I have found this female Oxycera at Urup Dam on Funen in Denmark (21. Juli 2016). Using the key in Stubbs & Drake i end up with Oxycera fallenii. A species that is considered extinct in Denmark. But i am not sure. For example i vory about the large dots on tergite 3. They seems more rounded and bigger then i have seen on illustrations. One of the key characters should be silvery hairs/dusting behind the eyes. I can se this character very clearly. Is that significant? Any help?

Hej Kabalm, I think that your specimen is belonging to Oxycera rare. Females of this species might sometimes have a small pair of lateral spots on tergum 2. This character is unfortunately not taken into account in keys. I observed such females and it is noted as well in literature by Rozkosny (Rozkošný, R., 1983, A Biosystematic Study of The European Stratiomyidae (Diptera). Vol.2. Clitellariinae, Hermetiinae, Pachygasterinae and Bibliography. Series Entomologica, 25. Dr.W. Junk, The Hague, pp. 1–431.: page 151). Regards Piet |

Hej Piet Ok, that makes sense! I have read the descriptions of the two species but never seen this mentioned. O. rara is rare but widespread in the area and seems more likely. In addition everything seems to fit with O. rara, even the more rounded dots on tergite 3. I will keep the collected specimen save for documentation and call it O. rara, thanks to your helpfull remarks! Regards Ken |
