Abstract
A new species of lizardfish,
Synodus nigrotaeniatus, n. sp., is described from
Lembeh Strait, North Sulawesi Province, Indonesia
on the basis of six specimens, 129.7–233.5 mm SL.
Diagnostic features include 11–12 (usually 12) dorsal-fin
rays, 12–14 anal-fin rays, 13 pectoral-fin rays, 47–49
lateral-line scales, 48–49 total vertebrae, a deep
suborbital pore with prominent surrounding fimbriae,
and a rudimentary adipose fin that is scarcely visible
without magnification. The new species is an apparent
close relative of S. sageneus (mainly Australian
distribution, but records from Sri Lanka, Bali, and
West Papua), sharing most morphological and meristic
features. Nevertheless, the two species differ in
markings, with S. sageneus lacking the black
midlateral stripe that is a key feature of S. nigrotaeniatus.
The new species has a slightly wider interobital space
than S. sageneus (mean 4.4% vs. 3.5% SL) and
slightly lower vertebral and lateral-line scale counts
(48–49 and 47–49 respectively, vs. usually 51–54 and
51–55). Both species possess a well-developed suborbital
pore, but the surrounding fimbriae of S. nigrotaeniatus
are more numerous, sometimes branched, and extend
upwards along the rear margin of the eye, compared
to those of S. sageneus, which are generally
fewer, thicker, and shorter, and do not extend along
the posterior edge of the eye.
