The median teeth of mentum is very prominent, also the mental extesion is well developed. I can not see clearly whether or not the middle teeth is lower than other or not, it looks like Diamesa bertrami or Arctodiamesa sp? I am not sure, the mentum is not very clear, but it looks like an IV instar larva.
