Can you explain why this individual is in the sub-genus Metioche rather than Trigonidium or Trigonidomorpha. Does this male lack a stridulatory file?

I couldn't distinguish it between Trigonidium or Trigonidomorpha, so I thought it safer to keep it to Sub genus. Can you identify genus or species? It would be great if you can.

Sub-genus is a lower category than genus so it would be better to call it Trigonidium sp. but this would exclude Trigonidomorpha ssp. so Trigonidiinae sp. would be better. As Dave says 'its almost impossible to distinguish Trigonidomorpha sjostedtii from Trigonidium vitaticollis' so what hope have I got! But I do think its one or the other.
