Chloropeta icterina
Sundevall, 1850: 105
.
VERBATIM
TYPE
LOCALITY: “
Caffraria
.”
CURRENT STATUS:
Iduna natalensis natalensis
(A. Smith 1847)
;
Acrocephalidae (
Dickinson & Christidis 2014: 472
)
.
TYPE
LOCALITY:There is no indication in Sundevall’s original description(1850: 105) that the type series consists of more than
one specimen
. However, it is apparent in his acquisition journal that there were
two specimens
considered by him to be included in the type series.
Gyldenstolpe (1926: 65)
referred to NRM 568746 [6795] as a “type”; we treat this as a
lectotype
designation of this adult male collected
25 June
1840
in
Durban. The
only
paralectotype
was sent on exchange to
Berlin
in 1853, with collector given as
J. A. Wahlberg
, but no other information (and is present in the ZMB collection)
.
Sundevall’s acquisition catalogue lists
four specimens
of
Chloropeta
received from Wahlberg. However, as noted above, only two were included in the
type
series.
Sundevall (1850)
was of the opinion that
Chloropeta icterina
was not conspecific with
Chloropeta natalensis
A. Smith, 1847
, and that there were differences in the green and yellow colours on the skins and in measurements. Following the Code (Art. 72.4.1) “The
type
series of a nominal species-group taxon consists of all the specimens included by the author in the new nominal taxon (whether directly or by bibliographic reference), except any that the author expressly excludes from the
type
series [Art. 72.4.6], or refers to as distinct variants (e.g. by name, letter or number), or doubtfully attributes to the taxon”. Since Sundevall did not include the other
two specimens
in what he thought of as a new species at the time of writing the description, they cannot be part of the
type
series.

COMMENTS: There is no entry in the journal for this day, but date and place are in line with other specimens collected at the same time.
