male - 15.5mm - Berlin - June 2017 I am looking through old photos today and i noticed this Asilidae. I cannot match it to anything exactly. I think that Dysmachus trigonus looks similar but i am not sure. I could use some help with this one. If this is not Dysmachus, then a genus will be nice to know. Thank you for your time. johnes81 attached the following image:  [50.88Kb] John and Nini. Naturalists not experts. |

I think you are right with D. trigonus. Although I can't see everything very good the way the wings are held by the creature is also typical for trigonus

Thank you, Reinoud. I will attach another photo here for clarity. I have no experience with Dysmachus - and many other Asilidae genera - so i am hoping that Dysmachus is correct. trigonus is the only Dysmachus recorded for Berlin, so i am able to suggest a species. Germany also has Dysmachus fuscipennis and Dysmachus praemorsus recorded. Maybe this new photo is helpful for verification. I have not examined the specimen. Is there anything in particular that you need to see? Thank you for your time, John johnes81 attached the following image:  [52.04Kb] Edited by johnes81 on 10-07-2018 11:38 John and Nini.

This is D. trigonus. D fuscipennis has strong bristles on the ventral side of femur 1, a longer abdomen and differently shaped genitalia. D. praemorsus and Didysmachus picipes also have different shaped genitalia.

Thank you, Reinoud. I appreciate your time and expertise. I also appreciate the information about D. fuscipennis, D. praemorsus and Didysmachus picipes. I've made a text file with notes. I will try to examine the specimen soon. I've just been very busy lately. I hope that you have a pleasant night
