Etymology: Scorpaenodes: Latin, scorpaena = a kind of fish, 1706 + Greek oides = similar to (Ref. 45335); quadrispinosus: From the Latin quattor meaning four and spina meaning spine, in reference to its diagnostic four suborbital spines (Ref. 46823) More on authors: Greenfield & Matsuura.

Max length : 10.0 cm SL male/unsexed; (Ref. 76833)
soft rays: 5 - 6. Distinguished from all other Scorpaenodes species by having the first two spines on the suborbital ridge extending dorsally above the lower orbit margin; no distinct dark spot on opercle, subopercle, or spinous dorsal fin; pectoral fin rays usually 17; vertical scale rows 39-43; head and upper body light cream overlaid by dark brown to black pigment pattern; lower half of body light cream to white, edges of scales on lower half pink (Ref. 46823); Suborbital ridge with four spinules; presence of interorbital and coronal spines, small; depth of body 2.8-3.1 in SL (Ref. 90102).
Found in coral reefs in 0-12 m (Ref 90102).
