These characters clearly differentiate this species from the three other sympatric Squalus species. Squalus formosus is morphologically closest to S. albifrons from eastern Australia but differs in the following characters: first dorsal fin with a distinct, broad white anterior margin (v. no distinct white marking); second dorsal fin height 5.7–6.4 v. 4.3–5.1% LT; first dorsal fin height 9.0–10.5 v. 7.7–8.9% LT, anterior margin 12.4–14.6 v. 10.9–12.7% LT; eye slightly larger 4.8–5.3 v. 4.4–4.8% LT. Squalus formosus can be further distinguished from other Squalus species in the following combination of characters: pre-second dorsal length 3.7–4.4 times pectoral-fin anterior margin; preoral length 2.2–2.3 times horizontal prenarial length; head length 4.0–4.7 times eye length; interorbital width 1.4–1.6 times horizontal preorbital length; posterior margin of second dorsal fin deeply concave; second dorsal-fin spine with a broad base; dorsal surface of head dark, sharply demarcated from paler ventral surface; 45–46 monospondylous centra, 94–95 precaudal centra, 123–124 total centra; adult maximum size at least 73 cm LT (Ref. 87791).
