NEW BABOON SPIDER SPECIES DISCOVERED IN KRUGER NATIONAL PARK

Martin Paulsen and Ian Engelbrecht have discovered a new species of baboon spider (Ceratogyrus paulseni) at Letaba region of the Kruger National Park. They said that the baboon spider comes from four different genera and it is difficult to tell the genera that the baboon spider may fall into. The baboon spider has a horn on its cephalothorax and the horn is similar to the common horned baboon spider (Ceratogyrus becaunichus). This discovery makes one to think about evolution and whether everything is still evolving. The discovery of the baboon spider forms part of the researches of South African National Survey of Arachnids (SANSA) headed by Dr Ansie Dippenaar-Schoeman of the Agricultural Research Commission (ARC). They are trying to discover and describe an inventory of the South African arachnoid fauna. There about 220 species of arachnoids found in Kruger National Park which are known. Kyle Harris, a C•I•B student is conducting a masters (M.sc) research on the “effects of alien invasive plants on spider assemblages within the KNP” [1].

  • Very Interesting BUT... is this simply an indigenous species not previously found or an Invasive species? You have posted this on the Invasives Blog - implying it is an invasive species which I think is not the case. Nevertheless this is interesting - a picture would have been nice - to see what it looks like?

    Finally it is important to identify yourself so I can credit you with participation in the course.

  • It was not previously found. these shows that we are still evolving because the baboon spider falls under four genera.

  • ok Lethabo, it is interesting in such a way that I need to read more about it.

  • Hey Lethabo!

    I hate to echo Richard, but the fact that they weren't previously found doesn't necessarily mean that they're invasive...

    I'm also having some trouble making sense of your comment... For one thing, I thought there were more than four genera of baboon spiders. For another, how does finding this new species show we're still evolving?

    But yep, it is interesting.

  • Hi - I think this is a species that had previously been unknown or un-described, not that it has evolved into a new species since the last time somebody studied them. Evolution still takes generations to change into a new species.
