robustus is often confused for A. vernalis. Three
main distinctions are in the genital segement, endopite

genital segement of A.
robusutus is rounded. On A.

of the endopod of the fourth leg is longer than it is wide
with
a convoluted inner edge. Finally, at the base
of caudal rami, A.
robustus has an extra growth.
