摘要/Abstract

摘要： 记述采自中国山东境内危害欧美杨的厚爪叶蜂属（膜翅目：叶蜂科：突瓣叶蜂亚科）一新种：中华厚爪叶蜂Stauronematus sinicus Liu，Li&Wei。本种与杨厚爪叶蜂S.platycerus（Hartig，1840）（杨扁角叶蜂）近似，二者主要区别特征是：新种后足基节仅基缘黑色；中胸前侧片上部被毛稀疏，下半部具光裸区；锯腹片17节，3-12节缝具刺毛带；1-5锯刃具细小亚基齿，6-17锯刃亚基齿变宽大；锯基腹索踵基角突出；阳茎瓣头叶中位刺突伸向背叶背顶角，腹叶腹缘稍内凹；体长4.5~6.0 mm等。此外，中华厚爪叶蜂与杨厚爪叶蜂、柳厚爪叶蜂的COⅠ序列K2P距离分别为16.0%和15.7%。

Abstract: In this article, a new species, Stauronematus sinicus Liu, Li & Wei, sp. nov., of Nematinae (Hymenoptera:Tenthredinidae) is described, and the species was collected from Shandong, China. The new species is similar to S. platycerus (Hartig, 1840), but can be distinguished from the latter by the following combination characteristics:Only the base margin of the hind coxa is black; the upper part of mesepisternum has sparse pubescent, and the lower half is glabrous; lancet contains 17 annuli, the 3^rd-12^th sutures with dense annular spines, 1^st-5^th serrulae with small distal teeth, and 6^th-17^th serrulae with larger teeth; basal angle of tangium is prominent; penis valve with ventral margin of paravalva is slightly emarginate, valvispina reaches to dorsal apical corner of pseudoceps; body length is 4.5-6.0 mm. The K2P distance of the COⅠsequence between S. sinicus and S. platycerus is 16.0%, and the K2P distance of the COⅠ sequence between S. sinicus and S. saliciphilus is 15.7%.
