Stick Insect, Phasmid - Calvisia (Viridocalvisia) marmorata

This is a pair of Stick Insect, Phasmids - Calvisia (Viridocalvisia) marmorata.
They are high level of sexual dimorphism. The smaller plain brown in the picture is the Male and the Female is the bigger brightly coloured one.
It was originally described from a Male specimen as Nescicroa marmorata and the Female to the genus of Calvisia. In the recently published book, A Taxanomic Guide to the Stick Insects of Borneo by Dr. Francis Seow Choen, he corrected the description and placed them under the genus of Calvisia and erected a new sub-genus of Viridocalvisia.
