Diagnosis

Rhysacephala is distinguished from other Xiphydriinae by the presence of 7-segmented maxillary palps, the fading out of fore wing vein 2A (both character states shared with the New Zealand Moaxiphia) and several other character states which distinguish it from Moaxiphia, including parallel inner orbits and enlarged hind claws of female. One undescribed species has fore wing vein 2A evenly pigmented (Jennings, unpublished).
