The second representative of the family Eulohmanniidae Grandjean, 1931 was collected from East Japan. New subspecies has rostral tip with two deep round concavities, a short transversal suture between rostral and lamellar setae, three pairs of supracoxal setae (e. eI, eII), epimeral setal formula (3-1-4-4) and tarsus I with a small semicircular protruding anterior to seta tc'.

The species definition of Spherillo obscurus (Budde-Lund, 1885) was redefined based on observations of syntype and specimens collected from a broad-leaved forest in The University of Tokyo (Hongo Campus), Japan. The species definition of S. dorsalis (Iwamoto, 1943) was also modified based on the specimens collected from a broad-leaved forest in Yokohama National University, Japan. Partial DNA sequences of mitochondrial cytochrome oxidase subunit I and 12S and 16S ribosomal RNA and of nuclear 18S and 28S ribosomal RNA were determined for identifying these species.

Biological mineral weathering induced by soil ecological engineers : The case of earthworms and termites

Soil macro-invertebrates such as earthworms (Oligochaeta) and termites (Isoptera) are regarded as soil ecosystem engineers which affect the availability of resources to other organisms through their modifications and turbations of the physical environments. In spite of great awareness of their bio-physico-chemical influences on soil forming processes, it has been hardly recognized that these ecosystem engineers directly or indirectly have a significant impact on weathering of soil minerals. The direct effects include physical breakdown of mineral particles or chemical alternation by secretions derived from the engineers, while the indirect influences originate from symbiotic microbes which produce organic acids and enzymes that dissolve soil minerals. This paper reviews available literature on the influence of soil ecosystem engineers with a focus on earthworms and termites on weathering of soil minerals and discusses further challenges and future prospects on this topic.
