Etymology: Parmaturus: parma (L.), from parme (Gr.), small shield; oura (Gr.), tail, presumably referring to upper edge of caudal fin “armed with modified” scales (per Garman 1913). (See ETYFish); albimarginatus: albus (L.), white; marginatus (L.), bordered, referring to broad white margins on posterior fins. (See ETYFish).

Morphology | Morphometrics
This scyliorhinid catshark is characterized by the following: a soft body with velvet-like
skin of large tricuspidate denticles; color plain pale to medium brown; posterior margins of the dorsal, caudal and anal-fins are distinctly white-edged; upper and lower anterior caudal fin margins with pronounced caudal crests, the denticles on crests are greatly enlarged; teeth are mainly tricuspidate with greatly elongate median cusps, in 92 rows in both jaws; the first dorsal fin is slightly behind middle of back, the pelvic fins slightly in front of mid-body, prepelvic
length 47% TL; vent at mid-length, pre-vent length 50% TL; relatively short snout, prenarial length 3.7% TL; short mouth, length 3.7% TL; short labial furrows, 1.7-2.0% TL, lower furrows subequal in length to upper furrows; head depressed and is shorter than abdomen, length 19.2% TL, pectoral-pelvic length 24.8% TL; second dorsal fin is larger than first, anterior margins of first 8.7% and second dorsal fin 10.4% TL; subterminal caudal lobe relatively small, subterminal margin length 3.3% TL, terminal margin length 3.8% TL; 43 monospondylous centra; 95 precaudal centra, 136 total (Ref. 74543).
