“…These body shape differences are remarkably congruent with the observed, but shallow, population-level differentiation within this species. This pattern of low intraspecific genetic divergence is also observed in other Central American cichlids (López-Fernández, Winemiller, & Honeycut, 2010;McMahan et al, 2010). Additional material of V. melanura from rivers in the Caribbean slope would aid in corroborating this hypothesis.…”

“…A sequence was available from GenBank for an individual from Río Belize, and material recently obtained by field collections from water bodies in the Petén-Lake district in Northern Guatemala, as well as portions of the Río Usumacinta basin including Río La Pasión, were sequenced as part of this study (Table 2). Primers and molecular methodology followed McMahan, Geheber and Piller (2010). Sequences were aligned by eye and a Parsimony analysis was implemented in PAUP* (Swofford, 2002) also following procedures of McMahan et al (2010).…”

Vieja melanura is a Neotropical cichlid occurring in the Petén-lake district systems of Guatemala, as well as the Río Grijalva-Usumacinta basin, and other systems in Southern México, Belize, and Guatemala. A caudal stripe, extending forward from the caudal peduncle, is characteristic of this species. This stripe is sloped downward in nearly all individuals of V. melanura, but the degree of the slope is highly variable throughout its range. The slope and shape of the stripe has previously been used in diagnosing and differentiating between species of Vieja. The purpose of this study was to use objective methods to investigate morphological variation in the caudal stripe and body shape throughout the range of V. melanura. We studied geometric morphometric analyses of body shape and empirical measurements of the slope of the caudal stripe in 215 specimens of V. melanura. We also used the mitochondrial cytochrome b marker to study population level patterns within V. melanura. Results from our analyses showed significant geographic variation in body shape and patterns of coloration with little mitochondrial phylogeographic structure. These patterns likely correspond to differences in riverine habitats throughout the species’ distribution. In conclusion, these results can be used to inform other studies of color and shape variation as it applies to taxonomy and systematics.

Based on a combination of intensive literature review, electronic database searches, re-identification of museum specimens and fieldwork, we hereby provide an updated checklist of the freshwater fishes of continental and insular Costa Rica. This checklist, systematically arranged at the ordinal and familial level, includes nomenclatural revisions, distributional information, and when appropriate, cross-references on the basis of Bussing (1998). According to our results, the native Costa Rican freshwater fish fauna is composed by 250 species, divided into 119 genera, 49 families and 19 orders; increasing in 108 the number of species originally reported by Bussing (1998). By far, the vast majority of these species, according to their supposed tolerance to salinity, are peripheral (63.2%), followed by secondary freshwater fishes (23.6%); only 13.2% are primary freshwater fishes. 24 species in this checklist appear to be endemic to Costa Rica. In addition to the native fauna 8 exotic species are reported.

“…Different phylogenetic studies of Cichlinae (neotropical members of Cichlidae) use various generic-level designations for species, such as the use of 'Heros' instead of 'Cichlasoma' in Říčan et al (2013) and other studies. All recent large-scale generic-level taxonomic changes proposed have only been topologically-based, thus renaming clades based on the oldest available generic name within that clade (McMahan et al 2010, López-Fernández et al 2010. The purpose of this study is to generate a phylogeny of the herichthyin cichlids with as complete a taxonomic and molecular loci sampling scheme as possible, and to revise the generic-level taxonomy of these cichlids accordingly based on unique combinations of diagnostic features.…”

In recent years great strides have been made for improving our understanding of the evolutionary relationships among neotropical cichlids, particularly within the clade Heroini and its crown clade the herichthyins. Most phylogenetic studies have largely converged on congruent topologies for relationships among species and major lineages within the herichthyins. One major aspect missing from previous studies of these cichlids is a formal taxonomic revision, including the redefining of genera. Based on analysis of 52 species and three mitochondrial and two nuclear loci, we generate a Bayesian phylogeny for the herichthyin cichlids, and formally revise the taxonomy for genera within this clade using morphological features. Eight new genera are recognized and a key to all 16 genera of herichthyin cichlids is also presented.Key words: cichlid, revision, Mexico, Central America, morphology ResúmenGrandes pasos se han dado en años recientes en la mejora de nuestro conocimiento de las relaciones evolutivas entre ciclidos Neotropicales, particularmente dentro del clado Heroini. En el clado corona de Heroini están los herichthyins. Los estudios filogenéticos más recientes, han coincidido ampliamente con topologías congruentes para definir las relaciones entre especies y linajes mayores en este clado. La falta de una revisión taxonómica formal de estos ciclidos, es un gran vacío que han dejado estudios anteriores, incluyendo la redefinición de géneros. Basados en un muestreo taxonómico completo y un set de datos molecular casi-completo, nosotros generamos una filogenia para el grupo de ciclidos conocido como los herichthyins, y revisamos formalmente la taxonomía de cada género en este clado usando caracteres morfológi-cos. Una clave para los 16 géneros de ciclidos herichthyinos es también presentada.
