Calopteryx atrocyana (Fraser, 1935)
Taxonomic Notes: This species was transferred by Wilson and Xu (2007) to the genus Atrocalopteryx.

Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2011
Date Assessed: 2010-11-27
Assessor(s): Phan, Q.
Reviewer(s): Wilson, K.D.P., Dow, R.A., Hämäläinen, M., Reels, G., Manh, C.D., Choong, C., Zhang, H., Tong, X., Yu, X. & Brooks, E.

This species has been extirpated from its type locality, and its presence in Viet Nam is severely threatened by logging activities. It is known from four other sites in southern and southwest China, where it has a very localised distribution. The Chinese populations currently have no known threats, and it may be more widely spread than is currently known, so pending further information it is assessed as Near Threatened (close to meeting VU under D2).

Geographic Range [top]

Range Description:This species is known from Viet Nam (Dong Mo, Chi Lang district (where the habitat has been lost) and Huu Lien Nature Reserve in Lang Son province) and from southern China (Guizhou and central and north Guangdong provinces).
Countries occurrence:
China (Guangdong, Guizhou); Viet Nam
Additional data:
Number of Locations:5
Upper elevation limit (metres):250

Population [top]

Population:It has a very localised distribution, but can be common where it occurs. It may currently be under-recorded as it is similar to Matrona basilaris, a very common and widespread species.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:

A large sized beautiful damselfly of brilliant metallic green. It is found  in  primary or old secondary forests, at the base of hills and mountains, and is known also to breed in open aspect streams in the vicinity of forest.

Systems:Terrestrial; Freshwater

Use and Trade [top]

Use and Trade: No information available

Threats [top]

Major Threat(s):

The type locality of this species has been destroyed by deforestation. Agricultural pollution is very widespread in Viet Nam, and in Huu Lien Natural Reserve, the forest is being destroyed for wood exploitation. No threats are known in Guangdong.

Conservation Actions [top]

Conservation Actions: More research is needed on this species' distribution, habitat and potential threats. This species would benefit from site protection in the remaining distribution in Viet Nam.
