Spinarge miocenicus n. sp., first fossil representative of an extant argine genus, is described from the Upper Miocene lacustrine maar of montagne d’Andance (Coiron Massif, Ardèche, France). The ­extant species of Spinarge Wei, 1998 are distributed from Japan, China, Korea, and eastern Siberia to Europe and live on broad-leaved trees, which are well represented in this paleoflora. During the Late Miocene the area of the Coiron Massif was probably quite favorable for Argidae Konow, 1890 as two of the three described fossil argids also originate from this area and period.
