A new species of the genus Eustigmaeus (Trombidiformes: Prostigmata: Stigmaeidae) and the first record of E. extremiorientalis in Japan.

A new stigmaeid mite species Eustigmaeus imadae sp. nov. (Trombidiformes: Prostigmata: Stigmaeidae) is described from Japan.

Unveiled species diversity of moss-feeding mites (Stigmaeidae: Eustigmaeus): a research on their distribution, habitat, and host plant use in Japan.

The genus Eustigmaeus Berlese, 1910 represents the unique phytophagous group within the superfamily Raphignathoidea. Four species within this genus have been known to inhabit mosses and feed on them as larvae, nymphs, and adults. However, the interactions with mosses have remained poorly understood.

Recent origin and diversification accompanied by repeated host shifts of thallus-mining flies (Diptera: Agromyzidae) on liverworts and hornworts.

Despite the vast diversity of phytophagous insects that feed on vascular plants (tracheophytes), insects that feed on bryophytes remain understudied. Agromyzidae, one of the most species-rich phytophagous clades in Diptera, consists mainly of leaf-mining species that feed on tracheophytes. However, a recent discovery of thallus-mining species on liverworts and hornworts within the group of Phytomyzinae provides an opportunity to study host shifts between tracheophytes and bryophytes.

Diversity underfoot of agromyzids (Agromyzidae, Diptera) mining thalli of liverworts and hornworts.

Agromyzidae is a dipteran family that has diversified as internal plant feeders. Although most agromyzid species feed on herbaceous angiosperms, only a limited number of species has been recorded as miners of bryophytes. Extensive searches and rearing of bryophytivores in the Japanese Archipelago were made, resulting in that thallus-mining agromyzids are overwhelmingly widespread and diverse on thalloid liverworts and hornworts.

Immobilization of a flavin molecule onto poly(methacrylic acid)s and its application in aerobic oxidation catalysis: effect of polymer stereoregularity.

The isoalloxazine ring system, called flavin, was successfully immobilized on poly(methacrylic acid)s, PMAAs, with different tacticity post-polymerization modification under suitable conditions. The resulting flavin-containing polymers showed catalytic activity for aerobic oxidation reactions, in which the polymer stereoregularity clearly influenced their catalytic activity.
