Description Ear tips black, tail white. White phase differs from LEAM - longer, larger ears and base of hair has less gray.
Skull Characteristics Distinguish from LEAM by anterior projection of supraorbital process and larger size. Compared to LECA, skull and rostrum broader, less tapered, and posterior of supraorbital process usually shorter and not fused to squamosal. LECA and LETO cannot be reliably distinguished by skull alone.
Notes While there are some subtle differences between the skulls of LECA and LETO, these species cannot be reliably distinguished by skull alone.
