Two nests of the wasps Leptochilus alpestris (de Saussure, 1855) and Leptochilus regulus (de Saussure, 1855) collected in the Crimea were described. The nest of L. alpestris was found in the empty snail shell of Monacha fruticola under a stone; it contained one cell sealed with plug made of glued gravel bits. The nest of L. regulus was found in 3 mm hole of a reed stem from trap-nest; it contained 9 cells separated with partitions made of gravel and mud. The unusual larval habit was discovered in L. regulus - they moved mud from the plug of the cell to its bottom before cocoon spinning. Distinctions of the studied nests from ones of the other species of the genus Leptochilus de Saussure, 1853 were discussed.

Omalus sculpticollis as the Main Enemy of Psenulus fuscipennis (Hymenoptera, Chrysididae, Crabronidae) in the Crimea, Ukraine. Martynova K. V., Fateryga A. V. - Th e trap-nest technique was tested in the Karadag Nature Reserve (Crimea, Ukraine). In the result the enemies of Psenulus fuscipennis (Dahlbom, 1843), which caused damage to its progeny, were revealed: Omalus sculpticollis Abeille, 1878, Melittobia acasta Walker, 1839, Perithous septemcinctorius (Th unberg, 1822), and Trichodes apiarius Linnaeus, 1758. Th e structure of the parasite complex, voltinity of the species, comparative eff ectiveness of enemies are determined on the basis of observed data. Th e taxonomical position of O. sculpticollis is discussed, its sexual dimorphism is illustrated, the detailed description of the cocoon and some structural features of the last instar larva are given for the fi rst time. Feeding habits of the larvae of O. sculpticollis are examined and the delicate aspects of interaction with the host are discussed. Short notes on terminology are given.

The paper deals with problems of taxonomy, reproduction, and distribution of the diatom Nitzschia longissima. Based on the analysis of literature data, as well as studying the type material and 36 clones collected on the Atlantic coast of France and in the Black Sea (region of Karadag), the authors propose to apply N. longissima to the concept sensu stricto, which, in their opinion, will eliminate many problems that have accumulated in the identification of this species. © Begell House Inc., 2014.
