Trogonospila exigua (Villeneuve 1935)
Trogonospila exigua
I was encouraged by Traian Bertau to contact the professor, Pierfilippo Cerretti, regarding the ID of this beautiful tachinid fly. His response is as follows:
‘The images you sent clearly show Trogonospila. Although any identification to species level from a photo is questionable, it is compatible with T. exigua as you suggested.’

More info from Traian Bertau:
Probably Trigonospila exigua which was considered a synonym of Trigonospila mista and has been revived in 2016 https://zookeys.pensoft.net/article/6072/element/4/4102//
Succingulum exiguum Villeneuve, 1935 was treated as a synonym of Trigonospila mista (Villeneuve, 1913) by Crosskey (1980b: 858) but is recognized here as a distinct species based on examination of the holotype by PC.
(O'Hara. 2016. Annotated catalogue of the Tachinidae)
The description of Trigonospila mista is available here:

and a pretty good match except for the scutellum which is not all black.
Unfortunately the original description of Succingulum exiguum not available:
Villeneuve, 1935a: 142. Villeneuve J (1935a) Myodaires supérieurs africains inédits. Revue de Zoologie et de Botanique Africaines 27: 136–143
Holotype male (IRSNB). Type locality: South Africa.
