It seems that Dicranopalpus caudatus is now regarded as a separate species to Dicranopalpus ramosus, and has been recorded in the UK, making certain identification of D. ramosus from photographs problematic, although ramosus is more common.
Another species that looks problematic on Naturespot is Sylvicola fenestralis. S. fenestralis and S. cinctus (not currently included in Naturespot) can only reliably be separated by gen. det., and S. cinctus is the more common of the two in the UK, so again, identification from photographs is not possible, and our existing records may be unreliable if id'd from photos.
