Abstract

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%.
