Crossocheilus klatti


Taxonomy [top]

Kingdom Phylum Class Order Family

Scientific Name: Crossocheilus klatti
Species Authority: (Kosswig, 1950)
Common Name(s):
English Anatolian Golden Barb
Tylognathus klatti Kosswig, 1950
Taxonomic Notes: This poorly known species has been placed in many genera since its description. Recent placement in the South East Asian genus Crossocheilus is a lapsus. Indeed, the (unpublished) rediscovery of the species allowed to demonstrate, that the species belong to the genus Garra and is closely related to Garra kemali, which is still placed in the genus Hemigrammocapoeta. All species in Hemigrammocapoeta belong to the genus Garra.

This species is known from Lake Işıklı basin in the Büyük Menderes drainage, Turkey. It seems to be absent from the lake itself but occurs in two separate in-flowing spring systems: Işıklı spring, and in a stream near Dinar. It also occurs in spring-fed streams (30 km of stream) around Bagili in upper Küpu drainage. Populations in Egirdir and Gölcük lakes are extirpated. The species is mostly impacted by water abstraction for various reasons. It has an estimated extent of occurrence (EOO) of 1,800 km², and an area of occupancy (AOO) of 160 km², and it is known from three locations (based on water abstraction). Therefore it is assessed as Endangered.

Population [top]

Population: Two of the four subpopulations are considered to be extirpated. While it cannot be excluded that more populations exist, all are believed to be at least slightly declining due to many threats in the area.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: Inhabits densely vegetated shores of streams, springs and lakes.
Systems: Freshwater

Use and Trade [top]

Use and Trade: This species is not directly used by humans.

Threats [top]

Major Threat(s): Water abstraction, pollution and climate change are the most important threats affecting this species. But alien species where the drivers of the extirpation of the two extirpated populations. Therefore the species might be quite vulnerable to alien species impacts.

Conservation Actions: None known to be in place.
