中国奥胸须夜蛾属Oxaenanus Swinhoe研究并记一新种（鳞翅目：裳蛾科：长须夜蛾亚科）

通过解剖Oxaenanus scopigeralis正模标本和同种雌雄外生殖器,发现O.scopigeralis(Moore,1867),sp.rev.&comb.nov.,(模式产地:印度)命名有效,其曾被认为是O.brontesalis(Walker,1858)(模式产地:婆罗洲)的同物异名.张,韩二人2019年发表的云南奥胸须夜蛾O.yunnana(模式产地:云南)应为O.scopigeralis的同物异名.作者在海南省采集到了奥胸须夜蛾属Oxaenanus 1新种海南奥胸须夜蛾Oxaenanus hainana sp.nov.,其与O.scopigeralis近似,但海南奥胸须夜蛾的前后翅亚外缘线更加模糊,抱器端骨化突起更短更细,阳茎端膜也更加复杂多变.     

Macromoth community structure along a 95-year post-harvest chronosequence in managed forests of northwest Washington State (U.S.A.), with comparison to old growth forest communities

1. The effects of timber harvest in the moist coniferous forests of western North America are not well documented for ecologically important arthropods such as moths.
2. We assessed the response of macromoth community structure (abundance, sample size-corrected estimates of species richness and diversity, and overall community composition) to time since deforestation at 20 previously logged sites (1–95 years post-harvest), and compared the macromoth communities at these stands to four old growth stands.
3. As stand age increased following timber harvest, the number of macromoths captured in ultraviolet light traps increased and the relative abundance of dietary generalists declined, but sample size-corrected estimates of species richness and diversity did not vary. Macromoth community composition of the youngest stands (<10 years post-harvest) differed markedly from each other but converged soon thereafter.
4. Macromoth communities at old growth sites featured higher capture rates, lower dominance by dietary generalists, and higher sample size-corrected estimates of species richness and diversity than at previously logged sites. Community composition profiles for old growth sites differed from all previously logged sites, but the differences were subtle except in comparison to the youngest logged sites. None of the 188 species we sampled were old growth specialists.
5. Our results reveal dramatic initial impacts of deforestation on macromoth communities in moist coniferous forests of western North America. Such effects are largely reversed within two decades post-harvest but some effects persist for at least 95-years following logging.
