“…There are only a few species of Lepidoptera described from this class of amber (Sohn et al 2012). Representatives of the family Micropterigidae were encountered quite often in inclusions, and therefore, led to the descriptions of five species (Zhang et al 2017;Cockerell 1919) which were assigned to the extant genus Sabatinca (Walker, 1863). One species was described in Douglasiidae, a placement (Poinar 2019a) that needs to be confirmed.…”

We report some surprising recent distributional range extensions of one extant genus and two more families of primitive moths discovered in amber fossils from South-east Asia which were previously only known from Australia and/or the southwestern Pacific, with the possible exception of an undescribed Siberian fossil attributed to Lophocoronidae. During entomological field work in rain forests of central Vietnam a new species of Micropterigidae was discovered. It is described herein as Aureopterix bachmaensis sp. nov. based on male and female specimens collected at light in the Bach-Ma National Park. The identification was corroborated by a molecular analysis. This is the first record of this genus in the Northern Hemisphere, previously thought to be restricted to the Australian Region (including New Caledonia). First results of investigations of Burmese amber inclusions now reveal the presence of the Australian Region families Agathiphagidae and Lophocoronidae in the Cretaceous of Asia. The fossil taxon Agathiphagama perdita gen. nov., sp. nov. is established on the basis of two females and this is assigned to Agathiphagidae. The fossil genus Acanthocorona gen. nov. is established in Lophocoronidae and includes seven species described here as A. skalskiisp. nov., A. bowangisp. nov., A. muellerisp. nov., A. kuranishiisp. nov., A. sattlerisp. nov., A. spiniferasp. nov. and A. wichardisp. nov. The new species can be distinguished by the male genitalia which are illustrated together with wing venation and other morphological characters. The disjunct ranges of these taxa are discussed in a historical biogeographic context. Vicariance and dispersal hypotheses explaining the disjunct pattern are discussed. The discovery of these new species suggests a broader ancestral range of Aureopterix, Agathiphagidae and Lophocoronidae. Their extant ranges may be regarded as remnants or relicts of a wider distribution in the Mesozoic, or at least in the case of Aureopterix they could be the results of recent or ancient dispersal processes, since the calibration of molecular splits does not so far accord with plate tectonics.
