Popis: A rare species, Doryphoribius zyxiglobus, was found in mosses in New Zealand. So far, it has been cited only three times; from Australia, New Zealand and central China. The original description is very brief and is insufficient by today’s taxonomic standards and seems not to be based on the holotype. A photograph of the slide mounted holotype (obtained from The Museum of New Zealand) showed it to be so poorly preserved and oriented that it was deemed probable that little would be gained by its further examination. Consequently, the redescription was based on a few limited measurements from the photograph of the holotype with a complete set of measurements of a paratype and supported by morphometric analysis of a set of topotypes - all borrowed from The Museum of New Zealand. A comparison between sets of specimens from three countries (New Zealand, Australia and China) and a single specimen from South Africa permitted an evaluation of the geographic variation of this species. This paper thus redescribes D. zyxiglobus, reports on populations from widely separated locales and extends its geographical range.
