东北与华北大黑鳃金龟分类地位的研究（鞘翅目：鳃角金龟科）

采用RAPD技术和杂交方法对东北大黑鳃金龟（Holotrichia diomphalia Bates1888)和华北大黑鳃金龟（H.oblita(Faldermann1935)的分类地位进行了研究。作者应用40条引物,采用UPDGA法对华北大黑的南京和文登种群。东北大黑的沈阳种群。以及其外群矮臀鳃金龟（H.ernesti Reitter)进行了RAPD分析。所建立的系统发育树显示,东北大黑具有与华北大黑两个地理种群相同的分类地位。同时,作者对两种金龟甲进行了正反交的杂交试验。试验共得到21头正交F1代成虫,3头反交F1代成虫,F1代生活正常,采用东北大黑与F1代回交的方法研究F1代的可育性,2001年6月10日的检查结果显示,四个处理均得到大量回交杂种一龄幼虫和少量二龄幼虫,F1代的雌雄虫均具有正常的生殖力。以上结果表明;两种金龟的次异名。为无效名。

First phylogenetic analysis of the subfamily Pachydeminae (Coleoptera,Scarabaeoidea, Melolonthidae): the Palearctic Pachydeminae*

This paper presents the first phylogenetic analysis of Pachydeminae Reitter, 1902 ; one of the least known subfamilies of Melolonthidae, `leaf‐chafers' (Scarabaeoidea, Coleoptera). Some species of Pachydeminae have recently become agricultural pests in southern Spain. We analysed the phylogenetic relationships among 49 species belonging to 16 genera in the Palearctic region, based on a set of 63 morphological characters from the adult external morphology, wing anatomy, mouthparts and male and female genitalia. The last three sets of characters are described here for the first time. The phylogeny shows that the Palearctic Pachydeminae are monophyletic within the subfamily. Mouthparts and male and female genitalia provide the best synapomorphies for intergeneric relationships. In contrast, most of the external morphological characters used in the taxonomy of Pachydeminae are highly homoplastic. The phylogeny shows a basal split between the genera Hemictenius Reitter, 1897; Pachydema Castelnau, 1832, and the monospecific Peritryssus Reitter, 1918; and a second clade including the rest of genera. The remarkable Peritryssus is confirmed as a Pachydeminae, being the sister group to the monophyletic Hemictenius . Except for the position of P. rubripennis (Lucas, 1848) and P. zhora Normand, 1951, the phylogeny supports the monophyly of Pachydema but rejects the traditional division into species groups and the monophyly of the endemic Canarian species. In contrast, Tanyproctus Faldermann, 1835, must be rejected as polyphyletic. Otoclinius Brenske, 1896, is also probably polyphyletic (two new species synonymies), whereas Leptochristina Baraud and Branco, 1991 , is either mono‐ or paraphyletic. The two Mediterranean genera Ceramida Baraud, 1897, and Elaphocera Gené, 1836, form a monophyletic group, this clade being the best supported by the data set. Ceramida is clearly monophyletic, whereas Elaphocera is probably monophyletic except for E. barbara Rambur, 1843, which shares with Ceramida the character state for numerous mouthpart and genitalic characters. The phylogeny questions the generic status of the small and monospecific genera of Pachydeminae. The monotypic Alaia Petrovitz, 1980 , and Brenskiella Berg, 1898, are merged with Europtron Marseul, 1867, into one clade, whereas Atanyproctus Petrovitz, 1954, is grouped with some species of Tanyproctus , and the monotypic Pachydemocera Reitter, 1902 , is proposed as a junior synonym of Elaphocera .
