Leptobarbus

Siamese barb ( Leptobarbus hoevenii )

Leptobarbus ( Gr. " leptos " = thin Lat: . " Barbus " = Bartel ) is a Southeast Asian carp fish species.

Features

Leptobarbus species are 8.5 cm to one meter long. Their scales are medium in size. The mouth does not reach the anterior margin of the orbit. Around the mouth there are four barbels. The gill rakers are short, lanceolate and are widely spaced. Dental formula for the pharyngeal teeth: 5.3.2-2.3.5. The dorsal fin originates above the pelvic fins approach and is supported by an undivided and divided seven soft rays, the anal fin short of five split soft rays. The lateral line runs down and is located on the caudal peduncle on the bottom half. A dark side strips to the juvenile fish disappears with age.

Species

Fishbase lists five types:

  • Siamese barb ( Leptobarbus hoevenii ( Bleeker, 1851) )
  • Leptobarbus hosii ( Regan, 1906)
  • Leptobarbus melanopterus MCW Weber & de Beaufort, 1916
  • Leptobarbus melanotaenia Boulenger, 1894
  • Leptobarbus rubripinna ( Fowler, 1937)

System

The genus Leptobarbus was described in 1860 by the Dutch ichthyologist Pieter Bleeker and put into the monotypic subfamily Leptobarbinae 1864. Their isolated position within the carp has retained the genus to date. She is the sister group of a clade of tench ( Tincinae ), cardinal fish ( Tanichthys ) bitterlings ( Acheilognathinae ) Gründlingsverwandten ( Gobioninae ), white fish ( Leuciscinae ) and the East Asian Oxygastrinae.
