The numbers of identified Osvoboditel Blvd., 1000 Sofia, species of the genera are for Graphomyia (1), Gymnodia (3), Hebecnema (4), Mydaea (12) and Myospila Bulgaria (2) species respectively. Two species of Gymnodia and two of Mydaea are newly recorded. Including the present contribution, there are now 25 species of Mydaeinae reported from Bulgaria. The findings are compared with records of neighbouring countries. Keywords: Bulgaria, Muscidae, Mydaeinae, new records, comparison Introduction [1] The catalogue on the muscid fauna of Bulgaria published by Lavčiev in 2003 is based on earlier published reports on Muscidae from Bulgaria and on his own observations. The compilation contains primarily general information about presence of muscidae species in Bulgaria and their flight activities, e.g. seasons of the year and height above sea level. Information such as numbers, sex, localities and dates of collected species is little and no information is given where the specimens are deposited. However, as the overview comprises at least the large majority of all earlier reports on the muscid fauna of the country, it has been chosen as basis to which the results of the present investigation on the distribution records of Mydaeinae-species in Bulgaria are compared. [2] The subfamily of Mydaeinae with less than 400 species all over the world is one of the smaller subfamilies of the Muscidae. It comprises in Europe six genera (Graphomya Robineau-Desvoidy, Gymnodia Robineau-Desvoidy, Hebecnema Schnabl, Opsolasia Coquillett, Mydaea Robineau-Desvoidy, Myospila Rondani) with 38 species reported by Fauna Europaea[3] and of which Pont [3, 4] listed in total 21 and Lavčiev [1] 19 species as known from Bulgaria. The present update records 22 species collected in Bulgaria in the period between 1925 and 2015. Of these Gymnodia humilis (Zetterstedt, 1860) and Gymnodia polystigma (Meigen, 1826) as well as Mydaea maculiventris (Zetterstedt, 1846) and Mydaea setifemur Ringdahl, 1924 are newly reported for the country. In total the number of Mydaeinae recorded from Bulgaria is raised now to 25 species. Material and Methods The present investigations have been conducted from April 2014 to August 2016 and are mainly based on the Muscidae collection of the Institute of Biodiversity and Ecosystem Research, Sofia (IBER) of the Bulgarian Academy of Sciences, Sofia. Additionally the Diptera collections of the National Museum of Natural History, Sofia (NMNHS) of the Bulgarian Academy of Sciences and of the Regional Natural History Museum of Plovdiv (RNHMP) have been screened for specimens of Mydaeinae. External morphological features were examined using a Zeiss Stemi 2000-C stereomicroscope. The large majority of the Mydaeinae-specimens have been found among the unidentified muscidae material of the collections of the three institutions mentioned above. For Correspondence examination of the material primarily the keys to the Muscidae of the Palaearctic Region by Eberhard Zielke Hennig [5] and additionally the keys to "The Muscidae (Diptera) of Central Europe" by Gregor Institute of Biodiversity and et al. [6] were used. The classification of the Muscidae as well as synonymizations applied by Ecosystem Research, Bulgarian Gregor et al. [7] in the very recently published "Manual of Central European Muscidae Academy of Sciences, 1 Tsar Osvoboditel Blvd., 1000 Sofia, (Diptera)" are also applied in this paper. Bulgaria The examined genera and their species are listed alphabetically and the sites, where the specimens have been collected, chronologically. ~ 310 ~ Journal of Entomology and Zoology Studies Names of collectors are mentioned as well as of those, who Hebecnema fumosa (Meigen, 1826): Material examined: 1♂ determined specimens in former years.
