Geographic Distribution of Genera Microtermes ancistrotermes (Isoptera) and Notes on New Species From Yunnan,China

The species of Microtermes Wasmann and Ancistrotermes Silvestri distribute in Ethiopian and Indomalayan regions.Considerating the zoogeographical origins,the authors deduce:the ancestral species of the above two genera distributed in the Gondwanaland,with the earth drift,some species were brought to the Ethiopian and Indomalayan regions,through the speciation,forming the contemporary distribution patterns.
