Ichneumon sarcitorius is another member of the Ichneumonini tribe featured in the NHM guide, described as a medium to large (female 10mm, male 14mm) black and red, or black and yellow species where the size, shape and precise colour patterns are distinctive.

The female abdomen has a wide red band followed by a narrower black band, a second narrower red band and then black until the white stripe just before the tip. The males are longer with broad white bands across the abdomen at the hind edges of the segments, with conspicuous indentations on the bands of the second and third segments. The bands on the first and fourth segments are usually broken. Both sexes have hind femora tipped with black.

It has recently been given the common name of the White-striped Darwin Wasp.
