【Abstract】 Plastosciara (Spathobdella) auriculae, sp. n. (figs. 1-7)Holotypeo(?), allotype(?), paratypes 1(?), 12 (?) (?), Beijing(Huairou County) 1977-Ⅴ-12, collected on the cultivated Auricularia auricula (L. ex Hook) Underw. by Yang Chi-Kun and Lou Long-hou, and deposited in the Insect Collections of Beijing Agricultural University.Only one species of the genus Plastosciara Berg. in our fauna has been recorded from Taiwan Province,and the subgenus of this species P.cornuta Leng-ersdof (1927)is uncertain. This new species belongs to the genus Spathobde-lla Frey, a subgenus of Plastosciara Tuomikoski (1960) , somewhat allied to the European species P. (S. ) falcata Tuomikoski, but distingushable from it by the male distimere(fig. 4),with one strong apical process obviously shorter, and with four preapical spines set close to one another.更多还原
