Freshly emerged specimen with exceptionally bright and purple colors. I did not change the color on this photo or edit it strongly, besides a small crop and a hint of brightness. I have also added the original, unedited photo.
I spotted this on the wall of the guesthouse at Baobeng Fiema monkey sanctuary. Thanks to experts Latimeria, bayucca and Roy Goff for confirming that this is D. nerii.
