Stick Insect, Phasmid

Phasmid from the genus Rhamphosipyloidea but not sure of what species or this could be something new/undescribed as the island where I found it is rather remote and far away.
Pics#1, #2 and #3 are of adult famels, with variation in colours. They are adults based on the fully developed wings, but just half wings.
Pic#4 is of an adult Male, he is much smaller in size with full wings and capable of flight.
