What is mtDNA perspective of chromosomal diversification and hybridization in Peters’ tent-making bat (Uroderma bilobatum: Phyllostomidae) about?

## Abstract We compared sequence variation in the complete mitochondrial cytochrome__‐b__ gene with chromosomal and geographical variation for specimens of Peters’ tent‐making bat (__Uroderma bilobatum__). Three different chromosomal races have been described in this species: a 2__n__ = 42 race from South America east of the Andes, a 2__n__ = 44 from NW Central America and 2__n__ = 38 from the rest of Central America and NW South America. The deepest nodes in the tree were found within the South American race (42 race), which is consistent with a longer history of this race. Average distance among races ranged from 2.5 to 2.9%, with the highest amount of intraracial variation found within the 2__n__ = 42 race (1.7%), intermediate values within the 2__n__ = 38 race (0.9%) and lowest within the 2__n__ = 44 race (0.5%). Variation among chromosomal races accounted for over 55% of molecular variance, whereas variation among populations within races accounted for 6%. The 2__n__ = 38 and 2__n__ = 44 races hybridize in the coastal lowlands of Honduras, near the Gulf of Fonseca. Introgression between these two races is low (two introgressed individuals in 45 examined). Clinal variation acro
