The representatives of the enigmatic genus Leptopanorpa MacLachlan are characterized by exaggeratedly elongated male abdomens and are likely endemic to Java and Sumatra, Indonesia. Here, we present a taxonomical revision of 14 species of Leptopanorpa, including two new species: Leptopanorpa linyejiei sp. n. from West Java and Leptopanorpa majapahita sp. n. from East Java. A key to species of Leptopanorpa is provided. Leptopanorpa sieboldi MacLachlan is treated as a junior synonym of Leptopanorpa charpentieri (Burmeister), and Leptopanorpa pi decorata Lieftinck is synonymized with Leptopanorpa pi (van der Weele). Leptopanorpa peterseni Lieftinck is reported from Bali for the first time. In order to unravel the phylogeny of Leptopanorpa and other groups with elongated male abdomens, maximum parsimony and Bayesian inference analyses were performed based on 61 morphological characters and partial sequences of one nuclear gene (28S ribosomal RNA) and two mitochondrial genes (cytochrome c oxidase subunits I and II). Thirty‐three species in Panorpoidea were selected as in‐group taxa and two species in Choristidae as out‐group taxa. The results highly support a monophyletic Leptopanorpa, which nests within a paraphyletic Neopanorpa van der Weele. Both parsimonious and Bayesian results suggest that Leptopanorpa can be divided into four subclades. We elucidated the evolutionary history of Leptopanorpa with regard to the paleogeological events of Sundaland and corroborated the multiple origins of elongated male abdomens in Panorpoidea. We also hypothesized that the ventral hook on the male abdominal sternum VI of L. linyejiei sp. n. is very likely used to control the female's abdomen during copulation.

神秘的蝎蝇属Leptopanorpa MacLachlan(Mecoptera:Panorpidae)的分类学修订和系统发育分析

Leptopanorpa MacLachlan神秘属的代表特征是男性腹部过长,可能是印度尼西亚爪哇和苏门答腊特有的。在这里,我们提出了14个Leptopanorpa物种的分类学修订,包括两个新物种:Leptopanorpa linyejiei sp。。来自西爪哇和Leptopanorpa majapahita sp。。来自东爪哇。提供了Leptopanorpa物种的关键。Leptopanorpa sieboldi MacLachlan被视为Leptopanorpa charpentieri(Burmeister)的初级同义词,而Leptopanorpa pi decorata Lieftinck被称为Leptopanorpa pi。(范德韦勒)。Leptopanorpa peterseni Lieftinck首次从巴厘岛报道。为了揭示Leptopanorpa和其他具有延长男性腹部的群体的系统发育,基于一个核基因(28S核糖体RNA)和两个线粒体基因(细胞色素C氧化酶亚基)的61个形态特征和部分序列,进行了最大简约和贝叶斯推断分析。III)。Panorpoidea中有33种被选为组内类群,而Choristidae中有2种被选为组外类群。结果高度支持一个单Leptopanorpa,一个并系在其中嵌套Neopanorpa范德韦勒。简约和贝叶斯结果都表明,Leptopanorpa可以分为四个子分支。我们阐明了关于苏达兰古地理事件的Leptopanorpa的进化史,并证实了Panorpoidea细长男性腹部的多种起源。我们还假设L. linyejiei sp。的雄性腹部胸骨VI的腹侧钩。。在交配过程中很可能用于控制女性的腹部。
