title: Taxonomic studies on the ant genus Cerapachys Smith (Hymenoptera, Formicidae) from India.
abstract: The Indianspeciesof the ant genus Cerapachys Smith are keyed. Twelve species are recognized of which 6 are described as new. The species are: Cerapachys aitkenii Forel, Cerapachys alii sp. n., Cerapachys anokha sp. n., Cerapachys besucheti Brown, Cerapachys biroi Forel, Cerapachys indicus Brown, Cerapachys longitarsus (Mayr), Cerapachys nayana sp. n., Cerapachys schoedli sp. n., Cerapachys seema sp. n., Cerapachys sulcinodis Emery and Cerapachys wighti sp. n. Geographic distribution and group affinities of the new species are discussed. A revised key to the Indian species is provided. The rare ergatoid queens of Cerapachys nayana, Cerapachys schoedli and Cerapachys seema are reported. Formed in response to selective pressures these ergatoid queens have a significant role in dispersal strategies and contribute much to our understanding of the biology of these ants.
