【摘要】 <正> 近年来我们在闽北山区进行调查工作中,在光泽、浦城和邵武等县捕获到一定数量的东方田鼠（Microtus fortis）和花松鼠（Tamiops swinhoei monticolus）,并从其体上采到一些革螨,经过整理,发现其中有两种系科学上未记载的新种,现分别描述如下: 东方上厉螨Laelaps（Hyperlaelaps） orientalis新种（图1—6） 雌螨 体呈宽卵圆形,棕黄色。长0.73—0.80毫米,宽0.52—0.60毫米。背板一块大而完整,几盖住整个背部,有明显的肩部。板上一般具37对背毛,缺I₂和I₃。但有时其他的背毛如ET₁、ET₂和I₁等更多还原

【Abstract】 Laelaps (Hypelaelaps) orientalis sp nov. (Figs. 1-6)Female: Idiosoma broadly oval, length 0.73-0.80 mm, width 0.52-0.60 mm. Dorsal plate oval, bearing 37 pairs of setae, L and Is absent. Sometimes ET1, ET2 or I1 absent too. F1 and F2 rather small, M1-M5 short spiniform, M6-M11 long and simple. D7-D8, S6-S8 minute. Pilus dentilis sickle-shaped, with two long setae on the base of digitus mobilis. Sternal plate with convex anterior margin and deep concave posterior margin. St2 and St3 and Vl1 with blunt and cut off tip.Male: ET2 and L always absent, sometimes T1 and D3 absent too. Spermatodactyl long, with slightly curved sharp tip. Holoventral plate seperated from anal plate and bearing 10 pairs of setae. Holotype female and allotype male off Microtus fortis in April and September 1975, respectively.The differences between L. (H.) orientalis sp. nov., L. kochi, L. arvalis. L. amp-hibius and L. pachypus are given in the table.Holotype, Allotype, Paratypes 14(?). 9(?) all deposited in Fukien Provincial Anti-epidemic & Health Station.Haemolaelaps anomalis sp. nov. (Figs. 7-9)Female: Idiosoma oval, length 0.77-0.81 mm, width 0.49-0.58 mm. Dorsal plate bearing 39 pairs of setae, Pilus dentilis expanded in the middle part, and with slightly downcurved tip. Sternal plate with convex anterior margin, with a single peak in the middle part, Sti situated on the anterior margin. Metapodal plate kidney-shaped. Holotype female off Tamiops swinhoei monticolus in October, 1977.Male: Unkown.Haemolaelaps anomalis sp. nov. is quite similar to H. orientalis Teng & pan, 1964, but differs in the shape of pilus dentilis.Holotype (?) and Paratypes 2(?) all deposited in Fujian Research Institute of of Epidemic Diseases.更多还原
