【摘要】 <正> 近年来我们结合有关疾病的防治工作,先后在云南省采到葛李恙螨亚属(SubgenusGahrliepia Oudemans,1912)二新种,记述如下。 宽痕葛李恙螨Gahrliepia(Gahrliepia)eurypunctata新种(图1—5) 鉴别特征 本新种与重庆葛李恙螨G.(G.)chungkingensis Jeu et al.,1963较近似,主要区别是:(1)本种须毛式为B-B-NNB,而非B-B-NNN。(2)盾板上的大形痘痕分布广,在感器前后方均有,而并非仅见于感器的后方。(3)背毛33—34根,而非48—49根。更多还原

【Abstract】 The present paper gives descriptions of two new species of chigger mites parasitic on rodents from Yunnan Province. Type specimens are deposited in the Control and Research Institute of Epidemic Diseases of Yunnan Province.Gahrliepia (Gahrliepia) eurypunctata sp. nov. (figs. 1-5)Idiosoma of engorged larvae 523-624×347-428μ. Byes 2+2. Scutum elongate hexagonal in shape, with 2 types of punctae. Scutal setae 8 in number. Sensillae fusiform. Galeal seta nude. Palpal setae B-B-NNB. Palpal claw 3-forked. Dorsal setae 33-34 in number, arranged 2-4-6-6-6(5)-6-2(3)-2(l). Ventral setae 46-58 in number. Measurements: see Chinese text.Holotype and 7 paratypes, larvae, ex Rattus niviventer confucianus, from Suijiang County, Yunnan, Ⅸ, 1973.This new species is close to G. (G.) Chungkingensis Jeu et al., 1963, but differs from it in: (1) palpal setae B-B-NNB, not B-B-NNN, (2) big punctae in anterior and behind of SB, not only in behind of SB of scutum, (3) dorsal setae 33-34, not 48-49 in number.Gahrliepia (Gahrliepia) linguipelta sp. nov. (figs. 6-10)Idiosoma of engorged larvae 359-406×277-330 μ. Eyes 2+2. Scutum lingulate in shape. Scutal surface with fine punctations. Scutal setae 26-30 in number. Sensillae fusiform. Galeal seta nude. Palpal setae B-B-NNN. Palpal claw 3-forked. Dorsal setae 52-66 in number, arranged (Holotype) 4-3-5-6-13-7-7-6-4-2 = 57. Ventral setae 71-82 in number. Measurements: see Chinese text.Holotype and 9 paratypes, larvae, ex Sciurotamius forresti, Apodemus sylvaticus orestes, Dremomys pernyi and Eothenomys miletus, from Jianchuan County, Yunnan, 12 V, 1975.This new species is close to G. (G.) myriosetosa Wang, 1964 but differs in: (1) humeral setae two pairs, not one pair, (2) sensillae smaller than twice as long as broad, not greater than four times. It is also close to G. (G.) megascuta Hsu et al., 1965, but differs from which in the shape and dimensions of scutum and number of dorsal setae.更多还原
