摘要
1987年7月15—25日,新疆农垦科学院寄生虫病研究室在新疆东部——巴里坤草原进行甲螨垂直分布规律的重点调查,采得一批甲螨,经鉴定发现二新种和一新纪录,记述如下。文内所用量度单位均为微米,所有标本保存于新疆农垦科学院寄生虫病研究室。
This paper describes a new species of Phauloppia, a new species of Multioppia from Balikun Grasslands of Xinjiang, China, and a species of Licnodamaeus as a new record to China. All type specimens are deposited in the Laboratory of Parasitology, Xinjiang Academy of Agricultural Reclamation.Phauloppia xinjiangensis sp. nov. (fig. 1)Holotype (?), No.87-1056, Balikun Grasslands, Xinjiang (43°?39' N, 93°?03' E, 1634m), 1987-Ⅶ-17. Paratypes 3 (?) (?)4 (?) (?), same data as holotype, collected by Zheng Jinghong et al.The new species is similar to phaulo ppia longiporosa Mahunka, 1982 (Hungary ) in the shape of rostrum, all dorsal setae barbed and anterior to notogaster with wrinkles. But it differs from the latter as follows:1) The new species is smaller in size (410-456μm).2) The areae porosae of the new species small and rounded instead of large and semicircular.3) The posterior margin of body appears acuter rather than wave-like.4) Shape of lamellar and sensillum.Multioppia xinjiangensis sp. nov. (fig. 2)Holotype (?), No. 87-1057, Balikun Grasslands, Xinjiang (43°?54' N. 92°?33' E, 1760 m), 1987-Ⅶ-18. Paratypes 3 (?) (?) 11 (?) (?), same data as holotype, collected by Zheng Jinghong et alThis new species resembles M. wilsoni Aoki, 1964, distributed in Japan and China, as well as M. gapsaensis Choi, 1986, ( Korea ), in the shape of ribs on prodosoma, sensillum and rostral seta, but new species is smaller than the other two species. It differs from M, wilsoni in:1) Lyrifisure im located between seta dm and 1m which stand in a row.2) With 13-15 barbs along distal part of sensillum.3) Epimeral seta 3c long, banded and barbed. It differs from M. gapsaeusis in: 1) Notogastral setae of the new species are smooth and short.2) Without costulae on prodosoma.Licnodamaeus pulcherrimus Paoli, 1908,new record (fig. 3)Specimens examined: 2 (?) (?) , 1 (?), Balikun Grasslands, Xin jiang (43° ?39' N., 93°?03' E., 2040 m), 1987-Ⅶ-19. collected by Zheng Jinghong et al.
