Predorsal

Pectoral fins iii,12; scales 4/36/3', 14 around caudal peduncle; 7 premaxillary teeth, the inner one enlarged; depth 5.1; head 3.6; body width 1.65-1.70 in body depth (predorsal 1.14-1.18; about 10 transverse bands) Characidium zebra-group, 6 ex.

The following additional measurements were made: predorsal, preanal, prepelvic and prepectoral lengths are those measured from the anterior point of SL to the anterior basis of the dorsal, anal, pelvic and pectoral fins respectively.

multiradiatus, but can be distinguished by the number of unbranched rays in the dorsal, pectoral and pelvic fins, the number of predorsal scales, body depth, etc.

Origin of dorsal fin above base of fourth lateral-line scale, the predorsal length 2.6 (2.45-2.55) in SL; dorsal spines progressively longer, the first 2.75 (2.7-3.05) in head length; twelfth dorsal spine 1.4 (1.45) in head length; fourth dorsal soft ray longest, 3.15 (1.75-3.4) in SL; origin of anal fin below base of ninth dorsal spine, the preanal length 1.6 (1.6-1.7) in SL; first anal spine 2.45 (2.3-2.6) in head length; second anal spine 1.15 (1.1-1.35) in head length; sixth or seventh anal soft rays longest, 3.35 (3.3-4.45) in SL; caudal-fin length (includes filament of longest ray) 1.85 (1.65-1.9) in SL; caudal concavity 3.2 (2.9-4.5); pectoral-fin length 3.3 (3.1-3.4) in SL; pelvic-fin length 2.6 (2.2-3.0) in SL.

The following morphometric data are given as percentages of the standard length: head length (37.6-40.2); snout length (11.8-13.0); upper jaw length (18.8-23.2); interorbital width (5.9-6.8); eye diameter (9.6); maximum body depth (44.2-49.4); maximum body width (13.8-15.2); predorsal length (36.8-37.4); preanal length (60.9-63.6); prepelvic length (36.141.3); base of dorsal fin (52.5-55.7); base of anal fin (17.8-22.7); caudal-peduncle depth (12.112.6); longest dorsal spine (IV) (16.2-16.6); pectoral-fin length (35.3-38.8); pelvic-fin length (26.8-27.4).

Predorsal scales small, reaching forward to close behind eyes.

The following characters exhibited normal distributions and did not differ significantly in variance between species and were subjected to ANOVA: head length, orbit length, snout length, interorbital width, suborbital depth, gill-raker length, body thickness, pectoral-fin base width, pectoral-fin ray length, caudal peduncle ventral length, predorsal length, spinous dorsal-fin base, soft dorsal-fin base, and counts of lateral-line pores and gill rakers.

Body compressed, head robust; snout blunt, little projecting before eyes (5.7-6.3 in HL), profile almost vertical before eyes, slightly convex from behind eyes to dorsal origin; back slightly elevated; origin of dorsal fin on nape just behind top of gill opening (predorsal length 3.0-3.2 in SL); origin of anal fin slightly behind anus and behind midbody (preanal length 1.8-1.9 in SL).

Disc wider than long, margins of pectoral fins broadly rounded; anterior lobe of pelvic fins slender, pointed; tail longer than disc; snout soft, flexible, especially near tip, internal supporting rostral cartilage slender and weak; teeth small, numerous, 32 rows in upper jaw; interorbital space wide, slightly convex; thorns absent from disc; tail thorns 29, interdorsal thorns 2; dorsal and ventral surface of head and body uniformly covered with small denticles; 2 small, well-separated dorsal fins, about equal in height and length; predorsal vertebrae between pelvic girdle and origin of first dorsal fin about 86.
