Xylophanes sp. (Hawk Moth sp.)

Description:

It resembles Xylophanes letiranti, but the creamy "tear drops" on the hindwing do not display the black speckles inside these tear drops associated with Xylophanes letiranti. In addition, there are no grey lines on thorax which are prominent on Xylophanes crotonis and Xylophanes letiranti. 
I found some discussions on the internet about this species found at El Dorado and it seems that this may be a species not yet described.
