Body moderately elongate, compressed, covered with rather large, deciduous cycloid scales. Head moderately large; interorbital space convex; cheeks and opercular bones scaly. Mouth large, oblique; lower jaw slightly projecting. Maxillary reaching below mid-orbit to slightly behind of it. A single long and thin supramaxillary. Posterior edge of maxillary deeply concave with posterodorsal and posteroventral angles sharp and posteroventral angle extended backward and downward resulting in an obliquely truncated posterior rim of the maxillary. Premaxillary with a pair of canines near symphysis and an additional much smaller canine-like tooth inward from the main canine tooth on each side (rarely absent), followed posteriorly by a wide band of minute chagrin-like teeth. Dentary with a pair of canines and a band of minute conical teeth near symphysis, followed posteriorly by a row of several small conical teeth and two to four enlarged canine-like teeth on each side. Vomer with a V-shaped patch of granular teeth, followed posteriorly by 1-4 (usually 2 or 3) enlarged conical teeth on each side. Palatines with 1-3 rows of granular teeth, teeth of the innermost row sometimes somewhat enlarged. Preopercle with outer edges of ventral branch and preopercular lobe finely serrated; preopercular lobe with 2-3 weak longitudinal crests; inner edge of preopercle with 2-6 denticles (their counts are usually different on the right and left sides in one fish). Sub- and interopercle with smooth outer edge. Opercle with 2 weak and short, flat spines. Pseudobranch very large and wide with 28 to 38 elements.</p> S. philippinensisBMNH 1879.5. 14.167 (syntypes, n = 4)Philippines: Sulu SeaI +14 - 15 I + 5 2 - 3 + 13 - 15 = 15 -17 18 - 232 - 4 about 22 S. pellucidusBMNH ZMH 8717 1890.7.31.13 - 15 (n = 1) (n = 3)Laccadive Bay of Bengal SeaI + 14 - 16 I + 16 I + 5 I + 5 3 - 4 + 4 + 16 = 20 15 -17 = 18 -21 18 - 23 223 - 4 4 24? - 27 – S. adeniBMNH 1939.5.24.880 - 891 (n = 5)Gulf of AdenI + 14 - 16 I + 5 3 - 4 + 20 -21 = 23- 24 16 - 182 -4 –5057 (paratypes, n = 4) Gulf of Aden and off southern Somalia I + 14 - 16 I + 5 4 -5 + 17 - 18 = 22 - 24 15- 203 - 6 –ZMH 5055 (holotype)Gulf of AdenI+ 14 I + 5 5 + 18 = 23 163 / 4 27 / 29 S. argyreusZMUC P 44272 (n = 1)Madagascar ChanelI + 13 - 14 I + 5 2 + 12 = 14 30- 325 / 6 –ZMMGU 13269 &amp; 15338 (n = 5)S.

Three predorsals, predorsal formula /0+0/0+2/. Anal fin originates behind the level of the second dorsal-fin origin. Proximal-middle radial of first anal-fin pterygiophore is narrow and almost straight, wedge-shaped, lacking a groove at anterior edge. Pectoral fin reaching far before a level of the second dorsal-fin origin. Pelvic fins inserted below the level of the pectoral-fin base or just anterior to it. Pelvic-fin spine serrated along its outer edge; all other fin spines smooth. Caudal fin forked. Anus situated near origin of anal fin. Vertebrae 10 + 25.&amp; 5056 ZMH <p>Otoliths (Fig. 5 D-F) slender, elongate, thin, up to about 10 mm length. Otolith length to otolith height = 1.85-2.0; otolith height to otolith thickness about 4.5. Outline with well-developed rostrum and symmetrical angular posterior tip. Dorsal rim with broad, obtuse mediodorsal angle and distinct postdorsal angle close to posterior rim; no or only weak excisura and antirostrum. Ventral rim deepest slightly in front of its middle, below collum of sulcus. Dorsal and posterior rims crenulated to various degrees; ventral rim mostly smooth. Inner face slightly convex with slightly supramedian positioned sulcus. Sulcus rather shallow, with narrow, long cauda and wide, shallow ostium. Cauda length to ostium length = 1.05-1.15; ostium width to cauda width = 2.1-2.4. Ostium opening anterior-dorsally along otolith rim between rostrum and antirostrum, filled with well-defined colliculum. Cauda tapering, slightly bent at its tip, terminating close to posterior tip of otolith, with poorly defined colliculum. Dorsal depression wide; ventral furrow distinct, close to ventral rim of otolith anteriorly and bending away from it backwards towards tip of cauda. Outer face slightly concave, with fine radial furrows.</p></div> 	https://treatment.plazi.org/id/A574F8317B6CFFC1FF6DFD54FB3E75FA	Public Domain	No known copyright restrictions apply.
