Distinction ofCheiroseiusjamaicensisEvansetHyatt,Cheiroseiusnepalensis

EvansetHyatt andCheiroseiusparbatensisEvansetHyatt

Lindquist & Moraza (2010)将镰螨科分镰螨亚科(Blattisociinae Garman, 1948)和扁绥螨亚科(Platyseiinae Evans, 1957)，共12个属。扁绥螨亚科含3个属：小手绥螨属(CheiroseiulusEvans & Baker, 1991)，扁绥螨属(PlatyseiusBerlese, 1916)和手绥螨属(CheiroseiusBerlese, 1916)。Zhang & Fan(2010)报道我国该属13种，其中中国大陆分布有9个种，台湾分布有4个种。牙买加手绥螨CheiroseiusjamaicensisEvansetHyatt, 1960, 尼泊尔手绥螨CheiroseiusnepalensisEvansetHyatt, 1960, 和帕尔巴特手绥螨CheiroseiusparbatensisEvansetHyatt, 1960形态特征相似，为便于鉴定，现根据中国大陆标本重新描述，并指出鉴别特征。文中测量单位为μm，括号内为测量均值。标本保存于福建省农业科学院植物保护研究所。
