Hi
ooth of T. angustipennis look completely different. T. angustipennis' ooths just look like M. religiosa ooths. I will put a picture of a T. angustipennis ooths the next days.
I do not think your ooth looks too bad. I think it is fine. But I do not know from which species it is. But it could be a T. sinensis ooth, yes.
regards,
