Taxonomy [top]

Kingdom	Phylum	Class	Order	Family
ANIMALIA	ARTHROPODA	INSECTA	ODONATA	CALOPTERYGIDAE

Scientific Name:	Matrona basilaris
Species Authority:	(Selys, 1853)
Infra-specific Taxa Assessed:	See Matrona basilaris ssp. japonica
Taxonomic Notes:	Two forms previously treated as subspecies or synonyms of M. basilaris are currently recognised as distinct species: M. nigripectus (Sélys, 1879) and M. kricheldorffi (Karsch, 1891); however there is not universal agreement that these should be treated as distinct species, although they are treated as such here. A subspecies M. b. japonica (Förster, 1897) occurs in Japan.

Assessment Information [top]

Red List Category & Criteria:	Least Concern ver 3.1
Year Published:	2009
Date Assessed:	2007-06-29
Assessor/s:	Dow, R.A.
Reviewer/s:	Kalkman, V. & Clausnitzer, V. (Odonata Red List Authority)
Justification: Matrona basilaris is widespread in China and north Viet Nam at least, capable of surviving in secondary forest habitats and well represented in protected areas. For this global assessment Least Concern status is justified for the species.

Geographic Range [top]

Range Description:	As currently recognised Matrona basilaris basilaris occurs at least in north Viet Nam and China (Hämäläinen 2004), where there are records from Inner Mongolia, Shanxi, Henan, Anhui, Zhejiang, Fujian, Shaanxi, Sichuan, Jiangxi, Guandong, Guangxi, Hainan and Yunnan. The exact distribution of the species is not entirely clear due to taxonomic problems. M. b. japonica occurs in the Ryukyu Islands.
Countries:	Native: China (Anhui, Fujian, Guangxi, Hainan, Henan, Jiangxi, Nei Mongol, Shaanxi, Shanxi, Sichuan, Yunnan, Zhejiang); Japan; Viet Nam

Conservation Actions [top]

Conservation Actions:	There is a need for further distributional data, and for the resolution of taxonomic issues. Beyond this M. basilaris does not appear to need specific conservation measures across most of its range, apart from monitoring of populations to check for any decline.
