Very large specimens of T. graeca ibera were found in Bulgaria, but mostly in the 20th century. Presently, such tortoises are almost absent in the country. Here we summarise data about the largest spur-thighed tortoises registered in Bulgaria and provide information about five new large-sized individuals. We also draw attention to the fact that large specimens can hardly be found in the country today and discuss some possible negative effects of the extinction of these specimens on the existing populations. The maximum straight carapace length of the largest T. graeca ibera ever found in Bulgaria was ≈ 389 mm, but the maximum straight carapace length of the newly measured tortoises was 298 mm. Considering the rarity of such tortoises in the country today, the genes that determine the potential to reach larger sizes may gradually disappear. Thus, the institutions responsible for the conservation of nature should pay attention to areas where the presence of large-sized individuals has been established. This might help preserve the natural genome of T. graeca ibera in the country and therefore the existence of large individuals.

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 However, Joakimov’s collection, later acquired and supplemented by the museum, contains unpublished material, including three species reported here for the first time from Bulgaria: Aphalara maculipennis Löw, 1886, Cacopsylla ulmi (Foerster, 1848) and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).

We summarise the distribution of the two species of the genus Natrix occurring in Bulgaria, based on records from 147 peer-reviewed publications, grey literature, and data repositories, combined with unpublished data. This is the first extensive mapping for N. natrix; records fall in 560 cells of the 10-km MGRS/UTM grid, of which 102 cells (18.2%) were with published information we could not confirm with new data, 175 (31.2%) were with published and confirmed, and 283 (50.5%) were with new localities. For N. tessellata we increased the number of cells with records by 64% compared to the 2011 mapping, by identifying 445 cells with localities: 162 cells (36.4%) were previously published and unconfirmed, 152 (34.1%) were published and confirmed, and 131 (29.4%) were with new data. Gross climatic conditions for records with exact locations were assigned following the Köppen-Geiger classification; the distribution for both species does not seem to be highly correlated to climate as they were found in 9 of the 12 Köppen-Geiger classes present, only missing from the 3 classes that are limited to high elevations in Bulgaria and account for less than 1% of the area. The vertical distribution of the observations supports our knowledge that the species are most numerous at lower elevations (92.4% of records were <1000 m above sea level for N. natrix and 92.6% were <500 m for N. tessellata). Higher elevations and some lowlands remain relatively understudied and future sampling will likely reveal new localities for both species.

The checklist of louse flies or keds from the family Hippoboscidae in Romania with 14 species is given. Among them, six species have been newly recorded from Romania, from Natura 2000 site “Dunele Marine de la Agigea” Natural Reserve; namely: Icosta minor (Bigot in Thomson, 1858), Ornithoica turdi (Olivier in Latreille, 1812), Ornithomya chloropus Bergroth, 1901, Ornithomya fringillina Curtis, 1836, Ornithophila gestroi (Rondani, 1878), and Ornithophila metallica (Schiner, 1864). Out of the total, seven species are autochthonous, while the other seven are probably non-native species, either spreading invasively or only occasionally being imported to Romania or migrating to the country along with their hosts. Three new host-parasite associations have been reported for the first time. Specifically, the eastern olivaceous warbler Iduna pallida (Hemprich et Ehrenberg, 1833) represents new host species for I. minor and O. turdi, while the willow warbler Phylloscopus trochilus (Linnaeus, 1758) represents a new host species for O. gestroi.

Testate amoebae Cyclopyxis puteus Thomas (1960) has a characteristic morphology, that makes the possibility of overlook or misidentification unlikely. Although this species has been found worldwide, its morphology, biometrics and ecological preferences are poorly understood. In this study, isolated material from Bulgaria was investigated by using light and scanning electron microscopy. Based on morphological and biometrical data, we provide an improved diagnosis of this enigmatic species. A summary of the geographical distribution and ecological preferences is provided.

Entonaema is a peculiar and morphologically easily recognised fungal genus with disjunct and predominantly tropical-subtropical distribution. Entonaema cinnabarinum is typified on material from Australia and is the sole known species in Europe. It was first reported on this continent three decades ago, based on a collection from Bulgaria and remains so far one of the utmost rare European fungi with merely five sites known on the continent. After diligent search, the Bulgarian Entonaema was rediscovered in the area where it was first collected, and new sites were also found. Two ITS rDNA sequences of Bulgarian collections were obtained, appearing to be the first verified accessions of European origin. In the phylogenetic inference they appear closely related to an accession from South Korea, dubbed E. splendens. The outcomes of the phylogenetic analysis confirm the self-standing status of Entonaema, but its precise affiliation within the order Xylariales remains to be assessed further. Morphological characterisation, ample macroscopic and microscopic illustrations, as well as SEM images of ascospores of the new Bulgarian findings are included.

The sensitivity of ground beetles to changing habitat conditions makes them a good indicator of environmental change. The shift in their distribution could be used as an early warning signal for natural disturbances due to climate change. To reflect and monitor these changes, initial information is needed on carabid taxa in different high-altitude habitats, including the endemic and climate-sensitive tertiary relict coniferous forests of Pinus peuce (Macedonian pine) and Pinus heldreichii (Bosnian pine). Data on the carabid beetles in the different coniferous habitats in Bulgaria are scattered in various faunistic or taxonomic publications, and there is no exact information about their taxocoenoses in the Macedonian and Bosnian pine habitats. The present study aims to clarify the species composition and diversity patterns of ground beetles in these habitats in Bulgaria. Six sample sites were selected: five natural forest stands in the Rila Mts and Pirin Mts and one forest plantation in the Vitosha Mts. A total of 18 species and subspecies typical of forest habitats were recorded. Five of them were endemic to Bulgaria and five to the Balkan Peninsula. The most common species and the eudominant in the majority of the sample sites was Calathus metallicus aeneus. The exception was one of the Bosnian pine sample sites. Here, the dominant species was Xenion ignitum. The ground beetle species found in the studied forests were mostly zoophagous, mainly crevice or burrowing stratobionts in leaf litter, rocks and soil, a few epigeobionts, one botrobiont and one mixophytophagous geohrotobiont. The classification of the carabid taxocoenoses according to their qualitative composition showed two main clusters: the first being the carabids from the studied sites of the Vitosha and Rila Mts, and the second being the taxocoenoses from the Pirin Mts. The Bosnian pine habitats provide more favourable conditions for the high-altitude ground beetles, where they are in a state of equilibrium with higher species richness and evenness compared to those inhabiting the Macedonian pine forests. The forest communities of Pinus peuce and Pinus heldreichii in Bulgaria are of high conservation importance for the ground beetle and an even higher level of protection of these habitats is required.
