摘　　要：A new species of the genus Gonyosoma Wagler,1828 is described herein based on six specimens from the Diaoluoshan Mountains,Hainan Island,Hainan Province,China.The new species,Gonyosoma hainanense sp.nov.,is most similar to its continental sister species,Gonyosoma boulengeri(Mocquard,1897).Both taxa have a scaled protrusion on the anterior portion of the rostrum,distinct from other congeners.However,Gonyosoma hainanense sp.nov.can be distinguished from G.boulengeri by two significant morphological characters:(1)black orbital stripe absent in adults(vs.present in G.boulengeri);and(2)two loreals(vs.one loreal in G.boulengeri).The new species is also genetically divergent and forms a unique clade from its sister species and all other congeners based on sequences of the mitochondrial gene cytochrome b(cyt b).
