A new species, a new synonymy, a revised generic assignment and new records in some African and Palaearctic Aradidae (Hemiptera: Heteroptera).

The late Ludvík Hoberlandt left several specimens of African Aradidae (Hemiptera: Heteroptera) in the collection of the National Museum in Prague which were labelled as new synonyms or types of new species, but, however, the corresponding taxonomic acts and decisions have never been published. As a result of their examination, Hoberlandt's 'Aradus africanus n. sp.' is identified as A. gracilipes Linnavuori, 1978, 'A. nuristanicus n. sp.' as A. betulae (Linnaeus, 1758), and 'Aradus intermedius n. sp.' is recognized as a new species, described here as A. congoensis sp. nov. (from the Democratic Republic of the Congo). Mezira lindemannae Kormilev, 1974, syn. nov., is synonymized with Brachyrhynchus abyssinicus Bergroth, 1895. The generic placement of Mezira amplicollis Linnavuori, 1978 in Brachyrhynchus Laporte, 1832 is confirmed. The status of 'Carventus machadoi n. sp.' (member of Burgeonia Schouteden, 1919; Angola) and 'Neuroctenus arnoldi n. sp.' (Zimbabwe), two additional putatively new species recognized by Hoberlandt, remains unresolved, pending the revision of the respective genera. The following new distributional records are given: Aradus gracilipes from Chad, Aradus betulae from Afghanistan, and Brachyrhynchus abyssinicus from Democratic Republic of the Congo, Guinea and Kenya.

The Oriental flat bug genus Libiocoris Kormilev, 1957 revisited: re-examination, synonymy, and description of a new genus (Heteroptera, Aradidae).

Re-examination of type specimens of LibiocorisKormilev 1957, L.poecilus from New Guinea and other taxa assigned to this genus, the Chinese Libiocorisheissi Bai, Yang & Cai, 2006 and Libiocorissinensis Bai, Yang & Cai, 2006 proved to be synonyms, thus L.heissi = L.sinensis syn. n. They are, however, different from Libiocoris Kormilev, 1957 to which they were originally assigned and a new genus Paralibiocoris gen. n. is proposed for them. Therefore Paralibiocorisheissi comb. n. = Libiocorisheissi Bai et al., 2006 = Libiocorissinensis Bai et al., 2006, syn. n. From Hainan Island, China, the following new species, P.roundangulus sp. n., P.hainanensis sp. n., and P.limuensis sp. n., are described and figured and a key to species is provided.

The external scent efferent system of selected European true bugs (Heteroptera): a biomimetic inspiration for passive, unidirectional fluid transport.

In this work, we present structured capillaries that were inspired by the microstructures of the external scent efferent system as found in different European true bug species (Pentatomidae and Cydnidae). These make use of small, orientated structures in order to facilitate fluid movement towards desired areas where defensive substances are evaporated. Gland channels and microstructures were investigated by means of scanning electron microscopy and abstracted into three-dimensional models. We used these models to create scent channel replicas from different technical substrates (steel and polymers) by means of laser ablation, laser structuring and casting. Video analysis of conducted fluid-flow experiments showed that bug-inspired, artificial scent fluid channels can indeed transport different fluids (water solutions and oils/lubricants) passively in one direction (velocities of up to 1 mm s-1), while halting the fluid movement in the opposite direction. At the end of this contribution, we present a physical theory that explains the observed fluid transport and sets the rules for performance optimization in future work.
