--------------------------------------------
Description
Dorsal spines (total): 4-5; Dorsal soft rays (total): 26-28; Anal spines: 3-4; Anal soft rays: 11-14; Vertebrae: 27. Body very deep, broadly rounded below dorsal-fin rays, snout slightly elongate, robust in adults, lips and chin with dense ‘whisker-like’ villi, those on chin very long and sometimes divided; dorsal fin tall, sail-like with a convex posterior margin; dorsal spines stout, progressively increasing in length; anteriormost dorsal-fin rays much longer than posteriormost fin spine. Max length : 90.0 cm TL. Depth range: 18 - 193 m.
Color
Five dark bands on the body, and yellow dorsal, anal and caudal fins.
Etymology
Evistias: from Greek prefix, eû = well + from Greek, histion = sail. In reference of its spinous dorsal.
acutirostris: from Latin, acutus = sharp + from Latin, rostrum = snout.

Biology
Benthopelagic over reef and sand. Found in pairs or small groups in deep rocky drop-offs.
Similar species
Histiopterus typus (Temminck & Schlegel 1844) - Reported from Red Sea, Indo-West Pacific: East and South Africa, Comores and Réunion (western Mascarenes) east to Philippines, north to southern Japan, south to northern Australia. Differs from the similar Histiopterus typus in having a deeper, striped body, and short dorsal and anal-fin spines (vs. third and fourth dorsal, and third anal-fin spines elongate in Histiopterus).
