Thanks for pointing this out. Yes, indeed; firstly the size is only 3.1-3.3mm (for the 4 specimens that I have), way smaller than gahani (6mm). Could it be affini, which is said to be 4mm?
I couldn't obtain the original description of affini. Anyone has a copy? BREUNING Stephan, 1938. Nouveaux Cerambycidę (Col.) Novitates Entomologicę, Paris 9: 30-63, 24 figs.
