Psyllids (Hemiptera: Psylloidea) in the entomological collection of the National Museum of Natural History, Bulgarian Academy of Sciences

Abstract

The entomological collection of the National Museum of Natural History at the Bulgarian Academy of Sciences in Sofia (NMNHS) preserves a total of 89 specimens representing 25 species of jumping plant lice (Hemiptera: Psylloidea). These were recorded and digitised in the Specify platform as part of the Distributed System of Scientific Collections project (DissCo-BG). This paper summarises all available data on these specimens. Twenty-four species were collected in Bulgaria, one species in Greece. Voucher specimens for Psylloidea published in a historical treatise on the Bulgarian fauna of Hemiptera by Dimitar Joakimov were not found in the NMNHS and are most likely lost. However, Joakimov’s collection, later acquired and supplemented by the museum, contains unpublished material, including three species reported here for the first time from Bulgaria: Aphalara maculipennis Löw, 1886, Cacopsylla ulmi (Foerster, 1848) and Dyspersa abdominalis (Flor, 1861).
