我们进行了几何形态测量分析，调查的形态变化的金狼，犬lupaster，并澄清形态和分类的亲缘关系的不同类群的属犬和Lupulella。我们认为，在复杂的犬lupaster内观察到的变化可能是不兼容的预期为一个单一的物种。我们假设，名义形式C。L. soudanicus是Lupulella adusta的同义词，而不是金狼复合体的一部分。亚种C. L. BEA具有广义的豺狼形态（即，与L. mesomelas和C. aureus）和C. L.黄腹叶蜂在形态空间上处于中间位置，介于豺狼型和型之间。这些结果与先前发表的分子分析形成对比，其中线粒体数据未能确定金狼种群之间的差异，核证据表明存在与形态学分析恢复的群体不相容的群体。关于其他胡狼，我们的研究结果描绘了L。M. mesomelas和L. M. schmidti和L. adusta。我们呼吁注意需要更综合的方法来解决各种非洲犬科的分类问题。
We conducted a geometric morphometric analysis to investigate the morphological variation of the golden wolf, Canis lupaster, and to clarify the morphological and taxonomic affinities of different taxa of the genera Canis and Lupulella. We suggest that the variation observed within the complex of Canis lupaster may be incompatible with what would be expected for a single species. We hypothesize that the nominal form C. l. soudanicus is a synonym of Lupulella adusta rather than being part of the golden wolf complex. The subspecies C. l. bea has a generalized jackal morphology (i.e., clusters together with L. mesomelas and C. aureus) and C. l. lupaster occupies an intermediate morphospace position, between jackal-like forms and wolf-like forms. These results contrast with previously published molecular analysis in which mitochondrial data failed to identify differences among golden wolf populations, and nuclear evidence points to the existence of groups that are incompatible with those recovered by morphological analysis. Regarding other jackals, our results depict the absence of morphological overlap between L. m. mesomelas and L. m. schmidti and no differences between putative subspecies of L. adusta. We call attention to the need for more integrative approaches to solve the taxonomic questions in various African Canidae.
