Etymology: Pristiophorus: pristio-, presumably derived from prio (Gr.), to saw, but treated here as a noun (a saw); phorus, from phoreus (Gr.), bearer or carrier, referring to saw-like snout (note also that pristis is Greek for sawfish) (See ETYFish); lanae: In honor of “shark enthusiast” Lana Ebert (the senior author’s niece) on the occasion of her graduation from the University of San Francisco (her brother is similarly honored; see Rhinobatos austini, Rhinobatidae) (See ETYFish).
Eponymy: Lana Ebert is a marine biologist, shark enthusiast and the niece of senior author David Ebert. [...] (Ref. 128868), visit book page.

Descrição breve
Chaves de identificação | Morfologia | Morfometria
This slender bodied five-gilled sawshark is distinguished from its congeners by the following combination of characters: a narrow, relatively long rostrum, with a pre-oral length 27.5-30.6% TL; pre-barbel length 51-55% of pre-oral length; rostral width at nostrils 4.8-6.1 times pre-orbital length. Barbels located closer to the mouth than to rostral tip. First dorsal fin originates posterior to free rear tip of pectoral fin; lateral dermal denticles are unicuspidate, mostly flat, and imbricated; color uniform dark brown above, lighter below; no bars, blotches or other distinctive markings (Ref. 94800).
Body shape (shape guide): other (see remarks); Cross section: oval.
Inhabits upper continental slopes in tropical waters (Ref. 94800).
