“…This supports an adaptive basis for a trade-off between those geophagine taxa feeding primarily from the substrate and those feeding above it. The Crenicichla clade encompasses 44 per cent of the species diversity of clade CAS and 35 per cent of the diversity of all geophagine cichlids, exhibits ecomorphological characteristics nearly unique among South American Neotropical cichlids and possesses as much body size and morphological disparity as many other Neotropical cichlid genera combined [18,20,21]. Evolution of the unique combination of feeding biomechanics probably permitted the evolution of a novel feeding strategy (fast-burst predators) among the Geophagini, allowing opportunities for rapid diversification of ecomorphological traits within this niche [51].…”

“…org), and similar to clade GGD includes substrate-sifting benthivores in the genera Satanoperca and Acarichthys [20], as well as numerous (greater than 90) dwarf species, such as those within the genus Apistogramma, living in leaf litter habitats and probably picking benthic invertebrates from the substrate [19,20]. Clade CAS however, also includes Crenicichla (which includes within it the genus Teleocichla, see López-Fernández et al [17]; henceforth, the 'Crenicichla clade'), which comprises 90 described and numerous undescribed species of elongate-bodied predators feeding on fishes and invertebrates [21,22].…”

Diversity and disparity are unequally distributed both phylogenetically and geographically. This uneven distribution may be owing to differences in diversification rates between clades resulting from processes such as adaptive radiation. We examined the rate and distribution of evolution in feeding biomechanics in the extremely diverse and continentally distributed South American geophagine cichlids. Evolutionary patterns in multivariate functional morphospace were examined using a phylomorphospace approach, disparity-through-time analyses and by comparing Brownian motion (BM) and adaptive peak evolutionary models using maximum likelihood. The most species-rich and functionally disparate clade (CAS) expanded more efficiently in morphospace and evolved more rapidly compared with both BM expectations and its sister clade (GGD). Members of the CAS clade also exhibited an early burst in functional evolution that corresponds to the development of modern ecological roles and may have been related to the colonization of a novel adaptive peak characterized by fast oral jaw mechanics. Furthermore, reduced ecological opportunity following this early burst may have restricted functional evolution in the GGD clade, which is less species-rich and more ecologically specialized. Patterns of evolution in ecologically important functional traits are consistent with a pattern of adaptive radiation within the most diverse clade of Geophagini.

“…These Uruguayan species are traditionally included in the C. missioneira and C. scottii species groups (Lucena & Kullander, 1992; extended by Kullander et al, 2010), and differ from the herein discussed taxa in a combination of color-pattern and meristic characters (Lucena & Kullander, 1992). The relationships of the new species with the Paraná River Crenicichla is also confirmed with analysis of molecular data (mitochondrial genes ND2 and cytochrome b) which included all at-present-known species from the Misiones province (Piálek et al, in prep.).…”

A new species of Crenicichla, C. ypo, is described from the Arroyo Urugua-í, a left-hand tributary of the middle Paraná River, Misiones province, Argentina. The new species is recognized by 6 to 8 irregular blotches along the upper lateral line, absence of scattered dark spots on flanks, low number (47-55) of E1 scales, and a slightly prognathous lower jaw. Females have a distinctive coloration of the dorsal fin, with a wide black longitudinal stripe on the distal portion with an equally wide red stripe below it. Una nueva especie de Crenicichla, C. ypo, es descripta de la cuenca del arroyo Urugua-í, tributaria de la margen izquierda del río Paraná medio, provincia de Misiones, Argentina. La nueva especie es reconocida por tener 6 a 8 manchas irregulares sobre la línea lateral superior, ausencia de pequeñas manchas oscuras dispersas sobre el flanco, bajo número (47-55) de escamas en la serie E1 y la quijada inferior levemente prognata. Las hembras tienen una coloración distintiva en la aleta dorsal con una banda ancha negra en la porción distal y otra roja del mismo ancho por debajo de esta.

“…Phylogenetic relationships within Crenicichla are still controversial. Based on a mitochondrial cytochrome b gene analysis, Kullander et al (2010) reported the monophyly of some previously defined Crenicichla species groups that were recognized based on morphology. Kullander (1990) presented a discussion on small species of Crenicichla from the Amazon basin.…”

A new species of Crenicichla is described from the middle rio Xingu and tributaries, upstream from Volta Grande do Xingu. The largest specimen measured 47.8 mm SL. The new species can be distinguished from all other Crenicichla species by the combination of the following character states: presence of serrae on supracleithrum (diagnostic of Crenicichla wallacii species group), large caudal blotch centrally located on caudal lateral line (shared with C. urosema and C. virgatula), vertical dark stripes on the caudal fin and up to three series of teeth on premaxilla and maxilla (vs. more than four series of teeth). The new species described herein is the eleventh species of Crenicichla listed from the rio Xingu basin. Similarities of color pattern among small species of Crenicichla is discussed.Uma nova espécie de Crenicichla é descrita para o médio rio Xingu e seus afluentes acima de Volta Grande do Xingu. O maior espécime mede 47,8 mm CP. A nova espécie pode ser distinguida de todas as outras espécies de Crenicichla pela seguinte combinação de caracteres: presença de serrilhas no supracleitro (diagnóstico das espécies do grupo C. wallacii), ampla mancha caudal centralmente posicionada sobre a linha lateral caudal (compartilhada com C. urosema e C. virgatula), série de faixas verticais escuras entre os raios da nadadeira caudal e até três séries de dentes no premaxilar e dentário (vs. mais de quatro séries de dentes). A nova espécie aqui descrita é a décima primeira espécie de Crenicichla listada para a bacia do rio Xingu. Semelhanças no padrão de coloração entre as espécies de Crenicichla de pequeno porte são discutidas.
