Description: A medium sized Ancistrus, body broadest anteriorly, greatest body width just posterior to opercles, then narrowing progressively to end of caudal peduncle. Head and body depressed, greatest body depth between level of pectoral fin insertions and dorsal fin origin. Caudal peduncle deep, robust, compressed posteriorly. Dorsal profile of head ascending steeply in convex arc from tip of snout to just posterior of orbits, ascending in straight line to posterior tip of supraoccipital, then descending to dorsal-fin origin. From the dorsal-fin origin descending in a slight convex arc to just posterior of dorsal-fin base, then straight to caudal fin. Ventral profile flat to slightly convex from tip of snout to pelvic-fin insertions. Abdomen flat to slightly concave to pelvic-fin insertions, from there, straight to slightly convex and sloping gently ventrally towards caudal fin. (Souza, LS de. et al). Colouration: Dorsum mottled dark and light brown with small white spots on the extent of the body. Body posterior to dorsal-fin origin equally spotted, and base colour is dark and light brown. Preadipose plate and vestiges of adipose-fin spine outlined in yellow. Sides with irregular light and dark spots. Ventrum of body with light brown base colour and tightly spaced small white spots. Oral disk and adjacent area on chest pink to whitish. Fin membranes lightly pigmented, greyish, but spines and rays tan in colour with spots on all fins. Dark interspaces on the head, anterior body, and abdomen usually greater than half the width of the spots. Aquarium Care: The Ancistrus genera make good community fish where they do not grow too big for the aquarium. Some species have different requirements in the aquarium so best to read up on the species you have whereas if they need higher oxygen requirements or not, or if they prefer cooler waters if they originate from the southern parts of South America against the species from further up north. Diet: Vegetable foods such as cucumber and courgette and also tablet and meaty foods. Reproduction: The female lays her eggs in caves or crevices... that the male has chosen and cleaned.... as a cluster. The male usually then guards the eggs after ejecting the female. The fry then cling to the sides of the cave and when they use up their yolk sac, which is around the four to seven day period, they will be ready to feed on infusuria, vegetable matter, brine shrimp naupli or micro worms. In a community tank a few will survive if enough hiding places are afforded to them. Etymology: The Portuguese word "saudades" is used to express a deep longing or profound melancholy attached to a person, place or experience. It has a deeper tone and meaning than a direct English translation and reflects the lead author’s connection to her Brazilian heritage and her nostalgia for field work in remote wilderness areas that yielded these museum collections. (Souza, LS de. et al).

Loricariidae

South America: Has a distribution that matches the upper portion of the Proto-Berbice River drainages: Takutu, upper Ventuari, upper Caura, and upper Caroni river drainages of Guyana, Venezuela, and Brazil. Type locality: restricted to the Takutu drainage of Guyana/Brazil because the Orinoco populations may be distinct.
