Abstract

Computerized cladistic analysis was used to (1) develop a hypothesis of phylogenetic relationships among the three species of the well-defined “Megaxylocopa clade” within subgenus Neoxylocopa Michener, of the genus Xylocopa Latreille, and (2) examine relationships between the members of this clade and other species in the subgenus Neoxylocopa. Twenty-four adult morphological characters were scored for the three species in the “Megaxylocopa clade” plus 10 outgroup taxa from subgenus Neoxylocopa Michener. Xylocopa (Xylocopoides) virginica (Linnaeus) was used as a distant outgroup taxon to root the tree. A single most parsimonious tree was recovered by cladistic analysis using the computer software program TNT. The three species of the “Megaxylocopa clade” form a well-supported monophyletic group that is the sister-lineage of another monophyletic group that includes the other 10 species of subgenus Neoxylocopa. Within the “Megaxylocopa clade,” Xylocopa nautlana Cockerell and X. frontalis (Olivier) are sister-species, relative to X. fimbriata Fabricius.

1802年木蜂属“大木蜂支系”的进化关系分析(昆虫亚目:膜翅目:蜂科)

计算机分支分析用于:(1)提出了定义明确的“大木蝗枝”亚属Neoxylocopa Michener和Xylocopa Latreille中的三个物种之间的系统发育关系假设，以及(2)研究了该分支成员与新木蝗亚属其他物种之间的关系。对3种“巨蝗支系”和10个新蝗亚属外群分类群的24个成虫形态特征进行了评分。木本(Xylocopa) (Xylocopoides) virginica (Linnaeus)被用作远缘外群分类群。利用计算机软件TNT进行进化分析，恢复了一棵最简约的树。“Megaxylocopa分支”的三个物种形成了一个得到良好支持的单系群，这是另一个单系群的姐妹谱系，该群包括其他10种Neoxylocopa亚属。在“大木藻枝”中，木藻naautlana Cockerell和X. frontalis (Olivier)是姊妹种，相对于X. fimbriata Fabricius。

期刊介绍： Tropical Zoology is an international zoological journal publishing original papers in the field of systematics, biogeography, phylogeny, ecology and conservation of all terrestrial and aquatic animal Phyla from tropical and subtropical areas. Only papers with new information, high quality and broad interest are considered. Single species description and checklists are not normally accepted. Review papers are welcome. The journal is owned by the Istituto di Ricerca sugli Ecosistemi Terrestri of the Consiglio Nazionale delle Ricerche, Florence, Italy (CNR-IRET) who performs research into the structure and functioning of aquatic and terrestrial ecosystems, focusing in particular on anthropogenic pressure and global change. The knowledge amassed forms the scientific basis for identifying the most appropriate protective and corrective interventions, and provides support for the bodies entrusted with formulating policies for environmental protection and recovery.
