Stenus aterrimus Erichson, 1839, streng myrmecophil mit Formica-Arten assoziiert, erwies sich als ein Komplex aus sechs Arten, von denen fünf jeweils wirtsspezifisch an eine Formica-Art gebunden sind. Für die sechste Art ist dies unbekannt, kann aber hypothetisiert werden. Die Untersuchung des Lectotypus zeigte, dass S. aterrimus die Art ist, die mit Formica truncorum Fabricius, 1804 assoziiert ist. Die folgenden fünf Arten werden neu beschrieben: Stenus polyctenicola sp. n. (locus typicus: Deutschland, Mecklenburg-Vorpommern, Altwarp; Wirtsameise Formica polyctena Förster, 1850), Stenus ruficola sp. n. (locus typicus: Deutschland, Brandenburg, Forst Bredow bei Brieselang; Wirtsameise: Formica rufa Linnaeus, 1758), Stenus pratensicola sp. n. (locus typicus: Deutschland, Brandenburg, Eberswalde; Wirtsameise: Formica pratensis Retzius, 1783), Stenus spielfeldensis sp. n. (locus typicus: Österreich, Steiermark, Spielfeld-Straß in Steiermark; Wirtsameise: wahrscheinlich Formica sanguinea Latreille, 1798) und Stenus sarajevensis sp. n.

Stichodactyla Haddoni

The response of nematocytes in the anemone Stichodactyla haddoni to contact with complex organic compounds varies according to the 9ubstance concerned and in most cases according to the level of accompanying mechanical stimulation. Compounds with a proteinaceous moiety differ in their capacity to excite nematocytes, but usually tend to induce a stronger response than polysaccharides or lipids. Nematocyst discharge against foreign animals appears to be the result of a sophisticated cellular recognition process in which the nematocytes, and/or cells closely associated with them, respond to physical contact with a surface of appropriate chemical composition.

ABSTRACTThe natural scale of insect navigation during foraging makes it challenging to study under controlled conditions. Virtual reality and trackball setups have offered experimental control over visual environments while studying tethered insects, but potential limitations and confounds introduced by tethering motivates the development of alternative untethered solutions. In this paper, we validate the use of a motion compensator (or ‘treadmill’) to study visually driven behaviour of freely moving wood ants (Formica rufa). We show how this setup allows naturalistic walking behaviour and preserves foraging motivation over long time frames. Furthermore, we show that ants are able to transfer associative and navigational memories from classical maze and arena contexts to our treadmill. Thus, we demonstrate the possibility to study navigational behaviour over ecologically relevant durations (and virtual distances) in precisely controlled environments, bridging the gap between natural and highly controlled laboratory experiments.
