摘　　要：记述了安徽省潜山盆地早～中古新世望虎墩组中发现的２属３种假古猬类化石，其中包括一个新种──望虎墩非猬（Ａｎｉｃｔｏｐｓ ｗａｎｇｈｕｄｕｎｅｎｓｉｓ ｓｐ． ｎｏｖ．）。新种不同于属型种大别非猬（Ａｎｉｃｔｏｐｓ ｔａｂｉｅｐｅｄｉｓ）在于下颊齿下前尖更衰退且更靠近下后尖，下次小尖不发育，ｍ３跟座呈圆形。上颊齿单面高冠现象较显著，相对横宽。The new materials of Pseudictopidae from Early to Middle Paleocene Wanghudun Formation of Qianshan Basin, Anhui are described in the present paper. They represent two genera and three species: Anictops tabiepedis Qiu,1977, Anictops wanghudunensis sp. nov. and Paranictops aff. P. majuscula Qiu, 1977. The new species differs from type species of the genus mainly in having relatively robust mandible and transversely wide cheek teeth, more reduced paraconid which is very near to the metaconid on lower cheek teeth, no notch in the middle of metalophid on p4 and no hypoconulid on the first two lower molars, m3 with short hypoconulid and round talonid. and relatively wide upper cheek teeth without distinct anterior cingulum. The difference between paranictops aff P. majuscula and Paranictops majuscula is mainly in the width of trigonids and talonids of the first two lower molars. In the former the talonids are wider than trigonids while in the latter species it is just the opposite. The new finds further demonstrate that pseudictopids were flourishing in the Early to Middle Paleocene of Qianshan Basin.
