New key to Chorisops

A new checklist of Italian soldierflies (Stratiomyiidae), by Franco Mason, has just been published:
http://www.pensoft.net/journals/zookeys … s-diptera-

As well as providing brief information on the 91 species recorded in Italy the paper includes a key to the five Italian species in genus Chorisops. This is clear and beautifully illustrated, and should be helpful in separating the two species we have in the UK (C. tibialis and C. nagatomii).

However, there appears to be a typo in the key to males. In couplet 3, the illustrations for C. nagatomii are given as "Figs 32-35", but on the illustrations themselves figs 32-35 as labelled as C. tibialis. The illustrations for C. nagatomii are figs. 28-31 (assuming that the illustration labels are correct, rather than the key couplet; I've sought clarification over this).

Thanks to Franco Mason for making this freely available via the ZooKeys open access journal, from Pensoft publishing.

Re: New key to Chorisops

That part of the illustration seems to be correct, so the text has the wrong reference to the figure numbers. More problematic seem to be the genital furca of the females. Mason's figure 42 (nagatomii) is a copy of what is figure 19-11 in Rozkosny's European revision which is labeled as tibialis. Mason's figure 43 (tibialis) seems to be a partial copy of figure 18-12 in Rozkosny's European revision which is labeled as nagatomii. Also, I am wondering which are supposed to be the rounded and pointed corners...

Re: New key to Chorisops

There is also a problem with couplet 2 with reference to figure 5 (should be 4?) and figure 6 (a female in the male keys). When I downloaded the keys today couplet 3 gives the figures for C. nagatomii as 28 - 31 not 32 - 35 as given in the original message. I think that I am too confused to want to use the keys.

Re: New key to Chorisops

You're quite right Brian, there do seem to be a large number of mismatches between the numbered references to figures given in the key couplets, and the figures themselves. What a shame.

It looks like the publishers have amended the error re figs. 32-35, so perhaps they can correct the others in due course.

Re: New key to Chorisops

I have contacted the editor with the request to publish an erratum and refered to this thread. I have received no reply, though...

Re: New key to Chorisops

The correction in the keys has been made, on-line there is now the right numbers of figures.
Thanks for the tip!

Re: New key to Chorisops

Franco, have the issues in posts # 2 and 3 also been addressed? In not, can you comment on them why that perhaps was not necessary?
