dc:description"FIGURE 1. Diagrammatic representation of scale nomenclature, head markings and lateral bar patterns of Geophagus as used in this paper. Abbreviations are as follows: E 1, first epaxial longitudinal series of scales, used to count number of longitudinal scales; E 6, last epaxial longitudinal series of scales; H 1 – H 5, hypaxial longitudinal series of scales; IOS, infraorbital stripe; MLS, midlateral spot; POM, preopercular mark; ULL, upper lateral line; LLL, lower lateral line; 1 – 7, lateral bars. Scale nomenclature after Kullander (1992, 1996). Infraorbital, preopercular and midlateral black markings are observable both in live and preserved specimens; lateral bar patterns are gener";
