Faunal Composition Analysis And Biogeography Studies On Meloidae From China (Coleoptera: Tenebrionoidea)

In this study,related literatures and other data had been collected extensively. Faunalcomposition analysis of Meloidae in china has been made after a list of Meloidae in chinahas been established,Then analyzed the distribution of species diversity of Meloidae inChina.The map of geographical distribution of Meloidae was drew and the areas of diversityand the endemic distribution of Meloidae was determined by using the software of SPSS andGIS. The order of formation of Meloidae in China’s zoogeographic area was analyzed in thispaper.So was the similarity of subregions.Cluster analysis method was used to discuss genus’or species’ relationship of Meloidae,based on Meloidae distribution data. The main results areas follows:1. The Meloidae’s diversity distribution center.There are2subfamily8tribe26genera202species live in China on record, accounts forapproximately6.73%of the worldwide recorded species.There are three fauna types inchina.Respectively,The ancient North,The Oriental, The Oriental-ancient North.Amongthem,The ancient North is the mian fauna type.The Tianshan subregion in Meng-Xinregion,The Southwestern mountainous district subregion in Southwest China region,TheQinghai Zangnan subregion in Qingzang region,The Eastern hills and plain subregion inCentral China region are the richness center and the diversity distribution center and hot zone.The Meloidae’s8tribes’ diversity distribution center:The diversity distribution center ofCerocomini Leach is Tianshan subregion in Meng-Xin region;The diversity distribution centerof Epicautini Denier is Southwestern mountainous district subregion in Southwest Chinaregion;The diversity distribution center of Lyttini Solier is Qinghai Zangnan subregion inQingzang region;The diversity distribution center of Mylabrini Laporte are Tianshansubregion in Meng-Xin region and Qinghai Zangnan subregion in Qingzang region;Thediversity distribution center of Meloini Gyllenhal is Qinghai Zangnan subregion in Qingzangregion;The diversity distribution center of Horiini Latreille are Huanghuai plain subregion inNorth China region and Southwestern mountainous district subregion in Southwest Chinaregion;The diversity distribution center of Nemognathini Laporte is Tianshan subregion inMeng-Xin region;The diversity distribution center of Stenoderini Selander areEastern hillsand plain subregion in Central China region and Western mountainous district subregioninCentral China region; besides,The diffusion and distribution order is from north to south,from high latitudes to low latitudes,we know Cerocomini Leach, Mylabrini Laporte, NemognathiniLaporte are more primitive,then the Horiini Latreille, Lyttini Solier, Meloini Gyllenhal,Stenoderini Selander, Epicautini Denier is the last.2. The cladistic analysis ofMeloidae’distribution in chinaThe PAE analysis result shows the order ofthe formation of Meloidae in China’szoogeographic area is: Northeast China region, Meng-Xin region, North China region,Qingzang region, Central China region, South China region, Southwest China region.theorder is both realted to the living habit of Meloidae and the Quaternary glaciermovements.During the Quaternary glacial,the quenching temperature cause the speciesextinction in the southern China,while the creatures in the northern china were lucky surviveand spread to the south when it was warmer.3. Cluster analysis between26genera of Meloidae in chinaThe result shows that Glasunovia Semenov, Sitaris Latreille, Cerocoma Geoffroy,Semenovilia Kuzin, Ctenopus Fischer von Waldheim, Rhampholyssa Kraatz, LydulusSemenov, These7genera are clustered together,their similarity index is1.000.Maybe this isbecause these genera contains very few species and they only distribute inTianshan subregionin Meng-Xin region.4. Cluster analysis of Meloidae’subregion distribution in chinaThe result shows that：1. Daxingan mountain and the Altai subregion in northeast Chinaregion and Tianshan subregion in Meng-Xin region are cluster together,that maybe becauseDaxingan mountain and the Altai subregion containsthe Altai,and the Altai and the Tianshanare very close,and the geomorphology types and climate types are very similar,so as thedistribution of plants and animals.Besides,most of the meloidaes distribute in Daxinganmountain and the Altai subregion are acutally found in Altai when establishing the database ofmeloidae.2.Qiangtang plateau subregion in Qingzang region and Songliao plain subregion inNortheast China region both cluster with no one.It is inseparable with its unique climate, soil,topography, etc.
