Etymology: Parascyllium: para (Gr.), near, i.e., presumed to be related to Scyliorhinus (now in Scyliorhinidae): skylion, Greek for dogfish or small shark (See ETYFish); sparsimaculatum: sparsus (L.), sparse or few; maculatum (L.), spotted, referring to relatively larger (and hence fewer) spots than congeners (See ETYFish).

簡短描述
檢索表 | 型態特徵 | 形態測量圖
脊椎骨: 45 - 46. Body yellowish-brown with relatively few, large, diffuse-edged, rusty-brown spots; collar-like saddle over gill region extremely faint. Head relatively large (length greater than 16% TL). Eyes large (horizontal diameter >11% HL). Pectoral fin large, anterior margin at least 10% TL. Dorsal fins relatively tall, erect with angular apices. Upper jaw with 43-49 teeth rows. Differs from P. ferrugineum and the more heavily spotted "P. multimaculatum" morph by having a larger eye (versus <11% HL); slightly more than tooth rows (versus 38-41); fewer and much paler spots on the body ; and more erect and angular dorsal fins (Ref. 41629).
身體土黃色具有相當少見的﹐大的, 擴散的-邊緣, 赭褐色斑點; 像頸圈一樣的鰓部之上非常模糊。 頭部相當大的.(長度大於 16% TL) 眼大的.(水平的直徑 >11% HL) 胸鰭大的, 前緣至少 10% TL。 背鰭相當高的, 以有角的頂點豎立。 上頜有 43-49 齒列。 藉由有一個有別於 P. ferrugineum 與更很重有斑點 " P. multimaculatum" 變種較大的眼;(對 <11% HL) 約略更超過齒列;(對 38-41) 在身體上的較少數與較灰白斑點 ; 而且比較直立三角形的背鰭.(參考文獻 41629)
