Discussion.
The unique
holotype
of
S. dictyogadus
(MNHN 2009-1455) was visually inspected, but no otolith was extracted and no additional observations were made to the description of
Iwamoto
et al.
(2011)
, and the figure included is based on their detailed photographs. The species is remarkable for its blunter head profile with barely protruding, short and not spatulate nasal bones, characters which are considered plesiomorphic in respect to the other members of the genus.
