Colophon montisatris

Assessor: Riaan Stals

Sensitive in 2010
Reason for the sensitivity status
Wild specimens of this species and genus are known to be targeted and collected for trade. Trade in dead and alive stag beetles causes population decline. This species has a vulnerable population size with risk of the whole extant population being harvested. Recovery may not be possible. Releasing data on this species can exacerbate threat and vulnerability.
This species is extremely rare in the wild and is known to be exploited, utilised or traded. The localities of remaining populations need to be protected to avoid any further exploitation, which is likely to drive it to extinction.
Exploitation extent
Significant - wild individuals of the species are known to be exploited, collected, traded or utilized in a targeted manner, and utilisation is widespread, affects the majority of wild populations and/or is causing rapid decline of the wild population.

2. Prior, existing or proposed conservation status


2.1. Published IUCN Red List Status (1996)

Critically Endangered B1+2e (ver. 2.3).

Annotation: Needs updating.

REFERENCE: Bellamy & Endrödy-Younga (1996h).


2.2. IUCN Red List Status revised 2011 (unpublished)

Red List Status: Critically Endangered: CR B1ab(v)+2ab(v).


  • Known from only a single location.

  • EOO < 1 km² and AOO < 1 km².

  • Under ongoing collection pressure to supply the beetle collector's trade.

  • Potentially threatened by future climate change due to it being restricted to one moist high-altitude mountain peak.

Comment on the 2011 Red List evaluation:

In February 2018 I was informed of the existence of a treasure-trove of unpublished locality, temporal and ecobiological data that resulted from a wide-ranging field survey of all Colophon species, carried out approximately from 2007 to 2014. It seems that the custodians of this information have decided against the publication thereof. I immediately launched an attempt to hopefully obtain those data for the next round of Red List evaluations of all the known and valid species of Colophon.

From what I have been told in confidence, it seems that this hitherto unutilised information has the potential to alter the Red List status of some of the Colophon species.

3. Exploitation extent

Specimens of any and all Lucanidae (stag beetles) have for many decades been probably the most sought-after beetles among armchair and safari collectors in affluent communities. A simple Google search will reveal the enormous extent of international trade in stag beetles, both as dead, preserved specimens and as livestock. Two enduring trends in the trade of beetles are the following:

  1. Rare, scarce and other difficult-to-obtain beetle species are more valuable than commoner species or species that are easier to obtain, and rare and scarce beetle species command higher prices.
  2. Larger individual specimens within any collectable beetle species are more valuable than smaller specimens and command higher prices.

Among stag beetles worldwide, the species of Colophon (Cape Mountain Stag Beetles) are only of moderate size. They are, however, widely considered as among the rarest of all stag beetles, or even as the rarest of all stag beetle species in the world. They are frequently marketed and advertised as such. Colophon specimens are said to be particularly prized among beetle collectors.

All the species of the genus Colophon are endemic to the Western Cape Province of South Africa. Twenty-one species are presently known and considered valid. Wealthy armchair and safari collectors of beetles have a general aim to own a "complete" collection, meaning representative specimens of all the species and subspecies within a focal taxonomic group, in this case the genus Colophon.

For perhaps more than a century and a half already, "gentleman collectors" have been advised of what species are potentially available for them to obtain through catalogues, more often than not published by purveyors of deadstock. This practice reached its pinnacle with the luxurious and exceptionally expensive books published since 1999 by Taita Publishers in the Czech Republic. The Taita books clearly serve both as appetisers for the wealthy beetle collector and as modern shopping catalogues, brilliantly designed and illustrated, representing the gamut of what an armchair collector would like to obtain for his collection in order for it to become "complete". For the Lucanidae (stag beetles) of Africa, Taita published in 2004 a truly magnificent book (Bartolozzi & Werner 2004), wherein the 16 species and non-nominotypical subspecies of the genus Colophon known at the time were "advertised" with large and magnificent photographs.


Evidence for trade in Colophon species

This genus is popular in trade and there is demand from international markets for the collection of rare and endemic Colophon species as indicated by media news reports and several online marketplace, e-commerce, and auction sites. In 2004, arrests were made for the poaching and possession of endangered Colophon species, a genus known to be valuable to international collectors (Planet Ark, 2004; Pretoria News, 2004; Sunday Times, 2004). The above assessments suggests that the genus is being targeted and that this species is at risk. See attached files for further trade evidence.

Population vulnerability
Population is vulnerable: size is <= 2500 mature individuals OR the number of known subpopulations is <= 5 OR range is <= 100km2 OR species at risk of localised extinctions
Justification and references


The population of Colophon montisatris is vulnerable for the following reasons:

  1. Known from only a single (sub-)population.
  2. EOO < 1 km² and AOO < 1 km².
  3. Potentially at risk of localised extinction, and known from only a single location.
  • The population size is unknown.

Targeted demographics
Mature (breeding) individuals are killed, significantly weakened or are permanently removed from the wild, OR immature individuals are targeted and this significantly impacts mature (breeding) individuals.
Justification and references

The trade in dead, preserved beetles necessarily permanently removes mature (adult) individuals from the wild. Please see above for examples and discussion.

Regeneration potential
This species has a slow population growth rate, or the growth rate varies depending on habitat, and there is a poor chance the wild populations will recover from exploitation OR a collector might feasibly harvest the entire extant population removing the chance of subsequent recruitment.
Justification and references

◘ No information exists about the regeneration potential of this species.

◘ It is not unthinkable that a collector may harvest the entire extant population, or such a large proportion thereof, that it may not recover. Only a single population with EOO < 1 km² and AOO < 1 km² is known. With current knowledge, recruitment from elsewhere is hence impossible.

As this species has a vulnerable population and is at risk of localized extinction, it is highly susceptible to rapid decline through collection. Recovery may be poor.
