Three new species of Scolytoplatypus Schaufuss from China, and notes on the movement and functions of the prosternal processes (Coleoptera: Curculionidae: Scolytinae).

Three new species from China (Yunnan), Scolytoplatypus costatus Gebhardt Beaver, S. geminus Gebhardt Beaver and S. peniculatus Gebhardt Beaver, are described and compared with related species of the genus.

New species and new records of Schaufuss (Curculionidae, Scolytinae) from China, and resurrection of (Tsai & Huang, 1965) as a distinct species.

This study describes two new species, Liao, Lai & Beaver, and Liao, Lai & Beaver, , reinstates (Tsai & Huang, 1965) from synonymy with (Blandford, 1893), and records five species for the first time from China, Blandford, 1898, Gebhardt, 2006, Hagedorn, 1904, Eggers, 1939, Maiti & Saha, 2009, and three from mainland China, Gebhardt, 2006, Beaver & Liu, 2007, Hagedorn, 1904. A key to the males of species in China is given. Genetic data from four genes indicate a rather isolated position for both new species, although their genetic relationship to each other was close.

The red-listed species Thamnurgus rossicus in East Europe is a synonym of the rare Central European species, T. petzi (Curculionidae: Scolytinae).

The taxonomic status of Thamnurgus rossicus was evaluated with respect to the morphologically similar T. petzi using genetic markers. Nucleotide data from the mitochondrial COI gene revealed 2.

Dryadomyces amasae: a nutritional fungus associated with ambrosia beetles of the genus Amasa (Coleoptera: Curculionidae, Scolytinae).

During surveys of woodlands in Taiwan a previously undescribed fungus Dryadomyces amasae gen. sp. nov.

Conidial development in selected ambrosial species of the genus Raffaelea.

Conidiogenesis of the type species and two additional species of the genus Raffaelea Arx & Hennebert are described. In contrast to previous conclusions based on light microscopy that indicate sympodial production of the conidia, we found that conidium development was by annellidic percurrent proliferation in the type species Raffaelea ambrosiae, as well as in Raffaelea arxii and Raffaelea albimanens. Consequently, this mode of conidium development is similar to the conidiogenesis of anamorphs within the Ophiostomatales, but distinguished by sporodochia formed within the genus Raffaelea.
