TWO NEW SPECIES AND A NEW RECORD OF THE GENUS LIMNOPHORA FROM GUIZHOU,CHINA (DIPTERA:MUSCIDAE)

In this paper, two new species of the genus Limnophora R.-D. are described and figured. And a new record for China is added. The type specimens are preserved in the Health and Anti-epidemic Station of Guizhou Province. 1.Limnophora cyclocerca, sp. nov. (figs.l-5) This new species runs to Limnophora brunnescens Emden, 1965 in Emden's (1965) key, but differs from the latter in following characters rinterfrontalia almost parallel-sided; mesonotum without a pair of narnow grey or brownish grey paramedian vittae; m1 + 2 evenly; fifth abdominal segment on dorsal surface with a brown-dusted median vutta. Type locality :Guiyang (holotype , allotype , in copula). 2.Limnophora guizhouensis, sp. nov. (figs. 6-9) This new species runs to Limnophora triangula Fallen, 1825 in Hennig's (1960) key, but the male may be distinguished from that of the latter chiefly by having freepart of anal cerci rather narrow. Type locality :Shuiyang (holotype ). 3.Limnophora apiciseta Emden, 1965, new record. 1 male collected from Guiyang.
