All Dipturus Species: Snout very long and pointed. Anterior disc margins deeply concave. A theoretical line from snout tip to pectoral wing tip not touching front margin of disc; internasal width usually less than 70% of the distance from one nostril to snout tip. Thorns on disc usually absent, except for head thorns in small juveniles and alar thorns of mature males.
Underside of disc more or less dark, with mucus and sensory pores marked as black dots and/or dashes; sometimes hard to see in very dark-bellied species or under black mucus coverage, but pores also marked black on upper side and well visible on nape and snout.
Dipturus teevani
Unique Characters: Tip of snout firm; rostral cartilage moderately stout to stout. Anterior pectoral-fin rays distinctly separated from tip of snout. Snout moderately elongated to distinctly elongated, anterolateral margin of disc concave (line connecting tip of snout to anterior aspect of lateral corner of disc free of disc). Ampullar pores on ventral surface of disc generally darkly pigmented (FAO 2013).
Pale brown dorsally. Creamy to dusky ventrally. Dorsal and caudal fins black. Snout very long, pointed. Middle anterior margins of pectoral fins concave. Trailing tips of pectoral fins slightly concave. Dorsal fins connected at base. Few thorns around eyes. Single row of thorns on tail (Kells and Carpenter 2011).
