1 ,jyj',l'\lijhi~ BulL Gov. For. Exp. Sta. No. 257, 1973 Termites f:rom Thailand" By Katsura MORIMO'I'CP' Sn:mm n y : The present paper deals with the termites of Thailand colle<.oted in June, l9g5, in connection with the Japan- U. S. Cooperative Science Programme. Fourty eight species are ermmerated, of which four are new to science and thirteen are new to the fauna of Thiland. New species are : Glyj)totermes thaitandis, Nasutitermes brachynastdti..,, Termes major and Hospitaiitermes asahina( The present paper deals with the termites of Thailand. Survey was carried out in June, 1965, in connection with the Japan U. S. Cooperative Science Programme. A smaij. collection made by Mr. Y. WATANABE, of Kyoto University, has also been incorporated in this study. Termites of Thailand had been very poorly investigated until the excellent monograph made by AnMAD (1965). HoLMGREN (1913) first recorded five species from Thailand and SNYDER (1949) listed six species in his catalogue of the termites of the world. AuMAn's monograph contains 74 species and 19 species were enumerated by HARRis (1968). The present paper deals with 48 species, of which :four arc new to science and 13 are new to the fauna of Thiland. Altogether, 90 species of termites have been recorded from T'hailand up to the present. The survey described herein was carried out by Dr. S. AsAHtNA, of the National Institute of Health, Mr. Y. MtYATAKE, of Osaka Municipal Museum of Natural History, Dr. P. AsnwcK, of the Bernice P. Bishop Museum, and the author, with the cooperation of Mr. ArHIRAT Arunin and the staff of Department of Entomology and Plant Quarantine, Ministry of A.griculture, ThaD.and. To these entomologists the author wishes to express his deep gratitude. He 0\ves a particular debt to.mr. CnoTo Suvipa.kit for his assistance extended to us during our stay in Thailand. His thanks are also extended to Dr. V. HARRJs and Dr. W. A. SANDs, of Termite Research Unit, Commonwealth Institute of Entomology, for their kindness during his study in London, where the author identified most of the termites treated in this paper_ His thanks also go to Dr. K. ho and ML K. 0DA, of the Goverment Forest Experiment Station, for their kindness in the course of the present study. Holotype specimem; are in the collection of the Entomological Laboratory, Faculty of Agriculture, K.yushn University, and paratypes will be deposited.in the collections of the Bernice P. Bishop Museum, British Museum (Natural History) and the American Museum of Natural 1-l.istory. All the measurement~; in this paper are in millirnetres. * Studies on the xylophagous insects. 2.
