Chrysosoma nellyae (Diptera: Dolichopodidae), a New Fly Species Discovered from Bohol Island, Philippines

Abstract

A new fly species, Chrysosoma nellyae, has been recently discovered in Bohol, Philippines. Aside from the metallic blue head with black antennae which are reminiscent of Chrysosoma species, its thorax is metallic blue with a greenish and brown prescutellar patch, scutellum brown, blue green border with hair like bristle. In addition, based on the similarity of the male genitalia, cercus morphology, and legs, the new species appears to be related to C. crinicorne. To increase the accuracy of species identification, DNA barcoding of the mitochondrial cytochrome oxidase I gene was employed and further inferred for its phylogenetic relationship with other Chrysosoma species.
