Rhondes atypicus is an endemic species of jumping spider in the genus Rhondes that lives in New Caledonia. First described in 2016 by Barbara Patoleta, the species has been found on both Grande Terre and Isle of Pines, living in rainforests. It is small and slender, with a wide brown hairy cephalothorax and thinner abdomen. The abdominal markings differ between the male and female, which gives rise to the species name. The male has light and dark patches on its abdomen, and has a longer and thicker embolus than other species in the genus. The female, which is larger, has a striped abdominal pattern, which distinguishes the species from the similar Rhondes flexibilis.
