A total of 432 species of the family Tachinidae has been established in Bulgaria so far. The most speciesrich are the zones between 200 and 800 m a.s.l. [291-298 species (67.5-69.1%)]. The greatest number of species has been found in the zone of the xerothermic oak forests (333 species or 77.3%). The tachinid fauna can be divided into two main groups: 1) species with Mediterranean type of distribution (63 species - 14.6%), more thermophilic and distributed mainly in the southern parts of the Palaearctic and the lower parts of the mountains; 2) species with Palaearctic and Eurosiberian type of distribution (369 species - 85.4%), more eurybiontic and widely distributed. The distribution of the zoogeographical categories in the different vegetation belts of Bulgaria is scrutinised. The tachinid fauna is compared with the neighbouring countries and Mediterranean Africa. [ABSTRACT FROM AUTHOR]

Totally, 190 species of the family Tachinidae belonging to 96 genera and 4 subfamilies have been recorded from the Korean Peninsula. Their distribution is analysed and an areographical characteristics of the species are presented. Four species are endemics. The tachinids belong to 52 zoogeographical categories, divided into 2 main groups: (1) species with Manchurian type of distribution (82 species – 43.2 %) – more thermophilic and distributed mainly in the southern parts of the Palaearctic. The species of the southern type, distributed in the Palaearctic and beyond it, can be formally associated to this group as well; (2) species with Holarctic and Palaearctic type of distribution (108 species – 56.8 %) – more cold-resistant and widely distributed in the Palaearctic. The species of the northern type, distributed in the Palaearctic and beyond it, can be formally related to this group as well. The lack of geographical barriers allows mixing of the Palaearctic and Oriental fauna and determines the high percentage of the oriental taxa (47.4 %) in Korea. More than half of the species (106 species – 55.8 %) are distributed in the Oriental Region. [ABSTRACT FROM AUTHOR]

Currently, 260 species of the family Tachinidae, belonging to 122 genera and four subfamilies, have been recorded from the Mediterranean Africa. Their distribution is analysed and an areographical characteristic of the species is presented. A total of 31 species is known only from the Mediterranean Africa, while 229 species have been found also beyond it. The tachinids belong to 61 zoogeographical categories, divided into two main groups: 1) species with Mediterranean type of distribution (140 species - 53.8%) - more thermophilic and distributed mainly in the southern parts of the Palaearctic. The species of the southern type, distributed in the Palaearctic and beyond it, can be formally related to this group as well; 2) species with Holarctic and Palaearctic type of distribution (120 species - 46.2%) - more cold-resistant and widely distributed in the Palaearctic. The species of the northern type, distributed in the Palaearctic and beyond it, can be formally related to this group as well. The zoogeographical character of the fauna of Tachinidae is determined by the first group (inversely to the European). The limiting role of the deserts in the migration of tropical forms to the north is conspicuous. [ABSTRACT FROM AUTHOR]

Totally, 3368 species belonging to 84 families of the suborder Brachycera have been reported from Bulgaria. The families Tachinidae (425 species), Syrphidae (303 species), Muscidae (267 species), Phoridae (231 species) and Dolichopodidae (214 species) comprise the greatest number of species. Of the recorded species, 21 are pests on the forestry or agriculture and 49 species have a significance for the human or veterinary medicine. The distribution of dipterans in the different regions of Bulgaria is presented. The greatest number of species has been found in the zone of the xerothermic oak forests (2275 species or 67.5%). The brachycerans belong to 139 zoogeographical categories, divided into 2 supergroups: (1) species with Mediterranean type of distribution (384 species or 11.4%) - more thermophilic and distributed mainly in the southern parts of the Palaearctic and the lower parts of the mountains; 2) species with Palaearctic and Eurosiberian type of distribution (2916 species or 86.6%) - more eurybiontic and widely distributed. Totally, 68 (2.0%) endemics have been found. The distribution of the zoogeographical categories per vegetation belts of Bulgaria is scrutinised. [ABSTRACT FROM AUTHOR]
