<paragraph id="F46A5199627169F1A3A432C5DF25A232" pageNumber="8">Description: A member of the Hypostominae: Ancistrini. Morphometrics in Table 2. Body low, narrow, and elongate. Body depth increases curvilinearly from snout tip to origin of dorsal fin, decreases to near end of caudal peduncle, and then increases at a steep angle until caudal fin. Ventral surface flat. Body widest at insertion of pectoral fins, narrowest at end of caudal peduncle. Snout rounded. Caudal peduncle oval in cross section with dorsal and ventral surfaces flat.</paragraph>

<paragraph id="DCBC6584190B214BECC639F72819C170" pageNumber="8">Dorsal margin of orbit forming ridge higher than interorbital space. Dorsal surface of head between orbits concave laterally and convex medially. Supraoccipital pointed posteriorly; point of supraoccipital slightly raised and with odontodes slightly larger than those of surrounding bones and plates. Following head bones supporting odontodes: infraorbitals, frontal, nasal, pterotic-supracleithrum, and supraoccipital. Preopercle and opercle rarely supporting odontodes. Posterodorsal margin of opercle often covered by plate.</paragraph>

<paragraph id="C1723F392B34199AC6AF9838262848DB" pageNumber="8">Lower lip wide, covered with short, wide papillae. Upper lip narrow, spotted ventrally, and with very small papillae posteromedially and larger, wider papillae anteriorly and laterally. Only maxillary barbel present, typically reaching about three quarters of way from its origin to gill opening. Some individuals with one or both barbels bifurcated or trifurcated, split barbels are shorter than unsplit barbels. Mouth with small, narrow buccal papilla. Iris with small dorsal flap, not reaching ventral to center of pupil.</paragraph>

<paragraph id="44270EFD15FC3B6D725AAC33E5F272DB" lastPageNumber="9" pageNumber="8">Usually 27 lateral plates (one of 14 individuals with 26 and one with 28). Plates unkeeled. Five rows of plates on caudal peduncle. Plates covering almost all surfaces of body except for anterior margin of snout and between mouth and pectoral girdle. Abdominal plates variable. Most individuals with some small, deeply embedded plates ventral to pectoral girdle, medially on abdomen, ventral to pelvic girdle, near anus, and along sides; however, any abdominal area may be naked. Extent of abdominal plating only partially correlated with size, most small individuals with fewer plates, but some adults with few plates on abdomen.</paragraph>

<paragraph id="EE5CBA1412FD501C4A8F22FC167B3B7E" pageNumber="9">24-53 (mode = 48) evertible cheek odontodes Longest evertible cheek odontode does not reach posterior to cleithrum. Evertible cheek odontodes supported by plates than can be everted to approximately 90° from the head. Hypertrophied cheek odontodes relatively weak. Slightly longer odontodes present along dorsal-, adipose-, and pectoral-fin spines; largest individual examined with modestly hypertrophied odontodes at tip of pectoral-fin spine.</paragraph>

<paragraph id="11C4192ECAEBCA71B983C83D2DE667C2" lastPageNumber="10" pageNumber="9">Coloration: In life, the base color is light tan (almost yellow), tending to orange on the fins (Fig. 1). In alcohol, the base color is darker tan (Fig. 3). Small- to medium-sized dark spots on the head becoming much larger posteriorly; corresponds with decrease in numbers of rows of spots. Size of spots varies, even between specimens collected together, but spots always largest on caudal peduncle and fin. Dorsal-fin spine either without spots or spots present distally. Dorsal fin with spots centered on the membranes, rays typically without spots; dark wash present between dorsal-fin spine and first ray and between the distal branches of the first ray; dorsal fin generally with a black margin. Adipose fin with spot present on preadipose plate and one or two large spots along spine; adipose-fin membrane mottled. Spots on caudal fin largest on body, often combining to form bands (particularly ventrally); caudal-fin spots centered on fin rays; spots present along dorsal margin of dorsal and ventral caudal-fin spines, but ventral margin of ventral caudal-fin spine tan. Pectoral fin spots smallest, centered on either side of the pectoral-fin rays and dorsally along the pectoral-fin spine; spots fade distally. Pelvic fin with large spots dorsally, centered on rays and spine, spots fading posteriorly and distally. Anal fin spotted randomly with spots centered over membranes. Ventral surface behind mouth much lighter than sides, occasionally with slight mottling. Upper lip with small dark spots. Barbels mottled. Eye with dark spots dorsally, mottled ventrally.</paragraph>

<paragraph id="728137FE7AB7C87DFE0C9165EF8609F3" pageNumber="10">Considerable ontogenetic change observed in coloration (Figs. 3 & 4). The smallest individual examined with mottled head and spots that appear to form dorsal saddles posteriorly; large spots present on all fins. Slightly larger individuals with spots on the head, but posterior body spots still forming saddles; dorsal and caudal fins with bands. As individuals grow, the spots become more numerous and the relative size of the spots decreases.</paragraph>

Usually in runs and riffles, but small individuals may be found hidden in the holes of lateritic rocks in pools. Most specimens I collected were collected at night. The largest individual was captured in a gill net in the main stem Essequibo and it appeared to be moving from deeper water into the shallows where there were exposed boulders.</paragraph>

Color and meristics did not vary significantly among populations. Type specimens were restricted to the Essequibo River drainage because future effort might determine that the three known populations (Essequibo, Negro, Orinoco) should be separated.</paragraph>
