The Fauna And Taxonomy Of The Family Formicidae(Insecta: Hymenoptera) From Jilin Province

In the reseach work, the author made a system collecting of the family of insects from August 2005 to November 2007. 1 national level, 2 provincial level of nature protection reservations and many villages and towns in forest regions were vistited. Totally, more than 5,320 ant specimens were collected over these sites during the period, and over 4,500 were soaked in ethyl alcoho. On the basis of these specimens, I conducted a careful morphological identification. The author made a key to species of Formicidae in Jilin based on worker major.By morphological Identification and fauna analysis, the results are as follows:(1)A total of 31 species, 3 subfamilies and 11 genera were recognized and described in the present these for the Formicidae fauna of Jilin. In the 3 subfamilies, Ponerinae is making up 3.22% of total species, Myrmicinae is making up 22.58% of total species, Formicinae is making up 74.19% of total species.(2)17 species were recorded for the first time from Jilin, they are: P. Luteipes Mayr, M. pharaonis L., M. Aciculatus Forel, L. galeatus Wheeler, P. rothneyi Forel, C. quadrinotatus Forel, L. fuliginosus Latreille, F. longiceps Dlussky, F. Altayensis, F. gagatoides Ruzsky, F. pratensis Retzius, F. approximans Wheeler, F. polyctena Foerster, F. sinensis Wheeler, F. sinae Emery, F. cunicularia Latreille, C. Aenescens Nylander.(3)In the faumistic analysis, based on the natural environment, the typical distribution characteristics of species, the administrative geographical region of Jilin Province was divided into 3 natural biogeographical regions for Formicidae fauna: the Eastern Mountain area, Central Hills area, Western Plains area. In this three areas, 21 species are in the Eastern Mountain, making up 67.74%; 23 species are in the Central Hills, making up 74.19%; 26 are in Western Plains, making up 83.87%. Among three areas, there are 18 species, making up 58.06%.(4)Among the 31 species described, 26 occur only in Palaeartic Kingdom, making up 83.87%; 18 occur only in Oriental Kingdom, making up 58.06%; 16 occur both in Oriental and Palaeartic Kingdom, making up 51.61%.
