The blood-sucking flies of the genus Geoffroy, 1762 (Diptera: Muscidae) are significant ectoparasites that can cause irritation and transmit pathogens to both animals and humans. Within the genus , two species, and , have similar morphology and coexist in the same habitat. Accurate species identification of these flies is crucial for understanding disease vectors and implementing effective control measures. In this study, we assessed the effectiveness of outline-based geometric morphometrics (GM) by analyzing the wing cell contour of the first posterior cell (R) to distinguish between species and sexes of and . Our results demonstrate that the outline-based GM method is highly effective in distinguishing between species and sexes of these flies based on contour shape, with accuracy scores ranging from 90.0% to 97.5%. Therefore, outline-based GM emerges as a promising alternative to landmark-based GM or as a supplementary tool in conjunction with traditional morphology-based methods for species identification.
1762年杰弗罗伊属（双翅目：蝇科）的吸血蝇是重要的体外寄生虫，可对动物和人类造成刺激并传播病原体。在该属中，两种蝇，即[具体物种1]和[具体物种2]，形态相似且共存于同一栖息地。准确鉴定这些蝇的物种对于了解疾病传播媒介和实施有效的控制措施至关重要。在本研究中，我们通过分析第一后室（R）的翅室轮廓，评估了基于轮廓的几何形态计量学（GM）区分[具体物种1]和[具体物种2]的物种及性别的有效性。我们的结果表明，基于轮廓的GM方法在根据轮廓形状区分这些蝇的物种及性别方面非常有效，准确率在90.0%至97.5%之间。因此，基于轮廓的GM成为基于地标点的GM的一种有前景的替代方法，或者作为与传统形态学方法相结合用于物种鉴定的补充工具。
