摘要

摘要: 该文依据海南吊罗山6号标本描述了树锦蛇属蛇类一新物种——海南尖喙蛇。新种和其大陆姐妹种尖喙蛇的吻端前部都有明显的突起，这与同属的其他5个物种不同。新种与其大陆姐妹种在形态和分子上都存在差异。形态上，新种与尖喙蛇的主要区别是：（1）新种成体无黑眉（vs.有黑眉）；（2）颊鳞2枚（vs.颊鳞1枚）。

Abstract: 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).
