Unless one thinks the light head and black collar are figments of the photo, or aberrant, it can't be Conoeca guildingi. It's probably a Lepidoscia, but I haven't looked for light heads there.
On Bold Systems 4 some C. guidingi have a light head. On Lepidoptera Butterfly House there are two photos of C. guildingii males with a light coloured head. Females are shown as being more uniform in pattern with a dark head. The suggestion was made on the basis that this is male.
