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.
