This study examines the evolution hindwing shape in Chinese dung beetle species using morphometric and phylogenetic analyses. Previous studies have analyzed the evolution of wing shape within a single or very few species, or by comparing only a few wing traits. No study has analyzed wing shape evolution of a large number of species, or quantitatively compared morphological variation of wings with proposed phylogenetic relationships. This study examines the morphological variation of hindwings based on 19 landmarks, 119 morphological characters, and 81 beetle species. Only one most parsimonious tree (MPT) was found based on 119 wing and body characters. To better understand the possible role of the hindwing in the evolution of Scarabaeinae, additional phylogenetic analyses were proposed based on the only body features (106 characters, wing characters excluded). Two MPT were found based on 106 body characters, and five nodes were collapsed in a strict consensus. There was a strong correlation between the morphometric tree and all phylogenetic trees (r>0.5). Reconstructions of the ancestral wing forms suggest that Scarabaeinae hindwing morphology has not changed substantially over time, but the morphological changes that do occur are focused at the base of the wing. These results suggest that flight has been important since the origin of Scarabaeinae, and that variation in hindwing morphology has been limited by functional constraints. Comparison of metric disparity values and relative evolutionary sequences among Scarabaeinae tribes suggest that the primitive dung beetles had relatively diverse hindwing morphologies, while advanced dung beetles have relatively similar wing morphologies. The strong correlation between the morphometric tree and phylogenetic trees suggest that hindwing features reflect the evolution of whole body morphology and that wing characters are suitable for the phylogenetic analyses. By integrating morphometric and cladistic approaches, this paper sheds new light on the evolution of dung beetle hind wings.  相似文献

对中国锯天牛族的后翅基部关节和后翅翅脉特征进行了研究,发现利用Kukalová-Peck和Lawrence (2004)的后翅命名系统能够很好地对中国锯天牛族后翅翅脉进行命名。但是在中国锯天牛族中,后中脉( MP)和前肘脉(CuA)在后缘并不合并;当前臀脉( AA3)和前肘脉(CuA3 +4)与后肘脉(CuP)相遇时,前臀脉(AA3)消失,前肘脉(CuA3 +4)和后肘脉(CuP)合并,因此楔室(W)仅由肘脉(Cu)的分支脉围成。尽管基部翅关节在研究的各属和各种之间没有表现出差异,但是后翅翅脉在土天牛属Dorysthenes和锯天牛属Prionus不同种类之间差异明显,这些特征包括径室的长宽比例和各边的长度关系、r3存在与否及其长度、后径脉的长度、楔室的长宽比例、以及后中脉(MP3 +4)和前肘脉(CuA3 +4)端部是否分叉等。因此,后翅翅脉特征在土天牛属Dorysthenes和锯天牛属Prionus分种时可能具有分类学意义。  相似文献

本文以翅面正投影形状的特征参数为指标,对20科71种鳞翅目蛾类昆虫进行系统聚类。结果,粘虫Mythimna separata、小地老虎Agrotis ypsilon、稻纵卷叶螟Cnaphalocrocismedinalis等迁飞昆虫集中地归于一类,表明具有远距离迁飞行为的蛾类翅面几何形状相似,存在区别于其它种类的共同特征,即前翅较窄长,翅前缘较平直,外侧宽阔。这可能是适应远距离迁飞的特征。  相似文献

Abstract  Numerical cladistic method was used for analyzing the phylogeny of ladybirds, based upon adult and larval characters. The analysis of adult characters for 21 tribes, representing all subfamilies proposed by various authors, exhibited 18 equally parsimonious cladograms with high level of homoplasy. Five lineages were roughly revealed in the strict consensus tree: Sticholotidinae, Epilachninae, Coccinellinae (including Singhikalini), Coccidulinae (excluding Noviini) and Scymninae+Chilocorinae. The taxonomic interpretation of the adult analysis was similar to the classification proposed by Chazeauet al . (1990). Comparison of a preliminary analysis based on the larval characters for 14 tribes revealed only one component consistently supported in both analyses (Serangiini+Sukunahikonini). Larval analysis showed that Epi-lachinae is the most primitive and highly derived group of the Coccinellidae. Larval characters might be more satisfactory in revealing the phylogeny.  相似文献

根据成虫和幼虫的特征,应用数值支序方法探讨瓢虫科的系统发育.基于中国21族(包括不同学者提出的所有亚科)36个成虫性状,计算得到18个具有高度同质(homoplasy)的最简约的支序图.共同树显示5个支系:小艳瓢虫亚科,食植瓢虫亚科,瓢虫亚科(包括粗毛瓢虫族Singhikalini);红瓢虫亚科(不包括短角瓢虫族),以及小毛瓢虫亚科+盔唇瓢虫亚科(包括短角瓢虫族).这与Chazeau等(1990)提出的分六亚科系统相似.对14族幼虫18个性状初步分析,结果与相同14族成虫分析比较,只有一个组分即刀角瓢虫族和展唇瓢虫族的亲缘关系在两个分析中得到一致的支持.食植瓢虫是瓢虫科中最原始但高度衍化的一族.在揭示系统发育上,幼虫的研究或许更令人满意.  相似文献

The relationships among the genera and tribal groupings of Riodininae with five forewing radial veins, and between these and tribes with four forewing radial veins, were examined using a phylogenetic analysis. Using the type species from all sixteen genera in the tribal groupings Eurybiini, Mesosemiini and incertae sedis (a presumed paraphyletic group of loosely related genera), and representatives from the four forewing radial‐veined riodinine tribes, thirty‐five new and traditional characters were coded from adult ecology, wing venation and pattern, the adult head and body, male and female genitalia, and early stage ecology and morphology. The majority of characters are illustrated. Phylogenetic analysis of these data produced five equally most parsimonious cladograms using equal weights and after successive weighting. The strict consensus of these confirms the monophyly of Eurybiini and Mesosemiini as currently conceived, but also indicates several higher‐level relationships not previously hypothesized. Mesosemiini is here more broadly defined to also include the entire incertae sedis section, and the tribe is divided into Mesosemiina, for the previously delimited Mesosemiini plus Eunogyra and Teratophthalma, and Napaeina, subtr.n. for the incertae sedis section minus these two genera. The following hypothesis of relationships is tentatively proposed for the basal clades of Riodininae: Mesosemiini + (Eurybiini + remainder of Riodininae). These new hypotheses, and the characters supporting them, are discussed and compared with those previously proposed.  相似文献

A phylogeny of the families of Scarabaeoidea (Coleoptera)   总被引:1,自引:1,他引:0  
Abstract. A study, based on examination of thirteen scarabaeoid families, was made of 134 adult and larval characters from the following character suites: 105 adult characters of the antennae, eye, epipharynx, mandible, maxillae, labium, tentorium, trochantin, procoxae, mesocoxae, mesothoracic spiracles, hind wing articulation, hind wing base, hind wing venation, hind wing folding, abdominal sternites, abdominal spiracles, male genitalia, ovarioles and karyotype; twenty larval characters of the antennae, fronto-clypeal suture, stemmata, labial palpi, maxillae, mandibles, legs, stridulatory apparatus, spiracles and ecdysial process; and nine adult and larval biological characters. In order to assess the reliability of different characters in resolving scarabaeoid family relationships, six data sets were subjected to cladistic analysis: the total evidence character set (134 characters), restricted adult character set (thirty-two characters, not including those of the wings), wing character set (seventy-three characters), larval character set (twenty characters), biological character set (nine characters) and re-coded Howden (1982) character set (thirty-nine characters). The complete character set and wing character set both produced phylograms with all nodes resolved; the restricted adult data set, larval data set, Howden (1982) data set and biological data set produced phylograms with diminishing levels of node resolution. The reconstructed phylogeny, from the preferred phylogram of the total evidence character set, shows that the Scarabaeoidea comprises three major lineages; a glaresid, passalid and scarabaeid lineage. The glaresid lineage consists only of the Glaresidae. The passalid lineage comprises two major lines; a glaphyrid line (containing Glaphyridae, Passalidae, Lucanidae, Diphyllostomatidae, Trogidae, Bolboceratidae and Pleocomidae) and a geotrupid line (containing Geotrupidae, Ochodaeidae, Ceratocanthidae and Hybosoridae). The scarabaeid lineage contains those taxa traditionally included within the Scarabaeidae (Aphodiinae, Scarabaeinae, Orphninae, Melolonthinae, Acoma, Chasmatopterinae, Hopliinae, Oncerinae, Rutelinae, Dynastinae, Trichiinae, Cetoniinae and Valginae).  相似文献

Abstract
Three new species of Polistes Latreille are described from Papua New Guinea. Of these, P. occultus sp. n. largely fits the diagnosis of the subgenus Stenopolistes van der Vecht. However, while P. watutus sp. n. and P. medius sp. n. have the jugal lobe of the hind wing defined by a wide incision (an apomorphic character of Stenopolistes ), in the other characters distinguishing Stenopolistes and the subgenus Polistella Ashmead have states typical of Polistella. If Stenopolistes is regarded as a subgenus, then Polistella is defined only by a symplesiomorphy, thus Stenopolistes must be synonymised under Polistella.  相似文献
