“…However, we could not discard the possibility that similar DNA fragment sizes may also present large nucleotide differences. Although mitochondrial DNA sequence analysis has shown a distant relationship between Cynoscion and Stellifer (Vinson et al, 2004), previously published morphometric data (Aguirre and Shervette, 2005) are in accordance with the present results that suggest a closer relationship between these two genera.…”

“…Isopisthus is easily distinguished from typical Cynoscion by having a highly divergent body shape, a greatly expanded anal fin and a gap between the first and second dorsal fins (Chao, 1995;Aguirre and Shervette, 2005). However, Cynoscion analis is morphologically intermediate between typical Cynoscion and Isopisthus (e.g., Schwarzhans, 1993;Aguirre and Shervette, 2005), suggesting that Isopisthus evolved from Cynoscion, with C. analis corresponding to an intermediate form. Thus, placement of the two species of Isopis- thus in a separate genus is not warranted and we suggest that they be included in the genus Cynoscion.…”

“…a. Características taxonómicas: Los peces capturados se identificaron mediante las claves establecidas en la guía para la identificación de especies con fines de Pesca, FAO (Fischer, 1995 También se verificó con información actual de la familia Sciaenidae, sobre la cual existen numerosos estudios sobre su taxonomía tal como los presenta ARAP (2011), quien indica que estos peces son alargados a ovalados, con la base de la aleta dorsal muy larga y una hendidura (o completamente separada en algunas pocas especies) entre las secciones espinosa y suave de esa aleta, Otras características generales incluyen un hocico relativamente romo en la mayoría de las especies; poros muy conspicuos en el hocico y en la mandíbula inferior, una faldeta ósea arriba del opérculo; canales cavernosos sensoriales grandes en la cabeza (Aguirrea & Shervette, 2005).…”
