Re: Psylloidea

Can you update the taxonomic information for Psylloidea please.  We had a request for records of Psylloidea, from someone who is setting up a national recording scheme.  We had some problems exporting the records, as the BPGS checklist gave only gave records of Trioza spp., while the Recorder 3 checklist only gave records of Psylla.  Neither checklist gave both.

Joe Botting, who is setting up the national recording scheme says that 'The Psylloidea are basically divided into the Psyllidae and Triozidae (with a few extra oddities), and for some reason only the triozids were listed as Psylloidea; the Psyllidae should be under Psylloidea as well, so you might want to add them to that level in the hierarchy. (I've had this problem with other RCs as well, where only one family was pulled up by the first search.)'

He also gave us some updated genus names:
Trioza alacris => Lauritrioza
Psylla hartigi => Chamaepsylla
Psylla pulchra => Cacopsylla
Psylla ambigua => Cacopsylla
Psylla mali => Cacopsylla

Thanks

Re: Psylloidea

Hi Ellie, I have been looking at these today and have a few observations and questions:

In the Species Dictionary the following are all marked as "species pro parte" and, as such are distinct recording taxa/entities, different to their alternative names. This means that usually we'd keep both as preferred names, unless the taxonomic expert can say for sure that all previous uses of these names in the UK definitely should be synonyms in the other genus. Would you be able to contact Joe and query that? I note that the NameServer does contain his new/modern names anyway but currently the p.p. names are listed separately for continuity with any older, less precise usage.

Psylla hartigi => Chamaepsylla
Psylla mali => Cacopsylla
Psylla pulchra => Cacopsylla

Now the good news:
Psylla ambigua => Cacopsylla - this seems to have been done already (TVK=NHMSYS0020705836)

Thanks, Chris R.
