Twospeciesaredescribedasnewtoscience. One speciesisrecordedforthefirsttimeinChina. Keystothesubgeneraandspeciesofthe genusNephusaregiven. Key Words: CoIeoptera,CoccinelIidae,Scymnini, Nep/1tls. ThegenusNephusMuLsANTbelongstothetribeScymniniofthefamily Coccine1- lidae. Itsdistributionisworldwide,andabout200specieshavebeenknownin the worldup to thepresent. Some of them have been reported to play an important roleinregulatingthepopulationofmealybugsinfestingcitrustrees,coconuttrees, etc. All thetypespecimenstobedesignated in thispaper aredeposited in theSouth ChinaAgricultural University,Guangzhou.
