Sci., Tokyo, (45): 53–57, March 28, 2008 A Small Collection of Tingidae (Insecta: Heteroptera) from Sarawak, East Malaysia, with a Checklist of the Known Species Masaaki Tomokuni Department of Zoology, National Museum of Nature and Science, 3–23–1 Hyakunin-cho, Shinjuku-ku, Tokyo 169–0073, Japan E-mail: [email protected] Abstract. Ten species of Tingidae in nine genera are recorded from Sarawak, East Malaysia, on the basis of the specimens in the collection of the Sarawak Forest Research Centre, Kuchin, Malaysia, and the National Museum of Nature and Science, Tokyo, Japan. Brief notes on their tax- onomy and biology are given, if necessary. Of these, six species, Cantacader quinquecostatus (Fieber, 1844), Pseudophatnoma denticollis (Péricart, 1986), Belenus dentatus (Fieber, 1844), Eritingis recentis (Drake and Poor, 1937), Physatocheila brailovskyi Péricart, 1992, and Trachype- plus borneensis Péricart, 1986, are new to Sarawak. A checklist of the tingid species known from Sarawak is also provided for further studies toward the full inventory of this group.
