Abstract

The revision of the sarcophagid species Lepidodexia (Orosarcophaga) ornata (Townsend, 1927) reveals its identity and a generic synonym. The male terminalia of this species was studied in detail for the first time and revealed its congeneric affinities with Oxyvinia Dodge, 1966. Consequently, the generic status of Orosarcophaga Townsend, 1927 was revalidated, including Oxyvinia Dodge, 1966 as its junior synonym, and O. ornata was corroborated as a valid species and name. Moreover, we provide an updated generic diagnosis of Orosarcophaga, a list of the eleven species of the genus with their distribution, and a detailed diagnosis of O. ornata.

Highlights

The genus Lepidodexia sensu Pape (1996) is composed of 32 subgenera, of which 11 are monotypic (e.g., Orosarcophaga), and it is recognized mainly by some features present in the male terminalia (Pape, 1996; Buenaventura & Pape, 2018)
After a detailed morphological study of Orosarcophaga ornata, it is clear to state that this species shares diagnostic features with members of the genus Oxyvinia Dodge, 1966, as those elucidated by Dodge (1966), Lopes (1982), Pape (1996), and Buenaventura & Pape (2018)
O. ornata does not resemble any other species currently allocated in Oxyvinia, and it is corroborated as a valid species as well

Summary

Introduction

The genus Lepidodexia sensu Pape (1996) is composed of 32 subgenera, of which 11 are monotypic (e.g., Orosarcophaga), and it is recognized mainly by some features present in the male terminalia (Pape, 1996; Buenaventura & Pape, 2018). The species currently recognized as Lepidodexia (Orosarcophaga) ornata (Townsend, 1927) was originally described in the monotypic genus Orosarcophaga Townsend, 1927. Later, this genus was considered a junior synonym of Lepidodexia by Pape (1996), who gave a subgeneric status to Orosarcophaga, keeping only its type species. Pape (1996) did not explain his criteria for this taxonomic arrangement but stressed that no action was taken to correct the homonymy between
