[email protected] ABSTRACT Two new species of Dictyogenus Klapálek, D. jurassicum sp. n., endemic to the Jura Mountains of France and Switzerland, and D. muranyii sp. n., endemic to the French Vercors and Chartreuse Massifs, are described from adult, larva, egg characters and molecular markers. Information on the distribution, ecological preferences and conservation status of these new species is also provided. Identification keys for adults and larvae of Dictyogenus are proposed.
