摘要
1965年,Cross以Pygmephorus tarsalis Hirst,1921为模式种建立了拟矮螨属Pseudopygmephorus,目前全世界已知约20种,我国已记载2种(高建荣等,1986、1989)。作者在鉴定上海食用菌蒲螨时,发现该属两个新种,兹记述如下。模式标本保存于上海农学院。文中测量单位为μm。
The present paper describes two new species of the genus Pseudopygmephorus Cross collected from China. The type specimens are d posited in Shanghai Agricultural College.Pseudopygmephorus agurici sp. nov. (figs. 1-12)This new species is similar to P. tarsalis (Hirst, 1921), but it differs from the latter in Ib bifurcate in the female. It is also similar to P. smileyi Hill et Deahl, 1978, but its female can be distinguished from the latter by 2a equal to 2b and the post margin of the first tergum of hysterpodosoma straight. Its male can be separated by the outer margin of tibia Ⅳ having only one solenidium.Holotype (?), 23. Ⅸ. 1985, collected from mushroom compost in Shanghai.Allotype (?), 16. Ⅺ. 1985, on manure, Shanghai.Paratypes: 7(?) 1(?), date, locality same as the allotype. 1$, date and locality same as holotype. 5(?) 1(?), 5. Ⅹ. 1983; 5(?), 26. Ⅸ. 1983; 3(?), 23. Ⅸ. 1985; 14(?), 15. IX. 1984; 8(?), 11. Ⅹ. 1985; 1(?), 4. Ⅹ. 1985; 2(?), 10. Ⅹ. 1984; all collected from mushroom compost in Shanghai. 7(?), 27. VIII. 1984, on the compost which is being pasteurized, Shanghai. 4(?), 26. Ⅸ. 1983, on straws in greenhouse, Shanghai.Pseudopygmephorus shanghaiensis sp. nov. (figs. 13-24)The female of the new species resembles that of P. abdominalis (Berlese, 1904) in having long stigmata, but it may be recognized from the latter by Ib bifurcate. The new species also resembles P. smileyi Hill et Deahl, 1978, but the former has narrow and long stigmata and the normal shape of propodosoma.Holotype (?), allotype (?), and paratypes 24(?) 8(?), 23. Ⅷ. 1984, collected on manure, Shanghai. Paratypes 3(?), 8. Ⅹ. 1984; 5(?), 9. Ⅹ. 1984; 5(?), 15. Ⅸ. 1984; 5(?), 11. Ⅹ. 1985; 2(?), 5. Ⅹ. 1983, all collected from mushroom compost, Shanghai. 1(?), 10. Ⅴ. 1985, from sawdust, Shanghai. 1(?), 10. Ⅴ. 1985, on straw, Sh.nghai.
