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.

Comparisons : Interesting termites of the genus Hospitalitermes have often been separated

into species by the colorations of antennae and head. These characters are, however, unstable

and gradually fade into paler and more yellowish in alcohol.

Species of the Hospitalitermes known to the author are separable by the key given below.

H. asahinai may be also close to luzonensis OsHIMA, schmidti AHMAD, papuanus AHMAD and

moluccanus AHMAD in having the antennae with similar relative length of segments, but the

first three species have basal humps of nasus, and moluccanus is larger. Chinese species of

Hospitalitermes recorded by Tsai and Chen, 1964, as luzonensis may be jepsoni SNYDER.

Name of this new species is dedicated to Dr. Syoziro AsAmNA, the leader of our coilecting

trip to Thailand.
