Jumping Spiders for ID from Zambia... Quite a Few.

I have a problem.

 

The problem is that regardless of the wealth of information available on the internet, that available on Afrotropical invertebrates is rather more of a poverty. This isn't quite so troublesome for more universally popular animals such as butterflies, but where it comes to just about anything else, I seem incapable of getting beyond family without assistance.

 

Spiders are proving particularly troubling - and, jumping spiders being particularly diverse, they are especially so. And so I turn here...

 

 

Uncertain as to whether any progress is likely, I'd sooner not fill up the forum with threads on unidentifiable spiders, so until I learn the chances of a firmer identification, I'm going to upload in threads per family (if I can)

 

First: This bears a resemblance to imaged of Thyena inflata, but I don't know whether this is a particularly distinctive species, so a resemblance may be meaningless. Chongwe District, Lusaka Province. August 2011

 

Second: No idea, but it looks like I miniature Toy Pom. Chongwe again, August 2011.

 

Third: Possibly Menemerus? Chongwe in August, yet again (a pattern develops). I did (rarely) take images of alternate angles.

 

Fourth: No idea again. Still Chongwe. September 2011.

 

Fifth: Still no idea, but this time Lusaka city, in October 2011. I also have an image showing the face of this one, if it helps.

    • Hello  Will.

      I think your shots are great and I am a huge fan of Jumping Spiders. I think that although it may be extremely frustrating you will have to catch the clever little blighters in a clear container that will enable you to photograph them (perhaps over a 1mm scale like graph paper) all in similar well lit conditions. This way you can get shots of the cephalothorax, abdomen and underside too.

      Best wishes and good luck. Lewis

            I'm glad you found ID's for most of your photos. I recently created a website for South African Salticidae : www.jumpingspiders.co.za

            Perhaps it can be of help in the future. :-)

            Regards

              Thank you for the lovely comments. :-)

                  I'm not an expert but your beautiful spider definitely looks like an Asemonea sp. to me. Unfortunately I can't help with the species. I have however found that it is sometimes difficult to ID species from descriptions (apparently the spiders lose some of their colour when placed in alcohol and by the time the taxonomists describe a species the colours may be different from when the spider was alive). There could also be colour variation within the same species. I once caught a light, lime green Asemonea and when I wanted to photograph it a couple of days later, the colours of the spider had changed completely (see the male Asemonea clara on my website).

                  Wish I could be of more help.

                  I'm very glad that you enjoy and use my website.

                   

                  All the best.
