A taxonomic review of the fungivorous tetratomid beetles in Korea, which comprises four species belonging to two genera of two subfamilies, is presented. Three species, Holostrophus (Paraholostrophus) orientalis Lewis, 1895 and two newly recorded species, Pisenus insignis (Reitter, 1889) and Holostrophus diversefasciatus Pic, 1921, are identified and described herein. A photograph of adults, diagnoses, illustrations of diagnostic characteristics, and ecological information regarding habitat, and host fungi are provided.
The beetle family Ciidae, represented by Octotemnus laminifrons Motschulsky, 1860 and Octotemnus japonicus Miyatake, 1954 is presented for the first time in Korea. The beetle family Ciidae Leach is a relatively moderate family, which comprises about 640 described species in 42 genera worldwide. This family is distributed throughout the world. Ciids are minute fungus-feeding beetles, which are associated with the mycelia and fruiting bodies of wood-rotting fungi. These beetles are considered mycetobiont because they depend upon the basidiocarps for food and breeding throughout their life span. And also ciids are important components of the saproxylic fauna of many forests ecosystems and a number of species are considered rare or threatened and are associated with old growth forests or undisturbed forest conditions. A habitus photographs of adults, description, illustrations of diagnostic characters, and host fungi are provided.
Anthracene appended new host compounds have been synthesized by imine reaction. Fluorescent open chain host compounds Trisanthryl-tris(2-aminoethyl)imine 1 was synthesized from the reaction of tris(2-aminoethyl)amine and anthracene-9-carboxaldehyde in EtOH. Tris-10-chloroanthryl-tris(2-aminoethyl)imine 2 was synthesized from tris(2-aminoethyl)amine and 10-chloro-9-anthraldehyde in EtOH. The structures of all reaction product were identified by 1H NMR, 13C NMR, GC/MS, FAB Mass, IR spectrum and DSC. Cation complexation behavior was investigated by fluorescence spectroscopy measurements. The capability of transition metals cation recognition between fluorescent open chain host compound 1, 2 were investigated with Co²+, Ni²+and Cu²+. The fluorescence intensity was increased by host compounds corresponding guest cations. The relative order of fluorescence intensity changes were Co²+ > Cu²+ > Ni²+ . Compound 2 is very sensitive fluorescent sensor of Co²+ ion.
