I found this note in:

http://www.juniper.net/techpubs/software/junos/junos73/swcmdref73-interfaces/download/if-types-monitor.pdf

"The logical interface lo0.16385 is a nonconfigurable interface for 
routing platform control traffic."

and in:

https://www.juniper.net/techpubs/software/junos/junos74/swcmdref74-interfaces/html/loopback-if-monitor2.html

"NOTE: Logical interface lo0.16385 is the loopback interface for the 
internal routing instance. Created by the internal routing service 
process, this interface facilitates internal traffic. It prevents any 
filter created on loopback lo0.0 from blocking internal traffic."
