云南和福建的隐头叶甲新种 鞘翅目 肖叶甲科

本文记述隐头叶甲八个新种,分隶于两个属:隐盾叶甲属Adiscus Gistl和接眼叶甲属 Coenobius Suffrian.除一种产于越南外,其余七种都是国产,其中四种采自云南,三种采自福建。模式标本存放在中国科学院动物研究所。 隐头叶甲亚科Cryptocephalinae原隶叶甲科,作者之一于1964年把它分出(见《昆虫学报》13:469-483),和肖叶甲亚科Eumolpinae、隐肢叶甲亚科Lamprosomatinae、瘤叶甲亚科Chlamisinae以及锯角叶甲亚科Clytrinae,组成为一个独立的科,称肖叶甲科Eumolpidae。     

叶甲亚科后翅比较形态学研究

通过对叶甲亚科昆虫20属20种后翅的比较形态学研究,主要对叶甲亚科翅脉名称、翅脉变化类型进行了探讨,给出了叶甲亚科翅脉模式图、20种翅脉的形态特征图和翅脉变化类型图,并对其进化意义进行了初步的总结,认为中国叶甲亚科中最原始的后翅类型应为：长宽比例大,Cu1a与Cu1b之间具cv横脉或Cu1b与Pcu之间具cp横脉以及Cu1b与Pcu端部分开,不融合为一根。     

叶甲科三亚科十三种叶甲酯酶同工酶的研究(鞘翅目,叶甲总科)

应用聚丙烯酰胺凝胶电泳方法分析研究了叶甲科3亚科13种昆虫的酯酶同工酶.结果显示,其聚类结果与传统分类结果基本相一致,说明以酯酶同工酶作为研究手段来进行叶甲类昆虫亚科以下阶元的分类是可行的,同时也说明了它们酯酶同工酶酶谱的差异和其分类地位是一致的;但跳甲亚科和叶甲亚科先聚为一类,再与萤叶甲亚科聚为一类,与前人的研究有差异,作者认为:酯酶同工酶的编码基因可能是快进化单位,在解决亚科以下阶元的系统关系时是很好的分子标记,而对于研究叶甲科、亚科间的系统关系,就不一定很合适.

丝殊角萤叶甲的线粒体基因组测序及系统发育分析

【目的】为探究丝殊角萤叶甲Agetocera filicornis (Laboissiere, 1927)线粒体基因组结构特征及叶甲亚科的系统发育关系。【方法】利用高通量测序方法测定丝殊角萤叶甲线粒体基因组序列。选择叶甲亚科Chrysomelinae和萤叶甲亚科Galerucinae的128个物种作为内群,选择肖叶甲亚科Eumolpinae的3个物种作为外群,利用最大似然法和贝叶斯法重建叶甲亚科的系统发育关系。【结果】丝殊角萤叶甲的线粒体基因组全长为15 814 bp,包含37个基因（13个蛋白质编码基因、2个核糖体RNA基因和22个转运RNA基因）和一段非编码控制区。其线粒体基因组AT含量丰富（76.6%）,并且AT偏斜为正值（0.053）,GC偏斜为负值（﹣0.252）。不同的系统发育分析方法构建的系统发育关系支持萤叶甲亚科为单系群,叶甲亚科为非单系群。【结论】本研究首次获得了丝殊角萤叶甲的线粒体基因组全序列。构建了叶甲亚科的系统发育关系,为更好地理解叶甲亚科、萤叶甲亚科和丝殊角萤叶甲的系统发育提供线粒体基因组数据。     

Function and functional groupings of the complex mouth apparatus of the squat lobsters Munida sarsi Huus and M. tenuimana G.O. Sars (Crustacea: Decapoda).

Like all other decapods, the anomuran squat lobsters Munida sarsi and M. tenuimana have a mouth apparatus composed of six pairs of mouthparts plus labrum and paragnaths (upper and lower lips). To study the functional significance of this complexity, we examined the mouthparts with scanning electron microscopy and also observed their function directly, under laboratory conditions, using macro-video equipment. No differences were found between the two species. The movement patterns of the mouthparts are described in detail and illustrated as serial drawings. Proceeding from maxillipeds 3 towards the mandibles, the movement pattern gets increasingly stereotypical, with the mandibles performing but a single movement in a medio-lateral plane. From morphology, the mouthparts are subdivided into 20 parts, but from the functional analyses the 20 parts form 8 functional groups: 1, transporting mouthparts (maxilliped 2 endopod and maxilliped 3 endopod); 2, transporting-aligning mouthparts (maxilliped 1 basis); 3, sorting-aligning mouthparts (maxilla 1 basis and maxilla 2 basis); 4, current-generating mouthparts (flagella of maxilliped 2 and maxilliped 3 exopods); 5, cutting-crushing mouthparts (incisor and molar processes, labium, and mandibular palp); 6, ingesting mouthparts (maxilla 1 coxa, maxilla 2 coxa, and maxilliped 1 coxa); 7, respiratory mouthparts (scaphognathite, maxilliped 1 epipod, and maxilliped 2 and maxilliped 3 exopods); and 8, dorso-ventral mouthparts (maxilla 1 endopod, maxilla 2 endopod, maxilliped 1 endopod, and maxilliped 1 exopod). These groupings apply mostly to the processes of food handling and have little significance with respect to grooming. When comparing our results to the literature on other decapods, we found much resemblance to conditions in other anomurans.     

Observations on mouthparts of Dermatobia hominis (Linneaus Jr., 1781) (Diptera: Cuterebridae) by scanning electron microscopy

The ultrastructure of the mouthparts of Dermatobia hominis was studied using scanning electron microscopy. The morphological characteristics of the segments, articulations, sensory organs, and pilose covering are described. Mechanoreceptors of the long trichoid sensillum and smaller trichoid sensillum types were observed, as well as labellar gustatory receptors of the basiconic sensillum type, which differed between the sexes. These observations are discussed with reference to the current literature on the morphology and sense organs of dipteran mouthparts, and the prevailing view that the adult mouthparts of this species are non-functional is challenged.     

The genera of Chrysomelinae (Coleoptera: Chrysomelidae) in Costa Rica

Keys in Spanish and English are given for the genera of Chrysomelinae known from Costa Rica. For each genus, a list of species compiled from collections in the University of Costa Rica, the National Biodiversity Institute, and the entomological literature is presented. The genus Planagetes Chevrolat 1843 is recorded for the first time from Central America, and the genus Leptinotarsa St?l 1858 is synonymized with Stilodes Chevrolat 1843.
