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." "

Notabene:

• This is a treatment for species recorded from Southern Africa only. Distribution data is for Southern Africa only, most species listed here do occur beyond the subregion.
• iNat calls the genus Craspedophorus "Yellow-spotted" Ground Beetles which is very apt for some species, less so or misleading for other species. Some species have patches or fascia rather than spots, some are unicolor without maculae. Some species have yellow patches, others have orange-reddish patches.
• The best known and perhaps most common species is Craspedophorus bonvouloirii, but it is hardly identified to species level on iNat, the iNat community seems to be not brave enough to make a call and determine a species or some users are overenthusiastic and Id them all as C. bonvouloirii not being aware that there are numerous similar species known from the region. This species was given the common name "Yellow-spotted Ground Beetle" in several editions of Picker et al. Field Guide to insects of South Africa, which is an okayish name, as the beetle has four yellow large patches, but this is true for the entire complex of the*erichsoni* and nobilis groups. The shape of the spots is however distinctive for several groups or species: roundish, subquadrate, transverse, fascia-like, serrated, rounded or straight edge of the patches, small to large.
• Distinguishing characters are: shape of pronotum, pronotum pedunculate or not, shape and size of elytral markings, colour of elytral markings, lack of elytral markings.
• Identification: All listed species are illustrated in the five Häckel papers. Carefully compare to the photos and known distribution and make a call. I am optimistic that we can determine most of the observations to species level provided the photos show enough detail.

Niger, pedibus ruffs, corpore supra et subtus dense flavo-cinereo-pubeseenti, singuli elytri maculis tribus (aliaque communi media) magnis subcircularibus denudatis, maculis posticis duabus conjunctis, apicalibus, majoribus, medio cinereo-pupillatis; corpore oblongo-ovali, valde convexo.
Long. 3.5-4.5 mm. ; lat. 2-2.5 mm.

This very distinctively marked species is entirely covered with greyish-yellow hair, with the exception of seven nearly round areas upon the elytra, which are quite black, bare or clothed with much finer pubescence than the rest of the upper surface. One of these patches is placed at the middle of the elytral suture and the others are arranged in a circle round it, one behind the scutellum on each side, one at the outer margin and one occupying the sutural angle, the last larger than the rest and having a central spot of grey pubescence.
It is a convex insect of elongate-oval shape. The club of the antenna is three-jointed and short, the terminal joint not longer than it is broad.
