EvansetHyatt andCheiroseiusparbatensisEvansetHyatt

Lindquist & Moraza (2010)將鐮螨科分鐮螨亞科(Blattisociinae Garman, 1948)和扁綏螨亞科(Platyseiinae Evans, 1957)，共12個(gè)屬。扁綏螨亞科含3個(gè)屬：小手綏螨屬(CheiroseiulusEvans & Baker, 1991)，扁綏螨屬(PlatyseiusBerlese, 1916)和手綏螨屬(CheiroseiusBerlese, 1916)。Zhang & Fan(2010)報(bào)道我國該屬13種，其中中國大陸分布有9個(gè)種，臺(tái)灣分布有4個(gè)種。牙買加手綏螨CheiroseiusjamaicensisEvansetHyatt, 1960, 尼泊爾手綏螨CheiroseiusnepalensisEvansetHyatt, 1960, 和帕爾巴特手綏螨CheiroseiusparbatensisEvansetHyatt, 1960形態(tài)特征相似，為便于鑒定，現(xiàn)根據(jù)中國大陸標(biāo)本重新描述，并指出鑒別特征。文中測量單位為μm，括號(hào)內(nèi)為測量均值。標(biāo)本保存于福建省農(nóng)業(yè)科學(xué)院植物保護(hù)研究所。
