A totally enigmatic specimen from Cameroon which does remember some Callidiini. Blackish dark brown, also ventrally, with strong green reflections on elytra and pronotum.
It should belong to Saphanidus Jordan, 1894 (Xystrocerini), a genus related to Metallyra. Nonetheless, I am not completely sure since Adlbauer described an extremely similar, monobasic genus (Gabunsaphanidius) basing it on apparently specific characters.
