I have another 8 Tachyporus specimens which I hope to add here in due course but I'm currently stuck with their IDs. In short, two are dark (one more so than the other) leading me to pusillus/scitulus. The length of the elytra suggests pusillus (which would be most likely) but I cannot make out any microsculpture on the elytra which pusillus should have. The rest might all be hypnorum, but again I can't make out any microsculpture on the elytra which I think is wrong? One is slightly larger than all the others, and surely must therefore be hypnorum (?), but I'm not convinced the smaller ones aren't as well if the lack of evident microsculpture isn't an issue. Some have pale palps and others darker, but some specimens differ in this respect from their respective photos taken while still alive. I can't make sense of the possible differences in elytral bristle positions.
