Cratosmylus magnificus gen. et sp. nov., type genus and species of the new osmylid subfamily Cratosmylinae, is described from the Lower Cretaceous of the Crato Formation, Brazil. The relationships of this taxon remain uncertain within the Osmylidae, mainly due to the lack of phylogeny of the whole family. Nevertheless, it shares with the Mesozoic subfamily Saucrosmylinae the Rs curved and bent anteriorly distally, even in a more pronounced state, i.e. Rs touching R1 in its distal part. 相似文献

A new weevil, Aepyceratus hyperochus gen. et sp. nov., Aepyceratinae subfam. nov., is described from mid-Cretaceous Burmese amber. The new subfamily differs from the previous Mesozoic subfamilies Brenthorrhininae, Eobelinae, Cretonemonychinae and Paleocartinae by the short lateral pronotal carina, stark convex eyes and basal antennal insertion. From the subfamilies Rhinorhynchinae and Cimberidinae, it is distinguished by the short lateral pronotal carina, exodontous mandibles and basal antennal insertion. The new subfamily differs from the subfamily Idiomacerinae by the distinct clypeolabral suture, elliptical protruding eyes, short antennomere 1, wide tarsi, short lateral carina on the pronotum, and exodontous mandibles. 相似文献
