A new genus and species, Horakia kubani gen. n., sp. n., of Meligethinae from Thailand are described and compared with the closely related genus Cryptarchopria Jelínek. Cryptarchopria infima (Grouvelle) is recorded from the islands Ambon and Seram (Maluku, Indonesia), and its association with flowers of the palm Areca catechu L. is established for the first time. Diagnostic characters of the genus Kabakovia Kirejtshuk, 1979 are discussed, and Kabakovia latipes (Grouvelle, 1908) is recorded from Nepal for the first time.
Amphicrossus japonicus is the first known facultatively aquatic nitidulid. The adult beetles breed in bamboo sap and subsequently enter water-filled bamboo culms. In water they breathe via a ventral air sheath held by hydrofuge pubescence. The beetles are facultative predators and hunt mosquito larvae, which they grab with their forelegs. The trend to facultative predation in Cucujoidea and the transition for beetles in general from semi-liquid decaying organic matter into water is discussed.
The paper shows some results of the group of cryogenics and superconductivity, where low temperature devices are developed and realized. The group has built several cryostats and superconductivity magnets for NMR and other experimental systems. Nowadays radiative heat transfer at low temperatures is studied and the results are applied in cryogenics. Another subject of the present study is the cryopumping for ultra-high vacuum applications. and Hlavní náplní laboratoře nízkých teplot, založené v roce 1968, bylo využití jevu supravodivosti k vytváření silných homogenních magnetických polí pro potřeby NMR. Oborem nízkých teplot se zabývá současná skupina kryogeniky a supravodivosti. Předmětem jejího studia je m.j. měření přenosu tepla zářením za nízkých teplot a dosahování vysokého a čistého vakua kryočerpáním. V laboratoři vznikají další nízkoteplotní zařízení jak pro vlastní experimenty tak i pro jiná vědecká pracoviště.
