South-East African Burrowing Grasshopper (Acrotylus mossambicus)
The South-East African Burrowing Grasshopper was described in 1893, it apparently is widely distributed over parts of Mozambique, South Africa, Tanzania and Zimbabwe.
The species has apparently not been recorded since 1946 and might be extinct, however, given its wide distribution this assumption seems quite strange.

Trimenia malagrida ssp. malagrida (Wallengren)
Scarce Mountain Copper (Trimenia malagrida ssp. malagrida)
The Scarce Mountain Copper is a little butterfly species with at least four subspecies that occur in some regions of South Africa; the nominate form from the Cape Peninsula is thought to be extinct.
The last known population that was known to exist in the late 1980s inhabited an extremely small area and counted only some 20 to 50 individuals; they apparently disappeared due to forest fires that occurred too often and got out of control.
The photo below shows an individual from another subspecies, the Cederberg Scarce Mountain Copper (Trimenia malagrida ssp. cedrusmontana (Dickson & Stephen)).

Erica velitaris Salisb.
Armed Heath (Erica velitaris)
The Armed Heath is one of numerous heath species that are endemic to the Western Cape Province of South Africa, its taxonomic status is not fully clearified and it may in fact be a hybrid, however, there are two additional varieties that sometimes are accepted, Erica velitaris var. hemisphaerica Bolus, and Erica velitaris var. parvibracteata Bolus.
If this is in fact a true species with three subspecies, then the nominate may be extinct.

Hippotragus leucophaeus (Pallas)
Bluebuck (Hippotragus leucophaeus)
The Bluebuck was described in 1766; during the Late Pleistocene, the species was very widespread in South Africa, but the populations began to shrink following climatical changes at the beginning of the Holocene, in historical times, the species was finally restricted to a relict population that inhabited a rather small region at the southern tip of South Africa.
The species had a generally bluish gray fur, the upper lip and a patch in front of the eye were somewhat lighter, the forehead was brown, the belly was whitish.
The Bluebuck was hunted to extinction by European settlers, it is actually the first African mammal to become extinct in historical times, the last individuals were killed in 1799 or 1800.

Erepsia promontorii L. Bolus
Cape Erepsia (Erepsia promontorii)
The little Cape Erepsia was known to occur at three areas on the cape Peninsula, South Africa; one was Cape Point, a cliff at the southern end of the Cape Peninsula, the other two were at the town of Hermanus and at Sea Point, today a densely populated suburban of Cape Town.
The species was last seen in 1950 and is believed to be possibly extinct, howevere, it was found growing in the so-called Hangklip Sand Fynbos, a habitat that still exists at least at Cape Point, thus there is still some hope that this species might be rediscovered some day.

Willdenowia affinis Pillans
Table Mountain Willdenowia (Willdenowia affinis)
This species is known from the type material only which was collected in 1918 from the northern slopes of the Table Mountain near Cape Town in the Western Cape province of South Africa.
The area in which this plant was found is now overgrown by alien plants and the species was never found since the collection of the type and is thus most likely extinct. [1]

Baur’s Xysmalobium was described in 1907, it is known from a single collection that was made in 1890 where today is the city of Bizana in the Eastern Cape Province of South Africa.
The former habitat of the species is now transformed for subsistence agriculture or is severely overgrazed or otherwise destroyed, it was never relocated since its description and is therefore considered extinct.

The slit-leaved Alepidea is only known from the type material that was collected in 1910 at Gaika’s Kop, a 1963 m high, isolated elevation in the Amathole Mountains in the South African Eastern Cape Province.
Various searches for the species have failed and it must be considered likely extinct.

Pyramid Heath (Erica pyramidalis)
The Pyramid Heath was restricted to what today is the city of Cape Town in the Western Cape Province, South Africa.
The species disappeared at the beginning of the 20th century due to the destruction of its habitat by the expanding city, and, despite the fact that the species was even cultivated for some time it is now considered extinct. [1]

Lepidochrysops methymna ssp. dicksoni Tite
Dickson’s Dark Opal (Lepidochrysops methymna ssp. dicksoni)
The Monkey Blue is widely distributed in the Eastern- and Western Cape Provinces of South Africa, the species has very high demands concerning the structure of its habitat.
The caterpillars in the first few days of their life feed on two plant species, Pseudoselago serrata (P. J. Bergius) Hilliard and Pseudoselago spuria (L.) Hilliard, hereafter they require the presence of colonies of a special ant species, Liengme’s Camponotus Ant (Camponotus liengmei For.) (or Camponotus maculatus ssp. liengmei For.), in whose anthills they live from the third instar on as brood parasites, feeding on the eggs and larvae of the ants.
***
Dickson’s Monkey Blue, called Tygerberg-bloutjie in Afrikaans, was described in the year 1964. The subspecies was restricted to a very tiny area of only about 4 km² on the northwestern side of the Tygerberg range – this area was converted into agricultural land for wheat farming, whereby both, the food plants as well as the ant colonies were destroyed.
Dickson’s Monkey Blue is now considered extinct.

Holothrix culveri Bolus
Culver‘s Holothrix (Holothrix culveri)
Culver’s Holothrix, described in 1905, is a very inconspicuous orchid species that is known exclusively from the type collection, originating from 1890.
The type locality is located close to what today is the town of Barberton in the Mpumalanga Province of South Africa, and is now completely destroyed by a road that was built right across the site, the habitat is heavily degraded due to spread of informal settlements.
Thus, the species is considered most likely extinct. However, search operations undertaken repeatedly between 2002 and 2006 produced the finding of at least one plant that may be this species, yet there is only this single plant, and its identity has obviously not been confirmed ever since.

Leucadendron grandiflorum (Salisb.) R. Br.
Wynberg Conebush (Leucadendron grandiflorum)
The Wynberg Conebush obviously was described on the basis of a drawing, made from a plant grown in Great Britain, to where it was imported as a garden plant around 1809.
The only information about the species we have today is that it originated from a place called Wynberg, which today is a southern suburb of the city of Cape Town in Western Cape, South Africa.
The Wynberg Conebush disappeared around about 1800, when its habitat was destroyed due to urbanization. [1]
