Hi, To discriminate between the females of Ectophasia crassipennis and E. oblonga, the bending of sternite 7 is crucial: E. crassipennis - sternite 7 bent forwards, E. oblonga - sternite 7 bent backwards a little at the end. Both species were present, and photographing this character is tricky; however, I tend to E. crassipennis concerning this female (seen in southern Brandenburg on 03.10.2015). What do you say? Thanks for opinions, Sundew Sundew attached the following image:  [230.21Kb] |

You are very silent ! Meanwhile I found out from the papers by Blaschke et al. (2018; https://resjourna...syen.12272) and Euo & Han (2021; https://www.resea...tic_status) that the bent, shovel-like piercer is actually sternite 8. Fig. 2K in Blaschke et al. as well as Steven Falk`s photos of female terminalia in E. crassipennis (https://www.flick...2511503368) are a good match. Unfortunately I did not find pictures of E. oblonga for comparison, just the sketch Fig. 227 in Tschorsnig & Herting (https://tachinida...igures.pdf). So is there anyone (Theo?) who can contribute to the discussion? Otherwise I would publish this female as E. crassipennis. |
