[Taxacom] Costelytra zealandica - Epic fail!

Interesting that the authors say "it has not been possible to associate
either of the two species represented by the syntypes with known species
of Costelytra".  So there is not a useful  "Establishment of the identity
..." of the title.

This is odd biologically - if I understand correctly apparently the C.
zealandica of the syntype is not now known to exist (nothing corresponding
to a common Wellington (= Port Nicholson) insect of 1846 has been found
since anywhere in the country?). Is this likely, even given the extensive
native habitat reduction over the years?

If there was a mixup between the species known now I could see some need
for reconciling application of names.

Just to ensure that we are all on the same page on this: what the authors
have done is to dredge up the old (1846) type material for what is now
known universally as Costelytra zealandica (perhaps the most published
species name in all of N.Z. entomology!) and find that neither of the two
syntypes (there could be others) that they examined actually are that
species (i.e. the species  known universally as Costelytra zealandica). So
they have designated one of those syntypes as lectotype (thereby making
the name Costelytra zealandica definitely misidentified), and renamed the
infamous pest species as a new species Costelytra giveni. There is no
suggestion that they have even considered conservation of prevailing usage
as an option! Big sigh! Just to rub salt in the wound, the ZooBank
preregistration for the article just consists of an AUTHOR record filled
in as if it were a taxon record!

So, overall, it is one small step for the authors, and one giant leap
backwards for mankind!
