Abstract
Abstract. Two new fossil species of Baltocar Kuschel, 1992 and Pseudomesauletes Legalov, 2001 (Curculionoidea:
Rhynchitidae) are described from Eocene Baltic amber. Baltocar sontagae sp. nov. is similar to
B. groehni Riedel, 2012 but differs in the shorter rostrum, tarsomere 1 shorter
than tarsomere 5 and 1.4× as long as tarsomere 2, longer elytra,
and shorter body. Pseudomesauletes lobanovi sp. nov. is similar to P. culex (Scudder, 1893) and P. ibis
(Wickham, 1912): the new species differs from P. culex in the larger eyes, longer
pronotum, being 0.44× shorter than elytra, and slightly smaller body
size; from P. ibis it differs in the smaller body size, rostrum shorter than
elytra, and weakly convex pronotum. This is the first record of
Pseudomesauletes from Baltic amber and the sixth species of Baltocar. Keys to species of the genus
Baltocar and to the Eocene species of the genus Pseudomesauletes are given. Assumed trophic
relationships of these fossil taxa are discussed (urn:lsid:zoobank.org:pub:260EBE6E-DA6C-4D6D-A1D2-2C258224622F).
