Type
series.
Hemprich and Ehrenberg (1833: 52)
stated “Specimina 7 adsunt eaque in Aegypto superiore, Arabia septentrionali et
Syria
accisa sunt” (“Seven specimens were collected in Upper
Egypt
, northern Arabia [= Sinai] and
Syria
”). At least four of these specimens were juveniles in “autumnal” plumage (
Hemprich & Ehrenberg 1833: 52
). These seven specimens thus form the
type
series of
Saxicola rostrata
Hemprich & Ehrenberg.
The identification of these
syntypes
is difficult, however, because no specimens were listed as
rostrata
by
Lichtenstein
(1825
,
1854
) or in the Inventory Catalogue of the
ZMB
, and the description of
rostrata
fits well also Hemprich and Ehrenberg’s (1833: 54) description of
libanotica
. Dresser and Blanford (1874: 339) found no
types
of
rostrata
in
ZMB
in 1873 (see also Blanford & Dresser 1874: 241).
Stresemann (1962: 387)
included in
rostrata
all
syntypes
of
libanotica
(see above), because he incorrectly believed that
rostrata
was composed from
libanotica
(adults) and
picta
(juveniles), as well as—apparently in error—also several
syntypes
of
Sylvia semirufa
Hemprich & Ehrenberg
(Lichtenstein’s 1825 specimens Nr. 109–115), but this does not mean that he considered these specimens to be
types
of
rostrata
in the sense of the
ICZN
(1999)
. We found no specimen from “
Syria
” in
ZMB
that would qualify as a
syntype
of
rostrata
(see “Remarks” for further data). On the other hand, we found two juvenile specimens from
Egypt
that could be
syntypes
of
rostrata
, although we were unable to obtain proof for this. They are listed below.
Syntype
(?):
ZMB
22083, skin, 3 [= juv.], collected in September [1821] at “Benisuef” (label) [= Banī Suwayf,
Egypt
;
29.06°N
,
31.09°E
]. This species was labeled as a “
Typus
” of
rostrata
.
Syntype
(?):
ZMB
4733, skin, 3 [= juv.], collected in September (year not given) in “
Aegypten
” (label) [=
Egypt
]. This specimen is morphologically very similar to the specimen
ZMB
22083. It was labeled as a “Typ” of
longirostris
Ehrb., which is either an unpublished Ehrenberg name or an error.
Type
locality.
The
syntypes
of
S. rostrata
were collected “in Aegypto superiore, Arabia septentrionali et
Syria
” (
Hemprich & Ehrenberg 1833: 52
), i.e. in the Upper
Egypt
, Sinai Peninsula and northern
Lebanon
.
Remarks.
In 2007, in ZMB we found the skin of an adult male from “
Syria
” (ZMB 14871) labeled as the
type
of
rostrata
. This specimen differs from other Mediterranean
Oenanthe oenanthe
(Linn, 1758)
in having the bill shorter (!), while
rostrata
was described as having the bill longer. We thus do not include this specimen among the
syntypes
of
rostrata
.
The fate of the species-group name
rostrata
of
Hemprich and Ehrenberg (1833)
depends on the taxonomic treatment of
Oenanthe oenanthe
. No nomenclatural problems arise when Mediterranean populations are united with the birds from continental Europe in a single (nominotypical) subspecies (e.g.
Vaurie 1959b
,
Loskot 1973
,
Sibley & Monroe 1990
,
Panov 2005
; see also
Ripley 1964
). However, several authors recently separated Mediterranean birds at the subspecies level, applying the name
libanotica
of
Hemprich and Ehrenberg (1833)
to them (e.g. Mackworth-Praed and
Grant 1951
, C. S. Roselaar in
Cramp 1988
,
Dickinson 2003
,
Collar 2005
). Eastern Mediterranean birds have longer bills than western Mediterranean birds of the same subspecies and also than European
Oenanthe oenanthe
of the nominotypical subspecies (C. S. Roselaar in
Cramp 1988
; see also Zedlitz 1912,
Meinertzhagen 1920
,
Ticehurst
et al.
1926
,
Stresemann 1943
), which suggests that both
libanotica
and
rostrata
of
Hemprich and Ehrenberg (1833)
were based on locally breeding birds, not on northern migrants.
Kleinschmidt (1905a: 166)
separated these birds taxonomically, applying the name
rostrata
to them and placing
libanotica
in its synonymy (see also
Kleinschmidt 1905b
: 6;
Hartert 1910
: 681); his choice of one of two simultaneously published names can thus be interpreted as a first reviser action (
ICZN 1999, Art. 24.2
). If eastern Mediterranean or all Mediterranean populations are taxonomically separated from the nominotypical subspecies, then the name
Oenanthe oenanthe rostrata
(
Hemprich & Ehrenberg, 1833
)
should be used, based on
Saxicola rostrata
Hemprich & Ehrenberg, 1833
. The name
rostrata
was applied to these birds already by a variety of earlier authors (e.g.
Zedlitz 1911
: 591, 1912: 556,
Weigold 1912
: 404,
Le Roi 1923
: 198,
Ticehurst
et al.
1926
: 103,
Friedmann & Loveridge 1937
: 245,
Portenko 1938
,
1954
: 161,
Stresemann 1943
: 489, 1962: 387,
Gladkov 1954
: 494–495). The preference for
libanotica
may have been caused by Erlanger’s (1905: 747) and Meinertzhagen’s (1930: 263, 1954: 241) unsupported assurances that
rostrata
is synonymous with the nominotypical
O
. oenanthe
(see also
Vaurie 1949
), while
libanotica
represents a valid form.
