Abstract

We describe a new species of reed snake of the genus Calamaria Boie 1827, from Mindoro Island, Philippines. The new species differs from all other species of Calamaria by having the following combination of characters: a high number of subcaudal scale pairs (> 40 in males, > 30 females) and ventrals + subcaudals (> 205 in males, > 210 in females); mental scale not contacting chin shields; dorsal surface of head, body, and tail uniformly dark brown; and ventral surface of body (extending to include part or all of first longitudinal row of dorsals) uniformly pale (yellow or white in life). The new species is likely most closely related to Calamaria schlegeli Duméril, Bibron, and Duméril 1854, which also has a high number of subcaudal scales compared to other Calamaria species. The new species is the second Calamaria species known from Mindoro Island and the eighth known from the Philippines, and its presumed distant relationship from other Philippine Calamaria suggests an additional colonization of the Philippines by this genus from continental Asia.

标题菲律宾民都洛岛菖蒲属芦苇蛇一新种(菖蒲科:菖蒲科)

我们描述了一种新的芦苇蛇属Calamaria Boie 1827，来自菲律宾民都罗岛。该新物种与Calamaria的所有其他物种不同，具有以下特征组合：大量的囊下鳞片对（雄性>40，雌性>30）和腹鳍+囊下鳞片（雄性>205，雌性>210）；心理量表不接触下巴护盾；头部、身体和尾部的背面均匀地为深棕色；身体的腹面（延伸到包括第一纵向背排的部分或全部）均匀地苍白（生活中为黄色或白色）。该新物种可能与Calamaria schlegeli Duméril、Bibron和Dumériel 1854亲缘关系最为密切，与其他Calamaria物种相比，后者也有大量的囊下鳞片。该新种是民都罗岛已知的第二个Calamaria物种，也是菲律宾已知的第八个物种，其与其他菲律宾Calamaria的亲缘关系推测表明该属从亚洲大陆对菲律宾进行了额外的殖民化。关键词：生物多样性、生物地理学、Calamaria-alcalai新种、蛇、角鲨、系统学
