There are three bats which all look pretty much alike, the Jamaican fruit-eating bat, the intermediate fruit-eating bat, and the great fruit-eating bat. While there are small differences, they are most notably different in size, and I just listed them from smallest to largest if you didn't figure that out from the common names.
But none of these bats are small. The Jamaican fruit-eating bat can easily go 1.5 ounces, compared to a big brown bat in the US that on a good day might reach half that weight. The great fruit-eating bat is really quite a large animal, topping the scales at over 2 ounces with a wingspan of nearly 20 inches.
But, let's not jump to conclusions that this is, in fact a separate species of bat. All bats in the Genus Artibeus have been in the sights of the splitters and lumpers (those who tend to separate species and those who tend to lump things into one species) for many years. One currently accepted idea is that Intermedius is another name for Artibeus lituratus palmarum, and was split merely because it consistently falls on the lower edge of the size range for that bat. Enough said. This bat is whatever species/subspecies it is and it falls as Intermedus in my book however that is interpreted.
