  "description": "<p>The taxonomic identification of fly species through wing geometry is a helpful tool for entomologists and<br>\nofficials involved in forensic research, who not necessarily require expertise on insect taxonomy.<br>\nMembers of the Muscidae family are relevant sources of evidence in forensic entomology; however,<br>\ndeveloping countries often lack experts in the taxonomical identification of essential species for the<br>\nassessment of aspects such as the minimum postmortem interval (mPMI). Our study proposes a low-cost,<br>\nfast, and technologically-accessible quantitative tool for the identification of Atherigona orientalis and<br>\nOphyra aenescens, associated with human corpses at advanced states of decomposition. We propose a tool<br>\nthat is based on the geometric variability observed in eight homologous landmarks on wing veins and the<br>\ninterpretation of morphometric estimates after a generalized Procrustes analysis. The use of a geometric<br>\napproach for effective discrimination between Atherigona orientalis and Ophyra aenescens was supported<br>\nby statistically significant differences in wing conformation and size. The evidence presented in this study<br>\nshows that the analysis of geometric variability in the wing morphology of species of forensic relevance<br>\ncan contribute to simple and objective species identification. Geometric morphometrics is a simple and<br>\nreadily available tool for forensic science.</p>",
