Two new species of Tasiocera Skuse from Baltic amber (Diptera, Limoniidae).

The paper presents very rare fossil record of crane flies. Inclusions in Baltic amber have documented the second evidence of the existence of the genus Tasiocera (Diptera: Limoniidae: Chioneinae) in ancient epochs of Earth's history. Hypotheses were also introduced regarding the environmental preferences of fossil Dasymolopilus in relation to modern representatives of the subgenus. The genus is numerous in species and widespread in the modern fauna, while only one species, Tasiocera (Dasymolophilus) circumcincta, has been known from the fossil record to date. The paper presents an additional description and graphic documentation of this species based on new materials. The discovery of two other species Tasiocera (Dasymolophilus) gorskii sp. nov. and Tasiocera (Dasymolophilus) baltica sp. nov. in Eocene resins documents the occurence of Tasiocera since Eocene. Interestingly, only subgenus Dasymolophilus is represented both in extinct and extant fauna while subgenus Tasiocera is not known from the fossil record. The new discovery is very significant, and the result of the study adds a brick to our understanding of the evolution of this group of insects and their habitat.

Early stage of evolution of Gonomyia (Diptera: Limoniidae), new significant discoveries in the Cretaceous Iberian and Kachin amber.

Thanks to detailed studies of inclusions in Spanish and Kachin amber, it was also possible to study the morphology of insects belonging to the genus Gonomyia. A new material under investigation made it possible to establish two new nominative for science subgenera within the genus Gonomyia has been designated with unique set of characters of antenna, wing venation and genitalia. Two new species within two new subgenera have been described and documented by drawings and photographs, there are Gonomyia (Iberiana) penalveri subgen. et sp. nov. and Gonomyia (Cretagonomyia) burmitica subgen. et sp. nov. The new discovery is the first record of the genus Gonomyia (Diptera: Limoniidae) in Cretaceous Spanish amber and the second in Kachin amber. The new discovery adds to the knowledge of the crane fies' diversity and evolution, especially its first stage in the Cretaceous.
