The species is characterized by small body size and yellow to yellowish red body coloration with distinctly infuscated legs. Additionally, the taxonomic status of all known members of the Cataglyphis livida complex is updated. Cataglyphis lutea Pisarski, 1967, stat. rev. is raised to the species level and Cataglyphis viaticoides (Andr\é, 1881) is proposed as a senior synonym of Cataglyphis livida bulgarica\  Atanassov,\  1982,\  syn.\  nov.\  and\  Cataglyphis\  albicans\  mixtus\  (Forel,\  1895),\  syn.\  nov.\  Finally,\  a\  provisional key to members of the livida complex is provided.

A taxon considered in past years as P. pallescens sensu Radchenko is described as a new species: Plagiolepis perperamus sp. nov. based on material from Eastern Mediterranean. Its morphological separation from P. schmitzii Forel, 1895, the second species characterized by dense gaster setosity, is supported by study on their environmental niches. Plagiolepis pallescens Forel, 1889 is redescribed based on type specimens and material collected from various localities spread within Balkans. Its taxonomical status is clarified and a definition of a \‘pallescens group\’ is improved and supplemented. Plagiolepis maura var. taurica Santschi, 1920 and Plagiolepis maura var. ancyrensis Santschi, 1920 are synonymized with Plagiolepis pallescens Forel, 1889.

The invasive garden ant Lasius neglectus (Hymenoptera: Formicidae) has been spreading rapidly in Europe ever since the 1990s. This ant established enormous supercolonies in many European cities and poses a serious threat to the local native faunas. The spread of this species has not slowed down in the last decades, but in the recent years the sizes of the known L. neglectus populations have generally been declining or have stagnated. For 29 supercolonies checked in four countries, in 10 cases L. neglectus individuals have not been found on the former area of their occurrence. On the other hand, only two supercolonies have expanded. In this paper, we summarize these monitoring data collected by the personal independent, diligent monitoring activities of myrmecologists on populations of the invasive garden ant in Bulgaria, Hungary, Poland and Spain. The reasons for this collapse are thought to be: (1) depletion of the local resources, (2) gradation of pathogens and (social)parasites, (3) climatic factors, (4) intra-population mechanisms, (5) confrontation with highly competitive native species, and (6) lack of suitable nesting microhabitats. As similar phenomena were observed in the cases of supercolonies of other invasive ant species, it seems that they decline more generally than has been thought.

Application of Numeric Morphology-Based Alpha-Taxonomy (NUMOBAT) demonstrated the existence of three cryptic species within the Westpalaearctic Lasius paralienus species complex: L. paralienus Seifert, 1992, having a wider European distribution north to Sweden, L. casevitzi sp. nov., an endemic of Corsica, and Lasius bombycina sp. nov. from southeast Central Europe, the Balkans and Asia Minor. Hierarchical NC-Ward clustering and non-hierarchical NC-k-means clustering of 16 morphological characters resulted in 98.7\% identical classifications within 76 examined nest samples of the three species. The classification error in 180 worker individuals was 0\% in a linear discriminant analysis (LDA) and 1.3\% in a LOOCV-LDA. Differential characters to other species groups and an identification key of the six European members of the Lasius alienus F\örster species group are provided.

The ant fauna of Strandzha (Istranca) Mountain and its Black Sea coast was investigated in both Bulgaria and Turkey. A total of 90 ant species were determined. Oxyopomyrmex krueperi Forel, 1911, Stenamma striatulum (Emery, 1895), Camponotus tergestinus M\üller, 1921 and C. universitatis Forel, 1890 were recorded for the first time in Bulgaria and 34 species are new for the Bulgarian part of Strandzha Mountain. Four ant species \– Temnothorax crassispinus (Karavaiev, 1926), T. interruptus (Schenck, 1852), Tetramorium hungaricum
(R\öszler, 1935) and Tapinoma madeirense Forel, 1895 are new for Turkey. Ten species were recorded for the first time from the European part of Turkey and 38 \– from the Turkish part of Strandzha Mountain. The zoogeographical composition and conservation status of threatened ant species are discussed.

Three Mediterranean ant species \– Camponotus aegaeus EMERY, 1915, Camponotus gestroi EMERY, 1878 and Crematogaster auberti EMERY, 1869 \– were found on Bulgarian territory for the first time. The report of Camponotus aegaeus for Bulgaria is the first for continental Europe as well. The total number of known ant species for Bulgaria increases to more than 160.
