[Aim]  Geometric morphometric analysis was carried out on the wings of seven species of Ptecticus, to provide a new species identification method. [Methods]  Quantitative analysis of seven species of Ptecticus was carried out using the landmarks method. A total of 28 landmarks were selected from each wing photo. Principal component analysis, cluster analysis, and canonical variable analysis was used to explore the morphological variation of the wing veins. [Results]  There were significant differences in the morphology of the wings, primarily located at the ends of subcosta and radial vein. Principal component analysis and cluster analysis showed relatively small differences in wing shape between P. fukienensis, P. vulpianus, and P. srilankai compared with other species. Canonical variable analysis was able to distinguish between the seven species, and the classification effect was optimal. [Conclusion] This article demonstrates the feasibility of applying geometric morphology methods for the classification of Stratiomyidae. Canonical variable analysis of 28 landmarks was able to classify seven species of Ptecticus. The findings of this study establish a foundation for further research into the use of geometric morphometrics for species identification.
