摘要：
The byrrhid subfamily Lidryopinae subfam. nov. is proposed for Lidryops occultus gen. et sp. nov. described from Lower Cretaceous "opaque" amber originated from Archingeay-Les Nouillers, Charente Maritime, southwest France which was studied using propagation phase contrast X-ray synchrotron microtomography at the European Synchrotron Radiation Facility (Grenoble). This byrrhid subfamily differs from members of the closely related groups (Chelonariidae, Limnichidae, Dryopidae, Elmidae, Lutrochidae) in the set of characters including the moderately convex dorsuria, the subpectinate antennae, the five-segmented tarsi with strongly lobed tarsomeres 1-4, subsecuriform ultimate maxillary and labial palpomeres. An assumption on probable lifestyle of Lidryops occultus gen. et sp. nov. is proposed on the basis of structural peculiarities. A short review of the byrrhid fossil record and its analysis are made.
