| Abstract: | The Glandulariini (=Cyrtoscydmini) is today the largest, most species-rich and most diverse tribe of Scydmaeninae comprising over 70% of the extant species of this subfamily. Named genera and species of Glandulariini are known mostly from Miocene to Eocene ambers, with only one, recently described Mesozoic taxon. Here we report the second genus of Glandulariini from Upper Cretaceous Burmese amber, Cenomaniola Ja?oszyński and Yamamoto, gen. nov., with two species, C. carinata Ja?oszyński and Yamamoto, sp. nov. and C. macrophthalma Ja?oszyński and Yamamoto, sp. nov. Cenomaniola shows the general body plan typical of the ‘Euconnus complex’ within Glandulariini, with thick bristles on the sides of head and pronotum, a character conserved for nearly a hundred million years. With the previous discovery of Scydmobisetia Ja?oszyński and Yamamoto, two major body forms typical of the extant Glandulariini are already proved to have differentiated in or before the Late Cretaceous. This demonstrates early origins and a long conservation of ‘Euconnus-like’ and ‘Sciacharis/Horaeomorphus-like’ body plan in the currently largest group among Scydmaeninae. |
