An actinobacterium, designated strain 44C3(T), was isolated in Michigan, USA, from the hindgut of the larvae of Tipula abotominalis, an aquatic crane fly, and was subjected to a polyphasic taxonomic investigation. Phylogenetic analysis based on 11 rRNA gene sequences revealed that the strain represented a separate clade within the family Microbacteriaceae. It showed highest 11 rRNA gene sequence similarity with Cryobacterium psychrotolerans 0549(T) (96.5 %). Strain 44C3(T) had a novel B-type peptidoglycan. The peptidoglycan contained the diamino, acid lysine, the peptide Gly-D-Glu was detected in the partial hydrolysate and alanine was the N terminus of the interpeptide bridge. No other amino acids found in other B-type peptidoglycans (including diaminobutyric acid, ornithine, homoserine and hydroxyglutamic acid) could be detected. The major menaquinones were MK-12 and MK-11, the major fatty acids were ai-C-15:0, ai-C-17:0 and iC(16:0) and the DNA G + C content was 60.9 mol%. Analysis of the chemotaxonomic and phylogenetic data suggested that strain 44C3T represented a novel species of a new genus within the family Microbacteriaceae, for which the name Klugiella xanthotipulae gen. nov., sp. nov. is proposed. The type strain of Klugiella xanthotipulae is 44C3(T) (=DSM 18031(T) =ATCC BAA-1524(T)).
