Prionops retzii
Wahlberg, 1856: 174
.
VERBATIM
TYPE
LOCALITY: “
In arboribus altis
in familias congregati (8–10) ad
flumen Doughe.
”
CURRENT STATUS:
Prionops retzii retzii
Wahlberg, 1856
;
Vangidae (
Dickinson & Christidis 2014: 212
)
.
TYPE
MATERIAL:
The
description was based on many specimens (cf. verbatim type locality above).
According
to
Sundevall’s
acquisition catalogue, four of these were sent to
Sweden
.
If
there were more specimens available to
Wahlberg
, we assume they are lost.
Gyldenstolpe (1926: 39–40)
referred to NRM 568742 [11734] as a “type”, treated here as a
lectotype
designation of this adult male collected
3 Aug 1855
near
Okavango River
. The
three paralectotypes
are: NRM 90171388 [11737], a young male collected
3 Aug 1855
near
Okavango River
; NRM 554138 [11735], a young female collected
23 July 1855
near
Okavango River
; and a young male [11736] also collected
23 July 1855
near
Okavango River
that was sent on exchange to
Berlin
in 1870 (but not found in the ZMB collection)
.
VERIFIED
TYPE
LOCALITY:
Okavango (Doughe) River
between
Lake Ngami
,
Botswana
and a place called Libebe (= Andara,
Caprivi
Strip),
Namibia
.
COMMENTS: Localities where Wahlberg camped in
Botswana
are very difficult to identify. His travels and camp sites were summarised by
Gyldenstolpe (1934)
and
Brinck (1955)
, but many of the sites lack names or any reference to named places. From
July to October 1855
, Wahlberg and his companions travelled north along the Thaoge River, and then the
Okavango
River after passing the confluence between the Thaoge and Jao rivers. On 25 July the group passed Mapororo Lagoon and camped at or near the confluence of the Thaoge and the Jao (Ng-Gokha) Rivers, at a place called “Embana” (
Craig & Hummel 1994: 169
) (Embana River is a local name for the Thaoge near the
Okavango
/Jao junction; Wendy Borello, pers. comm.). The Thaoge River becomes the
Okavango
River at this point. The group continued north along the
Okavango
River, collecting a female
Prionops retzii
on 23 July, an African Palm-Swift
Cypsiurus parvus
on 31 July [erroneously labelled with the locality Molopo River (= Mapororo River)], and two more specimens of
Prionops retzii
(one of them the
lectotype
) on 3 August along the way. According to
Brinck (1955)
, the group eventually reached Libebe (= Andara,
Namibia
,
18° 40’ S
,
21° 27’ E
) on 14 August. The type locality for
Prionops retzii
is vague, but nevertheless the type locality suggested by
Gyldenstolpe (1926: 40)
is reasonable and should stand. The species was named after Professor Anders Adolf Retzius (1796–1860), who was married to Emilia Sofia Wahlberg, sister of J.A. Wahlberg and Peter F. Wahlberg, and one of the sponsors of Wahlberg’s expedition.
