EUGENE M. MCCARTHY, PHD GENETICS
To the author's knowledge, the following is the only information bearing on hybridization in this family:
Dasypus hybridus [Southern Long-nosed Armadillo]
× Dasypus novemcinctus [Nine-banded Armadillo] Benirschke (University of California, San Diego) says these armadillos have “the same number and appearance of chromosomes and could conceivably be subspecies. There are also many specimens with intermediate numbers of bands (7-9) known.” McBee and Baker (1982, p. 1) also note that both D. hybridus and D. septemcinctus sometimes have 8 bands. However, the author has not as yet encountered any explicit report of hybridization. Internet Citations: UCSD.
