  author={Stephen J. Walsh and Prosanta Chakrabarty},
  pages={506 - 517}
Caecieleotris morrisi, new genus and species of sleeper (family Eleotridae), is described from a submerged freshwater cave in a karst region of the northern portion of the State of Oaxaca, Mexico, Río Papaloapan drainage, Gulf of Mexico basin. The new species represents the first cave-adapted sleeper known from the Western Hemisphere and is one of only 13 stygobitic gobiiforms known worldwide, with all others limited in distribution to the Indo-Pacific region. The new taxon represents a third… 
A new species of the blind goby Caecogobius (Gobioidei, Gobiidae, Gobionellinae) from a cave system on Mindanao Island, the Philippines
A new species of the eyeless goby genus Caecogobius is described from a cave system on Mindanao Island, the Philippines, which is the second cave-obligate fish ever discovered from the Philippine archipelago.
Freshwater gobies 30 million years ago: New insights into character evolution and phylogenetic relationships of †Pirskeniidae (Gobioidei, Teleostei)
A sister-group relationship of †Pirskeniidae to the Thalasseleotrididae + Gobiidae + Oxudercidae clade and an attempt to relate a fossil gobioid to extant taxa based on phylogenetic analysis are provided.
Genetic and morphological evidence cast doubt on the validity of Mexican troglobitic species of the Neotropical catfish genus Rhamdia (Siluriformes: Heptapteridae)
Investigation of patterns of genetic and phenotypic variation in Mexican troglobitic Rhamdia in a phylogenetic context indicates that external morphology does not allow for unambiguous differential diagnoses and robust distinction among trogLobitic species.
Evolution in caves: selection from darkness causes spinal deformities in teleost fishes
In both species, permanent darkness was associated with significantly higher rates of spinal deformities, which suggests strong developmental constraints on the successful colonization of subterranean environments in teleost fishes and might help explain the relative paucity of cave-adapted lineages.

Background. The Zoque rainforest Chimalapas is located in the Isthmus of Tehuantepec, mainly in the municipalities of San Miguel Chimalapa and Santa Maria Chimalapa in the state of Oaxaca, is
A Review of Fish Taxonomy Conventions and Species Identification Techniques
This review paper attempts to clarify and discuss the latest schools of thought pertaining to fish taxonomy and the techniques for species identification.


Revision of the Endemic Malagasy Cavefish Genus Typhleotris (Teleostei: Gobiiformes: Milyeringidae), with Discussion of its Phylogenetic Placement and Description of a New Species
The new darkly pigmented species, Typhleotris mararybe, is described from an isolated karst sinkhole on the coastal plain below the Mahafaly Plateau, and is unique among blind cavefishes in being uniformly darkly Pigmented, rather than fully depigmented or exceptionally light in coloration.
Tyson belos, new genus and species of Western Pacific fish (Gobiidae, Xenisthminae), with discussions of Gobioid osteology and classification
Tyson belos is described, based on specimens from the Great Barrier Reef, Trobriand Islands, and Lau Islands, a diminutive coral-reef species that appears to be closely related to Xenisthmus Snyder, Allomicrodesmus Schultz, and an undescribed genus.
Status and phylogeny of Milyeringidae (Teleostei: Gobiiformes), withhe description of a new blind cave-fish from Australia, Milyeringa brooksi, n. sp.
A phylogeny of Milyeringidae is reported and a new species is described from Cape Range National Park in the North West Cape (Cape Range Peninsula) of Australia, distinguished on the basis of morphological and molecular characters from its only congener Milyereda veritas.
Thalasseleotrididae, new family of marine gobioid fishes from New Zealand and temperate Australia, with a revised definition of its sister taxon, the Gobiidae (Teleostei: Acanthomorpha)
A contribution to the ongoing clarification of the family Eleotrididae, which has served historically as a repository for genera not classified among the more derived gobioids, is represented.
The Hoosier cavefish, a new and endangered species (Amblyopsidae, Amblyopsis) from the caves of southern Indiana
This is the first new cavefish species described from the United States in 40 years and exemplifies how molecular data can alert us to the presence of otherwise cryptic biodiversity.
Biogeography of subterranean decapods in North and Central America and the Caribbean region (Caridea, Astacidea, Brachyura)

Many, if not the majority, of the troglobites appear to have arisen independently from epigean progenitors rather than sharing common subterranean precursors.
Eleotridae and Butidae are two clades of gobioid fishes, both differing from relatives Gobiidae and Gobionellidae in that they are generally less morphologically simplified, without joined pelvic
