Definitely Gymnosoma but I can't go any further than that because they are a very difficult genus - even with a specimen. The genitalia and the degree of dusting on the frons and the thorax are all very significant features when making an identification Smile

AS Chris rightly put it, difficult to tell.
It does not look like rotundatum, more likely either clavatum or dolycoridis. However, this is guesswork and not science.
In any case, a male.

This is definitely NOT rotundatum, but either dolycoridis or maybe clavatum. It helped, but the conclusion remeans the same.
