Number: 447, Pages: 1 - 9
Thallisellites olgae gen. et sp. n. (Erotylidae: Languriinae, Thallisellini) is described from the Late Eocene Baltic amber. Extant species of the tribe Thallisellini are all of a neotropical distribution. The new genus is similar to the extinct Serramorphus Lyubarsky et Perkovsky, 2017 from Bitterfeld amber. The new genus differs from Serramorphus by the smooth, rounded and not dentate lateral margin of the pronotum (in Serramorphus, the lateral margin is sinuous and spinose). New genus is considered monotypic and differs from extant genera of Thallisellini primarily in the strongly developed anterolateral angles of the pronotum. Family Tarsonemidae (Acari) is reported from the Baltic amber for the first time.
