FIGURE 1 | Schematic drawing of Myloplus schomburgkii with the landmarks used in the measurements. 1, anteriormost point of the snout. 2, distal margin of the hypurals. 3, dorsal-fin insertion. 4, pelvic-fin insertion. 5, posteriormost point of the opercle, not including opercular membrane. 6, supraocciptal's base. 7, supraocciptal's distal tip. 8, pectoral-fin insertion. 9, anal-fin insertion. 10, distal tip of the longest dorsal-fin unbranched ray. 11, base of the last dorsal-fin ray. 12, anterior end of the adipose-fin base. 13, pectoral-fin distal tip. 14, pelvic-fin distal tip. 15, distal tip of the longest anal-fin unbranched ray. 16, base of the longest ray of the second anal-fin lobe. 17, distal tip of the longest branched ray of the second anal-fin lobe. 18, distal end of the anterodorsal margin of the adipose fin. 19, posterior end of the adipose-fin base. 20, posterior end of the anal-fin base. 21, point of the dorsal profile of the caudal peduncle in which it is closest to ventral profile. 22, point of the ventral profile of the caudal peduncle in which it is closest to dorsal profile. 23, posteriormost point of the eye. 24, middle of posterior margin of the fourth infraorbital. 25, middle of anterodorsal margin of third infraorbital. 26, middle of posteroventral margin of third infraorbital. 27, internal angle of pre-opercle. 28, dorsalmost point of the eye. 29, ventralmost point of the eye. 30, anteriormost point of the eye. 31, distal end of the premaxilla. 32, point in which the head is wider. 33, point in which the caudal peduncle is wider. The ventral keel count comprises prepelvic spines (prPvSp), postpelvic spines (poPvSp), and the paired spines around anus (bISp).
