A revised checklist of 309 taxa (including unknown species) of Philippine mosqui1981-1982 toes is compiled from various sources including additional materials from found mosquito surveys in the Philippines. In total, nearly 40% of the mosquito fauna listed only in the Philippines, such endemicity is conspicuous especially for the genera Tripteroides (94%) and Zeugnomyia (75%) and the subgenera Finlaya (78%) and Armigeres (60%). INTRODUCTION (Miyagi et al., unpublished data), and some unknown species. Therefore, these new materials should also be included. As Basic’s 1971 checklist is about 15 years old, "it obviously needs updating. The present checklist incorporates the information that has become available since Basic’s publication. Such a checklist would greatly facilitate researchers and other personnel who deal directly or indirectly with the Philippine As part of the overseas research activities on phylogenic studies of mosquito fauna in Southeast Asia mosquito surveys in the Philippines were carried out by a Japanese research team in cooperation with the Malaria Eradication Service, Ministry of Health, Republic of the Philippines in 1981-1982. A previous checklist of Philippine mosquitoes listed a total of 260 mosquito species (and subspecies) (Basio, 1971). Additional taxonomic treatments of species, such as synonymy, elevation to valid species, transfer to another genus or subgenus, and new distribution records have been reported by various investigators. Some of these changes are introduced and cited in a catalogue of the world mosquitoes (Knight & Stone, 1977) and its supplements (Knight, 1978; Ward, 1984). These references are useful and important for surveys but the world catalogue is too bulky and inconvenient for quick retrieval of .information on Philippine mosquitoes. In addition, there are several new taxonomic treatments and new records of the Philippine mosquitoes by various authors (Abercrombie, 1977; Baisas, 1974; Huang, 1978a. 1979;Mattingley, 1981;Peyton, 1972, 1977; Reinert, 1973a, b, 1974, 1976, 1982; Sirivanakarn, 1972,1973a, b, 1976,1977). Our field surveys in the Philippines resulted in the collection of 135 taxa including 3 new species, Culex azurini, Topomyia cabrerai and Tripteroides riverai (Miyagi et al., 1983b, c; Toma etal., 1984), 5 new distribution records mosquitoes. MATERIALS AND METHODS Mosquito species are arranged taxonomically from the Genera Anopheles to Toxorhynchites in order of subfamilies, tribes, and genera. For ease in retrieval, an arrangement of subgenera, species and/or subspecies within each genus is based on alphabetical order rather than taxonomic relationships is used. Mosquito surveys were carried out mainly in Puerto Princesa and Iwahig on Palawan Island, near Tuguegarao on Luzon Island and in Mt. Apo and Davao on Mindanao Island in 1981 1982. Our own collections and a preliminary list of Philippine mosquitoes based on Basio (1971), Knight & Stone (1977), Knight (1978) and Ward (1984) are major sources of the present list. For the distribution of mosquitoes in the Philippines, the name of islands instead of provinces (adopted by Basio, 1971) is used. When a mosquito species is widely distributed throughout the country, the sign (W) is used 149 r for convenience to avoid listing so many names of islands. The italic names of the islands indicate the type localities of the species. An asterisk against the mosquito name indicates that it is an endemic species of the Philippines. to (Eumelanomyia); Cx. brevipalpis: (Neoculex) to (Eumelanomyia); Tp. nepenthicola: (Rachionotomyia) to (Tricholeptomyia); Tp. mabini: (Rachisoura) to (Tripteroides); Tp. rozeboomi: {Tripteroides) to (Rachionotomyia); Tp. apoensis, barraudi, belkini, christophersi, delpilari, microcala, roxasi and women: (Triperoides) to (Tricholeptomyia). In the case of Ae. (Adm.) vexans nocturnus, Reinert (1973b) synonymised it with vexans but Lee et al. (1982) treated it as a valid species. Here we tentatively consider nocturnus as a subspecies of vexans according to Basio (1971). Cx. (Neo.) nematoides was adopted by Basio (1971) probably by mistake RESULTS AND DISCUSSION To the Philippine mosquito fauna of 260 species (and subspecies) listed by Basio (1971), 49 species are newly added but 20 taxa are changed from his list because of changes in taxonomic position as shown in Table 1. In addition, subgeneric changes of Table 1. ^ Main taxonomic changes* in the name of Philippine mosquitoes Names used by Basio (1971) Updated names An. (Ano.) insulaeflorum An. (Ano.) pilinotum An.

Of the valid taxa (and some unknown species) listed in Table 2 there are 309 species belonging to 18 genera: 41 species of the 150 Table 2.
