Cladistic analysis of five DNA sequences in 107 species representing all the termite subfamilies, all six cockroach families, including 22 of the 29 subfamilies, and 5 of the 15 mantis families (as out-groups) showed that the termites are nested within the cockroaches, and that the Cryptocercidae is a sister group to the termites.
A análise cladística de cinco secuencias de ADN en 107 especies que representan todas as subfamilias de térmites, as seis familias de cascudas, que inclúen 22 das 29 subfamilias, e 5 das 15 familias de barbantesas (os denominados grupos externos ou out-groups) mostraron que as térmites están aloxadas dentro das cascudas e que os Cryptocercidae son un grupo irmán das térmites.
