Alpheus pontederiae resembles A. heterochaelis in the presence of balaeniceps setae on the fingers of the minor chela and by the rounded ventral margin of pollex of larger chela, among other characters ( Christoffersen 1984), but differs from the latter species by two characters mentioned in the section on A. heterochaelis (see above).
