Turtur ermanni
Bonaparte
Turtur ermanni
Bonaparte, 1856b
: 942
.
Now
:
Streptopelia senegalensis ermanni
(Bonaparte, 1856)
(e.g.
Dickinson 2003
, based on a revision by
Hartert 1916
; see also
Hartert 1920
: 1495) or
Streptopelia senegalensis cambayensis
(Gmelin, 1789) (
Gibbs
et al
. 2001
)
.
Type
series
:
Bonaparte (1856b: 942)
described this species on the basis of “les exemplaires de
Turtur cambayensis
, qui proviennent de Boukharie, au Musée de Berlin”, i.e. “specimens of
Turtur cambayensis
, that originated from Bukhara [region], in the Berlin Museum [=
ZMB
].” Subsequent authors interpreted this to mean that the
type
series was comprised of more than one specimen deposited in the
ZMB
(e.g.
Hartert 1916
: 83; Richmond s.d.). However, Bonaparte's statement is confusing for two reasons. First, there is no evidence that the
ZMB
possessed more than one
senegalensis
or similar species prior to 1856. The single specimen known from the
ZMB
was collected by Eversmann on
10 March
[=
22 March 1821
] at “Buchara” [= Buxoro,
Uzbekistan
], and it was listed among the birds received from Eversmann and published as
Columba aegyptiaca
(
Lichtenstein
1822
;
1823a
). Second, Eversmann's Boxoro specimen was not listed by
Lichtenstein
(1854: 82)
, nor was it registered in the
ZMB
Accession Catalogue (SF & JM, pers. obs. in 2008). The only indication that it was present in the
ZMB
in 1856, when Bonaparte visited the Museum (
Bonaparte 1856c
,
d
), is a notice in Bonaparte’s (1856b) paper. However, the specimen may have survived in the
ZMB
uncatalogued, perhaps as a mounted specimen (see below).
If
Bonaparte (1856b)
erred in writing of the
types
of
Turtur ermanni
in plural, the Eversmann Buxoro specimen would be the
holotype
of this form.
Bonaparte (1856b)
may have confounded one or more
ZMB
specimens from elsewhere with that from Buxoro, or he may have erred in stating that all the specimens were in the
ZMB
; in either of these cases
Turtur ermanni
may be a composite series of multiple taxa. Prior to the description of
Turtur ermanni
, Bonaparte
had made a two-month trip through European ornithological collections (
Bonaparte 1856c
) and he may have mixed up notes from different collections. Hartert (
1903–1922
) repeatedly criticized Bonaparte for making mistakes of this sort.
Type
(?):
ZMB
2000.11128. This specimen lacks data on its origin. E. Stresemann (label data, probably from the 1950s–1960s) assumed that this could be Eversmann's Buxoro specimen received in 1822 (
Lichtenstein
1822
) and described in 1823 (
Lichtenstein
1823a
). The specimen indeed looks aged, has been reworked from a mount to a skin, and morphologically agrees better with Middle Asian birds than other forms. Although there is no proof that it was in the
ZMB
in 1856, or that it is Eversmann's specimen, there is no evidence against Stresemann's assumption and thus this specimen could be a
syntype
or the
holotype
of
Turtur ermanni
Bonaparte.
Eversmann's specimen was a female, collected by him on
10 March
[=
22 March 1821
] at “Buchara” [= Buxoro,
Uzbekistan
] (
Lichtenstein
1822
, Nr. 53, sub
Columba aegyptiaca
;
Lichtenstein
1823a
: 133 sub
Columba aegyptiaca
).
Type
locality
: “Boukharie” (
Bonaparte 1856d: 942
). If the species was based solely on the Eversmann specimen, then the
holotype
originated directly from “Buchara”, i.e. Buxoro, Buxoro Province,
Uzbekistan
[
39.80°N
,
64.42°E
], which would thus restrict the
type
locality of this form. However, given the uncertainties with the definition of the
type
series upon which
Bonaparte (1856a)
based this species, and with the identity of
type
specimen(s), the original
type
locality may have been broader than indicated by
Bonaparte (1856a)
.
Remarks
:
Hartert (1916)
revised the subspecies of
senegalensis
, concluding that Middle Asian
ermanni
is similar to but larger than Indian
cambayensis
. He recognized both subspecies, and this has been accepted by most subsequent authors. However,
Gibbs et al. (2001
: 248) considered
ermanni
as inseparable from
Streptopelia senegalensis cambayensis
(Gmelin, 1789)
, and did not recognize it. The
type
series upon which
Bonaparte (1856b)
based his
Turtur ermanni
might have included specimens from different forms of
senegalensis
. If proven, designation of a
lectotype
or a
neotype
would be necessary to settle the taxonomic meaning of
Turtur ermanni
. Although
Bonaparte (1856b)
based this name at least in part on Eversmann's Buxoro specimen, and the application of
ermanni
to Middle Asian populations has never been doubted, no specimens have been unequivocally identified as belonging to the
type
series of
Turtur ermanni
, so we refrain from any nomenclatural act.
