description
Description. Morphometric data summarized in Table 3. Body elongate, slightly compressed. Trunk and caudal peduncle progressively more compressed towards caudal fin. Body profile between snout and dorsal-fin origin slightly convex. Largest recorded size 95.8 mm SL. Head depressed; snout rounded in dorsal view. Mouth slightly inferior; lower lip laminar with deep median notch; upper barbel passing base of pectoral fin; lower barbel reaching base of pelvic fin. Opercle and interorpercle partially exposed. Eyes small, laterally placed; infraorbital bones comparatively small. Coracoids highly developed and exposed on ventral surface, usually overlapping in midline even in females. Upper lateral series with 26 - 27 scutes, 22 - 23 in lower series. Three to 7 azygous plates between dorsal and adipose fins. Lateral line sensory canal reduced to one single scute of upper lateral series. Dorsal fin with strong spine, approximately half length of longest branched ray; spine followed by one unbranched and seven branched rays. Pectoral fin with pungent spine and 8 - 10 branched rays; spine with stronger odontodes anteriorly and small retrorse hooks posteriorly. Pectoral spine of fully develope

diagnosis
Diagnosis. Interopercle exposed on the ventral surface of head as a small roundish plate below the opercle. This species is further distinguished from H. littorale by having the coracoids extremely developed on the ventral surface; and from H. punc tatum by possessing a deeper caudal peduncle (17.4 - 19.5 % SL, vs. 14.3 - 17.2, in specimens larger than 55.0 mm SL).

discussion
Comments. Hoplosternum magdalenae occurs west of the Andes, in the Lago Maracaibo basin in Venezuela, and in the drainages of Río Sinu and Rio Magdalena in Colombia (Fig. 4). This region is separated by the Sierra de Abibe and Serrania de las Palomas from the Rio Atrato basin, where H. punctatum occurs.
