Host–parasite interactions are ideal systems for the study of coevolutionary processes. Although infections with multiple parasite species are presumably common in nature, most studies focus on the interactions of a single host and a single parasite. To the best of our knowledge, we present here the first study on the dependency of parasite virulence and(More)
The lomechusine genus Myrmedonota Cameron is recorded from North America for the first time. Myrmedonota is diagnosed, and two new species, M. aidani Maruyama & Klimaszewski, sp. nov., and M. lewisi Maruyama & Klimaszewski, sp. nov., are described and illustrated. Bionomical information is provided for both new species.
Three methods for molecular typing of methicillin-resistant Staphylococcus aureus using polymerase chain reaction (PCR) were compared. The method which amplified the variable number of tandem repeat of dru sequences grouped the isolates into six types. Whereas, the method examining restriction fragment length polymorphism of coagulase gene and the method(More)
Foldable wings of insects are the ultimate deployable structures and have attracted the interest of aerospace engineering scientists as well as entomologists. Rove beetles are known to fold their wings in the most sophisticated ways that have right-left asymmetric patterns. However, the specific folding process and the reason for this asymmetry remain(More)
Ant crickets (Orthoptera, Myrmecophilidae) are typical ant guests that obtain nourishment from the ants in their nests. Some ant crickets are host-specific, whereas other species are host-generalists. We investigated the behavioral polarization between the specialist cricket Myrmecophilus albicinctus and generalist Myrmecophilus formosanus. In the field, M.(More)
A taxonomic revision of the subgenus Coprochara Mulsant & Rey, 1874 of the genus Aleochara Gravenhorst, 1802 in Japan is presented. The following three species are recognized: Aleochara (C.) verna Say, 1833, A. (C.) binotata Kraatz, 1856 and A. (C.) squalithorax Sharp, 1888, of which A. binotata is new to Japan. All previous records of "A. (C.) bipustulata(More)
Ants of the genus Lasius are ecologically important and an important system for evolutionary research. Progress in evolutionary research has been hindered by the lack of a well-founded phylogeny of the subgenera, with three previous attempts disagreeing. Here we employed two mitochondrial genes (cytochrome c oxidase subunit I, 16S ribosomal RNA), comprising(More)
Termitotrox cupidosp. n. is described from Cambodia and represents the first discovery of Termitotrox Reichensperger, 1915 from the Indo-Chinese subregion of the Oriental region. The type series was collected from fungus garden cells of Hypotermes makhamensis Ahmad, 1965 (Isoptera, Termitidae, Macrotermitinae). Hypotermes Holmgren, 1917 was previously an(More)
Jubogaster towai gen. et sp. nov. is described from a colony of Pheidole xanthogaster Wilson (Hymenoptera: Formicidae) in the Peruvian Amazon. The new taxon is amongst the largest pselaphine species known. Its transverse head implies an affinity with Trogastrini (Pselaphinae: Euplectitae), but J. towai lacks typical characters diagnostic for trogastrines(More)
The fauna of myrmecophilous rove beetles associated with Aenictus laeviceps (sensu Wilson 1964) at Lambir Hills National Park, Sarawak, Malaysia was investigated. Eight species belonging to six genera of the subfamily Aleocharinae including the following new taxa are recorded and/or described: Myrmecosticta exceptionalis Maruyama gen. et sp. nov.,(More)
