"The family Kalotermitidae is redescribed. The subfamily names 'Electrotermitinae' and 'Kalotermitinae' are placed in synonymy. The fossil genus Eotermes is removed from the family Kalotermitidae and placed in the family Hodotermitidae. 2. Three hundred and fifty-three species, fossil and living, are classified into 24 genera. Of these 24 genera, the following eight are new: Postelectrotermes, Ceratokalotermes, Comatermes, Incisitermes, Marginitermes, Tauritermes, Bifiditermes, and Bicornitermes. The genera Pterotermes, Proneotermes, Allotermes, and Epicalotermes are resurrected. The genus name 'Proglyptotermes' is relegated to synonymy. All the genera are described, and the generitype species are illustrated. 3. The generic classification is based on a constellation of conservative, adaptive, and regressed characters of both the imago and the soldier castes. 4. The phylogeny of the genera is discussed. The imago-nymph mandible indicates two main evolutionary lines. The first line is represented by the Proelectrotermes-Calcaritermes complex, and the second line by the Incisitermes-Cryptotermes complex. 5. Several cases of convergence are illustrated. In both the main lines of the family Kalotermitidae, the phragmotic head, the enlarged third antennal segment, and the slightly sclerotized median vein have all evolved independently many times. Also, the arolium has been convergently lost in many genera. 6. A discussion on conservative and regressed characters is included. Characters that show phylogenetic advancement or regression are also listed. 7. It is evident from the data on the hosts and Protozoa that the evolution of the genera of the Protozoa did not occur in conjunction with the evolution of the host genera and that the differentiation of the Protozoa genera took place before the differentiation of the host genera"--P. 400.
