化石直脉蝎蛉科再分类(长翅目)

本文对化石直脉蝎蛉科(Orthophlebiidae)的分属做了再分类,仍保留该科内的 2个属:直脉蝎蛉属 Orthophlebia和原直脉蝎蛉属Protorthophlebia,解体中蝎蛉属Mesopanorpa。中蝎蛉属被解体后,其包含所有的种,如Rs1主干带3支或3支以上支脉,归入直脉蝎蛉属;如Rs1仅带2支支脉,归入原直脉蝎蛉属;原中蝎蛉属以Rs主干两倍长于MA主干作为属的分类根据,但这一属征常常导致分类上的混乱,故本文不作为属或亚属的分类根据。上述保留的2个属,再以Rs分支先于、后于或等于MA的特征,即Rs主干短于、长于或等于MA主干作为亚属的分类根据。以此,在直脉蝎蛉属Orthophlebia和原直脉蝎蛉属Protorthophlebia之下各自设立3个亚属(Hong et Zhang, 2004)。在已建立的6个亚属中,Orthophlebia(Brachyphlebia)Hong et Zhang, 2004和Protorthophlebia(Mecynophlebia)Hong et Zhang,2004分别修改为Orthophlebia(Orthophlebia)Westwood, 1845和Protorthophlebia(Protorthophlebia)Tillyard,1933的新异名。中生代直脉蝎蛉中脉的前支(MA)并非在古生代之后就完全消失。根据对中生代不同时期、不同层位、不同地区直脉蝎蛉和本目其他科在内化石标本的观察,中脉及其前、后支脉(MA、MP)仍然继续存在与发展。基于这种事实,本文认为直脉蝎蛉科脉序命名中沿用已久的Rs后支(Rs3 4)应为中脉的前支(MA),原来沿用的中脉(M)为中脉的后支(MP)。这样,有助于我们对长翅目中脉及其前、后(MA、MP)支脉的准确辨认,尤其是对MA脉在地史上变革、发展,以及与Rs脉的演化关系的认识可能有所裨益。

Five new species of Dicerapanorpa Zhong & Hua (Mecoptera,Panorpidae) from Yunnan,China

Five new scorpionfly species of the genus Dicerapanorpa Zhong and Hua, 2013 are described and illustrated from Yunnan Province, China. Dicerapanorpa macula sp. n. can be readily recognized by all branches of paramere parallel, basal and mesal branches extending well beyond basal process of gonostylus in male, and posterior arm of medigynium short and stout in female. Dicerapanorpa deqenensis sp. n. is characterized by basal branch of paramere as long as lateral branch and ventral valve of aedeagus nearly reaching apex of gonocoxite in male, and medigynium with paired auricular lateral processes in female. Dicerapanorpa tanae sp. n. is unique by genital bulb broad and spherical, basal branch of paramere short, and lateral branches curved convergently and parallel apically in male, and main plate of medigynium rounded in female. Dicerapanorpa tenuis sp. n. is distinguishable by hypovalve with largely expanded and inward curved apex and all branches of paramere reaching or exceeding apex of gonocoxite in male, and medigynium slender in female. Dicerapanorpa zhongdianensis sp. n. is characterized by basal branches of paramere parallel and mesal branches curved convergently in male, and main plate of medigynium subtriangular with a pair of auricular lateral processes in female. The species number of Dicerapanorpa is increased to thirteen.LSID: www.zoobank.org/urn:lsid:zoobank.org:pub:A4490511-C475-4C5B-9E89-4BF4EBAA2137     

Two new species of Panorpa (Mecoptera,Panorpidae) from the Hengduan Mountains in Yunnan,China

Two new species of the genus Panorpa Linnaeus, 1758 are described from the Hengduan Mountains in Yunnan, China. Panorpa diqingensis sp. n. can be distinguished from its congeners by vertex dark brown, and occiput yellow; pleura dark brown; gonocoxites bearing a cluster of stout black setae on inner apex; parameres S-shaped in male genitalia. Panorpa dispergens sp. n. can be readily differentiated from other Panorpa species by apical band with a hyaline spot in wings; gonocoxites with a cluster of stout dark brown setae and 3–5 long setae on inner apex; female medigynium with a pair of basal plates. The number of Panorpa species in Yunnan is raised to six. A key to Yunnan species of Panorpa is presented.     

Megapanorpa,a new genus with a single anal horn in males from Oriental China (Mecoptera: Panorpidae)

A new genus of Panorpidae, Megapanorpa gen. nov. , is erected for five new species, Megapanorpa grandis sp. nov. (type species), M. absens sp. nov. , M. gaokaii sp. nov. , M. jiangorum sp. nov. and M. wanghongjiani sp. nov. This genus is similar to Cerapanorpa Gao et al., 2016 in a single anal horn on the sixth tergum of male, but can be differentiated from the latter by the following characters: the seventh abdominal segment of male is constricted and stalk‐like at base, the subgenital plate of female with a pair of lateral plates, and the medigynium of female with a concealed axis. Keys to genera of Panorpidae and species of Megapanorpa gen. nov. are presented. The morphology and function of anal horns in different genera and species have been discussed.

Evolutionary history of the scorpionfly Dicerapanorpa magna (Mecoptera,Panorpidae)

Climate changes can have fundamental impacts on the distributional patterns of montane species, and range shifts frequently lead to allopatric divergence followed by the establishment of secondary contact zones. Many European and North American organisms have retreated to southern refugia during glacial periods and colonized northward during postglacial periods, but little is known about the evolutionary response of cold‐adapted insects to Pleistocene climate changes in eastern Asia. The scorpionfly Dicerapanorpa magna (Chou), with cold temperate habitat preference and weak dispersal ability, provides a good model system to explore how climate changes have influenced the distribution and divergence of cold‐adapted insects in eastern Asia. This study reconstructed the demographic dynamics and evolutionary history of D. magna with phylogeographic approaches, and predicted the species’ suitable areas under the Last Glacial Maximum (LGM) and current scenarios with the ecological niche modelling analysis. The mitochondrial cytochrome c oxidase subunit I resolved three phylogenetic lineages in D. magna dating back to Pleistocene, corresponding well with the geographically isolated Qinling, Bashan and Minshan Mountains. The ecological niche modelling recovered the suitable habitats for D. magna were the Qinling and Bashan Mountains under LGM and current conditions. The three lineages of D. magna might be in a process of incipient speciation, and likely derived their current distribution from separate glacial origins, followed by vicariance and divergence.
