项目摘要

1. Collection of the adult cephalciine sawflies was made at Nakayama-toge, Nukabira and Yamda-onsen in Hokkaido from June 17 to 26, 1991, and at Minoto in Yatsugatake Mountains, Nagano Prefecture from August 4 to 9, 1991. Type material of the subfamily housed in the University of Osaka Prefecture and in Kobe University was studied.2. As a result of comparative studies of the adult morphology, the following characters have been found useful for classifying the Cephalciinae : shape and color of the maculation (those on the head and legs, in particular) ; structure of the head (punctuation of the paraantennal field, in particular) ; and configuration of the male genitalia. Presence or absence of pilosity on the costal cell in the forewing was considered important in distinguishing two closely related genera Acantholyda and Cephalcia, but the present study has shown that the character is not stable at the genus level and thus not useful for generic classification.3. Japanese species of the subgenus Itycorsia of the genus Acantholyda were revised. Of the four species of Itycorsia previously recorded from Japan, one ("Acantholyda laricis (Giraud)") has been found misidentified and undescribed, and four additional undescribed or unrecorded species have been recognized in Japan, one of them being described as new under the name of Acantholyda flaviventris(reference no. 1)4. Three species of Cephalciinae collected in Sichuan Province, China, in 1990, and in Taiwan in 1991 were studied and described as new : Cephalcia sichuanica (Sictiuan ; reference no. 2), Acantholyda taiwana and Cephalcia chui (both from Taiwan ; reference no. 3).

1. 1991年6月17日至26日在北海道中山村、内卡比村和山田温泉采集成年头叶锯蝇，1991年8月4日至9日在长野县矢竹山Minoto采集成年头叶锯蝇。研究了大阪府大学和神户大学的亚科类型资料。作为对成虫形态的比较研究的结果，发现下列特征对头蝠科的分类很有用：斑纹的形状和颜色（特别是头部和腿部的斑纹）；头部的结构（尤其是副天线字段的标点符号）；以及男性生殖器的形状。前翅肋细胞上是否有毛囊被认为是区分棘科和头科两个密切相关属的重要因素，但目前的研究表明，该特征在属水平上不稳定，因此对属分类没有帮助。对刺荆属的刺荆亚属的日本种进行了修正。先前在日本记录的四种树蛾中，有一种（“Acantholyda laricis （Giraud）”）被发现被错误地识别和描述，另外四种（“Acantholyda laricis （Giraud）”）在日本被识别出来，其中一种以Acantholyda flaviventris的名义被描述为新物种。1) 4。对1990年在中国四川省和1991年在台湾采集的头虫科3种进行了研究，并作为新种加以描述：头虫科(Cephalcia sichuanica, Sictiuan；2)台湾棘叶和chui头叶(均产自台湾，参考文献号：3)。
