Corallus ruschenbergerii

[Jo-Jo]

Hallo zusammen!

Wie lauten die deutschen Namen von Corallus ruschenbergerii und Corallus hortulanus cookii, die bei meiner letztjährigen Trinidad-Reise in den Caroni Swamps beobachten konnte.
Vielen Dank!

Hallo,

hilft Dir das weiter?

The Corallus hortulanus - complex:

The revision of this complex is a bit older than some of the other revisions we have described, but we feel that it has quite some relevance, while a lot of Tree Boas still are treated as Corallus enydris or Corallus hortulanus without differentiating between the seperat species.

In 1996 (McDiarmid et al.) the species known by many as Corallus enydris (Linnaeus, 1758) was determined again to be a junior synonym of Corallus hortulanus (Linnaeus, 1758). The two species was described as Boa Enydris and Boa Hortulana in the 10th edition of Systema Naturae on respectively page 215 and 215-216. As the original describtion of both species was quit similar and without any significant differences to tell the species apart, the first revision of the species as Corallus hortulanus with Corallus enydris as a synonym by Duméril and Bibron in 1844 is to be used as the designation of the senior synonym.

The species Corallus hortulanus (or Corallus enydris as it was mainly called) was generally split into the two subspecies hortulanus (or enydris) and cookii.

Then in 1997 the major worker on this complex without a doubt, Robert W. Henderson, who has worked with these species for nearly to decades, published a taxonomic review of the hortulanus Complex, based on analyses of morphological characters and mtDNA (Henderson & Hedges, 1995) from over 600 specimens from the entire range of the complex. The result of this review was that the complex had to be split into the four species Corallus hortulanus (Linnaeus, 1758) , cooki Gray, 1842, grenadensis (Barbour, 1914) and ruschenbergerii.(Cope, 1876).

This new taxonomy of course gives some problems for hobbyists and scientists used to the old definition of the complex as a species with two subspecies. The old taxonomy for the complex had the nominatform living in the same area as is now the case for Corallus hortulanus. The subspecies cooki on the other hand has with this new taxonomy been split into three seperat species, which is the cause of confussion. What we used to call Corallus enydris cooki or C. hortulanus cooki could now be three different species. And probably the all belong to the nominat species, as both cooki and grenadensis has rather limited distributions and most of the contries in the range of C. ruschenbergeri are no large exporters of wildlife.

Amazon Tree Boa
Corallus hortulanus
Linnaeus 1758

Probably the most amazing of the Corallus, Amazon tree boas are truly gems of the snake world. Only rarely can you find a species that exhibits the diverse array of coloration and patterning that you see in Corallus hortulanus. There are individuals that are gray or black in color and then there are individuals that are the most stunning red, orange, or yellow. The variation is incredible. In Kaleidoscopic Tree Boas by Peter Stafford and Robert Henderson, there is a series of four photo plates showing four differently colored Amazon tree boas- all photographed along the same trail in Brazil.

But not only is the Amazon tree boa diverse in color and pattern but also in habitat. Its range is one of the largest of all the Boines. Before 1997, when the Amazon tree boa included C. cookii, C. grenadensis, and C. ruschenbergerii, its range stretched from Costa Rica into Bolivia and southeastern Brazil. Even with the elevation to species status of the aforementioned species, the range of C. hortulanus is still expansive- encompassing the entire Amazon rain forest as well as drier areas in southeastern Brazil. This large distribution exposes the Amazon tree boa to different habitats. While other species such as the emerald tree boa cannot utilize all the ecological niches, the Amazon tree boa has found ways to survive and succeed in many of these niches.

Perhaps what is most perplexing about the Amazon tree boa to new enthusiasts is the large quantities of both scientific and common names which have been applied to them. The Amazon tree boa, as it is currently known, is Corallus hortulanus. Formerly, it was Corallus enydris. And for the longest time, the species which are now C. cookii, C. grenadensis, and C. ruschenbergerii were all considered Cook's tree boas and placed as a subspecies of the Amazon tree boa as either C. hortulanus cookii or C. enydris cookii. So, according to Roy McDiarmid, T'Shaka Touré, and Jay M. Savage, Corallus enydris should be properly named Corallus hortulanus. And according to Robert Henderson, Corallus cookii is a species, not a subspecies, and Corallus grenadensis is a new species as well as is Corallus ruschenbergerii.

What does that all mean to you who keep Amazon tree boas? Here comes more confusion. Probably 99% of the individuals in the country are Amazon tree boas, Corallus hortulanus. Several decades ago now, a few importers began calling yellow Amazon tree boas "C. cookii". Then to add to the mix-up, some dealers also began calling garden phase Amazon tree boas "Cook's tree boas" and so a common pet trade animal, the "Cook's tree boa", became a very mis-identified animal and people became very confused. Both of these cases of "Cook's tree boa" should be called Amazon tree boa in a majority of cases. Only a very small number of true Cook's tree boas exist in the pet trade. Either way, you always get the attitude that has made Amazon tree boas so famous But their beauty and relative hardiness in captivity make them fascinating animals.

Hallo!

Wie bereits angedeutet hat Henderson Ende der neunziger den so genannten Corallus hortulanus Complex neu überarbeitet und die bisher beschriebenen Unterarten von Corallus hortulanus in den Art-Status erhoben. Seit dem spricht man also von Corallus cookii, die eigentlich keinen deutschen Namen hat, allerdings kann man sie auf Grund ihres endemischen Vorkommens auf der Insel St. Vincent als St. Vincent Boa bezeichnen. Für Corallus ruschenbergeri gibt es keinen passenden deutschen Namen.

Ich Hoffe etwas geholfen zu haben,

Christoph

Hallo!

Mir ist noch eingefallen, dass Trinidad Boa ein eventuell vertretbarer Trivialname für C. ruschenbergerii ist.
