Diagnosis
.
Petasma: In dorsal view, the proximal region occupies 3/4 of the distolateral projection length, with
rounded posterior margin. The distal region is as long as wide and bears a convex row of teeth and the opening, which is wide and rounded. In ventral view the row of teeth of the posterior margin enters the proximal region but ends abruptly before its wider portion. In this species the carina of the ventral surface of the proximal region is absent. In dorsal view the
appendix masculina
is subcircular but less rounded than in
X. kroyeri
and its protruding tip has many spine rows. The posterior rounded projection is longer and narrower than in
X. kroyeri
. In ventral view the spines are more prominent in the margins and become smaller over the central concave surface.
Etymology
.
The specific epithet “dincao” is given in the honour of the late Dr. Fernando D′Incao, in recognition of his contribution to the Brazilian Carcinology, in particular to the study of penaeoid shrimps from the Brazilian coast. It is to be treated as a noun in apposition.
