Sarcophaga depressifrons Zetterstedt, 1845: 1293.
Pierretia (Pierretia) obscurata Rohdendorf, 1937: 346. Heteronychia (Spatulapica) kovalae Verves, 1979: 868, syn. nov. Heteronychia compactilobata Wyatt, 1991: 1.
Type material examined. Pierretia (Pierretia) obscurata: Lectotype 3, herewith designated to fix unambiguously the identity of the nominal species and thus promote nomenclatural stability: [blank slip of cardboard] // Dūbova [probably Slovakia] / 17.4.71 [= 1871] // 676 // var. Macr. in / dorso segn. [illegible handwriting] // Sarc. / offuscata / Mg. / Kowarz det. // obscura / ta // 17 / 99 // [red label added by Yu.G. Verves, pers. comm. 2007] 1937 / Hololectotypus / Heteronychia (Spatulapica) / obscurata Rohdendorf // [red label] LECTOTYPE 3 / Pierretia / (s. str.) / obscurata / Rohdendorf, 1937 / des. D. Whitmore 2007 // Sarcophaga / depressifrons / Zetterstedt, 1845 / det. D. Whitmore 2007 (ZIN) and corresponding slide with terminalia: 17 / 99 // [handwritten on slide] Pierretia / (s. str.) / obscurata / Co-Typus / Rohdendorf / 1936 // [red label glued to slide] LECTOTYPE 3 / Pierretia / (s. str.) / obscurata / Rohdendorf, 1937 / des. D. Whitmore 2007 // Sarcophaga / depressifrons / Zetterstedt, 1845 / det. D. Whitmore 2007 (ZIN). Paralectotype: 1 3: Luga, NW Russia, Tolmatschevo, 22.VII.1935, Stackelberg leg. (ZIN).
Remarks. Rohdendorf (1937: 347) based his description of Pierretia obscurata upon an unspecified number of specimens from “Central Europe”, Russia (Leningrad region) and Ukraine. Differently than in most of his other descriptions, he did not explicitly select a holotype for P. obscurata. The above specimen, selected as the lectotype, was the one used by him to illustrate the new species (Rohdendorf 1937: 348, figs 475–476), and its provenance (Dubova – probably Slovakia, possibly Romania) agrees with the generic indication of “Central Europe”.
Heteronychia (Spatulapica) kovalae: Holotype 3: [transliterated from Cyrillic] zhd. st. Timur, Ornb / Tashk, 50 v., Turkst / Klare [illegible symbols] VII.1903 // [red label] Holotypus Heteronychia / (Spatulapica) kovalae / Verves // pinned specimen / Sarcophaga sp. / not subgenus Heteronychia! / det. D. Whitmore 2007 // Genitalia / Sarcophaga / depressifrons / Zetterstedt, 1845 / det. D. Whitmore 2007 (ZIN) [terminalia in a white plastic tube pinned beneath the source specimen].
Remarks. The holotype of Heteronychia kovalae is in fact a mixture of two species: the pinned fly is a Sarcophaga with four postsutural dorsocentral bristles, possibly a Liosarcophaga Enderlein, whereas the terminalia belong to a Heteronychia in accordance with the original taxonomic treatment of the species; this suggests their association with a wrong specimen after dissection of the terminalia. Therefore, the terminalia alone should be considered as representing the holotype.

Remarks. The conspecificity of Pierretia obscurata with Sarcophaga (H.) depressifrons was first recognized by Ringdahl (1945) but was overlooked by subsequent authors until Pape (1986) confirmed the synonymy. Based on the direct comparison of type specimens and on the original illustrations (Verves 1979: 863, fig. 2.6), H. kovalae must also be considered conspecific with S. (H.) depressifrons as treated by Pape (1987), Povolný & Verves (1997) and Richet et al. (in press). Finally, Heteronychia compactilobata was tentatively synonymized with S. (H.) depressifrons by Pape (2004a) (cf. Richet et al. in press). It is also my opinion that the differences outlined by Wyatt (1991: 2–4, figs 1–4) fall within the morphological variability of S. (H.) depressifrons.
