Short Description
Original diagnosis after ASCHLIMAN, EBERT & COMPAGNO, 2010 [10243]: Distinct from congeners by exhibiting spatulate distal ends of the anterior pelvic lobes (wider tip in C. cadenati, tapering in others); dorsal mid-disk and tail with continuous semiparallel rows of thorns in adults (mid-disk lacking thorns in C. rugosa, thorns present on midline in others); claspers with small, flattened process (boss) on accessory terminal 2 cartilage and blind-ended sac with posterior opening at the distal end of the clasper (sentina), both unique within genus to C. hulleyi (Hulley, 1970, 1972); six interdorsal thorns (absent in C. durbanensis, two in C. parcomaculata [5triangularis], four in C. poeyi, one in C. rugosa, many in C. atlantis). Cruriraja hulleyi is further distinguished from congeners by the following combination of characters: interdorsal distance greater than half, and not exceeding, dorsal-fin base length (interdorsal distance at least 1.5 times dorsal-fin base length in C. atlantis, half or less dorsal-fin base length in C. parcomaculata); outer lateral margin of clasper dorsal marginal cartilage elongated and bluntly rounded (also in C. parcomaculata, but truncate in C. rugosa); proximal margin of dorsal terminal I cartilage forms a point (also in C. parcomaculata, but a series of points in C. rugosa); distal point (eperon) of ventral terminal cartilage relatively narrow and claw-like (bifurcate in C. parcomaculata, expanded in C. rugosa); ventral surface of clasper lacks dermal denticles (present in C. parcomaculata).
