Cratichneumon sexarmillatus (Kriechbaumer, 1891)

= syn. Cratichneumon albiscuta (Thomson, 1893) , synonymized by HORSTMANN (2006a: 14)

Another Cratichneumon sp. with a black and white colouration, the males closely resembling the abovementioned species (but the clypeus and several tarsi are white). Our specimen was a female, feeding on umbellifers. The frontal orbits are conspicuously white. All tibiae have distinctive white rings, strongly contrasting with the tarsi and other parts of the legs. It is a bigger species, measuring approx. 14–18 mm ( RASNITSYN & SIITAN, 1981). Furthermore, just like C. armillatops it appears to be genuinely rare.

First report for Belgium; unconfirmed in the Netherlands.
