[Taxacom] Costelytra zealandica - Epic fail!

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!

of the identity of Costelytra zealandica(White 1846)
(Coleoptera: Scarabeidae: Melolonthinae) a
species commonly known as the
M. M. Coca-Abia <http://www.tandfonline.com/author/Coca-Abia%2C+M+M>
White (1846) described
*Rhisotrogus* *zealandicus* from two syntypes,
however no lectotype has since been designated.
When the genus
1952 was described, with *Rhisotrogus
zealandicus* White 1846 as its type
Given’s description of this species was based on 400
collected at different localities
in New Zealand as White’s syntypes were
not available to him. Later, Given (1960)
examined one of the syntypes,
it was identical to specimens he used to describe
*C. zealandica*, but a lectoype was not
designated at this time. So, the
this paper are: (i) to provide a detailed description of
external morphology, mouthparts and male
genitalia based on the syntypes of
zealandicus*; (ii) to compare these type specimens with the
by Given (1952); (iii) to
compare the syntypes to establish if they are
conspecific; (iv) to designate an appropriate
lectotype and (v) to study a
series of *C. zealandica* collected from throughout New
Zealand to establish the status of the taxon
currently known as
Differences between the syntype specimens, and Given’s
(1952) description of the New Zealand specimens
were found. In addition,
are not conspecific. As a result *Costelytra giveni* n.
sp. is established and described to represent
the species currently known
as the ‘New
Zealand grass grub’.
