Notes on the taxonomy of species of Sciomyzini with a predominantly setulose anepisternum. Nikita E. Vikhrev and William L. Murphy. Notes on the taxonomy of species of Sciomyzini with a predominantly setulose anepisternum (Diptera, Sciomyzidae)

The present paper was conceived originally as a straightforward, simple description of a new African taxon. It grew substantially as more research was conducted. It now consists of four parts. In Part I we discuss the taxonomy of five taxa of Sciomyzini with a predominantly setulose anepisternum: Atrichomelina pubera, Ditaeniella grisescens, D. trivittata, Pherbellia pilosa, and Ph. shatalkini. In Parts II and III we consider the three taxa initially included in the genus Ditaeniella sensu Rozkosn'y (1987) (D. grisescens, D. parallela, and D. patagonensis) and the taxon described herein, D. milleri sp. nov., analysing this group by use of both the classical morphological approach (Part II) as well as by analysis of molecular data from available DNA barcodes (Part III). In Part IV we provide a key to the taxa of Sciomyzini worldwide that have a predominantly setulose anepisternum. We also provide a list of specimens examined, the data from which significantly supplement the information previously available regarding the distribution of several Palaearctic species.
