By investigating the fauna of Formicidae in Urumqi and its vicinities, in this paper, it is reported that there are 37 species of Formicidae in these areas, belonging to 13 genera and two subfamilies. The 15 species of Formica L. and 6 species of Camponotus Mayr are the main fauna components, and the complex faunal composition of Formicidae include Palaearctic species, Neoarctic species and polytopic species. Among them, 30 are the Palaearctic species and account for 81% of the total. Meanwhile, the Palaeo species consists of Panto Palaearctic species, Mid Asian species, European species, Euro Central Asian species, endemic species, Mediterranean species, Euro Siberian species and Central Asian species, etc. The Panto Palaearctic species, which includes 12 subspecies, occupies 32.4% of the total and is higher than the proportions of other components. Of all the species in our records, the Formica pratensis Retz., Formica polyctena, Forster, etc., are mesophytic, inhabit mainly in the forest zones and grassplots; while xeric species, such as Cataglyphis aenescens and Proformica epinotalis K. Ug., inhabit mainly in deserts and semideserts. Messor clivorum Ruzs. is the dominant species, and inhabits extensively in Urumqi and its vicinities.
