“…Previous studies have suggested that hybridization between the two species is ongoing since the building of canals to extract water out of the basin of the valley which generated novel connections with external rivers (La Bounty 1974;Kornfield & Koehn 1975;Liem & Kaufman 1984). This species lacks the polymorphisms found in H. minckleyi (Miller et al 2005;Oldfield et al 2015).…”

Understanding the origin of biodiversity requires knowledge on the evolutionary processes that drive divergence and speciation, as well as on the processes constraining it. Intraspecific polymorphisms can provide insight into the mechanisms that generate and maintain phenotypic, behavioural and life history diversification, and can help us understand not only the processes that lead to speciation but also the processes that prevent local fixation of morphs. The 'desert cichlid' Herichtys minckleyi is a highly polymorphic species endemic to a biodiversity hotspot in northern Mexico, the Cuatro Ciénegas valley. This species is polymorphic in body shape and trophic apparatus, and eco-morphotypes coexist in small spring-fed lagoons across the valley. We investigated the genetic structure of these polymorphisms and their phylogeographic history by analysing the entire control region of the mitochondrial DNA and 10 nuclear microsatellite markers in several populations from different sites and morphs. We found two very divergent mitochondrial lineages that most likely predate the closing of the valley and are not associated with morphotypes or sites. One of these lineages is also found in the sister species Herichthys cyanoguttatus. Data from neutral microsatellite markers suggest that most lagoons or drainages constitute their own genetic cluster with sympatric eco-morphotypes forming panmictic populations. Alternative mechanisms such as phenotypic plasticity and a few loci controlled traits provide possible explanations for the sympatric coexistence of discrete nonoverlapping eco-morphotypes with apparent lack of barriers to gene flow within multiple lagoons and drainages.

“…Our diagnostic characteristics for Herichthys follow De la Maza-Beningnos et al (2015) based on their recent revision of the group. Herichthys (before it was divided into Herichthys and Nosferatu) was largely diagnosed by the shared color pattern of bars and/or blotches along the lateral sides of the body, and a breeding coloration consisting of a dark ventral portion and a lighter dorsal portion of the body (Oldfield et al 2015). As recognized here, following De la Maza-Beningnos et al (2015), the traditional breeding coloration characters delineate these clades, but with slight differences in the extent of coloration between Herichthys and Nosferatu.…”

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.

“…Furthermore, separate molecular analysis by Concheiro-Pérez et al (2007), De la Maza-Benignos et al (2015), Hulsey et al (2004), López-Fernández et al (2010), León-Romero et al (2012), Mejía et al (2015), Magalhaes et al (2015), McMahan et al (2015) and Oldfield et al (2015) support the monophyly of the Nosferatu + Herichthys clade as well as separation between both genera. Moreover, the separate analysis of the mitochondrial gene Cox1 by León-Romero et al (2012), De la Maza-Benignos et al (2015), and Mejía et al (2015) reveal the existence of three clades in Nosferatu: 1) the bartoni clade (= phylogenetic group I sensu Mejía et al, 2015); 2) the steindachneri clade (= phylogenetic group II sensu Mejía et al, 2015); and 3) the pantostictus clade (in the study by León-Romero et al (2012) and Mejía et al (2015) some of the lineages of N. pantostictus are misidentified as H. cf.…”

Response paper: Morphometric article by Mejía et al. 2015 alluding genera Herichthys and Nosferatu displays serious inconsistencies

In the present response paper, the article entitled "Morphometric variation of the Herichthys bartoni (Bean, 1892) species group (Teleostei: Cichlidae): How many species comprise H. labridens (Pellegrin, 1903)?" by Mejía et al. 2015 is critically reviewed. The current review pinpoints some of the more conspicuous conceptual inconsistencies and fundamental errors found in the study by Mejía et al. (2015), It is contended that the authors fail to provide any new insights into the complex biogeography and evolutionary history of the Nosferatu and Herichthys genus groups, and that while results of their Cox1 molecular analysis are comparable to those by De la Maza-Benignos et al. (2015), the conclusions of the two studies are not comparable. In addition, it is contested that, whereas the designation of genus Nosferatu by De la MazaBenignos et al. (2015) was found on the principles of the biological and phylogenetic species concepts, the rejection of the genus by Mejía et al. (2015) is solely based "on the presence of (overlapping) morphometric characters" between genera. The assumption by Mejía et al. (2015), that because their geometric morphometrics analysis failed to provide separation of species, then Nosferatu genus does not correspond to a valid taxon; and their suggesting geometric morphometrics "as useful tool to discriminate species, because it allows to propose diagnostic characters" were not supported by their results. While Mejía et al. present some interesting thoughts on the systematics of Nosferatu, they unfortunately fail to provide any data that can be objectively assessed as relevant to motivate any changes in the current taxonomy.El presente documento de respuesta analiza críticamente el artículo titulado "Morphometric variation of the Herichthys bartoni (Bean, 1892) species group (Teleostei: Cichlidae): How many species comprise H. labridens (Pellegrin, 1903)?" por Mejía et al. (2015), así como también evidencia algunas de las contradicciones conceptuales y errores fundamentales encontrados en dicho documento. Se arguye que el artículo no proporciona ningún aspecto nuevo acerca de la compleja biogeografía, ni de la historia evolutiva de los géneros Nosferatu y Herichthys, y que mientras que los resultados del análisis molecular utilizando el gen Cox1 son similares a los de la Maza-Benignos et al. (2015), las conclusiones de ambos estudios no son compatibles. Se contiende además que mientras que la designación del género Nosferatu por De la Maza-Benignos et al. (2015) se fundamentó en principios asociados a los conceptos biológico y filogenético de especie, el rechazo del género por Mejía et al., (2015) únicamente se basa "en la existencia de caracteres morfométricos (superpuestos)" entre géneros. La inferencia por parte de Mejía et al. de que debido a que el análisis de morfometría geométrica no logró separar a las especies, y que por lo tanto el género Nosferatu no corresponde a un taxón válido; así como la observación de que la morfometría geométrica corresponde a "una herramienta útil para di...
