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/author/Coca-Abia%2C+M+M> & 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’.
