Flavopunctelia flaventior is newly reported from Japan where it was collected in Nagano Prefecture and Hokkaido. Distribution of F. soredica extends north to Hokkaido as well as Yamanashi Prefecture, central Honshu, Japan. Source

We investigated the nest site and prey items of Isodontia auripygata (Hymenoptera: Sphecidae) in a subtropical forest on Iriomote Island, ca. 200 km east of Taiwan. I. auripygata used the cavity of a dead branch as their nest site, and the nest was composed of two cells that were divided by wood offcuts. Inside the branch, we found large-sized adult cockroaches, Rhabdoblatta formosana (Blattodea: Epilampridae), R. formosana adults were fed to an I. auripygata larva in each cell. To our knowledge, this is the third record of species of the genus Isodontia that prey on cockroaches. © 2016 Masato Ito et al. Source

The family Eosentomidae from Japan is revised. A new genus, Osientomon, is erected and a new species is ascribed to this genus. This new genus is characterized by the short, setiform sensillum g, absence of sensilla e and b'1 on foretarsus, and S-shaped processus sternalis and duck's head type caput processus on the female squama genitalis. Two new species are added to the genus Pseudanisentomon and 19 new species and 1 new record of the genus Eosentomon are described. As a result, 43 species belonging to 4 genera are now recognized from Japan. Taxonomic keys are provided for the identification of the genera and species from Japan. © 2010 · Magnolia Press. Source

The distribution and species assembly of Japanese Protura collected from forest soils were examined using published databases and statistical analysis. We used records from 3110 sites where 71 taxa were found. The species richness of Protura ranged from one to 16 species, and TWINSPAN analysis of regional populations indicated that the northern and southern regions could be separated into distinct groups. Three major species assemblages were identified by cluster analysis from points containing more than six species. Three groups reflected historical migration from northern and western linkages to the Asian continent. The northern assemblage showed a negative correlation to winter minimum temperature and the other two assemblages exhibited relationships to precipitation and temperature. Vegetation was not responsible for proturan distribution. These results suggest that the history of Protura invasion explains the biogeography of these soil-based, small arthropods and also that climate change will induce a shift in the distribution of species irrespective of changes in vegetation type. © 2012.
