What bug is this (1 Viewer)

I found this strange looking insect in my house in the east of Sierra Leone w. Africa. As a matter of fact it is hiding itself under a pile of chitin shields coming from agama lizard droppings( held together by cob web(??)) that it carries on its back. I managed to undo it from the rubble with a soft watercolor paint brush. who knows what this bug is? and is the web made by the animal or just like the chitin collected on his path?

It looks like a bug of some sort, probably a nymph. Some assassin bugs (Reduviidae) disguise themselves like this but I can't tell from these photos if that's what it is.

Thanks for helping me in the right direction. With only about 10% of the African insects described the chance that it has not got a name yet is considerable. Reduviidae are mentioned as present in W.Africa but there is no mention of the family on the Sierra Leone checklist yet. I have now added it to my checklist.
