Buzzatii 果蝇物种簇由兄弟物种 D.uzzatii、D.koepferae、D.serido、D.borborema、D.seriema、D.antonietae 和 D.gouveai 组成，所有这些果蝇都专门在腐烂的仙人掌组织中繁殖，除了 D.buzzatii（一种定殖的次世界性物种）外，都是南美洲特有的。使用形态测量方法和 17 个翅膀参数的多变量分析，我们研究了该簇的兄弟物种之间翅膀形态的差异程度。物种之间存在显着差异，判别分析表明，翅膀形态有足够的差异，可以对所分析的 70 个个体中的 98.6% 进行正确分类。基于马哈拉诺比斯距离平方 (D-2) 的 UPGMA 聚类分析推断出的物种之间的表型关系总体上与之前发表的系统发育关系一致。这些结果表明 D.uzzatii 簇内的翅膀形态具有系统发育的重要性。
The Drosophila buzzatii species cluster consists of the sibling species D. buzzatii, D. koepferae, D. serido, D. borborema, D. seriema, D. antonietae and D. gouveai, all of which breed exclusively in decaying cactus tissue and, except for D. buzzatii (a colonizing subcosmopolitan species), are endemic to South America. Using a morphometric approach and multivariate analysis of 17 wing parameters, we investigated the degree of divergence in wing morphology among the sibling species of this cluster. Significant differences were obtained among the species and discriminant analysis showed that wing morphology was sufficiently different to allow the correct classification of 98.6% of the 70 individuals analysed. The phenetic relationships among the species inferred from UPGMA cluster analysis based on squared Mahalanobis distances (D-2) were generally compatible with previously published phylogenetic relationships. These results suggest that wing morphology within D. buzzatii cluster is of phylogenetic importance.
