THREE NEW SPECIES OF CRAMBINAE (LEPIDOPTERA: PYRALIDAE) IN CHINA

Abstract Three new species of Crambinae from China, Eschata truncata Song & Chen, sp. nov., Eschata tricomia Song & Chen, sp. nov., Pseudargyria acuta Song & Chen, sp. nov. and the female of Girdharia tau-tomma Kapur are described, with figures and illustrations of genitalia provided. E. truncata resembles E. smithi Bleszynski, but valva with one short truncated process in costa; E. tricomia differed from all recorded species by valva with a triangular process on dorsum; P. acuta resembles P. marginepunctalis (Hampson), but with cucullus rapidly pointed and aedeagus with one group of comuti. E. bleszynskieila Minet is proposed as a junior synonym of E. shanghaiensis Wang & Sung.

记述了草螟亚科 3新种 :截突大草螟EschatatruncataSong&Chen ,角突大草螟EschatatricorniaSong&Chen和尖端银草螟PseudargyriaacutaSong&Chen。首描述了纵带双突草螟GirdhariataurommaKapur的雌性个体特征。对新种及新描述性别个体的外形和外生殖器进行了描述 ,并给出了其外生殖器特征图。截突大草螟Es chatatruncataSong&Chen的抱器背有一个短而末端平截的突起 ;角突大草螟EschatatricorniaSong&Chen的抱器瓣的背缘有一个三角形的突起 ;尖端银草螟PseudargyriaacutaSong&Chen的抱器端急尖 ,阳茎内有一组角状器。通过对布兰大草螟EschatableszynskiellaMinet的研究 ,认为上海大草螟E .shanghaiensisWang&Sung应为有效名 ,布兰大草螟EschatableszynskiellaMinet为上海大草螟的次级异名。
