Abstract A new species of ponyfish in the genus Photoplagios is described from material collected in coastal waters of northeastern Madagascar. Photoplagios antongil, new species, is distinguished from congeners by the presence of a broad midlateral stripe and two darkly pigmented flank patches located ventral to the lateral midline, which are presumably translucent in life but darkly pigmented in preservative due to a concentration of melanophores. The new species is further distinguished from… 
Description of a new genus of ponyfishes (Teleostei: Leiognathidae), with a review of the current generic-level composition of the family.
TLDR
Photolateralis, new genus, is unique among ponyfishes in possessing a translucent mid-lateral flank stripe, which depending on the species, may be either a composite "stripe" comprised of numerous independent translucent windows, or a continuous translucent lateral stripe.
Description of a New Species of Ponyfish (Teleostei: Leiognathidae: Equulitini: Photolateralis) from the Gulf of Oman
TLDR
A new species belonging to the leiognathid genus Photolateralis, collected from the coastal waters of Oman, is described herein and is characterized by a lower jaw that is deep and convex in lateral view.
Geometric morphometrics uncovers a new species of ponyfish (Teleostei: Leiognathidae: Equulites), with comments on the taxonomic status of Equula berbis Valenciennes
TLDR
A new species of Equulites is revealed using geometric morphometric techniques and is herein described, and the taxonomic status of Equula berbis Valenciennes is reviewed and is concluded to be a nomen dubium of uncertain placement beyond the family level.
The new genus Eoleiognathus for the percoid fish Pygaeus dorsalis Agassiz from the Eocene of Bolca in northern Italy, a putative ponyfish (Perciformes, Leoignathidae)
The new genus Eoleiognathus of putative leiognathid fish (Perciformes, Percoidei) is established for Pygaeus dorsalis Agassiz, 1838 from the Eocene locality of Bolca in northern Italy. This genus
A New Species of Ponyfish (Teleostei: Leiognathidae: Photoplagios) from the Philippines
TLDR
Both sexes of the new species of ponyfish can be distinguished from congeners by body shape, pigmentation pattern on the upper flank, and length of the second dorsal-fin spine.
Taxonomic revision of the Equulites elongatus (Günther 1874) species group (Perciformes: Leiognathidae) with the description of a new species
Taxonomic analysis of a group of morphologically similar and phylogenetically related ponyfishes (Perciformes: Leiognathidae) establishes the Equulites elongatus species group comprising three valid
Evolution of the light organ system in ponyfishes (Teleostei: Leiognathidae)
TLDR
Both internal and external sexual dimorphism in the ponyfish LOs were recovered as most likely to have evolved in the common ancestor of Leiognathidae, and likelihood‐based correlation analyses indicate that the evolution ofinternal and external dimorphisms in males is statistically correlated.
MOLECULAR PHYLOGENY OF LEIOGNATHIDAE IN THE WATERS OF PERHENTIAN ISLANDS, TRENGGANU, MALAYSIA
TLDR
16S mitochondrial rRNA gene sequences were used to infer the phylogenetic relationships among nine morphospecies of leiognathids and showed that 16S mitochondria rDNA is a good marker for phylogenetic analysis of the Leiognathidae.
Rediscription of Ponyfishes ( Teleostei: Leiognathidae) of Sri Lanka and the Status of Aurigequula Fowler 1918
TLDR
The ponyfishes of Sri Lanka are redescribed from recent collections and Aurigequula Fowler, 1918 is resurrected from synonymy with Leiognathus Lacepede, 1802 to replace a previously established invalid name.

A Clade of Non-Sexually Dimorphic Ponyfishes (Teleostei: Perciformes: Leiognathidae): Phylogeny, Taxonomy, and Description of a New Species
TLDR
It is shown that the evolution of the leiognathid LOS can be traced from a “simple” non-sexually dimorphic circumesophageal light organ to a complex and species-specific luminescence system involving not only major structural modifications of the light organ itself but also numerous associated tissues.
Leiognathus elongatus (Perciformes: Leiognathidae): Two Distinct Species Based on Morphological and Light Organ Characters
TLDR
The use of the light-organ system is proposed in clarifying questions of leiognathid taxonomy by recognizing two species: L. stercorarius Evermann and Seale (group I), a previously buried synonym of L. elongatus (Glinther) (group II), which includes fishes previously named Equula elongata Giinther and L. popei (Whitley).
Evolution and diversification of a sexually dimorphic luminescent system in ponyfishes (Teleostei: Leiognathidae), including diagnoses for two new genera
TLDR
It is hypothesized that the species‐specific, sexually dimorphic internal and external modifications of the leiognathid LOS provide compelling evidence for an assortative mating scheme in which males use species‐ specific patterns of lateral luminescence signaling to attract mates, and that this system functions to maintain reproductive isolation in these turbid coastal environments.
A systematic review of the fishes of the family Leiognathidae
TLDR
The revision collates earlier literature, supplementing with original data based on examination of fresh material of 18 species of the three genera, Leiognathus Lacepfede, Secutor Gistel and Gazza Ruppell from the seas around India and re-examination of types of some species.
External and internal sexual dimorphism in leiognathid fishes: Morphological evidence for sex‐specific bioluminescent signaling
TLDR
A bioluminescent signaling function by males is suggested for the sexual dimorphism in leiognathids, which may play an important role in the schooling behavior as well as in species and sexual recognition of these coastal fishes.
Revision of the Australian species of the fish family Leiognathidae
TLDR
The Australian species of Leiognathidae are revised and their distinguishing features more clearly defined and incorrect usage in the literature of several species names, including L. brevirostris and L. lineolatus, is discussed.

The fishes constitute the next class found in our carboniferous strata. Two groups only are represented—Plagiostomous fishes, such as the sharks and rays; and Lepidoganoids, or fishes with enamelled
Three new modes of luminescence in the leiognathid fish Gazza minuta: Discrete projected luminescence, ventral body flash, and buccal luminescence
Three new modes of luminescence are described for Gazza minuta (Bloch) (Perciformes: Leiognathidae) as observed in specimens collected in the Philippines in April and May, 1982: discrete projected
PHYSIOLOGICAL AND MORPHOLOGICAL STATE OF THE SYMBIOTIC BACTERIA FROM LIGHT ORGANS OF PONYFISH.
TLDR
A maximalluminescence, minimal-growth bacterial model of this symbiosis is led to.
ENDOSYMBIOTIC BIOLUMINESCENT BACTERIA FROM THE LIGHT ORGAN OF PONY FISH
TLDR
The isolated symbiotic bacteria were compared with free living bacteria isolated directly from sea water in the same area where the fish were collected, and it was possible to estimate the total number of viable bacteria within an organ, and to compare this with the weight of the organ.
