Het grijs gitje Cheilosia griseiventris sensu Stubbs & Falk (1983) in Nederland (Diptera: Syrphidae).

Cheilosia griseiventris sensu Stubbs & Falk (1983) new to the Netherlands (Diptera: Syrphidae) Although already recognized as a distinct species in Britain by Stubbs & Falk (1983), other authors have treated Cheilosia griseiventris (Zetterstedt, 1843) as a (possible) synonym of C. latifrons Loew, 1857. Unpublished taxonomic results indicate that these taxa should be considered as separate species, but also that there may be more than two European species involved. So possibly the name griseiventris is not applied correctly. However, until the taxonomy of the latifrons-complex is fully resolved, we use the name griseiventris. The nine specimens from the Netherlands agree with the British specimens of C. griseiventris. Based on these specimens, the species is recorded from the Netherlands for the first time. All specimens were collected in August and September. The localities suggest a preference for open, ruderal, possibly calcareous areas.
