Pipiza carbonaria Meigen, 1822 ( fig. 1–6)

Anikina, 1971: 21 [Zakarpatska Region], 1973: 17

[Carpathians].

Literature data. Ukraine, Zakarpatska Region , Marmarosh (= Marmarosky ) Ridge, Dilove vil., 15.07.1964, 1 ♂ (Z. Anikina) (not located) .

Material examined. Ukraine, Odesa Reg., Budei env., 48.04337N 29.231838E, edge of oak ravine forest, waterlogged meadow, 15.05.2010, on flowers of Ranunculus sp. , 1 ♂ (G. Popov) .

Distribution. Austria,? France, Serbia, Switzerland, Ukraine ( Anikina, 1971; Maibach et al., 1992; Vujić et al.,

2013; Speight et al., 2018; Vujić et al., 2018; Milić et al., 2019; Speight, 2020; Wakkie, 2021).

Diagnosis. Very variable species with characteristic styli ( Vujić et al., 2013). By external morphological features, male of Pipiza carbonaria is similar with several species of the genus with black postpedicel (basoflagellomere) and apical tarsal segments black. From Pipiza austriaca Meigen, 1822 , P. carbonaria easily separated by hind femur without distinct bulge on ventral apical third (in P. austriaca , hind femur with distinct bulge on ventral apical third). From Pipiza fasciata Meigen, 1822 , especially from the dark forms (without yellow spots on tergites), P. carbonaria (at least our specimen) can be distinguished by: mesopleura, sides of abdomen and hind femur and tibia predominantly with pale pile (in dark forms of P. fasciata , these parts of the body predominantly with black pile); the distance from the anterior ocellus to the posterior ocellus looks little different from the distance between the posterior ocelli (in P. fasciata , the distance from the anterior ocellus to the posterior ocellus is distinctly greater than the distance between the posterior ocelli). Pipiza carbonaria differs from P. noctiluca (Linnaeus, 1758) and P. notata Meigen, 1822 by the tergites 1–2 with predominantly with pale pile (in other species, tergites 1–2 predominantly with black pile).

Pipiza carbonaria is most similar to Pipiza lugubris (Fabricius, 1775) in having lateral sides of tergites 1–2 predominantly with pale pile, hind femora thickened, but without bulge on apical third. Pipiza carbonaria can be separated from P. lugubris by the almost hyaline wing (in P. lugubris , wing with quite distinct dark area in the middle

part); shortened and truncated postpedicel as on fig. 4 (in P. lugubris , postpedicel usually distinctly longer). Nothing is said about the darkening of the wing of P. carbonaria , and about possible variations of this character. Wings of our specimen with very faint darkening.

Pipiza carbonaria clearly differs from all the species by elongated surstylus ( fig. 3). This character is unique among European Pipiza . At the same time, it is difficult to reliably distinguish this species by external morphological character, especially considering their significant variability. It can be distinctly identified only based on male genitalia ( Vujić et al., 2013).
