摘要
厚厉螨属Pachylaelaps Berles,1888全世界已有40余种,我国迄今报告过4种。本文记述5种厚厉螨,其中西西里厚厉螨Paehylaelaps siculus Berlese,1892为我国首次纪录,其他4种为新种:四联厚厉赌P.quadricombinatus sP.nov.、短毛厚厉螨P.brevisetosus sp.nov、疣足厚厉螭P.turocoxus sp.nov.和方形厚厉螨 P.quadratus sp.nov.。
The present paper deals with 4 new species and 1 new record of the genus Pachylaelaps from China.1. Pachylaelaps siculus Berlese, 1892The first record in China. Specimens: 5 females were collected off 2 beetles of Scara- baeidae on June 24, 1987, from Longchuan County, Yunnan Province.2. Pachylaelaps quadricombinatus sp. nov. (figs. 1-6)Holotype ♀ was collected off Microtus fontis Buchner, on Aug. 8, 1986, from Taibai County (34.1°N, 107.3°E), Shaanxi Province, deposited in Shaanxi Health and Anti-Epidemic Station.This new species resembles Pachylaelaps litteralis Halbert, 1915, but with wider geni'o-ventral plate and slender corniculi, especially metapodal plate with characteristic form.3. Pachylaelaps brevisetosus sp. nov(figs. 7-19)Holotype ♀ and allotype ♂ were collected off beetle of Scarabaeidae, in May 1983, from Binchuan County (26°N, 100.4°E), Yunnan Province, deposited in Guiyang Medical College.This new species is similar to Pachylaelaps furcifer Oudemans, 1903, but differs from the latter species in shorter dorsal setae, female chela only,one tooth, and metapodal plate like a brush, male with a special structure before hypostomal plate, trochanter of leg Ⅲ bearing a spine and femur of leg Ⅲ with a protuberance.4. Pachylaelaps torocoxus sp. nov. (figs. 20-25)Holotype ♀ collected on Sept. 3, 1982, off Rattus flaviffctus Milne-Edwards, from Xian City (34.14°N, 108.95°E), paratypes 2♀♀ collected from Hancheng County (35.5N, 110.5E), one on Sep. 16, 1982, off Mus musculus Linnaeus; another on Sep. 20, 1982, off Apodemus agrarius Pallas, the latter one deposited in the Guiyang Medical College, the other two deposited in the Shaanxi Health and Anti-Epidemic Station.This new species closely near to Pachylaelaps siculus Berlese, 1888, but with wider anterior margin of body, and bearing lesser number of dorsal setae, metapodal plate absent or rudimen-tal, especially a protuberance on the inner side of subapex of coxa I is considered as a diagnostic character.5. Pachylaelaps quadratus sp. nov. (figs. 26-31)Holotype ♀ collected in Sept. 1981, off a beetle of Scarabaeidae, from Qianxi County (27.04°N, 106.04°N), Guizhou Province, deposited in the Guiyang Medical College.This new species near to the former species, but the specific diagnostic character is the rectangular metapodal plate.
