Hi, I’d be grateful if someone could help me with this Terellia observed in a dry coastal meadow in Oslo, Norway, mid June 2025. The pictures I took aren’t great, so there’s a lot of details missing, but I'll give it a shot anyway. Terellia ceratocena and T. plagiata are the only Cerajocera with enlarged male pedicels that are known from Norway and Sweden. As far as I can see, the discal and subbasal bands are too weakly defined for ceratocena, leaving me with plagiata. However, the key I used (Yaran et al., 2018) described a new species in the subgenus: T. akguli, which is similar to plagiata. There are no reported occurrences of akguli in the GBIF database, so I have no idea if it has been found outside of Eastern Türkiye. According to the key, the apical and subapical bands are always separated in plagiata, and fused in akguli. BUT it also states that the subapical and discal bands should be conjoined or fairly close together in akguli, which is not the case here? Are wing pattern characteristics even enough to distinguish the two? The key only covers the Turkish species in the subgenus. Are there any other candidates not included in the key? Or another key I could use instead? I tried (White, 1988) first, which seems to be dated.

1. Do not read junk literature. 2. We are preparing a detailed revision of the sg. Cerajocera, incl. the Middle Eastern species with DNA, right now. 3. As I can see on the picture, the costal cell is hyaline. => plagiata. Both ceratocera and plagiata occur in Northern Europe. (1. Do not read junk literature!)
