Nihonogomphus simillimus Chao,sp.nov. Distribution:Fujian,Guangzhe xian. Measurements(mm.):(?),body length,57;abdomen,42;anal appendages,3.5; hind wing,36. Holotype,(?),Fujian,Guangzhe xian.1980.vi.11.Type No.013.Deposited in the Laboratory of Biological Control of Fujian Agricultural College. The present new species Nihonogomphus simillimus Chao is similar to lief- tincki Chao,bequearti Chao and semanticus Chao in the color pattern of the syn- thorax (fig.3),the general structures of the accessory sexual organs (figs.4,5) and the structure of the caudal anal appendages (figs.1,2).It runs to couplet 6 of the author’s key to the Chinese species of the genus Nihonogomphus (Chao, 1954,Act.Ent.Sin.,4(4):407)in that the labrum is black,with a subapical transverse yellow band.However,it can be differentiated from semanticus in that the anteclypeus and the postclypeus are not entirely black and that the hooked apical narrow portion of the anterior hamulus is smoothly curved(fig. 4)instead of long and straight.It can be differentiated from bequearti in that there is no narrow antehumeral stripe below(fig.3),the labrum is not mainly yellow,the postclypeus is not marked with a pair of small brown spots and the hooked apical narrow portion of the anterior hamulus is not strongly bend- ed.It differs from lieftincki in that the labrum is not entirely black,the postclypeus is not black nor with a pair of large yellow spots confluent with the transverse frontal stripe above,the posterior hamulus is not produced api- cally into a long hook and the laminae of the seminar vescularis of the penis are not produced apically into finger-like processes.
