Difficult, I have only a female for comparision, with more shiny body and thicker femora, also the long hairs at the antennae are strange for Trinophylum, I think your spm is more similar to Gelonaetha ?
Thank you Xaurus Sir. In Gelonaetha, elytral apex is armed with small spine, but in my specimen, apex is unarmed. It is also not going to Trinophylum also as third antennal segment is longer than first. confused.
