Etymology: Loricaria: Latin, lorica, loricare = cuirass of corslet of leather; 1706 + Greek, ichthys = fish (Ref. 45335); spinulifera: Derived from the Latin word 'spinula' (a small thorn, spine) and 'fero' (to bear, carry, bring), implying 'bearing little thorns', in reference to the conspicuous thorn-like odontodes on the dorsal and lateral surfaces of the head..

Short description
Khóa để định loại | Hình thái học | Sinh trắc học
Differs from all other members of the genus Loricaria by the possession of the following unique characters: head surfaces with strongly developed crests and predorsal plates with
large thorn-like odontodes; oral papillae situated behind the premaxillary teeth consisting of approximately 20 papillae, all longer than premaxillary teeth, arranged in a dense cluster; plates on the median abdominal area consisting of small round to diamond-shaped plates varying in size and spacing, with pre-anal shield absent or with few small plates distributed along the center and around anterior margin of anus; and dorsal surface of the head consisting of solid dark brown extending from center of orbits to tip of snout with large irregular spots from center of orbits to middle of dorsal fin. Specimens taken from deep channels differ from those collected from shallower depths by having smaller eyes that are more recessed in the orbits and tending to be less boldly pigmented, with dark patterns on the hear, body and fins more diffuse or faded (Ref. 79031).
Facultative air-breathing in the genus (Ref. 126274); Appears to prefer deep channels of large black water rivers. Reportedly collected with the use of bottom trawls at depths from 1.5 to 28 m and at distances of 10 to 750 m from the shoreline, as well as over substrates of sand, mud, and organic debris. Aquatic insect larvae, organic detritus and sand were found in the stomach contents of a single specimen measuring 12.06 cm SL (Ref. 79031).
