Longhorn Beetle

Description:

This is a Longhorn Beetle of the family Cerambycidae and it looks like it belongs to the genus Gnoma. When I first attempted to identify it, I thought it was Gnoma luzonica Erichson, 1834, but on compairing it with a confirmed specimen of that species, already in my own compilation of local biodiversity, I quickly realized that this was not correct. In https://lamiinae.org/subgroup-44086-390.... the following six species are listed for Philippines: G. luzonica Erichson, 1834, G. suturifera Schwartzer, 1929, G. vittaticollis Aurivillius, 1923, G. jugalis Newman, 1842, G. suturalis Westwood, 1832, G. pulverea Pascoe, 1866. I can rule out luzonica, jugalis & pulverea because I have the first in my own catalogue and the latter two, pictured in lamiinae.org do not match my pictures shown above.

Habitat:

Spotted resting on a Button Orchid (Dischidia sp.) in our front yard. To be a little more informative, I should mention that I live in a small barangay (village) in a remote part of the Philippines. The surrounding area consists mostly of rice fields and patches of tropical forest. A short distance away there is extensive mangrove along the shores of the South China Sea. I suppose that any or all of these factors might assist in identifying this beautiful little creature.

Notes:

I would be grateful for help in identifying this one. I am pretty sure it must be G. suturifera, G. vittaticollis or G. suturalis. I would be grateful for any help with this.
