Meloe (Meloe) hottentotus Péringuey 1885

Diagnostic description by @beetledude

Meloe (Meloe) hottentotus -- Eastern ZA Oil Beetle
Six or seven species, belonging to two subgenera, of Meloe oil beetles occur in southern Africa. The genus is unmistakeable: fairly large, black beetles, some of them with a greenish, bluish, purplish sheen, sometimes metallic; all flightless, with shortened elytra; and mostly with a hugely distended abdomen.

Three Meloe species are known from KwaZulu-Natal and from the Eastern Cape, two species of the subgenus Afromeloe and the third in the subgenus Meloe. The subgenus Meloe is easily told apart from the Afromeloe therein that the middle antennal segments (Nos 5, 6, 7) are modified, but unmodified in Afromeloe. In the males [this observation] those segments are crooked and enlarged; in females those segments are broader than the other segments.

The single species of subgenus Meloe known from this area is Meloe (Meloe) hottentotus. This species can be distinguished from other southern African Meloe by the following combination of characters:
• Middle antennale segments modified [as above].
• Head and pronotum with coarse, deep and dense punctures.
• Pronotum elongate, longer than wide.
• Punctures on head and pronotum dense but distinctly separated from each other.
• Distribution ECape, KZN, Free State, Lesotho, Mpumalanga.

Tranlsated from Latin:
Cyan, shiny, antennae long, joints 5-7 thickened in male, compressed; prothorax elongate, deeply punctate; elytra aciculate [=marked with fine irregular streaks like needle scratches].

Length 13-22mm, width 4-7 mm.
The head is deeply punctured and separated from the epistome by a longitudinal impression; the antennae are long reaching as far as the middle of the elytra; in the male the 5 and 7 article are enlarged and compressed, the 6, the largest of the three is hollowed; the palpi are black and slightly infuscated at the tips.
The prothorax is deeply punctured, slightly convex on the upper side, attenuated near the base the margin of which is slightly sinuated; above the basal margin is a slight depression, and the outer sides are perpendicular.
The elytra are broader than the prothorax and three times as long. They diverge greatly from the middle and are finely aciculated.
The abdomen and underside are finely punctured.
The legs are coppery dark-blue, the tarsi are very slightly hirtose underneath.
From Port Elizabeth, Cape Colony, and Leydenberg, Transvaal.

Pérenguey 1909, page 170 explains the common name of the genus Meloe: "When seized they exude through the joints of the legs, especially the knees, a yellow fluid, much in the same manner as in the genus Horia. It is this peculiarity which has gained for them the popular name of " oil beetles." "

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.’

Pierfilippo Cerretti
Associate Professor of Zoology
Dipartimento di Biologia e Biotecnologie 'Charles Darwin'
Sapienza Università di Roma

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:
https://forgottenbooks.com/fr/readbook/RevueZoologiqueAfricaine_10400543#46
and a pretty good match except for the scutellum which is not all black.
Unfortunately the original description of Succingulum exiguum not available:
