In this paper we present four new species of Sapindopsis from northeastern Asia which extend our understanding about the geographical and stratigraphic ranges of the genus and also its morphology. Sapindopsis orientalis sp. nov. and Sapindopsis sp. 1 from the Frentsevka Formation, Partizansk Basin, Primorye, Russia are the earliest (lower Albian) occurrences of the genus Sapindopsis. Sapindopsis asiatica (G. Philippova) Golovneva et Zolina comb. nov. from the upper Albian-lower Turonian Krivorechenskaya Formation, Anadyr River Basin, Chukotka, Russia constitute the northernmost species (paleolatitude 740 N). Sapindopsis chinensis sp. nov. from the upper Albian Dalazi Formation, Jilin Province, China and upper Albian Alchan Formation, Alchan Basin, Primorye, Russia is distinguished from other species by alternate arrangement of the leaflets. Analysis of morphological diversity in Sapindopsis provides new information about evolutionary trends of early Platanaceae during mid-Cretaceous.
