The first half of the winter has been a very interesting period at the Soutpansberg Centre for Biodiversity and Conservation. We have traveled widely to under sampled areas, spent a lot of time on the Northern Slopes and also enjoyed a fair bit of time at Lajuma and sunny Medike.

New Species for our Lists

During the last couple of months we have been working very hard looking for reptiles and meticuliously logging everything for our biodiversity surveys, amongst the 2406 records generated in just over two months, we managed to find some new species which is always exciting. 

The first new species for the period was a Horned Adder (Bitis caudalis) from the hot dry northern slopes. After finding a sloughed skin of the species earlier this year we have been working very hard to locate specimens for photography and finally we caught up with one. Although these snakes are common they are very difficult to see. Since the first find we have located another.

The second new species for the period was a rather big surprise, it was a juvenile Snouted Cobra. Anecdotal records indicated that the species did occur on Medike but we had not located them until May 2017 (note that we have been sampling since 2014). After the first we saw another, a very thickset two metre long adult, and a week later another. Very exciting!

The other new species we found this past winter have been the elusive Dwarf Sand Snake (Psammophis angolensis), we spotted this little beauty while walking along the track at Medike. Next surprise was finding the Cape Skink in some deep Kalahari Sands while sampling in the far western Soutpansberg. Another interesting find was locating Stevenson's Dwarf Gecko near Pafuri in the North East.

The final new species for our list was the Southern Brown Egg-Eater (Dasypeltis inornata). The Soutpansberg harbours a relicit population of these plain, yet beautiful snakes. These snakes are completely harmless and feed exclusively on bird's eggs. These new finds bring our total list of reptiles for the Soutpansberg to 103 species and we are confident that we will locate even more with hard work in the coming months.

  

Rarities and Soutpansberg Endemics and Special Finds

The Soutpansberg is a hotspot for reptiles with many unusual and exciting animals to be seen. Sometimes locating them can be difficult, but with time we eventually catch up with even the most secretive. The most unusual and rare sighting we witnessed over this early winter period was Giant Baboon Spiders (Harpactira gigas) mating in the wild. We moved a rock and saw the male near the females chamber, the male started drumming and approaching the female. The whole thing took about five minutes and the male ran away in the end. This was a once in a lifetime sighting and amazing to witness. The whole thing was filmed by Ryan Macdonnell from Canada.

Some of our highlights include: locating another rare Reticulated Centipede Eater (Aparallactus lunulatus), so far we have only located six individuals of this species at Medike which is a considerable range extension; finding a population of melanistic Cregoi's Legless Skinks (Acontias cregoi) near Punda Maria in the Kruger National Park; more localities for Lang's Dwarf Worm Lizard (Chirindia langi langi); obtaining a high altitude record for the Soutpansberg Purple-Glossed Snake (Amblyodipsas microphthalma nigra); a far western record for Savannah Lizards (Meroles squamulosus); and another locality for Jones's Girdled Lizard (Cordylus jonesii).

The Familiar

During Winter things are a bit slower and we tend to take more time with the animals we find and get some photographs of more common and visible species. Because our participants over the past two months were avid nature photographers we took a little more time to get some good images of the more common but still exciting Soutpansberg reptiles. As you can see we were lucky to see so many different species.
