|Scientific Name:||Rhinagrion hainanense|
|Species Authority:||Wilson & Reels, 2001|
Rhinagrion yokoii Sasamoto, 2003
|Taxonomic Notes:||Rhinagrion yokoii Sasamoto, 2003 is a junior synonym of this species (Kalkman and Villanueva 2011).|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Reviewer/s:||Dow, R.A. & Allen, D.|
The species has a wide distribution occurring in southwest China, Lao PDR and Viet Nam (Wilson and Reels 2001, Sasamoto 2003, Kalkman and Villanueva 2011). It seems generally to be uncommon and is expected to show a decline as its habitat, forest streams, are under pressure. It does however not match any of the criteria and the species is therefore assessed as Least Concern. The species was assessed as Vulnerable in 2009, but present information suggest more records are available showing that it has a far more extensive range.
|Range Description:||Wilson and Reels (2001) described the species from a single male collected from Lumu, Hainan in June 1999.
The species is currently known from China (Hainan (Fan Jia and Jiaxin, both in eastern Hainan; Graham Reels, unpub. data) and Guizhou Province), Lao PDR (as R. yokoii from Sekong in southeastern Lao PDR) and Viet Nam (Dak Lak Province, Thua Thien Hue Province and Khanh Hoa Province) (Kalkman and Villanueva 2011).
