Abstract: | Parascyllium sparsimaculatum sp. nov. is described using external and skeletal morphologies on the basis of three female specimens collected from the
continental slope off Western Australia. This new species is clearly distinguished from four congeners by having a relatively
large head (length greater than 16% of TL); a large eye (horizontal diameter of eye greater than 11% of HL); a large pectoral
fin (anterior margin more than 10% of TL); relatively tall, erect dorsal fins with angular apices; 43–49 tooth rows on upper
jaw; a yellowish-brown body with large, diffuse-edged, rusty-brown spots; and an extremely faint, collar-like saddle over
the gill region. A key to species is provided.
