Good photos but I will pass and let Theo comment on this one because they are a difficult group. Having the specimen in the hand to manipulate and view the back of the head from slightly different angles is quite invaluable ... the black bristles on the back are very confusing unless you have both examples (positive & negative) to compare it with. Basically both couplet options will have small bristles on the back of the head but some have a few larger bristles mixed with them.

Let us first establish whether the hairs on sternite 1 are white or black .... ? Theo |

Not easy with the light LED, many reflections. I verified, they are very short and dark. |

It seems to be consistent with haemorrhodalis. I can't be sure from pics only Theo |
