Endophytus anemones ( Hering, 1924)

Pelmatopus anemones Hering, 1924: 238–240 . Holotype ♀ (GBIF-GISHym2806; images: https://doi.org/10.6084/

m9.figshare.7880252) in ZMHB, examined. Type locality: Berlin, Finkenkrug ( Germany). Endophytus anemones: Hering 1934: 353 . Neopelmatopus anemones: Conde 1934: 181 . Pelmatopus tenuiserra Lindqvist, 1949: 66 . Holotype ♀ (http://id.luomus.fi/GL.7592) in FMNH, examined. Type locality: Kar-

jalohja ( Finland). Synonymy with anemones by Vikberg (1967). Pseudodineura tenuiserra: Hellén 1960: 6 . Pseudodineura anemones: Verzhutskii 1981: 151–152 .

Additional description. Body length: ♀ 3.0–4.0mm [♂ unknown]. Entirely black, except for pale labrum, palps, more or less clypeus, tibiae, more or less tarsi, and apical parts of femora. Wing venation anomalies, such as the presence or absence of fore wing veins 2r-rs and 2m-cu (Fig. 11), are particularly common in E. anemones (see Vikberg 1967 for more details). The structure of the frontal area also varies significantly ( Vikberg 1967). Lancet: Fig. 33.

Total number of specimens examined: 18♀.

Similar species. The very narrow valvulae 3 in dorsal view, rough upper mesepisternum, and usually nearly closed basal part of the fore wing anal cell are all characters which readily distinguish E. anemones from the European Pseudodineura species.

Life history. Host plants: Anemone nemorosa ( Hering 1924, Altenhofer & Pschorn-Walcher 2006), and Anemone ranunculoides ( Hering 1935) in Europe; according to Verzhutskii (1981) Anemone reflexa in Siberia.

Distribution. Central and northern Europe, north to southern Finland ( Vikberg 1967), eastern Siberia ( Verzhutskii 1981). Occurrence in Sweden: Skåne ( Benander 1966), Västmanland, Ångermanland (own records: mines).
