Introduction 



This paper is the second of what we hope will be a series of revisions 

 of Oriental Ceratopogonidae, the first being a revision of the Oriental 

 Alluaudomyia by Wirth and Delfinado (1964). The ceratopogonid 

 material which has been sorted and mounted on slides from extensive 

 light trap collections brought to the U.S. National Museum for the 

 study by Wirth and Hubert (in preparation) on the Culicoides of 

 southeast Asia provides a source which we hope will facilitate badly 

 needed revisions of other genera of biting midges. 



This study is based on a total of 2,617 specimens of which 1,192 

 are mounted on slides. Types, including paratypes, were selected only 

 from slide-mounted material; the "Additional Specimens" in our 

 lists are also mounted on slides unless noted as "pinned" or "alcohol." 

 In "Distribution" the type locality is given first, followed by a 

 semicolon ; then the other localities are listed alphabetically or broadly 

 by general distribution patterns in the case of wide-ranging species. 

 In the locality data lists, the arrangement is alphabetical as far as 

 possible, with the country first (CAPITALIZED), then the State or 

 Province, district or town, etc. The English transliteration of Thailand 

 localities has been done as far as possible according to the Times 

 Atlas of the World. 



For their generous cooperation in collecting and sending us Oriental 

 material, we are especially indebted to the following persons and 

 institutions: H. C. Barnett, A. A. Hubert, H. E. McClure, and 

 R. Traub, associated with the Walter Reed Army Institute of Research 

 and the Medical Research Institute at Kuala Lumpur, Malaya; 

 D. H. Colless and R. H. Wharton, Commonwealth Scientific and 

 Industrial Research Organization, Canberra, Australia; M. E. 

 Griffith and D. R. Johnson of the Agency for International Develop- 

 ment, Washington, D.C.; J. L. Gressitt, T. C. Maa, L. W. Quate, 

 and C. Yoshimoto of the B. P. Bishop Museum, Honolulu; and 

 J. E. Scanlon and Manop Rattan arithikul formerly of the SEATO 

 Medical Research Laboratory, Bangkok. 



The types of our new species are deposited in the U.S. National 

 Museum in Washington and the B. P. Bishop Museum in Honolulu. 

 Paratypes, when available, will be deposited in the Bishop Museum, 

 Honolulu; British Museum (Natural History), London; Indian 

 Museum, Calcutta; School of Public Health, University of Sydney;
