-- Reference: AHLSTROM et al. (1984 C); LARA (2006);

•  Arnoglossus sp. The body is quite elongate.The second dorsal ray can be very elongate and ornamented.The pigmentation is very prominent for this genus and consists of melanophores above the brain, ventrally on the gut, at the dorsal surface of the gas bladder, along the dorsal and ventral midline and between the eyes. Some species have complete or partial bars at the tail region.The pigmentation in the studied specimens was clearly developed on the gas bladder, along the dorsal and ventral midline of the body (at the bases of the medial fins) and they had a partial bar at the tail region (Figure 72). Number of vertebrae ranges from 37 – 48. Arnoglossus develop scale spines.

-- Reference: AHLSTROM et al. (1984 C); NIELSEN (1986);

-- Reference material: 9 specimens; 04/99: S6 (P855956); 05/99: S1 (P855955); 03/02: S2 (P855957); S4 (P855951-954); S19 (P855949-950);

-- Distribution: Larvae were found during winter and spring only at epipelagic stations southeast of Fuerteventura during the night in depth ranges of 13 – 139 m. Only one specimen was caught in late spring far east of Fuerteventura at a depth of 38 – 40 m also during the night.

•  Arnoglossus imperialis Meristics: Dorsal rays:

95 – 106

Anal rays:

74 – 82

-- Morphology: The body is rather elongate.The lower eye is more anteriorly positioned than the upper, when migrated to the adult position and both eyes are separated by a bony bridge in adults. The species identification was done only by meristic counts.

-- Pigmentation: The pigmentation follows the prominent larval pattern for that genus, with a partial bar at the tail region.

-- Reference: NIELSEN (1986);

-- Reference material: 4 specimens; 04/99: S16 (P855947); 05/99: S1 (P855945); 03/02: S15 (P855946); S19 (P855944);

-- Distribution: In winter a specimen was caught at an epipelagic station southeast of Fuerteventura at a depth of 30 – 99 m at daytime. In spring larvae occurred at a neritic station southwest of Gran Canaria at 18 – 61 m depth during the night and at an epipelagic station far east of Fuerteventura at a depth of 38 – 40 m also during the night.
