摘要
选取分布于中国境内的 8属 9种灵猫科动物的 88个骨骼性状、 31个外部形态性状和 1个行为性状 ,运用替代外群法分别以赤狐 (犬科狐属 )和青鼬 (鼬科貂属 )共同或单独作为外群进行支序分析 ,得出 10个支序图 ,其步长 (TL)为 10 6～ 136 ,一致性指数 (CI)为 0 5 81～ 0 6 6 0 ,保留指数 (RI)为 0 6 10～ 0 714。经合意分析得到 4个相似的支序图 ,其TL为 4 1～ 136 ,CI为 0 5 81～ 0 732 ,RI为 0 6 10～ 0 818,结果支持 :①斑灵狸、大灵猫、小灵猫构成一个单系群 ,与传统分类一致 (均属灵猫亚科 ) ;②椰子狸、花面狸、熊狸构成一个单系群 ,与传统分类一致 (均属长尾狸亚科 ) ;③红颊、食蟹与灵猫科其他种为姐妹群关系 (Bootstrap检验支持率 10 0 % ) ,建议类为一亚科 ;④长颌带狸拥有较多自近裔性状如三个门齿孔 ,是一个高度特化的种类 ,其系统地位有待进一步研究。
A total of 88 variable osteological characters,31 external characters and 1 behavior character were found among the nine species of family Viverridae in China which belong to eight genus respectively.Ten cladograms were generated with tree lengths (TL) 106-136,consistency indices (CI) 0.581-0.660 and retention indices (RI) 0.610-0.714 using outgroup substitution method when the species Vulpes vulpes and Martes flavigula were combined as the outgroup or either of them as the sole outgroup alternatively.After using consensus techniques,we obtained four similar cladograms which were TL 41-136,CI 0.581-0.732 and RI 0.610-0.818.Evidendce is presented to support the following hypotheses:①Prionodon pardicolor,Viverra zibetha and Veverricula indica form a monophyletic group.It's consistent with the traditinal taxonomy arrangement in which the three species belong to Viverrinae.②Paradoxurus hermaphroditus,Paguma larvata and Arctictis binturong form a monophyletic group.It's consistent with the traditinal taxonomy arrangement in which the three species belong to Paradoxurinae.③The clade of Herpestes javanicus and H.urva is the sister group of other species of Viverridae in China.The bootstrap tests support this outcome by 100%.Our result suggest that the mongoose should be arrange as a subfamily Herpestinae.④Chrotogale owstoni is a highly specialized species owing to having several peculiar character status such as three incisive foramen.Its taxonomic position would be resolved as more species of the family Viverridae are included in future studies.
