INTRODUCTION
ThegenusMacromidiawas erected by Martinin 1907,with M.rapida as the

panand China(DAVIES & TOBIN, 1985; ASAHINA, 1964, 1978; FRASER,
1936;ISHIDAetal., 1991;LIEFTINCK, 1935,1971;WILSON,1996;ZHOU &
WEI, 1979;TSUDA,2000). Fourspecies, namely M. rapida Matin, 1907(Hong
Kong, Guangdong), M.kelloggi Asahina, 1978(Fujian), M. hangzhouensis Zhou
&Wei, 1979(Zhejiang) andM. ellenaeWilson 1996(Hong Kong)havebeenre-
