Sarcophaga subgenus Sarcorohdendorfia Sarcorohdendorfia Baranov, 1938a: 173. Type species by monotypy: Sarcorohdendorfia adiscalis Baranov, 1938a [= Notochaeta indusa Curran, 1936]. Tricholioproctia Baranov, 1938b: 414. Type species by original designation: Sarcophaga antilope Böttcher, 1913 [teste Pape (1996: 396)]. Hamimembrana Chen, 1975: 115. Type species by original designation: Sarcophaga basalis Walker, 1859 [teste Pape (1996: 396)]. Shinonagaella Verves, 1997: 48. Type species by original designation: Pierretia urceola Shinonaga & Beaver, 1979 [teste Pape & Whitmore (2022: 71)]. Lehisca Kurahashi & Tan, 2012: 308. Type species by original designation: Lehisca cameroni Kurahashi & Tan, 2012 [= Pierretia urceola Shinonaga & Beaver, 1979] [teste Pape & Whitmore (2022: 71)]. Omarisca Kurahashi, Tan & Leh, 2021: 132. Type species by original designation: Sarcophaga longifilia Salem, 1946. Syn. nov. Johnsonimyia: Lopes & Kano (1979: 659). Incorrect subsequent spelling of Johnstonimyia Lopes, 1959. Diagnosis: Members of the genus Sarcophaga (sensu lato) [diagnosis in Pape (1996); Buenaventura & Pape (2017)] with 4–6 dorsocentral setae of which at least the anterior two are rather short; proanepisternum setose; anatergite with well-developed setae along ventral margin directed more or less ventrally (Fig. 6); terminalia black or dark brown to reddish; harpes short, never forming an arm-like process; juxta well developed and arching anteriorly; vesica often apically with a pair of recurving or hook-shaped processes, never shaped like medially apposed plates; lateral stylus well developed, slender, often elongated [stoutly enlarged in S. vanuatu Pape and S. hugoi Pape]. Remarks: This circumscription of the taxon Sarcorohdendorfia will include Sarcophaga longifilia Salem and thereby imply a synonymy with the monotypic genus Omarisca Kurahashi, Tan & Leh, 2021, syn. nov., of which S. longifilia is the type species. Lopes & Kano (1979) provided a conspectus of Sarcorohdendorfia with a key to species recognized by them as belonging to this taxon plus their possible close relatives. They studied the female holotype of the nominal species Phalacrodiscus whitneyi Curran, and although they noted the similarity with S. imitatrix (Baranov), they considered P. whitneyi not to be conspecific with the latter because “females of imitatrix show broad transverse marks on second abdominal tergite” (Lopes & Kano 1979: 658). However, based on the material available for the present study (see below), we consider Chrysosarcophaga imitatrix Baranov, 1938 to be a senior synonym of Phalacrodiscus whitneyi Curran, 1936, syn. nov. Both have Guadalcanal Island as their type locality, and species-specific features in the abdominal colour pattern and the distribution of pale and dark setae on gena and postgena provide an exact match.
