[Taxacom] Costelytra zealandica - Epic fail!

I wish it were that simple, John! Unless someone does something to stop it, the new name is going to get harvested by NZOR and then to all the other aggregators like GBIF, etc., and it will then look as though it has been "accepted by consensus". Most entomologists, around here anyway, don't understand the Code sufficiently well to be able to see that there is no need for the name change and every reason not to change it (or else this article would not have gone through peer review unchallenged). There are certain parallels here with the generic split of Nothofagus. It suited the authors to do the split, and nobody else wants to rock the boat. The authors are busily flloding the literature and online databases (which they have control over) with instances of the new names, again to give the impression of "consensus".

 Fortunately anyone with any sense can just stick
 with the established name.

 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!

  Establishment
 
  of the identity of Costelytra zealandica(White 1846)
 
  (Coleoptera: Scarabeidae: Melolonthinae) a
 
  species commonly known as the
 
  New Zealand
 
  grass grub
 
  M. M. Coca-Abia <http://www.tandfonline.com/

  & J.

 author/Romero-Samper%2C+J>
 
 
 
  White (1846) described
 
  *Rhisotrogus* *zealandicus* from two syntypes,
 
  however no lectotype has since
 been designated.
 
  When the genus
 
  *Costelytra* Given
 
  1952 was described, with *Rhisotrogus
 
  zealandicus* White 1846 as its type
 
  species,
 
  Given’s description of this species was based on 400
 
  specimens
 
  collected at different localities
 
  in New Zealand as White’s syntypes were
 
  not available to him. Later, Given (1960)
 
  examined one of the syntypes,
 
  stating that
 
  it was identical to specimens he used to describe
 
  *C. zealandica*, but a lectoype was not
 
  designated at this time. So,
 the
 
  aims of
 
  this paper are: (i) to provide a detailed description
 of
 
  the
 
  external morphology, mouthparts and male
 
  genitalia based on the syntypes of
 
  *R.
 
  zealandicus*; (ii) to compare these type specimens with
 the
 
  description
 
  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
 
  representative
 
  series of *C. zealandica* collected from throughout
 New
 
  Zealand to establish the
 status of the taxon
 
  currently known as
 
  *C. zealandica*.
 
  Differences between the
 syntype specimens, and Given’s
 
  (1952) description of the New Zealand specimens
 
  were found. In addition,
 
  White’s syntypes
 
  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’.
