were two other species of leucosids. The specimens MNCN20.04/41938 were mixed with other two species under the Polybiidae family and the three specimens of MNCN20.04/41936 were also mixed but without assigned family within the Decapoda . The 13 specimens of A. laevidorsalis MNCN 20.04/11657c were mixed with bivalves, polychaetes, and other decapods, simply identified as “ Decapoda ”. The four males of MNCN20.04/41924 were mixed with other decapods without determination. The specimen MNCN20.04/20979 was covered with organic remains, possibly some type of microalgae, which made it look like another species with a rough carapace.

For identification see also Galil (2009).
