Description: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). Etymology:
The specific name sauli: In honour of William
G. Saul (b. 1944), collection manager of the Ichthyology
Department of the Academy of Natural Sciences of Philadelphia,
who participated in the collection of the type series
and brought this species to the author’s attention.
