Abstract
AbstractThe nemonychid, Libanorhinus succinus gen. & sp. n. represents the first weevil to be reported from Lebanese amber and the first formal description of a representative of the family Nemonychidae from any amber source. The specimen is placed in the extinct subfamily Eobelinae on the basis of its elytral punctures lined up to form striae, the presence of scutellar strioles and the possession of simple claws. The vertex of the head, antennal insertions at about the apical quarter of the rostrum and abdominal ventrites distinguish it from previously described fossil species in the Eobelinae. Since many extant nemonychids feed and develop in the male cones of representatives of the Araucariaceae, the present fossil could have developed in the cones of this resin-producing tree family.
