Scientific Name:

Gomphus davidi

Species Authority:

Selys, 1887

Common Name/s:

English

–

Levant Clubtail

Taxonomic Notes:

This east Mediterranean endemic is morphologically well distinct from other regional Gomphus species. The syntype series came from Iskenderun, Beirut and Damascus (Selys 1887). St. Quentin's (1965) record from Izmir (= Smyrna) is certainly a misidentification of G. schneiderii and therefore correctly not listed by Kalkman and van Pelt (2006); the same holds true for the specimens reported by St. Quentin (1994, 1995) and by Asahina (1973) from northern Iraq. Most likely both refer to Gomphus kinzelbachi (Schneider, 1984).

Red List Category & Criteria:

Least Concern ver 3.1

Justification:
Gomphus davidi has a range of less than 100,000 km², but there have been regular records all over its range for the last seven decades (see species' bibliography for details). Gravel extraction may cause problems for the species in the future at some localities. However, it is assessed as Least Concern at present.

Geographic Range [top]

Range Description:	Although Gomphus davidi has a very restricted range, confined to Turkey (around Gulf of Iskenderun), Syria, Lebanon, Israel, Jordan and Palestine, the number of localities and number of records suggests that it is locally common.
Countries:	Native: Israel; Jordan; Lebanon; Palestinian Territory, Occupied; Syrian Arab Republic; Turkey (Turkey-in-Asia)

Population [top]

Population:	No exact data on population structure and size are available for this species. But the frequency of records (especially in the northern Jordan Valley and along the Orontes) suggest that the population is stable.
Population Trend:	Stable

Habitat and Ecology [top]

Habitat and Ecology:	Frequents slow flowing rivers and also nearly stagnant irrigation canals/ditches. The flight period starts as early as March (Schmidt 1938, Schneider 1984b), but most data are from April/May. There are records for Turkey until August (Dumont 1977). The larva was described by Schneider (1984b).
Systems:	Terrestrial; Freshwater

Threats [top]

Major Threat(s):	No major threats are known for this species at global level. In Turkey, mining may be a threat to populations there.
