Evolution and Systematics
Discussion of Phylogenetic Relationships
Boudreaux (1979), Thorne & Carpenter (1992), DeSalle et al. (1992), Kambhampati (1995), and Wheeler et al. (2001) argue for a sister group relationship between mantids and cockroaches:
====== Isoptera (termites) ===| | === Mantodea (mantids) ===| === Blattaria (cockroaches)
Hennig (1981), Kristensen (1995), Klass (1998), and Lo et al. (2000) favor a sister group relationship between termites and cockroaches:
====== Mantodea (mantids) ===| | === Isoptera (termites) ===| === Blattaria (cockroaches)
The monophyly of cockroaches has often been questioned, and many authors believe that the Blattaria are paraphyletic with respect to the Isoptera. In particular, a sister group relationship between Isoptera and Cryptocercus wood roaches has often been suggested (e.g., McKittrick 1964, Hennig 1981, Lo et al. 2000).
