整理1979～1996年采自中国四川省西部的蝇类标本中,发现蝇科三新种:树棘蝇属PotamiaRobineauDesvoidy,1830一新种:鬃跗树棘蝇Potamiasetitarsissp.nov.;胡蝇属DrymeiaMeigen,1826一新种:四川胡蝇Drymeiasichuanensissp.nov;池蝇属LimnophoraRobineauDesvoidy,1830一新种:灰黄池蝇Limnophoracinerifulvasp.nov。模式标本存北京军事医学科学院医学昆虫标本馆。
The present paper deals with three new species of Muscidae,collected from the western region of Sichuan Province during the years 1979～1996, belonging to the genus Potamia Robineau Desvoidy, 1830, Drymeia Meigen, 1826 and Limnophora Robineau Desvoidy, 1830, i.e. Potameia setitarsis sp.nov., Drymia sichuanensis sp.nov. and Limnophora cinerifulva sp.nov. The type specimens are kept in the Medical Entomological Specimen Building, Academy of Military Medical Sciences, Beijing, China. 1 Potamia setitarsis sp.nov.(Figs.1～3) ♂:Body length 8 0 mm. Allied to Potamia diprealar Fan et Kong, 1991, but, can be distingushed from the latter in frons width slightly wider than distance between posterior ocelli inclusive; interfrontalia sunk; ten infraorbital setae and intercalative hairs, three reclinate supraorbital setae; cross veins r m and m m unclouded; apex of vein r 1 not reaching level of cross vein r m; dorsum of abdomen with broad median vitta, but without lateral markings; both of inner and outer apical processes of cerrci developed (Fig.2). ♀:Unknown. Holotype ♂,Mt. Erlang(Forest farm, 2 740 m;29°53′N,102°10′E),Sichuan, China; 10 June 1987, collected by Feng Yan. 2 Drymeia sichuanensis sp.nov.(Figs.4～6) ♂:Body length 5 5～6 5 mm. The new species is very similar to Drymeia fumipennis (Malloch, 1921),but differs from the latter in following features:notopleura without accessory seta; posthumeral bristle 1:0; frons about half the width of 3rd antennal segment; interfrontalia about half as diameter of front ocellus or obsolete at the narrowest part;sternopleural bristle 1:3, although the lower two weak; fore tibia with 2～3 pv bristles at mid part and without av britle preapically; hind tibia with 7～10 pd bristles and 4～5 pv bristles; abdomen no obvious stripe. This new species is closedly related to Drymeia gongshanensis (Fan, 1992) too, but differs from the latter in following features:frons at the narrowest part about 1 5�
