摘要

根据墨西哥和阿根廷的标本，描述了Rasahus Amyot &； Serville, 1843， R. ellipticus sp. nov.一新种。文中还比较了该新种与近缘种r.b iguttatus （Say, 1832）和r.a hamatus （Fabricius, 1781）的形态特征，并对三种的习性和雄性生殖器进行了说明。Rasahus bifurcatus Champion， 1899最初是根据亚大翅目标本进行描述的，本研究首次报道了该物种的大翅目雄性。Rasahus sipolisii Fallou， 1887年。1892年Bergroth与R. hamatus同义的stat.被确认为有效种，R. angulatus Coscarón, 1986 syn11 .应作为其低级同义种。指定了Lestomerus varies Fallou， 1891年，Pirates concisus Walker， 1873年，R. bifurcatus Champion， 1899年和R. sipolisii Fallou， 1887年的选种。

Description of Rasahus ellipticus sp. nov., with a taxonomic assessment of R. bifurcatus Champion, 1899 and R. sipolisii Fallou, 1887 reinst. stat. (Hemiptera: Reduviidae)

A new assassin bug species in the genus Rasahus Amyot & Serville, 1843, R. ellipticus sp. nov., is described based on specimens from Mexico and Argentina. Morphological comparations between the new species and its related species, R. biguttatus (Say, 1832) and R. hamatus (Fabricius, 1781) are provided together with illustrations of habitus and male genitalia of all three species. Rasahus bifurcatus Champion, 1899 was described initially based on submacropterous specimens, and the macropterous male of this species is reported for the first time in the present study. Rasahus sipolisii Fallou, 1887 reinst. stat., which was synonymized with R. hamatus by Bergroth in 1892, is confirmed to be a valid species, and R. angulatus Coscarón, 1986 syn. nov. should be treated as its junior synonym. Lectotypes of Lestomerus varipes Fallou, 1891, Pirates concisus Walker, 1873, R. bifurcatus Champion, 1899 and R. sipolisii Fallou, 1887 are designated.

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.
