INTRODUCTION
Haemagogus capricornii and Hg. janthinomys females are considered morphologically indistinguishable. We analyzed morphometric variability between Brazilian populations of these species using wing geometric morphometry.
METHODS
Size and shape at intra- and interspecific levels were analyzed in 108 Hg. capricornii and Hg. janthinomys females.
RESULTS
Geometric morphometry indicated size and shape variables can differentiate these species at interspecific level. However, at intraspecific level, results show relative differentiation. Two populations of Hg. capricornii had a smaller centroid size with no significant differences between them, whereas all Hg. janthinomys populations showed significant differences.
CONCLUSIONS
Both species were correctly identified by geometric morphometry.
引言
Capricornii 库蠓和 Janthinomys 库蠓的雌性在形态上被认为无法区分。我们使用翅几何形态测量法分析了这些物种巴西种群之间的形态测量变异性。
方法
对 108 只 Capricornii 库蠓和 Janthinomys 库蠓的雌性进行了种内和种间水平的大小和形状分析。
结果
几何形态测量表明，大小和形状变量可以在种间水平上区分这些物种。然而，在种内水平上，结果显示出相对差异。两个 Capricornii 库蠓种群的质心大小较小，它们之间没有显著差异，而所有 Janthinomys 库蠓种群都显示出显著差异。
结论
通过几何形态测量法能够正确识别这两个物种。
