Ba Be National Park is a great place for Gomphidae and not all are found as roadkill. This interesting gomphid was found along a tiny stream bordering some otherwise not very interesting rice paddies near one of the villages in the reserve. For a fine description of the nomenclature in relation to A. xanthenatus, see also the blog entry on this species in Vietodonata.
