Identification of Megaselia (Diptera: Phoridae) species using wing vein landmarking
<p>A semi-automated identification system using wing venation is described for the large, taxonomically challenging genus <i>Megaselia</i> Rondani (Diptera: Phoridae). Wing photographs make two-dimensional images that can be landmarked and analyzed to produce transformed (standardized) x-y coordinates, and are well-suited for a semi-automated approach. We landmarked wing photographs of individuals of 108 specimens of <i>Megaselia</i> from the ZADBI (Zurqui All Diptera Biodiversity Inventory) project, as well as 284 specimens of <i>Megaselia</i> from the Los Angeles based BioSCAN (Biodiversity Science: City and Nature) project and ran them against libraries of one specimen of each species of the fauna from each site, respectively. Accuracy was about 52-67% for the first identification, with 86-95% of correct identifications in the top 5 candidates list. Expanding the library to include all identified specimens raised the likelihood that the first identification was correct to 93-96% of specimens, with 97-98% correct identifications in the top 5 list. Incorporating major body color (dark brown versus yellowish) to the identification system increased accuracy to 100% for the ZADBI specimens; other, easily-seen characters were used for problematic LA specimens. We suggest that a wing photograph be included in all <i>Megaselia</i> species descriptions to allow this semiautomation of identification based on morphology, and further that this system could provide a bridge to DNA-based species descriptions from old holotypes in collections.</p>
