Švábi z myanmarského jantaru a jejich fylogenetický význam

Šmídová, Lucia

The dissertation presents an analysis of the cockroach fauna preserved in mid-Cretaceous Myanmar amber (98.9 Ma) also known as Burmese or Kachin amber. This study is key to understanding the evolutionary history of this insect order and brings new details in resolving the phylogeny of cockroaches. The work also reveals that most genera are known exclusively from Burmese amber. Certain genera are found to a lesser extent at other world sites, within Laurasia and Gondwana. 76 species described from Burmese amber demon- strate a remarkable spectrum of ecological and physical specializations, indicating the evolutionary adaptability of cockroaches. The families Alienopteridae and Umenocoleidae exhibit transitional characteristics, suggesting close relationship. The family Liberiblat- tinidae is known from 7 species in 3 genera. The family Blattulidae includes 4 species, with the genus Oceloblattula also found in Lebanese amber. The families Corydiidae and Blattidae exhibit morphological similarities, exemplified by species such as Bubosa poinari. Endemic families such as Manipulatoridae and Fractaliidae have specific ecological roles that were replaced by other insect groups in the course of evolution. The family Mesoblat- tinidae is recorded with six species, including some with preserved oothecae....
