Fig. 1. a in Color pattern variation in Cichla temensis (Perciformes: Cichlidae): Resolution based on morphological, molecular, and reproductive data

Fig. 1. a) Four defined color pattern grades in Cichla temensis used to group live specimens in the field. Specimens within each grade occur along a continuum of color and pattern variation. Grades 1 and 4 represent the extremes of variation. The more brightly colored Grade 4 (specimen TL = 548mm) variant is known as the three-barred peacock or tucunaré açu in Brazil. At the other extreme, Grade 1 (specimen TL = 541mm) is known as the speckled peacock or tucunaré paca and is dark and comparatively non-descript. Grade 2 (specimen TL = 613mm) and Grade 3 (specimen TL = 585mm) represent transitional degrees of variation between the extremes of paca and açu. All variant grades were collected in both Region 1 and Region 2 (Fig. 2); b) Cichla monoculus was collected in Region 1 (specimen TL = 382mm) and displays a pattern of bars 1, 2 and 3 similar to, but shorter than those of C. temensis without postorbital markings but with an abdominal bar; c) Cichla orinocensis was collected in Region 2 (specimen TL = 412mm) and is differentiated by three ocellar marks in place of vertical bars 1, 2 and 3. Postorbital markings are absent.
