TAXONOMY, NATURAL HISTORY, AND
ZOOGEOGRAPHY OF THE SOUTHERN AFRICAN
SHIELD COBRAS, GENUS ASPIDELAPS
(SERPENTES: ELAPIDAE)
Donald G. Broadley
In Africa, Aspidelaps scutatus has always been
called the Shield Snake or Shield-Nosed Snake,
whereas A. lubricus is known as the Coral Snake
(F.W. FitzSimons 1912; V. FitzSimons 1962; Spawls
and Branch 1995; Visser and Chapman 1978). Frank
and Ramus (1995) introduced the names Shieldnose
Cobra and South African Coral Snake respectively,
whereas Greene (1997) used Shield-Nosed Cobra
and Coral Cobra. In a study of the phylogenetic relationships
of elapid snakes, Slowinski and Keogh
(2000) found significant bootstrap support for a core
cobra group consisting of Naja, Boulengerina,
Paranaja, Aspidelaps, Hemachatus, and
Walterinnesia, but excluding Elapsoidea and
Dendroaspis. Thus, in an attempt to stabilize common
names for these snakes, we propose to use
Shield Cobras for the genus, a direct translation of
the scientific name. Aspidelaps l. lubricus then
becomes the Coral Shield Cobra, A. l. cowlesi
(including A. l. infuscatus) is the Namibian Shield
Cobra, A. s. scutatus is the Kalahari Shield Cobra, A.
s. intermedius is the Lowveld Shield Cobra, and A.
s. fulafula is the Eastern Shield Cobra.
