Reconstructing the past of Cryptocercus (Blattaria: Polyphagidae): phylogenetic histories and stories
1999
Grandcolas, P.
Recent phylogenetic studies showed that the genus Cryptocercus belongs to the subfamily Polyphaginae. This result is well supported by the total congruence between these analyses which were independently carried out on morphology and on neuropeptides from corpora cardiaca. Other recent studies contradict each other and are based on incorrectly defined characters or inappropriate methodologies. Preconceived ideas concerning Cryptocercus (primitiveness, relict distribution) definitely need to be confronted with facts. Facts indicate that Cryptocercus has a surprisingly high dispersal ability and that its present preferenda and distribution suggest a late Tertiary origin. Speculations about unwarrantedly clock-like evolution and dubious fossil records should not be preferred to both congruent phylogenetic framework and facts.
