Overall view of body in Fig. 1. Head broad, moderately depressed and slightly compressed. Snout and anterior profile of head rounded in dorsal view. Eye of moderate size, laterally positioned. Dorsal margin of orbit moderately raised. Greatest body width at cleithrum, narrowing from dorsal-fin region to caudal-fin origin. Dorsal profile of head straight from snout tip to vertical through interorbital region, forming angle of 45° with ventral region of head; slightly convex from that point to dorsal-fin origin; straight from that point to adipose fin and concave from adipose fin to procurrent rays of dorsal fin. Ventral profile almost straight from snout tip to insertion of pelvic-fin unbranched ray; slightly straight from pelvic-fin insertion to first ventral caudal-fin procurrent ray. Caudal peduncle compressed, somewhat ellipsoid in cross section on its whole extension. Plates along the mesethmoid forming a longitudinal bulge from snout tip to nares, more conspicuous in specimens up to 80.0 mm SL ( e.g.NUP 12066). Supraoccipital bone with slightly-developed median ridge; its short posterior process bordered by single plate. Conspicuous ridge originating lateral to nares, passing through supraorbital, and extending along dorsal portion of pterotic-supracleithrum. Opercle moderate in size, with thin skin layer surrounding its edges. Oral disk round, moderate in size; its margins fringed. Lower lip not reaching transverse line through gill openings; ventral surface covered with numerous small papillae decreasing in size distally. Maxillary barbel slightly smaller than eye diameter; mostly free from lower lip. Odontodes present on anterior surface of upper lip, just below snout. Median buccal papilla present and well developed. Dentaries moderate to strongly angled, averaging from 80° to 90° between left and right dentary rami. Teeth viliform, bicuspid with lateral cusp smaller than mesial cusp; crowns bent ventrally. Body covered with five rows of dermal plates with moderately-developed odontodes, except on base of dorsal fin and small naked area on snout tip. Predorsal region with very slight median keel. Dorsal series of plates with very slight keels. Mid-dorsal, median, and mid-ventral series with relatively well-developed keels. Median series bearing continuous lateral line. Mid-ventral series strongly angled from first to fourth or fifth plates. Ventral series without keel, but sharply bent ventrally on caudal-peduncle region. Ventral surface of head covered with platelets, except for the region beneath lower lip. Abdomen covered with minute platelets in specimens larger than 80 mmSL, with exception of very small areas around pectoral- and pelvic-fin insertions and at urogenital opening. Distal portion of pterygiophore exposed.   FIGURE 3.Live coloration of  Hypostomus velhochicoMCNIP 1795, paratype, 125.3 mm SL. Brazil, Minas Gerais State, rio Paraopeba, rio São Francisco basin. Photo: Gabriel Torquato. Dorsal fin II,7, its origin at vertical through midpoint between pectoral- and pelvic-fin insertion, or slightly posterior to that point, first spine present as V-shaped spinelet. Distal margin of dorsal fin straight; tip of last dorsalfin ray almost reaching adipose-fin spine. Adipose-fin spine compressed and slightly curved inward. Pectoral fin I,6, its distal border convex. Pectoral-fin spine slightly curved inward, covered with moderately developed odontodes, more developed on its distal portion, particularly in larger specimens. Tip of adpressed pectoral fin reaching to basal one-third to one-fourth of adpressed pelvic-fin spine. Pelvic fin i,5, its distal border straight to slightly convex; its adpressed unbranched ray surpassing anal-fin origin. Anal fin i,4, its tip reaching the fifth to sixth plate after its origin. Rays of anal fin progressively increasing in length posteriorly, third branched ray usually the longest. Caudal fin i,14,i, its margin falcate, with ventral lobe longer than dorsal.  Color in alcohol.Overall ground color of dorsal and ventral regions of body and fins yellowish-brown ( Fig. 1). Head, trunk and fins covered by well-defined and moderately-set dark brown spots except on lower lip. Spots roundish and homogeneously-sized along longitudinal axis of body, usually slightly smaller than eye pupil. Dark spots sometimes horizontally aligned along each lateral series of plates ( e.g.LBP 8284). Ventral surface of body with conspicuous spots, except in some specimens up to 70 mmSL ( e.g.MCP 16664). All fins with conspicuous dark brown spots, except caudal fin on specimen MCP 33816, 82.6 mmSL. Dorsal fin with spots usually forming four to five transverse rows. Most specimens with five faded oblique dark bars on dorsum, first bar on posterior portion of head, stronger at middle of orbit, second bar at first dorsal-fin branched rays, third bar at last dorsal-fin branched ray, fourth bar at anterior region of adipose fin and fifth at procurrent caudal-fin rays.  Color in life.Color pattern of living specimens similar to preserved ones, except for more brownish background and black and more conspicuous spots ( Fig. 3).  Sexual dimorphism.No sexual dimorphism was observed among the specimens.   Distribution.  Hypostomus velhochicois known from several localities along the rio São Francisco basin ( Fig. 4). The species was found from the upper stretches of the basin as the rio Cipó, a tributary of rio das Velhas in Minas GeraisState; and from the rio Preto, a tributary of the median stretch as the rio Paracatu in Distrito FederalState; to lower stretches of the basin as the rio Verde Grande, rio Coxá basin, as well as in rivers draining to the Sobradinho reservoir, in the BahiaState.  Ecological notes.  Hypostomus velhochicowas found in low current stretches with bottom composed by sand and clay (with predominance of clay). The average width of the river stretches was about 20 meters and depth ranging from 1.0 to 2.0 meters. Margins with arboreal-shrub vegetation typical of Cerrado biome. Currently these banks are usually antropically fragmented. The new species occurred syntopically to  Acestrorhynchus lacustris,  Astyanax fasciatus,  Hypostomus francisci,  Megaleporinus obtusidens,  Megaleporinus reinhardti,  Schizodon knerii, and  Serrasalmus brandtii.   Etymology.The specific epithet,  velhochico, is in reference to the rio São Francisco, tenderly called by locals as “Velho Chico” [Old Chico].
