Study On Leptoconops Kerteszi Complex In China

Leptoconops kerteszi complex is the bigest complex in Holoconops.Because of its small diffience among species and distinguishing hard, all species of this complex were in confusion for a long time.In order to settle this difficult problem both here and abroad, Leptoconops kerteszi complex in our country was studied using epidemiological way.lamp,mosquito net, livestock web were used to comether Leptoconops,Stylebooks were maded by microscope and Canada balata enveloping slides.The main results as follows:1 One million samples from different place in our country had been tided, fifteen specoies of Leptoconops kerteszi complex had been founded.They were: L.(H.) borealis,L.(H.) binangulus,L.(H.) conulus,L.(H.) gallicus,L.(H.) geermuensis,L.(H.) helobius,L.(H.) noterophilous,L.(H.) riparins,L.(H.) tarlimensis,L.(H.) triquetrus,L.(H.) tuotuohea, L.(H.) dunhuangensis,L.(H.) nasiformus,L.(H.) jizhangi,L.(H.) ningxiaensis .They occupies fifty percent in totle Holoconops in our country(15/ 30),thirty percent in totle Leptoconops(15/ 42).2 Identifing the subtile structure of clasper,9-tergum and 9-aterna.Different species'style and it's processes of Leptoconops kerteszi complex had different character in shape,size,whether there was setae under the processes.The 9-tergum's submedian processes,shape,steae on it,number,location and 9-sterna's gravure width,depth,whether there was setae on the film were different. The subtile structure of male insect's clasper,9-tergum and 9-sterna of Leptoconops kerteszi complex has a regularity and it has some value for distinguishing among species.3 Different species'apical dilation of parameres and aedeagus of Leptoconops kerteszi complex had different character in shape,size,whether there was process in interior and exterior margin,process'number,location , whether there was keratose or not,its location,extent.character changing of aedeagus was similar to apical dilation of parameres mentioned above,added if there was speckle at the top,speckle's shape and size.4 Female species'distribution of L.kerteszi complex in china was recorded.Their spermathecae's number,shape,size,whether there was short net basally and maculation in the end,its sclerous degree,the ration to length and breath were difference,expanded level,shape...
