The type species Hongshanopterus lacustris was in 2008 named and described by Wang Xiaolin, Diogenes de Almeida Campos, Zhou Zhonghe and Alexander Wilhelm Armin Kellner. The generic name combines a reference to the Hongshan culture in Lioaning with a Latinised Greek pteron, "wing". The specific name means "of the lake" in Latin, referring to the lake deposits the fossil was found in, at Dapinfang.[1]
Hongshanopterus is based on the holotype IVPP V14582, found in a layer of the Jiufotang Formation dating from the Aptian, It consists of a skull and five neck vertebrae of a single subadult individual.[1]
The wingspan of Hongshanopterus was estimated at 1.8 to 1.9 meters. It possessed a relatively high number of teeth, about thirty-six for both upper jaws combined. The teeth were robust and had triangular crowns which were flattened from mouth side to "lip" side, like those of other istiodactylids. The pterygoid bone had a ridge at the underside, pointing obliquely to the front and the outside.[1]
