Six Japanese species belonging to the genus Marshall, 1898 (Hymenoptera, Braconidae) were recorded and photographed. Three species, Belokobylskij, Schmiedeknecht and Tobias (= Luo & Chen ), are new to Japan, and a new species, is described. An identification key to the Japanese species of is also provided. In addition, new host records are provided, i.e., Chao reared from and (Alydidae) and reared from (Pentatomidae). The Alydidae is a newly recorded host family of .

The genomes of human gut bacteria in the genus Bacteroides include numerous operons for biosynthesis of diverse capsular polysaccharides (CPSs). The first two genes of each CPS operon encode a locus-specific paralog of transcription elongation factor NusG (called UpxY), which enhances transcript elongation, and a UpxZ protein that inhibits noncognate UpxYs. This process, together with promoter inversions, ensures that a single CPS operon is transcribed in most cells.

Type material of species belonging to the weevil tribe Celeuthetini Lacordaire, 1863 mainly from Sundaland, Sulawesi and the Lesser Sunda Islands was studied. Mitochondrial sequence data could be obtained for 27 old type specimens, providing important evidence on their systematic placement. Various taxonomic problems evident from molecular and morphological data are remedied.
