During the investigation of biodiversity of diatoms from Great Xing’an Moutains,more than six hundreds samples were collected and studied.Totally,10 taxa from Naviculaceae were newly recorded in China which belong to four genera.They are:Frustulia crassinervia (Brébisson) Lange-Bertalot & Krammer;Neidium ampliatum (Ehrenberg) Krammer,Neidium apiculatum Reimer,Neidium binodeformis Krammer;Navicula upsaliensis (Grunow) Peragallo;Stauroneis amphicephala Kützing,Stauroneis fluminopsis Van de Vijver & Lange-Bertalot,Stauroneis gracilior Reichardt,Stauroneis leguminiformis Lange-Bertalot & Krammer,Stauroneis mediterranea Lange-Bertalot & Van de Vijver.The detail descriptions of the taxonomical and ecological features of each species are given in this paper.
