中国大陆单羽蛾科Macropiratidae记述（鳞翅目：羽蛾总科）

单羽蛾科是鳞翅目中非常小的科，目前已记录的昆虫仅有3种，分布于中国（台湾），日本，斯里兰卡，斐济和马达加斯加。首次记述了该科在我国大陆的分布，并首次对东方单羽蛾Agdistopis sinhala (Fletcher, 1909) 的雌性进行了描述。东方单羽蛾Agdistopis sinhala (Fletcher, 1909) 翅展31.0 mm。触角背面灰黄色，少毛，腹面灰色，密被短而细的纤毛；下唇须长于复眼直径的2倍；前翅外缘线白色，近前缘4/5处具1不规则的黑灰色斑；翅面具1从顶角延伸至翅面2/3处的白色窄带。雄性外生殖器爪形突宽大；抱器瓣对称，腹基角具1小钩状突；抱器端部二分叶，形成二棒状突；基腹弧延伸成1近三角形的大突起。雌性外生殖器交配孔大而不规则；导管端片不规则球形，基部的右侧弧形内凹；交配囊卵形；具1对小型囊突。     

中国异斑夜蛾属记述及一新记录种（鳞翅目：夜蛾总科）

记述采自华南地区夜蛾科的异斑夜蛾属Heterospila 1新记录种:异斑夜蛾H.nigripalpis(Walker,1869),提供了该种翅脉以及雄性成虫与外生殖器图片。     

基于线粒体ND1和16S rRNA基因序列探讨中国蝴蝶12科的系统发育关系(鳞翅目: 双孔次亚目: 蝶类)

对中国12科共32种代表蝶类的ND1基因和16S rRNA 基因进行了序列测定（包括新测30种ND1基因和9种16S rRNA基因）和比较分析, 同时采用邻接法、最大似然法和贝叶斯法构建了12科蝶类的系统发育树, 探讨了其高级分类群的系统发育关系。序列分析的结果显示: 经比对处理后的两个基因总长度为869 bp, 其中保守位点373个, 可变位点496个, 简约信息位点375个; A+T的平均含量为80.2％, 明显高于C+G的平均含量19.8％。分子系统树表明: 蛱蝶科不是单系群; 珍蝶类、斑蝶类和喙蝶类位于蛱蝶科内; 粉蝶科和凤蝶科具有共同祖先。据此建议: 绢蝶科应归入凤蝶科; 蚬蝶科归入灰蝶科; 珍蝶类、斑蝶类和喙蝶类作为蛱蝶科中的亚科, 眼蝶类从蛱蝶科中分离出来独立成科。另外, 环蝶类的系统分类地位还有待于进一步研究。     

中国白条小卷蛾属一新种记述（鳞翅目：卷蛾科：新小卷蛾亚科）

记述采自中国海南及台湾的白条小卷蛾属Dudua Walker 1新种,即平截白条小卷蛾D.trunciformis sp.nov.。该种与分布于印度尼西亚的D.brachytoma Diakonoff相似,但其雄性外生殖器抱器瓣末端的腹角圆钝,阳茎长度仅略大于宽度的2倍,具短刺状角状器;而后者抱器瓣末端的腹角角状,阳茎长度约为宽度的3倍,无角状器。     

中国片尺蛾属分类订正并记三新纪录种(鳞翅目：尺蛾科：灰尺蛾亚科)

记录中国分布的片尺蛾属6种,并记述中国3新纪录种：黑片尺蛾Fascellina porphyreofusa Hampson, 1895; F. inornata Warren, 1893; F. rectimarginata Warren, 1894。文中提供了属种描述和鉴别特征,给出了种检索表及成虫和外生殖器图。     

Identifying two moth species (Lepidoptera: Ditrysia) from Saudi Arabia using mitochondrial 16S rRNA sequences

The mitochondrial genetic markers are considered useful tools for discrimination between more closely related lepidopteran taxa. Therefore, the present study aimed to investigate the role of mitochondrial (mt) 16 s rRNA gene in the determination of the taxonomic position for two moth species within Ditrysia clade. Maximum likelihood analysis has indicated a well-supported dendrogram based on the Tamura-Nei model for the recovered lepidopterans. The mt 16 s rRNA query sequences from 24 species within seven families were analyzed. This analysis and bootstrap confidence revealed two major clades representing Glossata suborder within Lepidoptera, with a close relationship of Noctuoidea + (Pyraloidea (Hesperioidea + Papilionoidea)). The subfamily Heliothinae forming a sister group with Risobinae (Noctinae + Hadeninae). In addition, there is a clear observation about the close relation between Phycitinae + Galleriinae within Pyraloidea and Cyrestinae + Limenitidinae within Papilionoidea. The present study supported that the Helicoverpa and Meroptera species are the first accounts of these genera inhabiting Saudi Arabia.     

Little-known accessory glands in female Zygaena moths (Lepidoptera, Zygaenidae)

In the female genital system of Zygaena moths, an additional pair of accessory glands is present besides the Y-shaped sebaceous gland. The term 'Petersen's glands' is proposed for these organs. Anatomy, histology, histochemistry and cytology of Petersen's glands of Zygaena trifolii are described. The sac-like glands, situated in the extreme dorsocaudal part of the abdomen, can be divided into a purely secretory part consisting of acini with large pear-shaped gland cells and a reservoir part with combined secretory and storage function. The secretory cells of the acini are penetrated by long curved ductules or secretory end apparatuses having feltwork consisting of very fine filaments. The cytoplasm is characterized by abundance of smooth tubular endoplasmic reticulum (ATER) and the presence of peroxisomes. This cytoplasmic organization is in accordance with the chemical composition of the sticky secretion, which evidently consists completely of lipids. The ultrastructure of the epithelium lining the reservoir of the glands has both traits of secretory and of transporting epithelia. Besides contributing to the secretion, it may be involved in absorption of residual aqueous phase from the contents of the reservoir.
