The morphology of the acrophallus, the distal portion of the male phallus carrying the phallotreme, was studied in 72 exemplar species representing 56 genera and subgenera of the flesh fly subfamily Sarcophaginae. For 42 of those species, scanning electron microscopy was used to clarify the phallic morphology. Terms used to describe the male genitalia were updated based on new interpretations of homology. Male genitalic characters, combined with other morphological characters of adult males and females and of larvae, were used to construct a phylogeny. The monophyly of the subfamily was supported, and some generic‐level sister‐group relationships proposed in the literature, but without previous cladistic analyses, were also supported. The genus Blaesoxipha Loew, as currently recognized, was not monophyletic in our analysis. The genus Helicobia Coquillett is synonymized with Sarcophaga Meigen syn. nov. and treated as a subgenus of the latter. The Sarcophaga subgenera Neobellieria Blanchard and Mehria Enderlein were not monophyletic. Many of the clades in the analysis were supported primarily or exclusively by male genitalic character states, highlighting the importance of the male genitalia as a source of morphological characters for sarcophagine phylogeny. © 2010 The Linnean Society of London, Zoological Journal of the Linnean Society, 2010, 158 , 740–778. 相似文献

The genus Labulla Simon is circumscribed in phylogenetic terms to include the species Labulla thoracica (Wider), L. flahaulti Simon and L. machadoi sp. nov. The genital anatomy of the genus is described in detail and the taxonomy of the genus is reviewed. The monophyly of Labulla is supported by numerous morphological apomorphies of the male palp and female epigynum. Based on a cladistic analysis, a new genus, Pecado gen. nov. , is erected to place Labulla impudica Denis, from Northern Africa. Lepthyphantes insularis Saito and ' Labulla ' nepula Tikader, both formerly included in Labulla , are not congeneric with the type species of Labulla . © 2005 The Linnean Society of London, Zoological Journal of the Linnean Society , 2005, 143 , 359–404. 相似文献

【目的】为丰富赤眼蜂Trichogramma的种类资源,明确野外新采集的一种赤眼蜂的种类,探明该赤眼蜂所感染Wolbachia的类型。【方法】采用挂米蛾Corcyra cephalonica卵卡法在华南农业大学树木园诱集到两批赤眼蜂,通过形态鉴定和PCR扩增ITS2序列并测序分析的分子鉴定手段对野外采集的赤眼蜂材料进行种类鉴定;通过PCR扩增Wolbachia的外膜蛋白基因(wsp)序列,检测赤眼蜂体内Wolbachia的感染情况;通过PCR扩增wsp序列和多位点序列分型(multilocus sequence typing, MLST)对检测到的赤眼蜂体内的Wolbachia进行同源性分析。【结果】所诱集到的两批赤眼蜂均被鉴定为安荔赤眼蜂Trichogramma oleae Voegelé & Pointel,体内Wolbachia的感染率达100%。该Wolbachia株系与安荔赤眼蜂(前南斯拉夫品系)、短管赤眼蜂T. pretiosum(乌拉圭品系)以及T. deion(荷兰品系)体内Wolbachia亲缘关系较近,属于B超组Sib亚组,对应MLST序列型为ST486。【结论】安荔赤眼蜂T. oleae为中国野外首次发现,是完全感染Wolbachia的产雌孤雌生殖品系。本研究为害虫生物防治提供了一种新的天敌种类资源,并为进一步探明Wolbachia与赤眼蜂的互作提供了研究材料。 相似文献

柑橘大实蝇Bactrocera minax(Enderlein),是柑橘的重要害虫。本研究基于光学、扫描电镜、X射线CT,对其雄虫外生殖器的形态结构、阳茎长度和雌虫泄殖腔到受精囊的长度、以及雌雄虫交配过程中的夹持状态和雄虫阳茎冠到达雌虫阴道位置的观察和测量。结果表明,柑橘大实蝇雄性外生殖器是由阳茎(阳茎管和阳茎冠)、生殖突(阳茎内突和生殖环)和抱握器(背刺突和抱器)这3个部分组成。阳茎管是长而弯曲的双套管结构(向腹面卷曲),外管即阳茎管,内含1条输精管(内管),阳茎管腹面褶皱,骨化程度低,背面平坦(中间有沟),骨化程度较高,既可以弯曲折叠又可以变直。休息时,阳茎蜷曲,大部分隐藏在第5腹节内。阳茎冠由生殖杆、阳茎冠体(基囊、喇叭口、裂口和骨化体)组成,精子出口位于阳茎冠顶部喇叭口内和基囊前端的阳茎冠体上的裂口内。成虫交配时,雄虫抱握器夹持住雌虫产卵针背片端部,阳茎能够到达的最远处为雌虫布氏交配囊。雌虫从泄殖腔口至受精囊长度(21.64 ± 0.59 mm)远大于雄虫阳茎的长度(9.21 ± 0.25 mm),表明雄虫的阳茎不能到达雌虫的受精囊,雌性可以通过控制精子是否进入受精囊来控制受精。因此,雌成虫拥有最终的授精控制权。这些结构或组织经过进化,从而适应其阳茎的运动、交配等行为活动。为理解昆虫繁殖生理、进化和多样性,昆虫交配、阳茎运动等行为机制提供理论基础。 相似文献

运用扫描电镜观察了虎凤蝶属现有4种雄成虫的外生殖器。结果表明:中华虎凤蝶Lueh-dorfia chinensis Leech 、长尾虎凤蝶L. longicaudata Lee、乌苏里虎凤蝶L. puziloi Erschoff和日本虎凤蝶L. japonica Leech雄性外生殖器的一般形态结构相似,而其抱器、钩状突、阳茎、阳茎轭片的超微结构存在着差异,这些特征可作为鉴定的依据。通过对雄性外生殖器形态结构的比较,以及有关结构参数的聚类分析,讨论了4种虎凤蝶的亲缘关系。作者认为,中华虎凤蝶具有最原始的结构特征,可能较接近该属祖先,长尾虎凤蝶则与其较近缘;乌苏里虎凤蝶与日本虎凤蝶相对较近缘,与前两种差异略大。 相似文献

A phylogenetic analysis of the orb-weaving spider family Araneidae (Arachnida, Araneae) 总被引:6,自引:0,他引:6

We present the first cladistic analysis focused at the tribal and subfamily level of the orb-weaving spider family Araneidae. The data matrix of 82 characters scored for 57 arancid genera of 6 subfamilies and 19 tribes (and 13 genera from 8 outgroup families) resulted in 16 slightly different, most parsimonious trees. Successive weighting corroborated 62 of the 66 informative nodes on these cladograms; one is recommended as the 'working' araneid phylogcny. The sister group of Araneidae is all other Araneoidea. Araneidae comprises two major clades: the subfamily Araneinae, and the 'argiopoid' clade, which includes all other subfamilies and most tribes (((Gasteracanthinae, Caerostreae), (((Micratheninae, Xylcthreae), Eruyosaccus ), (Eurycorminae, Arciinae)), Cyrlarachninae), ((Argiopinae, Cyrtophorinae), Arachnureae)). Cyrtarachneae and Mastophoreae are united in a new subfamily, Cyr-tarachninae. The spiny orb-weavers alone (Gasteracanthinae and Micratheninae) are not monophyletic. The mimetid subfamily Arciinae and the 'tetragnathid' genus Zygiella are araneids, but .Nephila (and other tetragnathids) are not. On the preferred tree, web decorations (stabilimenta) evolved 9 times within 15 genera, and were lost once. The use of silk to subdue prey evolved once in cribellate and four times in ecribillate orb weavers. Sexual size dimorphism evolved once in nephilines, twice in araneids, and reverted to monomorphism five times. Evolution in other genitalic and somatic characters is also assessed; behavioral and spinneret features arc most consistent (male genitalia, leg and prosomal features least consistent) on the phylogeny. 相似文献

The schizomid genus Mayazomus Reddell & Cockendolpher, 1995, endemic to south‐eastern Mexico, currently comprises seven species. It was originally proposed to accommodate two species, from Chiapas and Tabasco. Recently, five additional species from Chiapas were described. The monophyly of the genus has never been tested using cladistic analysis. We undertook a phylogenetic analysis using the seven described species of Mayazomus as the ingroup, ten exemplar species representing the most similar New World hubbardiids as the outgroup, and one protoschizomid species to root the tree. The analysis was based on 130 morphological characters (continuous and discrete characters). The resulting topologies recovered Mayazomus as paraphyletic, with Heteronochrus estor Armas & Viquez, 2010, from Guatemala nested within the genus; therefore, we formally propose its synonymy herein. Mayazomus appears to be most closely related to Rowlandius Reddell & Cokendolpher, 1995, a South American genus. This contribution also provides new characters derived from the pedipalp setae with important phylogenetic information; as well as the implementation of morphometric ratios, as continuous characters, to partially codify the shape of the male flagellum. The relationships recovered amongst the outgroups used in this contribution are a reliable baseline for future analyses of the phylogeny of the New World schizomids. 相似文献

蓟马科Thripidae昆虫是重要的经济害虫之一,到目前为止,我国蓟马科的分类还比较混乱,亟需对其系统分类进行深入研究。本文基于西北农林科技大学昆虫博物馆(NWAFU)、中国科学院动物研究所(IZCAS)和华南农业大学资源与环境学院(SCAU)检视的实证标本,运用支序系统学的方法对中国蓟马科59属的系统发育进行了初步研究,并探讨了科内的系统发育关系。结果显示:蓟马科是一个单系群,但蓟马亚科Thripinae不是一个单系群;棍蓟马亚科Dendrothripinae和针蓟马亚科Panchaetothripinae亲缘关系较近,且互为姐妹群;绢蓟马亚科Sericothripinae的分类地位应降一级,作为蓟马亚科内的一个族或一个属团;针蓟马族Panchaetothripini的分类地位还有待进一步研究。 相似文献

鹅观草属的系统发育分析 总被引:2,自引:0,他引:2
根据分支系统学的原理和方法, 对禾本科鹅观草属进行了系统发育分析。鹅观草属传统分类上的18 个系被确定为终端类群, 来自形态学、解剖学、细胞学和孢粉学的23 个性状被选作建立矩阵的依据;雀麦族中的短柄草属作为外类群被用于外部性状的极性识别, 过去分析过的性状资料被用于微观特征的极性判断;采用PAUP 程序对矩阵进行运算, 共获得6 个同等简约的谱系分支图, 其中具最低f-比值的图被选作分支分析的基础。结果表明, 分支图上显示的组、系划分与传统分类的基本一致, 各类群间的演化关系与过去凭借单一证据所作的零散推断也基本吻合。所不同的是半颖组各支类群不是共祖起源, 可能具有复杂的内部组成;在个别系间, 分支图展现的类群位置与宏观分析的存在差异。 相似文献
