Abstract

Dolichozelia gen. nov. and its type species Dolichozelia caete gen. et sp. nov. from the subfamily Dexiinae are described from São Paulo (Brazil). The description of Neozelia alini Guimarães, 1975 was the last description of a new genus of Neotropical Dexiini; and after almost 50 years, the description of Dolichozelia gen. nov. constitutes the first new genus of Dexiini from the Neotropical region since Guimarães’ contribution. Prior to this study, 64 genera of Dexiini were known from the Neotropics, the larger tribe of Dexiinae. Herein, a diagnostic key for the Zelia group of genera is given, with the inclusion of Dolichozelia gen. nov. In addition, a brief systematic discussion on dexiines is given in order to further discuss the systematic position of Dolichozelia gen. nov. in the tribe Dexiini. The new genus can be easily distinguished from the other genera in the tribe, mainly by the following combination of characters: legs very elongate, about 3× the length of the abdomen; abdomen about 3× the length of the thorax; syntergite 1 + 2 with a pair of marginal median setae and tergite 3 with two to three equal sized pairs of discal setae; tergite 5 elongate, ending in conical structure. Finally, a description and illustration of the male terminalia is provided for the new genus and species.

巴西大蚊属一新属(双翅目:大蚊科)

摘要报道了巴西圣保罗地区德喜蝇亚科的蠓蠓(Dolichozelia gen. 11 .)及其模式种蠓(Dolichozelia caete gen. et sp. 11)。1975年对Neozelia alini guimar es的描述是新热带德西尼新属的最后一次描述;在近50年的时间里，对Dolichozelia gen. 11 .的描述构成了自guimar斯贡献以来新热带地区的第一个新属。在这项研究之前，在新热带地区已知的德克西尼属有64属，德克西尼属是德克西尼科的一个更大的部落。本文给出了Zelia属群的诊断关键，并将其纳入了Dolichozelia gen. 11 .，并对其dexiines进行了简要的系统讨论，以进一步探讨Dolichozelia gen. 11在Dexiini族中的系统地位。新属可以很容易地与部落中的其他属区分开来，主要是通过以下特征组合:腿很长，约为腹部长度的3倍;腹部约为胸腔长度的3倍;共辉体1 + 2具一对边缘正中刚毛和共辉体3具二到三对等大小的盘状刚毛;辉晶5拉长，末端为圆锥形结构。最后，对新属和新种的雄性终末物进行了描述和说明。

期刊介绍： Austral Entomology is a scientific journal of entomology for the Southern Hemisphere. It publishes Original Articles that are peer-reviewed research papers from the study of the behaviour, biology, biosystematics, conservation biology, ecology, evolution, forensic and medical entomology, molecular biology, public health, urban entomology, physiology and the use and control of insects, arachnids and myriapods. The journal also publishes Reviews on research and theory or commentaries on current areas of research, innovation or rapid development likely to be of broad interest – these may be submitted or invited. Book Reviews will also be considered provided the works are of global significance. Manuscripts from authors in the Northern Hemisphere are encouraged provided that the research has relevance to or broad readership within the Southern Hemisphere. All submissions are peer-reviewed by at least two referees expert in the field of the submitted paper. Special issues are encouraged; please contact the Chief Editor for further information.
