The graptolite fauna of the Mandalay Region, Myanmar, is poorly known. In this paper, 13 species in the genera Avitograptus, Korenograptus, Metabolograptus, Neodiplograptus and Normalograptus are described from the uppermost Ordovician strata of the area. Two of these species, Korenograptus selectus X. Chen n. sp. and Neodiplograptus mandalayensis X. Chen n. sp., are new. On the basis of the graptolite faunas, a biostratigraphic scheme for the uppermost Ordovician (Hirnantian: Metabolograptus extraordinarius Biozone and Metabolograptus? persculptus Biozone?) strata in this area is erected.

缅甸曼德勒地区的笔石动物区系鲜为人知。在本文中，13种在属Avitograptus，Korenograptus，Metabolograptus，Neodiplograptus和Normalograptus从区域的最上奥陶纪地层说明。这些物种中的两个，Korenograptus selectus X. Chen n。sp。以及曼德勒的Neodiplograpraptus X. Chen。sp。，是新的。在笔石动物群的基础上，对生物地层方案最上面的奥陶纪（赫南特：Metabolograptus extraordinarius生物带和Metabolograptus？persculptus 在该区域竖立了生物区？）地层。
