New or little known genera and species of the phyline plant bug tribe Hallodapini are documented. The genus Acrorrhin-ium Noualhier is reported from Thailand for the first time and diagnosed. Three new species, Acrorrhinium kranion, A. lancialium and A. tritonion, are described. The immature forms are confirmed for A. lancialium (5th instar) and A. trito-nion (4th instar); the latter species was found to be associated with Hibiscus tiliaceus L. The little known hallodapines in Asia, Alloeomimus muiri Schuh and Clapmarius thailandana Schuh, are also diagnosed. An annotated check list of the Hallodapini in Thailand and color digital images in life for all currently known Thai species are provided. Hallodapus brunneus (Poppius) is reported from the Oriental Region for the first time. Copyright © 2013 Magnolia Press.

One new species of flower bug, Scoloposcelis koreanus Jung & Yamada, sp. nov., that inhabits shiitake mushroom farms, is described from Gangwon-do Province, South Korea. Diagnosis, description and biological notes of the new species are presented, along with a key to the species of Scolopocelis from the Palaearctic Region. Copyright © 2011.

Eleven species of the ant-mimetic plant bug genus Pilophorus Hahn from Thailand are documented, with photographic images of live individuals. Four new species with conventional, moderate antlike shape, Pilophorus meteorus, P. saovapruki, P. subparallelus and P. suwimonae, are described. Two known Thai species, P. alstoni Schuh and P. typicus (Distant), are further reported and diagnosed. Biological information including host association is provided for P. alstoni, P. meteorus, P. saovapruki and P. typicus. A checklist of all currently known species of Pilophorus in Thailand and a key to known Thai species are included. Pilophorus typicus is reported from Singapore for the first time. © 2014 Magnolia Press.

The radiolarian zonation of the Izumi Group is revised for an integrated biostratigraphy across the Campanian/Maastrichtian boundary, together with the ammonite occurrence, fission track and magnetostratigraphic calibration of the acidic tuff key beds. The significance of direct correlation in the same sections, between macro- and micro-fossils (i.e. between relatively near-shore nektonic and turbiditic planktonic-fauna) is discussed in relation to the litho- and bio-facies of the Izumi group. Late Cretaceous paleoceanographic changes inferred from the studied radiolarian fauna represent a regional marker event for the chronostratigraphic correlation of continental shelf to turbidite deep-sea sequences, which accumulated on a mid latitudinal margin facing towards the NW paleo-Pacific. The proposed Campanian/Maastrichtian boundary is at the limit between Pachydiscus awajiensis and Nostoceras hetonaiense ammonite zones. This boundary corresponds to the radiolarian last occurrence of Amphipyndax pseudoconulus (=. A.enesseffi), Archaeodictyomitra sliteri, Dictyomitra formosa, D.koslovae and Rhopalosyringium magnificum at the top of the Myllocercion acineton Assemblage Zone (uppermost Campanian), and the first occurrence of Clathrocyclas gravis and Dorcadospyris sp. A, at the base of the Maastrichtian C.gravis Assemblage Zone. The new data settle partly a chronostratigraphic discrepancy between radiolarian and ammonite zonations in the Izumi Group, which was pointed out previously by Ishida et al. (2010). © 2015 Elsevier Masson SAS.

A new variety of Arundinella nepalensis (Poaceae), var. xerophila, is described. This variety is different from var. nepalensis in leaf size, inflorescence length, callus hair length, spikelet and habitat.
