Information: |
Distinguished from all
of its congeners with the exception of D. royeroi by the
combination of the possession of elongate, symphyseal teeth on the
dentary, a reduced lateral line not extending posteriorly on the
body beyond the abdomen, an edentulous vomer, a dorsal fin with
only 4 segmented rays and without a spinous first fin ray, an obliquely-truncate
margin on the caudal fin, and the lack of horizontally-elongate,
stellate, dark chromatophores when the chromatophores are expanded.
Denticetopsis sauli is distinguished from D. royeroi
by the posterior extent of the margin of the maxilla (extending
at least one eye diameter past the posterior margin of the orbit
versus extending only slightly beyond the posterior margin of the
orbit, respectively), the body depth (17.1-19.5 of SL versus 23%
of SL, respectively), and the extent of the membranous connection
between the caudal and anal fins (membrane distinctly incised versus
without a distinct notch, respectively). |
