Diagnosis.
Body robust, rostrum short, epigastric tooth and first rostral tooth separated by about same distance as that between first and second rostral tooth. Orbital, postorbital and antennal spines present, rostral plus epigastric teeth 7–10, pterygostomian and branchiostegal spines absent. Ventral antennular flagellum conspicuously depressed. Carapace with rather long densely set setae on rostrum above adrostral carina. Abdomen with sharp, high, middorsal carina from third to sixth somites. Telson with median sulcus deep anteriorly and penetrated posteriorly by longitudinal elevation merging with convex terminal portion (Modified from
Pérez Farfante 1977
).

Bathymetric distribution.
The specimens of
M. tropicalis
have been collected in Potiguar Basin between depths of
150–180 m
; their occurrence is usually between
30–915 m
(

Remarks.
The
specimens analyzed herein do not differ from the description of
Pérez Farfante
(1977)
.
The
species
M. tropicalis
was observed for the first time in
Brazilian
waters from states of
Amapá
and
Maranhão
by
Pérez Farfante
(1977)
, based on material collected by
Expedition
Oregon
, R
/
V
Prof. W.
Besnard from state of
São Paulo
, and R/V
Calypso
recorded by D'incao (1995).
Posteriorly
, specimens collected by
Ramos-Portoet al
. (2000)
under the framework
Revizee
/
Norte
expanded the geographic distribution of this species from
Northern region
of
Brazil
, in isobaths of
100 m
.
The
M. tropicalis
have a restrict distribution to
western Atlantic
. Thus, this paper fills gaps of distribution especially along the Brazilian coast, with the occurrence of
M. tropicalis
in Potiguar Basin
, northeastern Brazil.
