Body elongated and cylindrical. Head considerably depressed, not elongated. Eyes large, horizontally oval; spiracle large, oblique, located just behind eye. Snout long, flattened, surrounded with saw-like teeth. Mouth short and transversely curved. Pair of barbels present, located closer to mouth than rostral tip. Teeth on rostrum sharp with three distinct sizes; teeth on both jaws small; rows of teeth on upper jaw 35. Dorsal fins moderately large, fully erect, and of similar sizes; first dorsal fin originating posterior to rear tip of pectoral fin; second dorsal fin originating far beyond rear tip of pelvic fin. Anal fin absent. Pectoral fins extremely enlarged; posterior margin slightly concave. Pelvic fin same size as dorsal fins, originating posterior to rear tip of first dorsal fin; posterior margin straight. Caudal fin long, asymmetrical; subterminal notch on upper lobe deep; posterior tip angular. Claspers short and broad. Gill openings small, similar in sizes, with five gill slits on both sides.

Color of fresh specimen. Body and head above uniformly dark brown; underside lighter brown; rostrum brown with two longitudinal lines of darker color; pectoral- and pelvic- fin bases relatively darker brown, lightening towards rear end; no spots or distinct markings.

Remarks.

Pristiophorus lanae was originally described based on specimens collected from various locations in the Philippines, including Batangas, Camarines Sur, Cebu, and Marinduque, at depths ranging from 229 to 593 m ( Ebert and Wilms 2013). Additional reports have since been made from Panay Island ( Koeda and Manjaji-Matsumoto 2017; Weigmann et al. 2020; Leeney et al. 2024; this study). This species is endemic to the Philippines, with the largest known specimen measuring 900 mm TL, as reported by Weigmann et al. (2020). The identification of the collected specimen was verified through its COI sequence data, which is identical with the other sequence of P. lanae (Fig. 3 View Figure 3 ).
