Profundulus balsanus was described by Ahl in 1935 and later placed in synonymy with P. punctatus. Recent molecular studies have demonstrated that specimens identified as P. balsanus belong to a distinct taxon. Herein we used a combination of morphometric, meristic, coloration and osteological data in order to demonstrate the distinctiveness of P. balsanus. Additionally, we used molecular data to reconstruct a phylogeny to place P. balsanus in a systematic context. Profundulus balsanus belongs… Expand
Two new species of Gyrodactylus von Nordmann, 1832 from Profundulus oaxacae (Pisces: Profundulidae) from Oaxaca, Mexico, studied by morphology and molecular analyses.
Maximum likelihood and Bayesian inference analyses indicated that the two new species are members of independent, well-supported lineages - these are the first Gyrodactylus species described from Profundulus oaxacae. Expand
Description of a New Species of Killifish of the Genus Profundulus (Atherinomorpha: Profundulidae) from the Mexican State of Oaxaca
The discovery and description of this new species from the Mexican state of Oaxaca, raises the number of species from this region to five and suggests that this area has been an important center for diversification within this lineage of killifishes. Expand
Spinitectus mixtecoensis sp. nov. (Nematoda: Cystidicolidae), from the Oaxaca killifish Profundulus punctatus (Osteichthyes: Profundulidae) from Mexico, with comments on the distribution of Spinitectus humbertoi in the genera Profundulus and Tlaloc
Maximum likelihood and Bayesian inference analyses indicated that this new species forms an independent, well-supported clade with high posterior probability, and is the third species of Spinitectus recorded in profundulid fish from Central America. Expand
Phylogenetic relationships and ecological niche conservatism in killifish (Profundulidae) in Mesoamerica.
It is suggested that niche divergence is a driving evolutionary force that caused the diversification and speciation processes of the Profundulidae, along with the geological and climatic events that promoted the expansion or contraction of suitable environments. Expand
Profundulus chimalapensis, una nueva especie de pez ciprinodóntido (Cyprinodontiformes: Profundulidae) del Río Coatzacoalcos, México
Profundulus chimalapensis, a new species of cyprinodontid fish (Cyrpinodontiformes: Profundulidae) from the Coatzacoalcos River, Mexico. Introduction: The genus Profundulus is considered aExpand
Effect of conservation of fish in formalin and ethanol on length‐weight relationships and condition factor in Tlaloc labialis (Günther, 1866)
Summary The effect of the preserver on the length-weight relationship and condition factor were estimated using 50 specimens of Tlaloc labialis; a small stream fish from the Grijalva River basin,Expand


A new species of Profundulus (Cyprinodontiformes: Profundulidae) from the Honduran central highlands.
A new species ofProfundulus, Profundulus portillorum, from the Honduran central highlands is described, which has a more slender body, smaller eye, fewer anal rays, caudal rays and lateral-line scales than other species. Expand
Profundulus kreiseri, a new species of Profundulidae (Teleostei, Cyprinodontiformes) from northwestern Honduras
Profundulus kreiseri and Profundulus portillorum are the only two species ofprofundulus that are endemic to the region south of the Motagua River drainage in southern Guatemala and northwestern Honduras. Expand
Profundulus hildebrandi, A New Cyprinodontid Fish from Chiapas, Mexico
One of the genus Profundulus, which is characteristic inhabitants of the mountain streams of Middle America, is described as new to science, one of the most distinctive of which is described below asnew to science. Expand
Phylogenetic relationships and evolutionary history of the Mesoamerican endemic freshwater fish family Profundulidae (Cyprinodontiformes: Actinopterygii).
This study investigated the phylogenetic relationships and evolutionary history of the eight recognized extant species of Profundulidae using three mitochondrial and one nuclear gene markers and proposed a conservative taxonomic hypothesis with five species within Profundulus and three within Tlaloc. Expand
Genetic variation and taxonomic analysis of the subgenus Profundulus
The previously postulated old Central American origin of Profundulus is supported by the data, and the mountain uplift that gave rise to the current division of Pacific and Atlantic rivers may be the reason for the current distribution pattern of the subgenusProfundulus. Expand
Evolutionary history of the genus Rhamdia (Teleostei: Pimelodidae) in Central America.
The mtDNA data indicate that Rhamdia most likely colonized Central America in the late Miocene or Pliocene, promoting a strong role for the Isthmus of Panamá in the Mesoamerican expansion of this genus. Expand
Freshwater Fishes of Mexico
Though Mexico is only one-fifth the size of the continental United States, it is home to nearly two-thirds as many freshwater fishes as those that swim the waters of the United States and CanadaExpand
MEGA6: Molecular Evolutionary Genetics Analysis version 6.0.
An advanced version of the Molecular Evolutionary Genetics Analysis software, which currently contains facilities for building sequence alignments, inferring phylogenetic histories, and conducting molecular evolutionary analysis, is released, which enables the inference of timetrees, as it implements the RelTime method for estimating divergence times for all branching points in a phylogeny.
