Genus name

The genus had been once named as Secutor but Secutor was coined by Gistel in 1848 with Forsskål’s Scombrops equula as its type species, this being a synonym for Leiognathus equulus . In 1904 Fowler created the genus Deveximentum with Bloch’s Zeus insidiator as its type species. Catalog of Fishes states that as the type species for Secutor is synonymous with L. equulus then Secutor is a synonym of Leiognathus and prefers Fowler’s Deveximentum. [1]

Species

There are currently eight recognized species in this genus: [2]

It grows to 10 cm (3.9 in) TL.

<i>Leiognathus longispinis</i> Species of fish

Leiognathus longispinis, commonly known as the longspine- or Smithurst's ponyfish, is a fish of brackish and marine waters found in the Indian and western Pacific Oceans, from India through Malaysia and Indonesia south to northern Australia and east to the Philippines and Fiji It was described in 1835 by French Zoologist Achille Valenciennes from a specimen caught off Waigeo island in Irian Jaya in New Guinea. In 1886 Ramsay and Ogilby described what turned out to the same species from Hood Lagoon in Papua New Guinea, naming it Leiognathus smithursti. In 2008, ichthyologists Prosanta Chakrabarty and John S. Sparks resurrected the genus Aurigequula and placed L. longispinis and L. fasciatus in it, on the basis of a horizontal row of yellow markings on their flanks and elongated second spine of the dorsal fin. However, a molecular study showed that the genus Leiognathus was nested within Aurigequula, and hence the genera were merged once more. Fishbase places this species in Leiognathus while retaining the striped ponyfish in the monotypic Aurigequula.

<i>Deveximentum insidiator</i> Species of fish

Deveximentum insidiator or previously Secutor insidiator, the pugnose ponyfish or barred ponyfish, is a species of ray-finned fish, a ponyfish in the family Leiognathidae. The barred ponyfish's mineralized skeleton contains apatite and the mineralized tissue contains hydroxylapatite. They have bare heads with nuchal spines and their bodies are a distinctive, reflective silver, frequently imitated by fishermen using silver lures. They have a protracted mouth pointing upward and the tip of the maxilla reaches well below the level of the lower margin of the eye. Barred ponyfish feed on zooplankton, including larval fishes and crustaceans. Body depth is twice or slightly more than standard length, which measures 11.3 cm from the tip of the snout to last vertebra. The lateral line ends before the dorsal fin.
