Holotype female, China: Zhejiang, Longquan City, Fengyangshan National Nature Reserve ( 27°53'N , 119°11'E ), 28. VII. 2007, collected by Guo-Quan Wang, from Schima superba Gardn.&Champ. ( Theaceae ). Paratypes, 8 females. Distribution. China (Zhejiang). Etymology. The species is named from the generic name of the type host plant. Remarks. This new species is similar to Gammaphytoptus zuihoensus Huang & Wang, 2004, but they can be easily separated as follows: in Gammaphytoptus schimae , median line is complete, setae h1 is absent and infesting Schima superba Gardn.&Champ.; in Gammaphytoptus zuihoensus , median line is incomplete, setae h1 is present and infesting Machilus zuihoensis Hay. var. zuihoensis ( Huang and Wang 2004 ).
