Material examined. Type: holotype ♂: NEPAL: Katmandu, Bhurumche ( CNC). Other material. NEPAL: Ghanpokhara , 5500–7000 ft., 2.V.1954, J. Quinlan leg., 1♂ ( BMNH). Palaearctic: CHINA: Ningxia Hui Nationality Autonomous Region, Mt. Liupanshan National Forest Park , 21.VI–14.VII.2008, Jiemin Yao leg., 1♀, 1♂ ( SCAU); Ningxia Hui Nationality Autonomous Region, Jingyuan , Mt. Liupanshan , Longtan Forest Farm , 5.VII.2008, Jiemin Yao leg., 2♂ ( SCAU). A. querceus is known from many Palaearctic countries: Austria, Belgium, Finland, France, Germany, Italy, Japan, Malta, Norway, Sweden, The Netherlands, United Kingdom ( Olmi 1994, 1999a). The quotations of A. querceus from China by Olmi (1999a) and He & Xu (2002) are really related to Aphelopus albiclypeus Xu, He & Olmi.
