Body covered by plates, except area around anus, region overlying lateral opening of swimbladder capsule, area between lower lip and pectoral girdle, and area around fin bases. Ventral portions of cleithrum and coracoid completely exposed and supporting odontodes. Abdomen covered by 2-6 (mean 4) transversely elongate lateral abdominal plates; middle abdominal plates 1-6 (mean 4). Single, large preanal plate between pelvic fins. Anal tube slightly right turned. Total vertebrae 26; ribs 3, beginning on tenth vertebral centrum, in addition to large rib on sixth centrum. +Dorsal fin I,7, its origin at vertical through middle of pelvic fin. Dorsal-fin spinelet absent. Pectoral fin I,6, with small axillary slit in skin behind fin insertion. Pectoral-fin spine with small serrae composed of retrorse, conical, acute teeth along posterior margin, one per ray segment. Serrae more conspicuous in younger specimens, absent in larger. Pectoral fin reaching to vertical through posterior third of pelvic-fin unbranched ray. Adipose fin absent. Pelvic fin i,5, short, with robust thickened first ray shorter than two first branched rays. Odontodes on pelvic-fin unbranched ray turned and strongly pointing mesially. Anal fin i,5; first analfin pterygiophore exposed in front of unbranched fin ray. Caudal fin i,14,i, forked, upper and lower lobes equal. + +Color in alcohol. +Ground color of dorsal surface of head and body tan to light brown. Dark brown melanophores on head more densely concentrated on compound pterotic, parietosupraoccipital, frontals, postrostral plates, and anterior surface of upper lip. Longitudinal dark brown lateral stripe on midlateral surface of head and body; stripe beginning laterally on snout tip, crossing eye, and continuing to end of caudal peduncle. Brown melanophores arranged in four or five inconspicuous dorsal saddle-like blotches; one anterior to dorsal fin, one on posterior portion of dorsal fin, two or three at caudal peduncle. Ventral surface of body mostly unpigmented except for ventral portion of snout plates, canal-bearing cheek plate, and lateral portions of caudal peduncle. Dorsal and pectoral fins with 5-6 dark brown spots, continued as 3-4 irregular bands on branched rays. Pelvic fin with 1-2 and anal fin with 2-3 such spots.

Body covered by plates, except area around anus, region overlying lateral opening of swimbladder capsule, area between lower lip and pectoral girdle, and area around fin bases. Ventral portions of cleithrum and coracoid completely exposed and supporting odontodes. Abdomen covered by 1-3 (mean 2) small, ovate lateral abdominal plates; middle abdominal plates absent. Single, small preanal plate between pelvic fins. Anal tube slightly right turned. Total vertebrae 26; ribs 7, beginning on eighth vertebral centrum, in addition to large rib on sixth centrum. +Dorsal fin I,7, its origin at vertical through middle of pelvic fin. Dorsal-fin spinelet absent. Pectoral fin I,6, with small axillary slit in skin behind fin insertion. Serrae absent along mesial margin of pectoral-fin spine. Pectoral fin reaching to vertical through midpoint of pelvic-fin unbranched ray. Adipose fin absent. Pelvic fin i,5, short, with robust thickened first ray shorter than two first branched rays. Odontodes on pelvic-fin unbranched ray turned and strongly pointing mesially. Anal fin i,5; first anal-fin pterygiophore exposed in front of unbranched fin ray. Caudal fin i,12,i, forked, upper and lower lobes equal. + +Color in alcohol. +Ground color of dorsal surface of head and body tan to medium brown. Dark brown melanophores on head more densely concentrated on compound pterotic, parieto-supraoccipital, frontals, postrostral plates, anterior surface of upper lip, and posterior and mesial portions of naris flap. Melanophores on body concentrated on predorsal area and lateral stripe. Longitudinal dark brown lateral stripe on midlateral surface of head and body; lateral stripe from snout tip partially covering ventral half of eye and continuing to end of caudal peduncle. Light brown melanophores arranged in four inconspicuous dorsal blotches; one anterior to dorsal fin, one on posterior portion of dorsal fin, two at caudal peduncle. Posteriormost plates of both dorsal and ventral series of lateral plates less pigmented. Ventral surface of body mostly unpigmented except for ventral portion of snout plates, canal-bearing cheek plate, lateral region of pectoral girdle, and lateral portions of caudal peduncle. Dorsal and pectoral fins with 5-6 dark brown spots, continued as irregular bands on branched rays. Pelvic fin with 3-4 and anal fin with two spots.

An adjective. + + + + +Conservation status. + +Leptotocinclus ctenistus + +is relatively frequent and abundant in the tributaries of the rio Solimões and rio Negro, with an EOO of approximately +128,000 km +2. As it is widespread and no eminent threats are detected, + +L. ctenistus + +can be categorized as Least Concern (LC) according to the International Union for Conservation of Nature (IUCN) categories and criteria ( +IUCN Standards and Petitions Subcommittee, 2016 +). + + + + +Multivariate comparison. +General morphological differences between + +Leptotocinclus ctenistus + +and + +L +. +madeirae + +were investigated using a Principal Components Analysis. The resulting first principal component included an expressive proportion of the total variance (57.3%), but all variable loadings were positive and varied little in magnitude, suggesting that it represents a general size factor. Plots of factor scores of principal component 2 +vs +. 3 grouped specimens into two slightly overlapping clusters ( +Fig. 17 +). PC2 and PC3 included 17.3% and 7.0% of the total variance, respectively. Measurements with heavier loadings on PC2 were pectoral-pelvic fin distance (0.29), postdorsal length (0.20), caudal-peduncle width (-0.45), and naris diameter (-0.65); on PC3 heavier loadings were dorsal-fin base length (0.34), caudal-peduncle width (0.37), naris diameter (-0.27), and suborbital depth (-0.60).
